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) MATURE - Continuous Social Learning in Knowledge Networks 3 3

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’ 7 7

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 MATURE - Continuous Social Learning in Knowledge Networks 14 14

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) MATURE - Continuous Social Learning in Knowledge Networks 15 15

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 MATURE - Continuous Social Learning in Knowledge Networks 16 16

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 MATURE - Continuous Social Learning in Knowledge Networks 18 18
