ABSTRACT
This chapter deals with the evaluation in design research that drives intervention development while at the same time seeking to inform an external scientific community of the results and their possible utility for others. This kind of evaluation is conscious, systematic, and formalized. The chapter describes the main activities and outputs of the evaluation and reflection sub-cycle, which has its own logical chain of reasoning, before discussing how the detective and inventor mindsets can be of value. During the evaluation and reflection phase, design ideas and prototype solutions are empirically investigated, and the findings are reflected upon, with the aim of refining understanding about if, how, and why intervention features work. Seven methods are among the most common for use during the evaluation and reflection phase: interviews; focus groups; observations; questionnaires/checklists; pre/post tests; logs/journals; and document analysis. The evaluation may show that teachers highly value the way the tool helps them structure formative assessments.
