Abstract. Kelluwen is a learning community composed of teachers, students
and researchers who are devoted to assessing and promoting ICT-mediated
learning strategies, focused on improving students’ socio-communicative skills.
Kelluwen has a Web platform (http://app.kelluwen.cl) that supports b-learning
activities allowing teachers to create, use and share instructional design leverag-
ing Web 2.0 tools. This paper presents the development of an e-portfolio to be
included in the Kelluwen platform, which aims at improving the support for
awareness and reflection processes of students and teachers during their didactic
experiences. Considering the requirements of the learning community, the e-
portfolio is divided into four sections: Works, Evaluations, Statistics and
Work's Gallery. The tool developed is evaluated in a pilot experience and we
conclude that it enriches the learning processes by facilitating their comprehen-
sive evaluation.
Keywords: e-portfolio; web 2.0, awareness and reflection.
1 Introduction
Kelluwen is a learning community the purpose of which is to improve the communi-
cation skills of elementary and high-school students introducing the use of collabora-
tive web tools and social networks in learning processes, combining online and face-
to-face (b-learning) didactic activities [16]. Under this context, the Kelluwen team has
worked closely with teachers and education researchers in the development of rele-
vant didactic designs. A didactic design (DD) is a type of instructional design based
on social web tools that allows students to work collaboratively, post the outcomes of
their learning and get feedback [4]. In addition, the Kelluwen web platform includes
several communication and content management tools to support the didactic experi-
ences of students and teachers when they run a DD. ([2], [11] and [17]). Kelluwen
team proposes a comprehensive evaluation strategy of socio-communicative skills
that involves awareness and reflection about the learning process by students and
teachers. From the perspective of evaluator agents, the evaluation strategy includes
the application of the following types of self-evaluation guidelines: metacognitive, co-
41
E-portfolio for Awareness and Reflection in a Blended Learning Environment - ARTEL16
evaluative (joint evaluation) and hetero-evaluative (teacher to students) for the collab-
orative work. However, before this work, only peer-assessment was supported in the
platform, while the rest of the evaluative processes were performed with guidelines
available as files or hardcopy.
This work seeks to enrich the web platform, considering the peer-revision
module with new features that support the application of different evaluative strate-
gies, including views to facilitate the awareness and reflection of both students and
their teachers about the learning process. The new tool being developed is an e-
portfolio, which in addition to supporting a comprehensive evaluation process, pro-
vides both teachers and students with a space to manage all the products developed in
a didactic experience.
The question that guides this research is the following: Can the proposed e-
portfolio tool make a contribution to students’ and teachers’ awareness and reflection
processes about their didactic experience?

2.1 Evaluation Typologies
There are several ways of classifying evaluations. The most common classifications
consider aspects such as functionality, timing or who evaluates [5]. This work consid-
ers the typology that classifies evaluation by its agents, i.e. based on the individuals
who evaluate in each case. According to this criterion, the main types of evaluations
are self-evaluation, co-evaluation and hetero-evaluation. To complement these types
of evaluations, in Kelluwen we have also adopted i) Product co-evaluation: an evalu-
ation performed by a group of students of a product generated by a second group of
students. This type of evaluation is critical in the didactic activities proposed in
Kelluwen [18], ii) Eco-evaluation: This evaluation is the one performed by a person
of the environment in which the activity or phenomenon to be evaluated took place
[10]. In Kelluwen, this is the evaluation of the learning experience by the student.
2.2 Best Practices in the Use of E-Portfolios
The concept of e-portfolio has several directions. While some articles define e-
portfolio as a platform for the organization of student-created artifacts [2], others
conceive it as an evaluation tool ([8] and [9]). In spite of these differences, several
best practices can be recognized in the e-portfolio literature, as presented below.
Reflection mechanism introduced in the e-portfolio: A common factor is the use of
the e-portfolio to improve learning by reflection. For instance, in [7] students are pro-
vided a space in their e-portfolio to write their reflections. Included are reflections on
learning objectives, learning outcomes, attitude facing learning, peer performance and
their evaluations. In [6], the student must develop a reflection on each artifact posted
in his/her e-portfolio. In addition, there is a final evaluation where the student must
reflect on the entire process. Several e-portfolios include reflection as an evaluation
42
E-portfolio for Awareness and Reflection in a Blended Learning Environment - ARTEL16
object. For instance, in [9] there is a student self-evaluation instance to generate her
self-reflection about his/her artifacts and opinions in the support platform forum. The
number of reflections about other works and the time students devote to them is also
evaluated.
Register of evaluations as part of the e-portfolio: A common trend is observed in
terms of registering evaluations in the same e-portfolio. In [7] there is a section devot-
ed to evaluations where students sign into “E-portfolio evaluation” which provides
online forms to perform self-evaluations and co-evaluations. Similarly, the teacher
can perform the hetero-evaluation in the same tool. Additionally, [6] provides tools to
evaluate the reflections by students using the “Chinese Word Segmentation System”
which classifies the type of reflection made.
