Abstract: Students need to learn ‘21
st
century skills’. However, teaching materials for this are scarce. Moreover 21
st
century teaching is adaptive and teachers often need to design teaching materials themselves. Design Based
Learning (DBL) is a promising approach for teaching 21
st
century skills. This paper describes the development
of a tool to support primary school teachers in creating 21
st
century skills teaching materials, DBL materials
in particular. After defining initial requirements, the study moves on as ‘design research’ comprising iterative
design rounds. The resulting tool largely fulfils the stakeholders and teachers expectations, supports teachers
in creating 21
st
century education and activates teacher reflection, even though it does not yet produce
classroom ready material. To be effective in promoting DBL, it is necessary to further elaborate the concept
of DBL and to supplement it with an explicit pedagogical strategy and concrete assessment procedures.
1 INTRODUCTION
As in many other countries Dutch education is
changing to meet future challenges. So called 21
st
century skills are identified as critically important
(Cogan & Derricott, 2014; Rotherham & Willingham,
2010). Primary education has to change, but this is
challenging for most teachers. In particular since 21
st
century teaching typically requires students to work
in groups and learn from open-ended authentic
projects with relevance for the students and their local
environment. For this type of education, only few
teaching materials are available. The materials need
to be tailored to the students’ needs and the situation.
This demand that teachers create their own materials.
Teachers need support for developing such
teaching materials. Firstly to provide them with
‘pedagogical models’ and examples that underpin 21
st
century teaching, a way of teaching sometimes new
to them. Secondly, to support and guide them in the
process of designing education. This support can
(best) be delivered online.
This paper describes the creation of an online tool
that supports primary school teachers as reflective
practitioners in designing 21
st
century teaching. It
uses the ‘pedagogical model’ of Design Based
Learning (DBL).
2 BACKGROUND
Many Dutch teachers are convinced of the need for
changes in their teaching approach and are motivated
to implement these changes. Apart from challenges
such as taking a more coaching role in classroom, a
key challenge is the lack of teaching materials. This
requires design tools that also store the lessons
designed to help teachers and to allow them to
effectively profit from earlier initiatives. Moreover,
the changing practice is such that teachers must
design their own student tailored - materials, putting
an even greater demand on their competencies.
Finally, the examination syllabus has not (yet) been
fully adapted to the renewal, and teachers have to
combine the new challenges with the classical
curricular aims (‘kerndoelen’), that concern
knowledge and (mainly) instrumental skills.
Teachers meet various challenges in designing
21
st
century learning activities. Firstly, teachers have
worries about learning goals and assessment. For
example: how to make sure that the projects
effectively address the various 21
st
century skills?
How to make sure that all of the obligatory ‘classical
aims’ such as mathematics or language skills are
well-covered? How to efficiently move forward to

