        <p>This paper proposes providing teachers with real-time accurate and pedagogically-relevant information to assist students in the development of 21st Century skills, across subject areas, using a variety of technologies and data sources. We suggest that, while allowing students to practice skills such as meeting facilitation, recording activities both directly and indirectly (student and peer reporting) will likely be a useful step in supporting students in their acquisition of such skills, while helping teachers guide development in their students through visualisations of their students' competencies.</p>

      <title>1 Introduction</title>
      <p>
        With the development of technology, it is necessary to consider how to support
students in their acquisition of 21st Century skills that will remain important in their
future; and to help teachers in their understanding or monitoring of students'
competencies, to enable them to better support their students' development. As an example
to span many subject areas, and incorporating 21st Century skills, we use the case of
student meetings. In principle these may take place face-to-face or online (e.g.
through web conferences or virtual worlds), and may or may not be supported by
specific meeting-facilitation technology (e.g. [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]).
      </p>
      <p>
        To support student skill development, teachers need access to data about their
competencies related to meeting planning, facilitation and outcomes. We provide this
in the Next-TELL project [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ] through student self- and peer-evaluations, and some
simple automated methods. This information forms part of the ‘learner model’, which
is provided visually to users, as proposed to be useful for teaching analytics [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ].
      </p>
      <p>
        We consider this to be a contribution to the challenges of ‘classroom
orchestration’ [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ]. Because it is a challenging task for a teacher to micro-manage group work
(with or without ICT) in a classroom with many students, software such as LAMS
(http://www.lamsfoundation.org/index.htm) has been developed to mitigate teachers’
cognitive load. In our approach, we aim to go beyond activity tracing (e.g. as
implemented with LAMS) by providing the teacher with visual information on students’
on-going learning on the competency level. Our approach also makes intentionally
more use of the students themselves as a resource for managing collaboration: by
putting a few students in the role of meeting facilitators, the teacher has fewer activity
management tasks to deal with and can concentrate on the overall classroom process,
rather than individual groups. By the same token, students are provided with authentic
opportunities to practice preparing and running on-line and face-to-face meetings, a
competency that is valuable both inside and outside schools.

      <p>Meeting Facilitation: A 21st Century Competency
Next-TELL considers three areas with reference to student-led meetings: planning
meetings; facilitating meetings; and documentation and communication of outcomes.
Each contains competencies represented in the learner model.</p>
      <p>
        The meeting process begins when an individual determines that a meeting is
required. One approach is a short yes/no ‘Should You Meet?’ checklist that can be used
for the identification of whether a meeting is necessary. For example, from
Francisco’s 8 item checklist: “Can you state the purpose of your meeting?”; “Do you have
the information you need to meet productively?” [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ]. Seibold further emphasises the
importance of identifying the specific purpose(s) of the meeting and delineating a
range of goals, to create the basic structure of the meeting [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ].
      </p>
      <p>
        A crucial step is to decide on the group composition for the meeting, to ensure that
all those affected, are represented [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ]. The tasks involved – including allocation of
roles and responsibilities – can be seen to form their own competency. In addition, all
members should be briefed on the points through an agenda, allowing individual
feedback prior to the meeting [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ]. The importance of group participation before the
meeting starts has also been highlighted, with a series of steps to improve
preparations before a meeting [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ]. This includes introducing complex issues at one meeting
and deferring discussion and questions for the next meeting; and the importance of
supplying written materials to participants in sufficient time prior to the meeting.
Participants should then read the material in advance, and perhaps have discussions
beforehand. Updating the agenda may result before a meeting [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ].
      </p>
      <p>
        It is suggested that an agenda should comprise three basic points: (i) the topics to
be discussed; (ii) the desired outcomes for each topic; (iii) processes needed to
achieve the desired outcomes [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. A variety of activities may be used in a meeting
which can be teamed with relevant level of involvement and time estimates in order to
specify the processes needed to achieve the desired outcomes. For clarity, desired
outcomes should be split into: the overall goal for the topic (what final result should
be achieved to complete the topic); and the meeting goal (what narrowly defined,
specific objective should be achieved for the topic at an upcoming meeting). These
goals do not necessarily have to be written in the agenda, but should be explicitly
stated during the course of the meeting [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ].
