      <abstract>
        <p>In this paper, we investigate how a digital badging system was used as part of an informal, not-for-credit professional development project. Teacher Learning Journeys was designed for personalized science learning for educators in K-12 schools, museums, universities, and teaching colleges through employing two levels of micro-credentials: lower achievement digital stamps and higher achievement digital badges. Researchers conducted a qualitative collective case study centered on 36 teachers; the primary data were records from learners' interactions within the digital badge system; secondary data came from a survey at the end of the experience and two interviews with 11 focal teachers. Findings suggest the following design principles: (a) two levels of assessment can support personalized learning, (b) mastery of learning can be demonstrated and assessed through reflective logs, (c) collaboration during and after badging activities can provide value to the learners, and (d) establishment of relevance of badging experiences can support the application of content outside the badging system.</p>

        Digital badges have been used in social media and online
games in five key areas identified by Antin and Churchill
[
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]: (a) setting goals and providing feedback on goal
achievement, (b) providing instruction about what activities
are possible, (c) building a user’s reputation based on
interests, (d) serving as a status symbol and documenting
achievements, and (e) showing affiliation with a
community. As digital badges have been used increasingly
in education, three of these five gaming categorizations
from above have been conceptualized as important for use
in learning environments: (a) rewarding and motivating
achievements, (b) credentialing or recognizing learning
(with badges serving as micro-assessments), and (c) acting
as markers that learning has occurred for learners
themselves, the learners’ teachers or mentors, and the
learners’ peers [

        ], [

      <title>1.1 Research Findings on Badges within</title>
    </sec>
    <sec id="sec-3">
      <title>Educational Systems</title>
      <p>While many types of educational institutions are adopting
digital badges, empirical research studies (qualitative,
quantitative, or design-based investigations) into how
digital badges (and now Open Badges) support learning
have only recently been published. Because the research is
new, themes on the role of digital and Open Badges in
education are emerging.</p>
      <p>
        Through an analysis of 30 badging projects funded by the
Badges for Badges for Lifelong Learning Competition
(funded by the MacArthur Foundation) Hickey et al. [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]
offer numerous design principles for recognizing,
motivating, assessing, and studying learning with digital
badges and within badging systems. Six of these design
principles are related to our inquiry: (1) support learners to
set goals related to the badging activities, (2) map learning
trajectory through badge display pages and badging
activity logs, (3) promote collaboration through the
discussion of personal backgrounds and experience in the
subject matter, (4) use hierarchy of badges or leveled badge
systems, which suggests learners pick interlocked content
and decide their level of assessment, (5) use mastery
learning to focus on awarding badges to learners who
reflected on their activity and described how they might
implement it in the future—outside the badging system,
and (6) enhance the badges’ validity with expert judgment,
which asserts that master practitioners or other experts can
be used to review the work of learners and to act as
mentors.
      </p>
      <p>
        In research with 51 middle school pupils (seventh and
eighth grade) who were learning science, technology,
engineering, and math (STEM), Abramovich, Schunn, and
Higashi [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ] investigated the interaction of badges with
learners’ prior knowledge and motivation. To accomplish
their study, the team designed two types of digital badges:
one was awarded for participation (without regard for
learning outcomes) and the other was awarded for
demonstrated mastery of STEM skills (as an assessment).
Abramovich et al. found that learners were motivated
differently by the badges. Participation-only badges were
earned eventually by every student and had little to no
impact on learning and motivation. In the case of the
skilloriented badges, the more skill badges earned, the more
those learners expected to be successful in mathematics.
The authors concluded that learners who earned the least
number of skill-oriented badges also had less expectation
for STEM content learning success than those who earned
more skill-oriented badges.
      </p>
      <p>From their study, Abramovich et al. make two
recommendations to the design of badging systems. First,
they suggest that to maintain high levels of learner
motivation badging system designers include few
participation-only badges and have many skill-oriented
digital badges available. Second, based on an analysis of
survey data, Abramovich et al. suggest the provision of
instructions on the criteria needed to earn a badge will also
assist to keep motivation high.</p>
      <p>
        While much of the research has occurred within STEM
learning environments, not all badges are focused on
STEM content. For instance, from their case study of
badges to support self-regulation in an online STEM
course, Cucchiara and colleagues [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ] developed interrelated
badges, in what they referred to as a “badge ecosystem,” to
incorporate technical and interpersonal (i.e., soft) skills.
These nontechnical badges were important aspects of the
holistic badge offering for this project.

