Design Experiments in Educational Research
TLDR
Design experiments have both a pragmatic bent and a theoretical orientation as mentioned in this paper, developing domain-specific theories by systematically studying those forms of learning and the means of supporting them, and the authors clarify what is involved in preparing for and carrying out a design experiment, and conduct a retrospective analysis of the extensive, longitudinal data sets generated during an experiment.Abstract:
In this article, the authors first indicate the range of purposes and the variety of settings in which design experiments have been conducted and then delineate five crosscutting features that collectively differentiate design experiments from other methodologies. Design experiments have both a pragmatic bent—“engineering” particular forms of learning—and a theoretical orientation—developing domain-specific theories by systematically studying those forms of learning and the means of supporting them. The authors clarify what is involved in preparing for and carrying out a design experiment, and in conducting a retrospective analysis of the extensive, longitudinal data sets generated during an experiment. Logistical issues, issues of measure, the importance of working through the data systematically, and the need to be explicit about the criteria for making inferences are discussed.read more

Inquiry pedagogy to promote emerging proportional reasoning in primary students
TL;DR: Proportional reasoning as the capacity to compare situations in relative (multiplicative) rather than absolute (additive) terms is an important outcome of primary school mathematics as discussed by the authors, and this thinking can influence their capacity for proportional reasoning in later years.

The role of theory in learning technology evaluation research
TL;DR: This paper attempts a fundamental analysis of the nature of research into e-learning and the role that theory plays in this, and identifies various desired research outcomes which are appropriate at each stage of the e- learning lifecycle.

Design-based research for LIS
Leanne Bowler,Andrew Large +1 more
TL;DR: Design-based research is a methodology emerging from the field of education that may hold potential for research in library and information science (LIS) and is also of interest to professionals concerned with “evidence-based practice.”