create learning activities that have the right balance
between ‘classical aims’ and 21
st
century skills?
Secondly, teachers lack the skills and experience of
educational designers. In educational literature, a
variety of educational frameworks for developing
classroom materials is available. For example, the
curricular spider-web schema by Van den Akker,
Gravemeijer, McKenney, and Nieveen (2006). Such
frameworks can stimulate and structure educational
design. However, teachers are usually not acquainted
with these, and these resources should be made
available to the teachers in an easy-to-use way.
Thirdly, teachers may have no clear view of what
the new education would look like. Coherent and
challenging projects are needed and Design Based
Learning (DBL) has been put forward as a model.
2.1 Design Based Learning
Design Based Learning (Bekker, Bakker, Douma,
Van Der Poel, & Scheltenaar, 2015) is a teaching
approach in which students learn by collaboratively
creating designing solutions to open (societal)
challenges. DBL allows students to work on authentic
challenges. This often leads to intrinsic motivation
and deeper insights into how the learned knowledge
and skills can be applied in practice.
DBL is a form of inductive learning(Prince &
Felder, 2006) with the potential to provoke a major
shift in educational practice and constitute a new
pedagogy which might transform education (Sharples
et al., 2016). DBL can promote design thinking which
directly contributes to 21
st
century skills. It is
generally defined as an analytic and creative process
that challenges the learner to experiment, to create
and prototype models, gather feedback, and to
redesign” (Razzouk & Shute, 2012, p. 330).
In this study a more precise description of the
characteristics of DBL is needed for developing and
evaluating the design tool. Gomez Puente, Van Eijck,
and Jochems (2013) have described properties of
DBL through an extensive literature review and a
subsequent empirical validation in higher education.
This framework was used in earlier studies to define
characteristics of DBL in primary and secondary
education (Bekker et al., 2015; Scheltenaar et al.,
2015). From this a set of DBL-characteristics is
defined for use in this study (Table 1).
2.2 Online Teacher Support Systems
Online support of teachers designing education has
been extensively studied (McKenney, Nieveen, &
Van den Akker, 2002). In this, a principal dilemma is
the trade-off between flexibility on one hand, and
structuring, channelling, guiding and scaffolding
design choices (Pérez et al., 2017) on the other. It is
key to find an effective balance that limits design-
space in support of teachers yet respects teachers
professional autonomy en encourages their
reflectiveness.
Designing learning tasks comprises an overwhelming
number of interrelated choices leading to massive
cognitive (over)load for novices (Sweller, Ayres, &
Kalyuga, 2011). For teachers that are novices or
inexperienced in the type of teaching to be developed,
the time needed for designing and preparing a lesson
may be over 10 times the duration of the lesson itself.
Novice teachers and teachers confronted with an
innovation new to them lack insights underpinning
the innovation that could guide design decisions (see
Vos, Taconis, Jochems, & Pilot, 2011). Clearly tools
and exemplars are needed. Furthermore, teachers
should have access to the rationale behind the
innovation. This could provide criteria for
considering various design options and can support
them in making design choices.
To support designing teachers, it is crucial to
reduce the ‘design space’. A first component is
structuring the design process. This takes away much
of the interrelatedness of the various design choices
which is difficult to understand for the novice
teacher/designer. Structuring can be less strict for
more proficient teachers/designers that already can
understand the ‘when and why’ of various choices
(Silver, 1991). A second component is to make design
options transparent, and to reduce their number
through pre-selection.
To make websites that present complex processes
or situations in an intuitive and predictable way, these
should be structured according to users’ mental
model(s) of these processes or situations. An example
is the lay-out of the railway station manager’s
dashboard. Hence the online design tool should be
organized according to the teachers' perception of the
process of ‘planning education’. This model can be
found by examining how a representative groups of
teachers views this (Bernard, 2000; Roth, Schmutz,
Pauwels, Bargas-Avila, & Opwis, 2009).
Structuring the design process and pre-selecting
design options alone would ‘robotize’ the teachers’

society)

design process, frustrate teachers as autonomous
professionals and hinder their development as
reflective practitioners (Schon, 1984). Hence the
online support system should give room for teachers’
professional autonomy and professional decisions.
Moreover, it should stimulate reflection while
designing education. Even more so for designing
DBL since reflection is in the heart of the design
process itself (Bekker et al., 2015).
Hence, structuring and pre-selection of design
choices should be minimized, but must also be
rigorous enough to prevent cognitive overload.
Scaffolding and guidance to support teacher in taking
the remaining design-decisions is key. Jackson,
Krajcik, and Soloway (1998) have developed such an
adaptive strategy: Guided Learner Adaptable
Scaffolding (GLAS). They distinguish 3 types of
scaffolds: supportive (e.g. advise, highlighting
options), reflective (e.g. clarifying alternatives and
criteria, asking for deliberations), intrinsic (e.g.
relating to the design process as a whole).
3 AIM
The central Aim of the study is to create a tool
supporting primary school teachers in creating DBL
with a productive balance between structuring,
guiding and reflecting, that also is well
implementable. It should also promote DBL and
design thinking in education.
3.1 Research Questions
The central question in this project is: Can an online
tool be developed that supports primary school
teachers creating 21st century lessons that include
‘classical learning goals’ using DBL?
Specific sub-questions are:
a) Does the tool support teachers in designing and
in reflecting during design?
b) Is the tool well adopted and implementable?
c) Does the tool effectively promote DBL as a
pedagogical model?
4 RESEARCH/DESIGN METHOD
The projects was set-up as an educational design
research project. Such projects move forward in
rounds in which design and testing/evaluation
alternate (Van den Akker et al., 2006). Evaluation in
often carried out using a multi method approach in
which the results of e.g. material-analysis, classroom
observations and interview or questionnaires are
combined (Meijer, Verloop, & Beijaard, 2002).
The various data sources principally address the
education to be evaluated at different curriculum
levels (Goodlad, 1979). Interviews with teachers for
example - address the ‘perceived curriculum’,
whereas classroom observations address the
‘observed curriculum’. Hence, the data from the
various sources supplement each other. Alignment
and discrepancies point out the level to which the
‘intended curriculum’ was actually transformed in
classroom reality. These ‘levels of curriculum are
also found in the evaluation scheme (Table 2).