      <title>1.2 Digital Badges as Pedagogical Tools</title>
      <p>
        Within the broader landscape of technology-enhanced
learning research, our research interests are aligned to
badges as pedagogical tools. Our perspective is that badges
can support learning and act as markers that learning has
happened. The recognition that learning has happened is
important not only for learners, but also for their teachers
and mentors, and their peers in the same learning
environment [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ], [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ]. In this way, we consider badges as
pedagogical tools used by learners and their teachers and
mentors to support informal learning.
      </p>
      <p>
        Hickey et al. [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ] have categorized the extant badging
research, into various types. Given the Hickey et al.
typology of badging research, our analysis falls into
research with badges and research of badges [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]. This
means that we are considering how to improve the impact
of badges in the learners’ lives (i.e., research of badges),
while we are also attending to the metadata within the
badging system to improve the badging experiences
(research with badges) [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]. Our research group has created
a series of projects to investigate digital badges as a means
for increasing learners’ choices and decision making within
and across informal, formal, and professional development
activities. Research with badges and for badges refers to
our intent to use badges to offer improvements for systemic
impact such as offering a mechanism to support
professional development needs.
      </p>
      <p>
        Our project’s overarching research goal is to examine
learners’ badge-earning pathways in order to refine
learning theory about how the things that learners learn in
one setting can be applied to another consequential setting
via computer tools. For example, our team’s prior work has
examined the role of: digital photography in supporting
learning across settings [
        <xref ref-type="bibr" rid="ref20">20</xref>
        ], mobile computers in
supporting meaningful conversations about science where
families’ prior experiences are made relevant to new
experiences in informal institutions, [
        <xref ref-type="bibr" rid="ref21">21</xref>
        ] and
technologically-enhanced web 2.0 tools in supporting
connections from community to school [
        <xref ref-type="bibr" rid="ref22">22</xref>
        ]. Our project
here builds on our team’s prior work of designing for
learning across settings. In addition, within this badging
project, we seek to develop design principles applicable to
improving the educational programming related to badges
and the badging system designs of badge issuers.
In this analysis, we focus on investigating the following
research question: How do learners interact with elements
of a digital badging system including the goal statements,
logs, materials submitted to earn a stamp or badge, and
their mentor? We answer this question through a tiered case
study analysis of 36 schoolteachers and with the in-depth
analysis of 11 of the 36 teachers. Of these 11 focal
teachers, we present a thick description of two teachers’
experiences—one teacher who represented a typical badge
system user and one teacher who represented an intense
user of badging.

      <title>2. TEACHER LEARNING JOURNEYS (TLJ) BADGING SYSTEM</title>
      <p>TLJ was created to support teacher professional
development (PD) in STEM subjects for K-12 education in
the United States. Teachers accessed the TLJ system to
engage in STEM learning at their own pace and to meet
their own identified needs and a level of depth that
reflected the needs of the pupils in their classrooms.</p>
    </sec>
    <sec id="sec-6">
      <title>2.1 TLJ’s Goal to Support STEM Learning</title>
      <p>In the first year of the TLJ system’s operation that is
presented here, educational badging options included 54
activities related to three areas of science and engineering:
solar system (19 badging activities), weather and climate
(20 badging activities), and engineering (16 badging
activities). The teachers earned badges by reflecting on
activities that they participated in; these badging activities
covered a wide-range of PD activities. PD activities used in
our badging program included synchronous webinars,
asynchronous discussion boards, educational media and
texts, archived online presentations by scientists, engineers,
and education experts. Figure 1 shows one of the 20
badging activities in the Weather &amp; Climate library.</p>
    </sec>
    <sec id="sec-7">
      <title>2.2 Features of the Badging System</title>
      <p>Teachers were introduced to the system through an
instructional video created by the principal investigator of
the project. This video elaborated on badges and each of
the functions available. Also, teachers were invited to use
as many of the available badging PD resources as they
wanted.</p>
      <p>The TLJ badging system was developed utilizing a travel
metaphor. TLJ helped teachers to set their unique learning
goals for their badging journey, find relevant badging
activities to support their goals, compose a log of their
experience for the activity that could be submitted to earn
badges, receive feedback from an expert as they continued
their journey, and store all of their badges
(accomplishments) in display pages styled to be similar to
that of the stamp inside of a passport.</p>
      <p>
        A teacher started their learning journey by creating a TLJ
account and writing a goal statement. While optional, the
goal statement was used to meet goal-setting needs by
helping the teacher to begin to articulate a learning pathway
[
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]. Next, the teacher could review all 54 PD badging
activities or search through them by topic or grade range
and decide which to add initially to their itinerary. Only the
teacher and the research team could access each itinerary.
In this section, the teacher could review the badging
activities they wanted to accomplish or remove badging
activities they no longer wanted to complete.
      </p>
      <p>The teacher then could initiate any PD badging activity
from their itinerary by attending a webinar or engaging in
other educational activities. In TLJ, no credit was available
just for participation; the ideas had to be applied to the
teacher’s educational setting. The teacher then chose to
submit their materials to earn a stamp or a badge, as
described in Section 2.3. A National Aeronautics and Space
Administration (NASA) education expert was assigned as a
mentor to the teacher based on the content area of the
badge. The mentor provided written feedback to the
teacher, which resulted in the (a) earning of a badge or a
stamp or (b) additional activities to be completed. The
feedback was stored in the system as part of the metadata
associated with their engagement with a particular activity
and could be accessed by the teacher, the mentor, and the
researchers. Then, the teacher’s itinerary would change to
show that the badge was earned.</p>
      <p>After earning a badge or stamp, the teacher would have the
option to anonymously fill out a survey on the activity,
which gave the research and development team valuable
feedback. The teacher would also be able to view the status
of their badges and stamps in portfolio pages for the earned
achievements. Additionally, any badges or stamps that
were being reviewed by mentors were also displayed with
the text pending superimposed on the badge image. The
teacher could also review their work in the log section. This
feature of TLJ acted as a blog-style page that captured each
entry the teacher made for the activities completed as well
as any additional evidence they uploaded for review by a
mentor or that they wanted to be included in their badging
portfolio.</p>
    </sec>
    <sec id="sec-8">
      <title>2.3 Features of the TLJ Stamps and Badges</title>
      <p>
        An important feature of the TLJ badges was that they were
leveled [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]. Once teachers selected the PD badging
activities from TLJ, they controlled their level of
engagement with the topic by adjusting the type of
microcredential sought for learning —  a TLJ stamp or TLJ badge.
A TLJ stamp reflects the teacher’s need for a more cursory
engagement with and consequent assessment of an activity.
The stamp is the lowest level badge. A TLJ badge is earned
for a higher level of mastery and shows a more in-depth
engagement with not only the STEM concept but also with
applying the STEM concepts to the teachers’ professional
settings. The TLJ badge is the highest-level badge, and for
the sake of clarity in the paper, we will only refer to the
highest level of badges as badges; the lower level will be
referred to as stamps.
      </p>
      <p>To illustrate the difference between badges and stamps, the
PD badging activity, Scale Models: The Earth-Moon
System in the Solar System is a good example. This Scale
Models activity has three options for teachers: (1) the
entry-level activity is earning a TLJ stamp (Figure 2 left);
teachers attend the webinar and write one brief reflective
post, (2) a higher level of mastery means earning a TLJ
badge (Figure 2 right), teachers also attend the webinar but
they write a full lesson plan on incorporating the content
into classroom activity, or (3), teachers can earn both the
TLJ stamp and badge for this Scale Models activity by
meeting both the stamp and badge criteria. To make the
stamp and badges visually distinct, the stamp was given a
design akin to a passport office rubber stamp and the badge
an embroidered patch as shown in Figure 2.</p>