Sharing e-portfolio artifacts: E-portfolios encourage the sharing of works and pro-
vide tools to collect critical feedback from other students. In [13] there is an area for
presenting the best projects where students can easily access their classmates’ work.
This area is called “Gallery” and it allows students to search works based on a set of
criteria, including valuation, date, visits, student, course and semester.
Finally we remark that we use the concept of e-portfolio in the sense of an space to
organize the processes and outcomes of learning activities during a limited period of
time and not in sense of life-long e-portfolio.
2.3 Awareness and Reflection in b-learning Environments
[14] performs a systematic revision related to awareness and reflection processes in b-
learning environments, stressing that most studies focus on the monitoring and visual-
ization –by teachers– of their students’ learning process, with little research focused
on supporting students in the awareness and reflection of their learning process, nor
on providing teachers with information about their own practice. Within this small set
of studies there is [12], which presents an extension of the WebLearn platform, the
design of which is focused on providing students with support for their awareness and
reflection processes and on providing teachers with information to review their own
teaching practice.
3 Kelluwen E-Portfolio
Considering the main best practices in the use of e-portfolios found in the literature
and the requirements of the community of teachers who have participated in
Kelluwen, four modules were developed in the e-portfolio: Works, Evaluations, Sta-
tistics and Work Gallery. A stable version of the platform that includes the Portfolio is
found in http://app.kelluwen.cl/, accessible through a simple register. Below is a de-
scription of the Evaluation and Statistic modules, given their relevance in the aware-
ness and reflection about the learning process of students and teachers.
43
E-portfolio for Awareness and Reflection in a Blended Learning Environment - ARTEL16
3.1 Evaluations
In this section of the e-portfolio, the Student View allows access to the different types
of evaluations, depending on the activity that is being performed. Fig. 1 shows the
module in which the evaluation displayed are team performance and work assess-
ments. A simple diagram represents the evaluations with arrows between the student
and her team mates. Each evaluation has a guideline, for instance, the team perfor-
mance evaluation includes questions like: “She was responsible in fulfilling tasks”,
“She helped his groupmates when they needed” or “She contributed to the group
learning process”. In the case of work assessments, the questions are more specific to
the subject area: “It is included in the slideshow a reflection about the conflicts expe-
rienced during the study period” or “A previous organization is observed in carrying
out their slideshow”. In the experience assessment, there are more general questions:
“The learning experience managed to satisfy a present need in your schooling” or
“You think that criticism of the twin classrooms serve you to guide your learning”.
Each guideline includes a space to make comments or explain the achievement levels
assigned. The role of this open comment is to promote the students’ reflection pro-
cess.
3.2 Statistics
This section deals with statistics or analytics of the results of the evaluation processes,
considering visualizations that summarize the evaluations that each student or group
gets from the different stakeholders involved, using two types of charts: i) histograms
that show the frequency of each achievement level considering aggregated criteria of
the evaluation guidelines; ii) radial chart that represent the most frequent achievement
level for each disaggregated criterion. Additionally, different comparisons are made
based on the type of evaluation: when dealing with performance assessments, self and
co-evaluations are compared, while in the case of product evaluations, peer evalua-
tions are compared with the evaluation performed by the teacher (see Fig. 2).When
evaluating the experience, the evaluation of all students are compared.
4 Results of the Pilot Survey
During 2015, a pilot experience in the use of the Kelluwen Portfolio was conducted
in two ninth grade twin classes at the Laico High School (classroom 1) and Martin
Luther King High School (classroom 2), both in the city of Valdivia. The DD applied
was “Building a Slide Show about the 2nd Half of the Twentieth Century” in the suject
of History, Geography and Social Sciences. A total of 60 students, 31 from classroom
1 and 29 from classroom 2, arranged in nine groups per classroom, participated in the
experience that took place during October 2015.

Fig. 1. Student View of Evaluation Section with Team Performance and Work Assessments.
Both teachers developed all the activities with their students, including all the pro-
posed evaluation instances. All the groups posted works (68 in classroom 1 and 167 in
classroom 2). During the experience, three activities of the Design were related to the
evaluation, as follows: i) group co-evaluation, where 21 students in classroom 1
(68%) and 23 in classroom 2 (79%) completed the evaluation of their group mates;
product co-evaluation where the 18 groups were assigned to reviewers between clas-
ses (twin classes) and completed the evaluation; iii) eco-evaluation, where nine stu-
dents from classroom 1 (29%) and 25 from classroom 2 (86%) completed the evalua-
tion of the didactic experience.
4.1 Usability Study.
A survey was applied among the 60 students to capture their perception about Portfo-
lio’s usability, adapted from the proposal in [1] designed to obtain a usability index of
software applications. For classroom 1, the average obtained is 71.086, while for
classroom 2, it is 74.553. Hence, both cases suggest that the Portfolio’s usability is
within the best acceptability range; i.e., students assess the tool as good according to
the interpretation of the index in [1].

