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

5 5

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 needso Developed in close interaction with end user representativeso Collected feedback on the end result

• Evaluatedo Cover key aspects and phases of knowledge maturing?

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’

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