      <title>3. THEORETICAL FRAMEWORK</title>
      <p>
        To support our analytical work, our theoretical framework
considers bringing together the concept of cultural tools
from sociocultural theory [
        <xref ref-type="bibr" rid="ref18">18</xref>
        ] with three dimensions of
mobile learning [
        <xref ref-type="bibr" rid="ref14">14</xref>
        ] (i.e., authenticity, collaboration, and
personalization). As such, we examine how badges and the
badging system acted as cultural tools to mediate the
teachers’ learning in regard to authenticity to relevant
STEM teaching and learning in K-12 schools, collaboration
with other teachers and mentors, and personalization to
their educational setting.
      </p>
    </sec>
    <sec id="sec-10">
      <title>3.1 Cultural Tools to Mediate Learning</title>
      <p>
        Vygotsky’s [
        <xref ref-type="bibr" rid="ref18">18</xref>
        ] work in sociocultural theory maintains that
learning requires people to use cultural tools with the help
of experienced others. Cultural tools are artifacts such as
physical objects, conceptual symbols (including language),
and representations that people use within goal-directed
actions [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ]. For example, within studies of
technologyenhanced learning, Cole [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ] describes three kinds of
artifacts that serve as cultural tools: (a) physical objects
(e.g., a computer, calculator, or hammer), (b)
representations and ways of acting, and (c) imagined
artifacts (e.g., games and art). In this way, cultural tools are
the set of resources available to members of a cultural
group to mediate meaning-making. In our work, we
consider how the badges and the badging system served as
cultural tools to mediate STEM meaning-making for
teachers along the dimensions of collaboration,
authenticity, and personalization, as described below.

      <title>Environments</title>
      <p>
        Our TLJ research and development was guided by a
framework for mobile learning [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ] because TLJ was
intended for use by learners as they moved across social
and technological settings—in their schools, homes, or
communities accessed by desktops, smartphones, tablets,
and other computers. While our prior work focused only on
the personalization dimension of mobile learning [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ], this
analysis focuses equally on authenticity (also referred to as
relevance), collaboration, and personalization because
when related to teacher PD, these three learning dimensions
address the prior critiques of ineffective PD [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ] and show
what is possible through digital badging systems.
      </p>
      <sec id="sec-12-1">
        <title>3.2.1 Authenticity</title>
        <p>
          In the Kearney et al. model [
          <xref ref-type="bibr" rid="ref14">14</xref>
          ], authenticity is a mobile
learning dimension comprised of two subcomponents:
contextualization and situatedness. Contextualization is
high when a learner is exposed to learning situations that
are perceived to be realistic or relevant [
          <xref ref-type="bibr" rid="ref4">4</xref>
          ] to their personal
or professional life. By making use of TLJ, teachers focus
on the specific PD badging activities that are relevant to the
topics and grade levels that they are teaching. This helps
teachers create an authentic context for the badges available
through the TLJ system. Situatedness is high when a
badging learning experience is related to or within a
community of practice [
          <xref ref-type="bibr" rid="ref19">19</xref>
          ]. This can be a full participation,
such as engaging in conversations with the fellow STEM
teachers, or the engagement can be a peripheral activity,
such as observing discussions of the high-engagement
webinar participants. This can also relate to the value of
badge as status to the community of practitioners within
which the teachers are engaged [
          <xref ref-type="bibr" rid="ref2">2</xref>
          ], [
          <xref ref-type="bibr" rid="ref3">3</xref>
          ], [
          <xref ref-type="bibr" rid="ref13">13</xref>
          ].

      </sec>
      <sec id="sec-12-2">
        <title>3.2.2 Collaboration</title>
        <p>
          With the emphasis of socio-cultural considerations,
cooperative, communicative, and collaborative efforts to
support meaning-making are included as a dimension in the
Kearney et al. [
          <xref ref-type="bibr" rid="ref14">14</xref>
          ] framework for mobile learning.
Collaboration is included in this framework to permit
learners multiple opportunities to articulate their
understandings as they engage with others in shared
meaning-making experiences. Conversation, both verbal
and written, provides for a valuable ongoing exchange of
ideas that support the development of STEM teaching
practices. In addition to shared meaning-making,
collaboration is meant to include the exchange of
information between learners and between learners and
mentors. Through providing collaboration, cooperation, and
communication opportunities, badge system designers can
encourage the learners to become more connected with
each other and share experiences. In the case of TLJ, this
sharing goes beyond STEM content to also include
information about student learning, needed resources (e.g.,
favorite web links), and even lesson plans that work within
local contexts.