4.1 Evaluation Scheme
Data collection and analysis was organized according
to the evaluation scheme shown in Table 2. Five
‘main variables’ are evaluated on 4 of the Goodlad -
curriculum levels: Theoretical, Perceived, Material
and Experienced curriculum. For each level particular
data-sources are available (bottom row in Table 2).
When used, the cell of the scheme fill, and
comparison of the findings in one row over various
columns reveals how the intentions underpinning the
tool worked through in e.g. teacher perceptions,
teaching materials created and/or classroom reality.
The categories reflect the studies research
questions. The first category is fundamental to
evaluate the general effects off the tool on the created
education and concern general aspects of learning
environments according to (Van Gelder et al., 1973).
The second employs the work of (Doyle & Ponder,
1977) on adoption of educational innovations and
implementability. Key factors considered here are:
understandability, usefulness, easy to use’, and
congruence with the teachers convictions.
The third category ensures the evaluation of the
way the tool addresses the various DBL components
(see Table 1). The fourth category focusses on teacher
support and the stimulation of reflection. The fifth
category concerns the educational goals.
4.2 Setting and Respondents
Data were collected from expert panels, stake-holder
panels, user sessions, user interviews, analysis of the
tool, analysis of the classroom material designed, and
classroom observations. Five teachers and four
stakeholders participated in the project. They were all
from the PlatOOlab (2017) group of schools. This is
a regional network of primary school collaborating in
modernizing education in close cooperation with
educational institutes and the city administration.
Expert panels comprised 12 experts with expertise in
educational design, educational research and/or
teacher training. The main researcher worked in close
cooperation with the design team, but was not a
member of it.
5 STUDY DESCRIPTION
5.1 Initial Specifications and Tool
At the start of project a preliminary tool by
Van der Sanden (2016) was used as input for two
stakeholder meetings with PlatOOlab school-leaders
and leading teachers. Also a panel of 6 experts was
asked to give feedback on the preliminary tool.
Finally, existing tool-kits for supporting teachers in
teaching ‘design’ were evaluated (e.g. IDEO, 2013).
This led to a list of must-haves, should-haves and
could-haves. Implementation of particularly the
must-haves led to the initial tool used in the first
round.
The initial tool (Figure 1) provides support for
handling the openness of the design activities, 2)
linking a design problem/challenge to a theme and
learning goals, 3) building up a set of learning
activities linked to concrete learning goals, 4)
selecting design methods related to design phases, 5)
selecting collaboration forms for the different
learning activities.

5.2 First Design Round
In the first round five teachers were interviewed about
the tool, and three teachers were observed while
working with the tool. Teaching materials developed
were evaluated, and 4 lessons previously designed
using the tool were observed in classroom. Both the
teachers and the students were observed.
5.2.1 Results
Overall, the tool is used as intended. While using the
tool the teachers struggle with the workflow which is
sometimes ‘a bit illogical’ or unclear. The workflow
in the tool also differs from what these proficient
teachers usually do when designing education, and
comprises typical design-activities which they are
still unacquainted with.
Table 3 shows the results in the format of the
general evaluation scheme, which we will discuss
row by row. The first row shows that some general
aspects of learning activities (e.g. homework,
assessment) lack in the tool. The teachers were able
to compensate for this and arrive at complete
educational arrangements nevertheless; but this
critically depends on their (apparently sufficient)
proficiency as designers.
The second row shows that the initial tool scores
high on congruence, but low on usefulness and
understandability which is in line with the findings
in the first row. The third row shows that the tool only
partly succeeds in making clear the concept DBL on
a theoretical level. This appears echoed in the ‘P-
column’ where the concept is absent, and the ‘E-
column’ where the key DBL-concept of ‘design
specifications’ is removed during the lessons in
classroom immediately after a brief introduction.
Apparently the tool did not clearly convey that this
concept is key to DBL.
The finding in the fourth row shows that the tool
is effective in guiding the teachers. No signs of
cognitive overload (e.g. confusion) were observed.
Finally, row 5 indicates that the ‘classical learning
aims’ apparently get lost during the design of DBL
learning activities.
5.2.2 Adaptations
In round 2 it was concluded that the structure of the
tool should be made more clear and should primary
reflect the teacher mental model of ‘lesson planning’
thus including for example homework and test.
The guiding-strategy apparently worked but
could still be improved after the removal of
incoherencies in the support of the first phase of
educational design. The previously existing design
skeleton comprising 3 phases: Meta description
(level, subject, theme, central-question etc.),
Choosing matching activities, Elaborating chosen
activities was implemented more rigorously.
Teachers can however leap forward, backward,
upwards and downwards while using the tool.
This firm skeleton allowed for a more
systematical implementation of the key elements of
DBL, for a better pre-selection of e.g. design
activities on the basis of element in the meta-
description, and for making connections between
classical learning goals and design-activities. Effort
was made to have the tool produce classroom-ready
products wherever possible.

