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

A comparison of single and multiple strategy instruction on third-grade students' mathematical problem solving.
TL;DR: In this article, a study was conducted to assess the differential effects of a single strategy (schema-based instruction) versus multiple strategies (general strategy instruction, GSI) in promoting mathematical problem solving and mathematics achievement as well as to examine the influence of word problem-solving instruction on the development of computational skills.

Problem solving in the United States, 1970-2008: research and theory, practice and politics
TL;DR: Problem solving was a major focus of mathematics education research in the US from the mid-1970s though the late 1980s as mentioned in this paper, and that work continues to evolve in important ways.

Design approaches in technology-enhanced learning
Yishay Mor,Niall Winters +1 more
TL;DR: This work provides a motivation and rationale for design approaches for learning technologies that draws upon Simon's seminal proposition of design science and argues that a patterns approach has the potential to address many of the critical challenges faced by learning technologists.