      <sec id="sec-12-3">
        <title>3.2.3 Personalization</title>
        <p>
          Personalization is a dimension of mobile learning that
allows for learner-centered education because learners can
customize many factors related to their learning. Kearney et
al. [
          <xref ref-type="bibr" rid="ref8">8</xref>
          ] refer to personalization as a concept that supports the
“just enough, just-in-time, just-for-me” aspect of mobile
learning which can allow learners to create their own
pathway of learning. Agency [
          <xref ref-type="bibr" rid="ref15">15</xref>
          ], [
          <xref ref-type="bibr" rid="ref17">17</xref>
          ], a subcomponent of
personalization, is high when a learner is able to negotiate
and make decisions about their own education, such as
what subject matter to take and what goals to set. The
dimension of customization furthers personalization by
allowing the learner to select what they need to meet their
personal and professional goals. TLJ offers teachers the
ability to both set their learning goals and to meet these
goals by navigating through and choosing from available
PD activities. Each activity is a smaller part of what might
normally make up a larger workshop or course. This allows
teachers to customize what they spend time on to meet both
their personal needs and the needs of their workplace (and
pupils). While the field of educational technology might
also use the term personalization to refer to personalization
offered through data mining patterns generated by an
intelligent computer system, here, we use the term
personalization to refer to providing teachers with the
agency and the ability to customize.

      <p>
        The purpose of this paper is to understand the learners’
experiences with and through TLJ. We seek to use learner
badging artifacts and interviews to understand how the TLJ
teachers interacted with elements of a digital badging
system including the goal statements, logs, materials
submitted to earn a stamp or badge, and their mentor.
Hickey and team [
        <xref ref-type="bibr" rid="ref11">11</xref>

(both completed and in progress) into various types; our
research falls into the category of ‘research of badges’
where researchers “study the badge system’s impact and
integration into learners’ lives” (p. 57). Often, research of
badges use includes interviews, surveys, and data mining
[
        <xref ref-type="bibr" rid="ref11">11</xref>

by the categories shown in Table 1. The pre- and
postinterviews were conducted over the phone. Each interview
lasted 45 minutes to one hour. The questions were focused
on perceptions of TLJ and other experiences with features
of the badging environment and included: “Did you find
value in setting a purpose statement for your learning
journey?” “Did you find the itinerary an easy way to keep
track of your professional development activities? and “Did
you find value in the feedback you received from the

      <title>4.3 Case Study Structure</title>
      <p>
        The research team designed a strategic case study [
        <xref ref-type="bibr" rid="ref16">16</xref>
        ] at
three levels. At the first level of the case, the badging
records of all 36 teachers from year one were considered.
This level of analysis was investigated through the data
collected by the activity surveys, the post-TLJ survey, and
the system logs. Second, a more fine-grained analysis
examined 11 teachers who completed pre- and
postinterviews for year one of TLJ (shown in Table 1). These
interviews with teachers were used to ensure that
out-ofbadging data were used to enrich the analysis. To
understand learner intention and learner background, these
teachers serve to help contextualize the TLJ badging
system in greater depth.
badging system—in their classrooms, in their schools, and
in their lives.
Third, at the most fine-grained level, we sought to elucidate
learners’ complex interactions with the badges, stamps, and
the badging system within TLJ. To conduct this in-depth
analysis, two teachers were selected — one as an example
of average engagement in TLJ and the other as an example
of high-level engagement in TLJ. These two teachers were
strategically sampled as the typical user and the extreme
user. The first participant, Barbara, received a total number
of stamps and badges similar to the year one average. The
second participant, Sally, completed more than double the
average teacher. In this way, our examination includes both
a typical learner (Barbara) and a heavily involved learner
(Sally, see Figure 3). Both Barbara and Sally agreed to
participate in year one as part of their summer professional
learning and expressed enthusiasm when getting started.
They were selected in order to focus on two people with
similar backgrounds, yet they experienced different
learning journeys given their interests, expertise, and
personal goals as described in Section 4.4.

      <title>4.4 Data Analysis</title>
      <p>The team conducted an analysis of the TLJ experiences of
the 36 teachers that participated within the year one
implementation, which was run from June to August 2012.
Our analysis focuses on understanding learners’
experiences within the TLJ badging system and how these
experiences could be useful to interactions outside the
The analytical process began by iteratively reading the
records of 11 teachers who participated in the interviews.
We made this choice because we had data from outside the
TLJ system about their interests in badging, the STEM
content and their workplace conditions. The interviews
focused on the teachers’ experiences earning digital badges
and stamps, using the online badging system to support
learning, and how the overall TLJ experience connected to
their educational institution.</p>
      <p>As we read the 11 teachers’ goal setting statements, badge
activity logs, and interview transcripts, we applied codes
for personalization, collaboration, and authenticity. First,
the coded excerpts were examined within each case (e.g.,
one teacher’s experiences). Second, the coded segments
were compared and contrasted within an Excel spreadsheet
to understand patterns within the badging experience of the
11 focal teachers. We used the analysis of the 11 teachers
to strengthen our coding book and to develop preliminary
analytical insights before moving to the third step of the
analysis. In the third analysis step, we examined the logs
from earning badges and stamps and goal statements from
all participating 36 teachers. By looking at the full dataset,
we were then able to find examples and counter examples
of our themes. We then turned to the activity surveys and
summative surveys to compare the trends from the
teachers’ logs and reflections to survey responses.
Throughout the analysis process, we relied most heavily on
the badging activity logs and the goal setting reflections.
However, the interview data and survey responses allowed
us to triangulate our findings and to ensure we understood
the teachers’ experiences from their perspectives.</p>