      </p>
      <p>
        Once the composition of the meeting has been decided, all appropriate group roles
should be delineated, responsibilities assigned and authority delegated where
necessary [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ]. It is suggested that at least two key roles of chair and secretary are necessary
in a meeting scenario [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ].
      </p>
      <p>
        To conduct a meeting in a meaningful way, it is necessary to balance creative and
critical thinking to productively support discussion and decisions [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ]. A facilitator
might use different types of intervention strategy if problems develop during a
meeting, for example: interpretation (shifting focus to the process, describing, inviting
discussion); direct action (interrupting meeting flow e.g. preventing interruption,
encouraging an individual) [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ].
      </p>
      <p>
        A meeting facilitator may effectively set the frame by describing: the task, the
outcome, the process, the rationale for the process, and the expected amount of time
required [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. Data resulting from group discussion or brainstorming may need to be
sorted using pre-defined criteria or creating categories, and the list may need to be
reduced through prioritising items.
      </p>
      <p>
        A meeting exit survey may be used to evaluate a meeting, for example: "How well
did we use the time allotted?", "How well thought-out were our decisions?" [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ]. Exit
survey questions can also address the skills of individual participants, such as "How
effective was the facilitator?" Indeed, questions similar to these have been used in
consultancy, in relation to evaluating the cost-effectiveness of meetings, such as: “The
meeting leader…runs meetings effectively”, “…listens carefully and actively”,
“…creates an environment where people are comfortable disagreeing” [
        <xref ref-type="bibr" rid="ref12">12</xref>
        ].
      </p>
      <p>
        While a meeting must be documented by capturing minutes and noting actions [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ],
this need for a record is often overlooked by students and, indeed, some textbooks do
not adequately cover all types of minutes in different settings [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ]. Thus, it is
particularly important for teachers to ensure students’ awareness of this requirement.
      </p>
      <p>
        Different technologies can provide different levels of system support to meeting
facilitation, e.g. from complete automation with no facilitator function, to simply
providing support for recording and reporting information [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ]. As Next-TELL is
designed for use in a range of subjects and settings, we concentrate on generic tasks.
This makes it particularly difficult to rely on detailed automation, hence the focus on
self- and peer-evaluation of meetings, in addition to simple automated measures, in
our approach to providing competency data in easy-to-use visual form, for teachers.
      </p>

      <title>3 Information for Teachers</title>
      <p>
        As stated in the Introduction, visualisations of students’ competencies in the form of
their learner model, are made available to teachers. Such ‘open learner models’
(OLM) may be visualised in a variety of ways (see [
        <xref ref-type="bibr" rid="ref14">14</xref>
        ]), and our current work is
building on the already common use of skill meters and smilies for younger users in
OLMs [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ], and developing state-of-the-art visualisations in the form of zoomable
treemaps and word clouds. The data in the learner model, as described above, comes
from some simple automated methods and student self- and peer-evaluations.
      </p>
      <p>In order to provide teachers with information on students’ competency
development in an automated manner, we provide students with a tool to plan their meeting
facilitation, and compare the meeting as planned with the meeting as conducted.
Planning a meeting consists of sequencing a number of group activities, which are
represented as meetlets. Meetlets combine the description of a series of steps (e.g. the
steps necessary to have a group perform a brainstorming activity) with a specification
of the tools and artifacts with which to conduct the activity. For instance, for a
brainstorming activity this could be a (collaboratively edited) Google Spreadsheet
document. Meetlets also contain information about how to evaluate the success of the
activity; e.g. in a brainstorming meetlet, this could be the number of ideas generated.