5.2.3 Second Design Round
Due to the overhauling of the skeleton the second
version of the tool had to be completely rebuild in
another platform (Bakker, Bekker, & Taconis, 2017).
The new tool provides a better structure for the
teachers to decide on various elements of the lessons
to be developed, such as learning goals, educational
activity, length and mapping to design phases. The
tool takes them through a process of first deciding on
the global theme of the design activity, the intended
students, and the deliverables (steps one and two in
Figure 2). It then helps them to decide on how many
lessons to design, the linkage of the lessons to what
design activities, and choosing the design methods
that will be incorporated in the lessons (step 3 in
Figure 2).
Research in the second design round comprised
an expert review by (8) educational experts. Also the
improved tool was used by 4 teachers with a
researcher present. The design product resulting from
these sessions was analysed. Teachers-users and
stakeholders were interviewed. Unfortunately no
classroom use was possible due to logistical issues.
5.2.4 Results
The general picture is that the teachers-users are very
happy with the new tool. Those who have used the
initial version agreed that the revised tool is much
better structured, more informative, and more useful.
Table 4 shows the results in more detail. The first two
rows show that the tool now is a more clear, complete
and usable design support tool, that comprises all
aspects of and components of lessons to be planned.
The clear skeleton contributes to this. The tool also is
adequate in stimulating informed reflective design
decisions (row four).
However (row three) shows that the concept of DBL
still stays implicit. Users primarily value the tool as
an instrument for designing 21
st
century education in
a structured and reflective way. Besides this, the
second version of the tool did not succeed in
connecting 21
st
century aims and classical learning
aims to the DBL learning tasks designed.

6 CONCLUSION & DISCUSSION
Teachers and stakeholders value the design tool as an
instrument for designing 21
st
century education in a
structured way that also stimulates reflection. The
tool appears to be successful in this. However, it was
not found to be effective in promoting DBL.
Besides this, it remains unclear what exactly are
the learning effects of the DBL education that was
designed using the tool. Moreover, the tool can
clearly be improved in connecting specific ‘21
st
century learning goals’ and ‘classical learning goals’
to the DBL education designed. Two things seem
critical to make further improvements.
Firstly, the concept of DBL needs to be
supplemented with a pedagogical strategy that
describes the particular cognitive demands of the
design activities. Thus allowing to link these to skills
and knowledge needed to complete these. For this the
‘levels of inquiry’ by Ireland, Watters, Lunn
Brownlee, and Lupton (2014) may be used. This
would also allow for a better underpinning of the pre-
selection of design options presented in step 3 on the
basis of the ‘global decision’ made in step 1 and 2.
Secondly, assessment should get more attention
in future projects. Assessing of 21st-century
competencies is beyond the capabilities of most
traditional assessment formats (e.g., multiple-choice
test, self-report survey) (Razzouk & Shute, 2012, p.
330). As students work on their tasks, evidence can
be collected to evaluate their performance. But
teachers need support in this. The design tool should
preferably offer assessment formats that teachers can
use to create adequate assessments as an integrated
part of their DBL.