      <title>5. FINDINGS</title>
      <p>In this section, we answer our research question about the
kinds of interactions learners had with the elements of the
TLJ badging system. Overall, the learners, who in this
study are teachers, reported an estimated average of 13.4
hours (range 2 to 40 hours) of engagement with TLJ
activities during the summer. We first describe the way that
the full group of 36 teachers used TLJ’s various
components, with explanatory details from the 11 interview
participants, especially the focal case study educators:
Barbara and Sally.</p>
    </sec>
    <sec id="sec-19">
      <title>5.1 Learning Organized by the Itinerary</title>
      <p>
        Each participant’s journey began with writing a personal
learning goal statement, which allowed support for teachers
in their personalized learning experience. In particular, it
helped in identifying the badged activities they would want
to complete over the summer and add them to a personal
itinerary. As Table 2 shows, learners identified over half of
the activities that they wanted to complete at the start of the
experience, yet completed very few. Across the 36
teachers, 221 activities were picked during the first few
weeks of the program, but only 11 were completed. Time at
the beginning was spent exploring and planning for the
options within the badging system, rather than earning
stamps or badges. This supports the motivating learning
principle to set goals described by Hickey and colleagues
[
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]. During year one, teachers were able to consider their
goals through drafting a focused statement and then
creating a learning trajectory [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ] for themselves by adding
activities to their itinerary. Table 2 also demonstrates
fluctuations in the engagement in PD over the time of the
first year of TLJ.
As evidenced by Sally and Barbara, setting more specific
and attainable goals may support teacher focus while
exploring, selecting, and completing PD activities. Barbara
focused her goals on engaging her specific class and grade,
stating that she wanted “to learn new and innovative
approaches to teaching the solar system to my sixth grade
students which will allow them to become more interested
and excited.” The PD that Barbara completed for
stamplevel recognition was mostly centered on using technology
in the classroom. In her initial interview, Barbara’s
emphasis on finding innovative teaching tools was
synonymous with using technology in the classroom. In the
end, Barbara completed five Solar System stamps.
Sally wanted to focus on increasing her personal
knowledge to “assist my students in understanding of how
the cycling of matter in and out of the atmosphere relates.”
Many other educators, like Sally, used their goal statements
to demonstrate an interest in helping their pupils to
improve. However, Sally’s goal was more specific with
regard to content and improving her knowledge. It is clear
to see that Sally’s learning goal was exactly what she
pursued in TLJ content. All of the PD that she received
recognition for was in the category of weather and climate,
which aligned with her goals. At the end of year one, Sally
completed six Weather &amp; Climate stamps and three
Weather &amp; Climate badges.
      </p>
      <p>During their post-interview, both Sally and Barbara
commented that they saw value in setting purpose
statements because it helped them think critically about the
PD they needed in order to meet their personal goals. By
examining Barbara and Sally’s goals, selections, and
completed PD, we found that their focus was narrow when
compared to other teachers that completed at least one
stamp. From these findings, we can tell that support may be
needed to help teachers in identifying focused and
manageable learning goals.</p>
    </sec>
    <sec id="sec-20">
      <title>5.2 Choosing a Stamp or a Badge</title>
      <p>
        Personalization was also clear when analyzing the topics
that learners selected. Our earlier work found that teachers
most often sought the entry-level stamp as
microcredential, rather than a badge [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]: the 36 participating
teachers earned 133 stamps (86.4%) and 21 badges (13.6%)
across the three STEM content areas. We posit that by
providing teachers the ability to make decisions about their
assessment (high or low levels of mastery) provided them
the flexibility to personalize their PD to align with their
existing and desired expertise teachers needed for
successful teaching. The total in Table 2 is compared to
Barbara and Sally’s experiences with TLJ and demonstrates
a wide discrepancy in selected activities to do and those
completed. While Barbara and Sally completed nearly as
many activities as they selected for their itinerary, this is
not the case with the overall 36 teachers. The full group
demonstrated that the teachers selected many more than
they were able to accomplish in the summer of year one.
This may provide additional reasoning for creating leveled
[
        <xref ref-type="bibr" rid="ref11">11</xref>
        ] badges. By offering lower-stakes or smaller
granularity badges, learners may be able to select and
complete more of the badges that they’ve identified as
relevant to their learning.
      </p>
      <p>Personalization was not just in the topic area but in the
approach to PD. Barbara and Sally each worked
exclusively on one topic. Barbara worked on solar system
activities and began by exploring PD related to a general
understanding of planets, next focused specifically on
Mercury for three activities, and then returned to more
general solar system PD again. Sally chose only weather
and climate activities. Her selection was similar to
Barbara’s where she would vary her content focus. Sally
chose PD activities with a fairly consistent alternating
pattern between weather and climate content. Sally reported
she was initially not enthusiastic about teaching weather
and climate science in class, but she felt strongly about
finding activities within the TLJ that would energize her
and support her to feel more prepared to work with her
middle school classes. Barbara also expressed interest in
finding solar system PD activities in order to help her
prepare for her lessons in the upcoming school year.</p>
    </sec>
    <sec id="sec-21">
      <title>5.3 Activity Logs</title>
      <p>To earn a badge or a stamp, teachers had to write and
submit an activity log. The teachers’ activity logs consisted
of their explanations of how, when, and where the TLJ
badging STEM materials will be used to enhance pupils’
learning in their university, school, or museum. For these
teachers, the TLJ content not only filled a gap in STEM
resources as discussed above, but TLJ activities were used
to transform current teaching practices. Teachers discussed
how the TLJ material could be used to meet specific needs
of their pupils. Nancy earned six Solar System stamps and
one Weather &amp; Climate stamp. In her activity logs, she
wrote about the unique learning needs of individual pupils
and used TLJ resources to help those diverse pupils enjoy
interactive activities. For example, Nancy commented,
“[TLJ] helped me absorb the information….If it was useful
for me, then it would be useful for learners in classroom
environments.” Nancy, like many other teachers in our
dataset, was not only looking for quality content in the
badging activities for her own learning, but in her activity
log, she carefully considered how the delivery and
activities of the STEM content would work in the diversity
of her class.</p>
      <p>Erin was one of the most robust TLJ users; she completed
eight Engineering stamps; four Engineering badges, two
Weather &amp; Climate stamps, one Weather &amp; Climate badge,
and one Solar System stamp. In her activity logs, Erin
described how she could supplement the TLJ materials to
bridge the gap for pupils who had little exposure to the
content or to challenge more advanced pupils. To earn her
seven stamps, Nancy wrote in her activity logs how she
would adapt the TLJ content for the younger elementary
pupils in her classroom. Specifically, Nancy developed
lesson plans that incorporated the detailed NASA images
and simulations in her teaching. Nancy also reflected on
how she would use the materials from the badging system
to engage her pupils more fully in the STEM content. She
wrote, “students who are not highly motivated in science or
mathematics and students who are not challenged enough
through the use of engineering processes would enjoy the
interactive activities if they are implemented and facilitated
effectively.”
Through the TLJ activity logs, the teachers often wrote
about the topic of inclusion and of a student-centered
approach. Zoe described herself as a learner who enjoys
hands-on and visually rich instruction in her logs. Zoe
completed two Solar System stamps. In her log, she wrote
that she liked “how all the activities presented are hands-on
and visual to reach a variety of learners. If the students are
able to see it and manipulate it they are more likely to learn
it.” Barbara wrote that an activity was just “okay” for her,
but then after trying to “put myself in my 6th grade
students’ shoes and see how they would respond,” she
concluded that with the help of some supplemental the
activity would be “a great listening activity.”
Lily used her logs to reflect on how she would use projects
and classroom discussions in her upcoming school year.
Lily wrote logs to earn one Solar System stamp, two
Engineering stamps, three Weather &amp; Climate stamps, and
one Weather &amp; Climate badge. She intended to use the
information that she learned within the badging system to
provide opportunities for her pupils to discuss in class other
topics, such as climate change and land formations.</p>
    </sec>
    <sec id="sec-22">
      <title>5.4 Mentor Feedback on Activity Logs</title>
      <p>In order for a teacher to receive recognition for completing
a PD activity, a reflective log was submitted for review.
These required logs for completed PD also provided an
opportunity to make professional learning an authentic
learning experience. Sally made use of her reflections as
write up for other colleagues in order to share the resources
she found. Barbara reiterated the value of the reflections as
a reminder for what worked and what did not for her class.
Both Sally and Barbara made use of the logs to make direct
applications to their own teaching.</p>
      <p>
        The NASA education experts within TLJ that acted as
mentors frequently provided feedback to learners related to
the submitted logs for the badging activities. This feedback
often included suggestions related to the topic, common
STEM misconceptions they or their pupils may face, and
pedagogical approaches appropriate to the STEM content
presented. Barbara described her experience with the
feedback as offering “really great suggestions.” This
dedicated support from these expert educators supports
TLJ’s effort to enhance the credibility of the badging
activities with experts employed [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ] with respect to the
evaluation of logs and the awarding of badges and stamps.

