Design-based research (DBR)
“The challenge of design-based research is in flexibly
developing research trajectories that meet our dual
goals of refining locally valuable innovations and
developing more globally usable knowledge for the
field.”
(Design-based research collective, 2002, Educational
Researcher)
“The design-science paradigm seeks to extend boundaries
of human and organizational capabilities by creating
new and innovative artefacts”
(Hevner et. al., 2009), MIS Quarterly)

Design Study Approach in Year 1
MATURE - Continuous Social Learning in Knowledge Networks

Design Studies
 8 critical experiments in design
• explored key aspects that needed to be validated prior to
embarking on a full-scale draft requirements specification
 Characteristics
• Exploratory not confirmatory
• Focussed and time limited
• Based on existing tools with limited further developments
• Incorporated both conceptual and software development foci
• Application partner involvement (consortium/associate)
o Inspired by real user needs
o Developed in close interaction with end user representatives
o Collected feedback on the end result
• Evaluated
o Cover key aspects and phases of knowledge maturing?

Design Studies in the project organization
MATURE - Continuous Social Learning in Knowledge Networks 6 6

Evaluation and coordination: DS Grids
 DS grids linked design activities to conceptions and
activities consistent with knowledge maturing (KM),
through 12 questions
• What aspects? (conceptual, technical, user)
• Specified whether PLME, OLME, both
 Provided an aggregated picture of design activities
 KM: phases covered? commonalities? gaps? candidates
for integration?
…advance organisers to get design teams thinking in
terms of KM, ‘user requirements in context’

On to Year 2:
from Use Cases to Demonstrators

Prioritizing use cases:
where should focus on first?
 Useful and user-driven:
Solving a real problem of application partners
 Focussed:
Adressing a key knowledge maturing issue,
yielding a distinctive solution
 Relevant to TEL research:
Adressing a key challenge for technology-enhanced
learning research (using the PROLEARN TEL priorities)
 Feasible:
Feasible within the project timeframe and resource
constraints

How did we approach it?
 Collecting priorities from application partners and
scientific partners
 Aggregating high priority use cases into groups
 Development of demonstrator definitions
• Scenario
• Relevance for knowledge maturing
• Benefit for application partners
• Research challenges
 Cross-checking demonstrator definitions with
TEL priorities from the PROLEARN Roadmap
 Concrete planning (time, resources, involvement)

Demonstrators
 Demonstrators covering groups of use cases
• Implementing a coherent scenario
• Feasible within one year
• Can be evaluated within the next year
• Clearly illustrate the added value of MATURE in an example
 Will evolve into the “MATURE solution”
(OLME/PLME/Maturing Services)
• built on a shared infrastructure
• Key architectural issues will be solved across demonstrators
 The other use cases will be added or redefined at a
later stage

Summary
 Design-based research as an underlying methodology
 First year activities were 8 focused design studies
• early and critical experiments in design that informed further
design activities prior to Use Case process (year 1)
 Use case definition as a moderated bottom-up process
 4 Demonstrators covering groups of use cases
with high priority and a coherent theme for year 2
• will constitute the 1st Prototype after year 2