4.2 Perception Survey about the Portfolio’s Usefulness.
A qualitative analysis of the Portfolio was performed by means of a survey developed
by the research team and applied to all the students during the pilot experience. The
survey looked into the students’ perception about the implications of the Portfolio on
the learning and evaluation processes, and also of the tool’s usefulness. The survey is
organized in three parts. The first part focuses on the Works module; the second on
the Evaluations module; and the third part contains questions about the Statistics and
Gallery modules. The questions are statements that express a positive or negative
valuation of the e-portfolio’s functions. There are four levels of responses: strongly
disagree (MD), slightly disagree (LD), slightly agree (LA) and strongly agree (MA).
The neutral level was discarded to force an expression of positive or negative opinion.
The results of the perception survey show that for all the positive statements regarding
the usefulness of the Portfolio, most students either strongly or slightly agreed, with
percentages above 70% between both options. Regarding the negative statements
about the usefulness of the Portfolio, students’ responses were more heterogeneous
without a clear trend unlike the case of positive statements. The distribution of this
survey’s answers is shown in detail in the Appendix.
Fig. 3 shows the results of the survey questions that more directly address –in the
opinion of students– the impacts of the Portfolio on the reflection about their learning
process. Fig. 3(a) shows the results of a question that inquiries whether the evalua-
tions performed made them reflect on their own learning process; student responses
are somewhat heterogeneous, with an agreement of 50% for students in classroom 1
and 75% in classroom 2. Fig. 3(b) shows the results of a question referred to the val-
46
E-portfolio for Awareness and Reflection in a Blended Learning Environment - ARTEL16
orization of the evaluations’ graphic summaries in promoting reflections about team-
work. In this case, 82.5% of classroom 1 students strongly or slightly agreed, while
this was true for 85.7% of classroom 2 students.
4.3 Discussion Groups
Two discussion focus groups were conducted made up by students from both class-
rooms in the pilot experience. The purpose of this activity is to understand the mean-
ings attributed by students to their participation in the experience, considering the
valorization of the e-portfolio as an environment to support the reflection and motiva-
tion of their learning processes. The classroom 1 group was formed by six students.
This focus group suggests: i) Broad approval to the e-portfolio:
(a) (b)
Fig. 3. Both classroom students’ perceptions regarding the question about their reflection pro-
cess in (a) the use of the Evaluations section and (b) the use of the Portfolio’s Statistics section.
The main attributes mentioned are: ease of use; interaction with students from other
schools; all works are available in the same place; and that it can be used both at
school and home. ii) Group co-evaluation was a matter of debate as there was a lack
of consensus on its proper use by classmates. Classroom 2 group was made up by five
students. The following can be summarized from the conversation: i) All of them
stated to like the portfolio, that it was something new and fun to use, ii) Most thought
that the evaluations were easy to use and some said that they would like to add com-
ments per criterion in addition to the achievement level. One student mentioned that
this way, the teachers could also explain their evaluations.
5 Discussion and Conclusions.
The results of the usability study show that students qualified the e-portfolio in the
acceptable category, with a usability index of 71.1 in classroom 1 and of 74.6 in class-
room 2; both values are within the “good” usability range. This outcome is consistent
47
E-portfolio for Awareness and Reflection in a Blended Learning Environment - ARTEL16
with the results collected with other evaluation tools, where students suggest several
elements to improve the Portfolio’s usability.
The results of the perception survey show that most students positively assess the
Portfolio as a tool that supports work posting, comprehensive learning evaluation and
the emergence of moments of reflection and awareness in the context of the didactic
experience developed.
Discussion groups confirmed the outcomes of the prior surveys and complemented
them by specifically arranging the critiques to the tool being proposed. One element
worth highlighting is the diversity of perceptions around the co-evaluation process of
the team’s performance; while it was extremely well assessed by student from class-
room 2 as a reflection driver for the development of teamwork, the students from
classroom 1 considered it an uncomfortable and unfair process. On this regard, it
should be mentioned that the two classrooms involved in the pilot experience are part
of two different school situations which could probably explain such diverging opin-
ions.
Based on the outcomes emerged, we can conclude that our e-portfolio meets the
role of contributing to the awareness and reflection of students about their learning
process, particularly concerning the development of teamwork skills, as well as in
feedback processes of works posted in the platform. Another relevant aspect is the
role of teachers in the design of didactic experiences, which in this case were directly
related to the development of different evaluation guidelines which made it possible
for such guidelines to be extremely well contextualized and therefore, to be perceived
as easy to be developed by students. On the other hand, the Portfolio can also support
teachers when monitoring the work of students, enabling them to compare their own
perceptions of the work performed by students regarding the evaluations they get in
the peer review.
Most of the findings or confirmations that the e- portfolio is useful to support the
process of awareness and reflection of students are transferable to other learning
communities and are related to the focus on a comprehensive assessment process ,
which not only emphasizes the products if not the underlying processes.
Future work is expected to complement the feedback provided to students and
teachers with analytics of the activity in the portfolio of the participants of the didactic
experience, such as those proposed in [15]. We will test these learning analytics in the
Kelluwen platform with didactical designs concerning critical reading and citizenship.