    </sec>
    <sec id="sec-23">
      <title>5.5 Collaboration during PD Activities and after PD Activities were Completed</title>
      <p>
        Discussions were supported through the use of TLJ
webinars, which allowed the teachers to communicate with
other teachers and with teacher educators. This
communication was short-duration (1–1.5 hours) and done
over an internal chat program that was available to all
participants. However, it still provided benefits for teachers
that did not know each other prior to the webinar. For
example, in her post-interview Barbara describes her
interest in having the opportunity to discuss what might
work in their classrooms as evidenced by forming teacher
cohorts in order to provide an on-going channel for the
exchange of dialogue and artifacts such as lesson plans,
student collected data, and feedback. Cohorts within TLJ
could provide teachers with long-term opportunities for
discussion and collaboration. Long-term benefits for
teachers could include a chance for sharing successes,
identifying ways to improve, and developing shared lesson
plans. Short discussions provided benefits for teachers as
well, such as learning how each teacher approached a
lesson differently, but could also lead into a longer term
engagement. For example, in one of her logs Erin writes
about attending an engineering webinar, describing how
each teacher took a turn in discussing the activity, and then
how she later connected with some of these teachers
through another online resource for STEM educators.
While the full TLJ analysis of the 36 teachers showed
evidence that all the teachers valued the collaboration.
When surveyed about future social and collaborative
functionality for TLJ, 67% of the survey participants —the
second most popular response—agreed with the statement:
“I would like to be part of a cohort of teachers similar to
me that I could work within online workshops and other
activities.” More specifically, the cases of Barbara and
Sally illustrate the nuance in the existing opportunities to
collaborate via synchronous or asynchronous conversations
with other teachers. For example, Sally stated that while
she did participate in discussions, she was equally happy
being an observer of the other teachers’ exchanges. When
asked about future collaborative opportunities, both
teachers wanted more opportunities to engage in
discussions like those in the webinars. Barbara further
elaborated that she would like to continue the PD activity
discussion later with others that completed the activity in
order to share what worked and did not work when trying
to implement the lesson. While the analysis of data only
demonstrates relatively short duration collaboration, future
iterations of TLJ would benefit from badges designed to
support opportunities for peer modeling similar to that
made available in the work of Ching and Hursh [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ].
The collaborative aspects of TLJ reached into the teachers’
work with their pupils. The teachers reported incorporating,
or the intention to incorporate, materials from the TLJ
badging activities in their classroom to support the
development of collaborative skills in their pupils or with
their peers. These collaborative aspects were reported to be
included within pupils’ group projects, classroom
discussions, and on the teachers’ websites for use with
pupils and parents. Erin, as a leader in her own STEM
school, needed enhanced PD that covered content beyond
the standard science curriculum, given the special emphasis
on STEM in her workplace. Erin wrote in her logs how the
TLJ materials were already successfully incorporated into
training that she facilitated for other teachers during the
summer that emphasized collaborative skills. In addition to
Erin, other teachers wrote in the activity logs that they
would share the resources from the TLJ activities with their
colleagues.
      </p>
      <p>
        While designed to support both asynchronous, independent
learners, as well as groups of learners, these findings
further support Hickey and colleagues’ recommendation to
promote collaboration [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]. Collaboration was an important
theme among the teachers’ logs. Teachers wrote about
collaborating with local universities (Lily and Erin), a
principal (Erin), and other teachers (Anne Marie). Teachers
appreciated the feedback provided in TLJ by their mentor,
and with this support, teachers felt confident enough to take
on larger projects like science fairs (Lily), science
academies, and leadership roles relating to their own
schools PD (Erin). As teachers engaged in a community of
learners, it was most often through professional learning
opportunities arranged with peers in their district or school
building, as exemplified by Erin’s experience.