This is used to update the competency model of the facilitator and/or group members.</p>
      <p>Figure 1 depicts how information in the meetlet structure is used to drive a
specific meeting activity and to appraise/assess an activity. For the case considered here, the
meeting is conducted online. The descriptions of the sub-steps of an activity (for
instance, for a brainstorming activity this may include eliciting and combining
individual ideas) are interpreted by an Activity Stepper that guides the team members
through these steps, and then rules describing how the resulting artefacts (e.g.,
individual and collective idea lists) are to be appraised, are applied to the artefacts. This
artifact appraisal information is then used to update the learner model.</p>
      <p>We are considering simple appraisal rules that build on information directly
available in the artefacts. For example, for brainstorming,the number of individual ideas,
collective ideas, and the ratio between them, can be used to formulate appraisal rules.
More advanced rules could calculate the semantic overlap between ideas generated
individually and those proposed as a group solution, but are at present not
implemented. Our focus is currently on how to represent knowledge that is typically formulated
by teachers in rubrics in a way that can (in principle) be interpreted by machines.</p>
      <p>Manual input to the learner model may come from peers and the students
themselves, provided as follows, on a scale of 1 (strongly disagree) to 5 (strongly agree),
using the example of self-assessment by the meeting facilitator:
• I created an agenda
• I correctly allocated roles and responsibilities in the agenda
• I distributed the agenda in time for other participants to feed back before meeting
• Before the meeting I updated the agenda based on comments, as necessary
• I set the frame before each task (introduced task; clear outcome; process;
rationale; duration)
•
•
•
•
•</p>
      <p>I organised the meeting well
I made decisions after full analysis of all factors
I communicated the next steps and action plan effectively in the meeting
I assigned all tasks and actions to the right people, with clear follow-up deadlines
I reviewed the next steps and action plan at the end of the meeting</p>
      <p>
        The automatically calculated and student-provided appraisal data is brought
together in a (currently simple) quantitative learner model, which in turn is available to
the teacher (and usually also to students). Figure 2 shows excerpts for some of the
meeting competencies (upper – skill meters; lower left – word cloud (under
development); lower right – the reverse of lower left (i.e. competencies not yet demonstrated)
(under development). These displays can be used on-the-spot by teachers to provide
feedback to students, and to offer feedforward (guidance) as to which meeting
facilitation competencies to develop further. (While these representations are simple, for
immediate teacher reaction, more detailed information including evidence is also
possible [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ].) The granularity of display can be determined by the teacher (e.g.
“creating an agenda” could be further split into Kaner’s three points: topics to be
discussed; desired outcomes for each topic; processes necessary to achieve the outcomes
[
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. Teachers can use the visualisation(s) that best fit their purpose or preferences at
the time. For example, for a quick, on-the-spot decision about where a group needs
help, “setting the frame” clearly stands out as needing improvement on the lower right
of Figure 2. In contrast, the lower left of Figure 2 indicates that a meeting is probably
already well-planned, and perhaps the next phase should now be considered. The skill
meters (top of Figure 2) provide a more organised, quick visual context. They can
also display competencies from different areas (here Communication in English for
Norwegian speakers) - one way to practise English is through discussion, in meetings.
While open learner models have somewhat of a tradition in intelligent tutoring
systems, they may also meet the need for providing teachers with accurate and
pedagogically relevant information in real-time, when built on top of other educational
software. 21st Century “skills” is a particularly interesting case, because these skills do
not fit into just one teaching area (e.g. maths, science, language), but are ‘horizontal’
in nature. Hence, opportunities to learn and practise the skills required to develop the
competencies should be provided across classrooms, teachers, and school years. The
combination of an OLM with an infrastructure for recording learning-related activities
both directly (e.g. with Google Doc APIs) and indirectly (e.g. through student and
peer reporting) may prove a practical step to support students in learning and
practicing horizontal skills, and to support teachers in monitoring and guiding such learning.