    </sec>
    <sec id="sec-25">
      <title>Outside the Badging System</title>
      <p>The PD that TLJ provided allowed for personalization that
resulted in reports of relevance and authentic practice.
Teachers were given the opportunity to submit feedback for
each completed activity and among the 76 responses, 96%
either agreed or strongly agreed to the statement “this
activity is relevant to my teaching.” Across all the teachers’
responses to the post-survey, 93% agreed that the TLJ
experience influenced their teaching for the upcoming
school year. In addition to the PD content, the activities
were also structured to require a reflection where teachers
in some way consider how they might apply what they have
learned back to their classroom.</p>
      <p>
        Within the case study analysis, Sally explained she was
able to find relevance with TLJ by being able to “hunt and
choose” among all the PD activities to find what best meets
her needs as a middle school teacher. While Barbara shared
the resources she found with her partner teacher to make
use of them in their lesson plans. Since starting to share
these resources, Barbara moved closer to making her TLJ
experiences situated within her district’s teaching
community. In addition to engaging smaller professional
communities, such as the school and district level, the
teachers in our study contributed to an educator online
learning community that was supported by TLJ and can
help to promote exchange between teachers from all across
the country. Through itineraries and logs, teachers are able
to map their own learning trajectories [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ] of past and
future learning which may help learners to visualize their
badge experiences and learning over time.
      </p>
      <p>For the teachers in our study, the earning of the actual
stamps and badges was secondary to the learning of the
STEM content area. For example, Barbara and Sally
described the stamps and badges as “nice” but “not
necessary” respectively. These two teachers were interested
in the content for their own personal goals, as well as
professional goals. Barbara wrote: “the big value is in the
activities themselves.” This finding demonstrates that the
value of these awards of completion is currently not evident
to the general educational community. Both collegial and
competitive benefits can be gained from improving a
teacher’s ability to showcase their accomplishments and in
the future, researchers and educators working on badging
need to make the value of badging clearer to school
districts, employers, policymakers and other opinion
leaders. However, the overall opinion of badges and stamps
was favorable as evidenced in the post-survey (Figure 4).
When asked to select as many of the following forms or
recognition you would like to receive for recognition of
your work in TLJ, teachers ranked badges and stamps as
highly as continuing education credits (CEUs) and below
printable portfolios and letters of recognition. In this
regard, future redesigns of TLJ may include a portfolio
with stamps, badges, and details describing the learning
goals of the PD. Portfolios like this can then be shared with
colleagues, administrators, parents of the children in their
classroom, or even friends and family who are interested in
STEM topics.</p>

      <title>6. DISCUSSION</title>
      <p>
        This analysis focused on the experiences of 36 teachers in
TLJ in regard to how TLJ badges and badging system
served as a cultural tool to support STEM learning in
relation to dimensions of personalization, collaboration,
and authenticity (i.e., relevance). Our project was oriented
to understanding learners’ badge-earning trajectories as a
lens into (a) the refinement of mobile learning theory that
aims to support learners’ reflective activities and
selfexpressed goals and (b) the development of
technologyenhanced learning practice through the distillation of
design principles applicable to badge issuers in improving
their educational programming and instructional design
decisions. To reflect our goal, this final section is divided
into three parts. The first subsection reflects on how the
activities supported or did not support learners’ reflection
and personal or professional goals obtainment. The second
subsection considers methodological implications for
studying learning with and of badges. The final section

      <title>Personal and Professional Goals</title>
      <p>From our analysis of interviews, summative interviews, and
badging activity logs, TLJ teachers found themselves in
decision-maker roles to personalize their STEM learning.
TLJ teachers first selected their learning goals and then
they identified personally applicable badging activities that
they believed best met their own goals. By providing
options to the teachers, the TLJ educators explored STEM
content at depths and breadths that matched their
individualized expertise, teaching experience, and
classroom needs. For our interviews and activity logs, we
know that this is important to not only their professional
learning but to their personal satisfaction with the TLJ
badging program. All the teachers wrote that they found
benefits in making choices to personalize their STEM
learning. Many wrote or spoke in their interviews that they
found the direct application of TLJ materials to their
classrooms and customization of the activities through TLJ
logs meaningful parts of the badging experience. The
importance of making connections from the badging
materials to their own learning and that of their pupils was
especially compelling in the excerpts from Sally’s and
Barbara’s interviews and logs. Collaboration was a key
aspect of the TLJ badging system because the teachers
shared experiences and education resources with other TLJ
teachers, teachers in their educational institutions, and even
the pupils and parents that they served. The logs and
interview data showed that TLJ provided opportunities for
teacher dialog that was relevant to their work
environments. Importantly, our data showed that the
badging activities allowed the TLJ teachers to share lesson
plans in relation to how the engineering, solar system, and
weather and climate content could be made relevant to the
lives of youth.</p>

    </sec>
    <sec id="sec-30">
      <title>Badging Systems with Metadata</title>
      <p>
        As part of our research with badges [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ], we developed
techniques for studying the impact of the badging through
the data and metadata contained in the badging system
itself. Given that digital badging is an emerging technology
without many empirical guides to studying badging
impacts, an important outcome of our work for the field of
technology-enhanced learning is to consider which forms
of data were useful to our analysis. Most importantly, we
found that no one data source served our research needs.
The ability to triangulate the badging experience of learners
in TLJ with the multiple data sources (i.e., pre- and
postinterviews, activity surveys, summative survey, goal-setting
statements, and badging logs) helped to support how
teachers used badges for STEM learning and PD. We also
found that collecting data at the start, during, and at the end
of year one helped elucidate the learning journeys as
teachers’ experiences with badging grew over time.
Collecting activity logs and activity surveys immediately
after each activity was completed was especially important
to attending to any redesign work that was needed for year
two and beyond.
      </p>
      <p>We also found the following data was missing that would
have helped our work. During year one of TLJ, we did not
collect the feedback from the mentors. This could have
helped the research team to better understand how and if
teachers were taking this feedback into account in badges
completed afterward. Moreover, this study would also have
benefited from the collection of data related to
collaborative engagement between the learners and the
experts and among learners while engaging in more
synchronous webinar badge activities, including capturing
chat logs and other forms of communication between
teachers. This would have helped the research team to
explore how learners supported the learning of their peers
through a more in-depth focus on collaboration and the role
of conversations to support learning.</p>

      <title>6.3 Implications for Future Design Work</title>
      <p>While we had a relatively small dataset of 36 teachers, our
work is suggestive of several design principles for digital
badges that can be refined through future data collection
and analysis. First, the teachers in our full sample (and 11
focal teachers) personalized their badging experience in
two key ways: selecting specific badging activities and then
choosing an appropriate level of assessment (stamps,
badges, or both) for their own expertise, goals, and
classroom needs. This aspect of the design was highly
valued by our research participants across multiple data
sources. In order to support additional personalization in
future iterations, we will continue to use goal-setting
purpose statements in the initial goal-setting section of our
work as well as at least two levels of assessment. Our
findings from some teachers suggest that goal setting could
be improved by providing examples to help guide the initial
creation of goals that are attainable, specific, and focused
and possibly by encouraging teachers to rework their goal
statement after a certain number of badges were earned. As
shown in Table 2, the teachers selected many more
activities than they could have completed in the time that
they allotted for themselves over the summer. Also, the
teachers selected many more activities than they could have
completed in the time that they allotted for themselves over
the summer. To address this finding, rather than asking
learners to rework their goal-setting statements after a
certain number of badges are obtained, the system could be
designed to automatically send out reminders asking
learners to revisit their set goals at specific periods.
Given that many teachers, including Sally and Barbara,
expressed interest in collaborating with others as they
earned badges, more long-term collaborative opportunities
can be designed into the content in our next design
iteration. For instance, creating cohorts or other groupings
could provide people with the ability to discuss their
badging learning experiences. This cohort model would
allow learners to exchange information such as data
collected by their classroom and pedagogical approaches
that have worked in a particular lesson. These cohorts could
be set at the start of the experience or after so many badges
are earned to create groupings of people with similar
STEM content experiences. These collaborations might
also be supported by using the TLJ system to allow
teachers to create their own groupings or to match
geographically located teachers together.</p>
      <p>Finally, the logs were identified by most teachers as helpful
to connect the STEM learning within the badging system to
their educational institution. This suggests there may be
benefits from incorporating even more supportive
structures into the badging system related to the activity
logging required to earn a stamp or badge. For example,
within the collaborative PD webinars, reflective questions
were posed to all the teachers to support their engagement
in the PD activities. Given the success and the popularity of
these prompts, this structure could be repeated by TLJ in
other aspects of the design. For instance, specific questions
could be asked as part of the reflection logs that were
required to be submitted to earn a stamp. More clearly
incorporating specific prompts and supporting framework
into the structure of each badge or stamp activity, we posit,
could help to support teachers to reflect on certain aspects
of their learning or future use of what they have learned
thus making their experience more authentic. Being able to
focus on a few parts of their learning may help to provide
an even more favorable experience with required
reflections by all teachers.</p>

      <title>7. CONCLUSION</title>
      <p>In this paper, we explored the utility of combining
perspectives on technology-enhanced learning, cultural
tools, and mobile learning frameworks to design and study
digital badges with K-12 teachers. From our analysis of the
experiences of the teachers that participated in the project’s
first year, we suggest that future badging systems collect
multiple forms of feedback (or data) from participants to
support meaningful understanding of the badging system.
We also found that including choices in the types of
content, the types of assessment, and the pathway sought
was important to our participants in terms of
acknowledging their expertise, interests, and classroom
needs. These finding support the following design
principles: (a) two levels of assessment (i.e., stamps and
badges) can support personalized learning, (b) mastery of
learning can be demonstrated and assessed through
reflective logs completed to earn a badge or stamp, (c)
collaboration during and after badging activities (with
colleagues within the badging system and outside of it) can
provide value to the learners, and (d) establishment of
relevance of badging experiences to professional practice
can support the application of content outside the badging
system after the recognitions are earned.</p>
