Experimental designs in the social sciences have received increasing attention due to their power to produce causal inferences. Nevertheless, experimental research faces limitations, including limited external validity and unrealistic treatments. We propose combining qualitative fieldwork and experimental design iteratively--moving back-and-forth…

This study examined the roles of gender and STEM major status as predictors of performance in formulating a research question and designing experiment among 70 undergraduate Taiwanese college students participating in inquiry-based learning (IBL). Student participants in this study were involved in discrepant demonstrations of scientific events…

This article presents an innovative technique for teaching the principles of experimental design in a way that is entertaining and engaging for students. Following a lecture on experimental design, students participate in an experiment in which the teacher uses a funny segment from a movie to test the influence of implicit social norms. Randomly…

In this article, we test an alternative approach to creating a counterfactual basis for estimating individual and average treatment effects. Instead of using control/comparison groups or before-measures, the so-called Counterfactual as Self-Estimated by Program Participants (CSEPP) relies on program participants' self-estimations of their own…

This paper reviews literature on the rationale, challenges, and recommendations for choosing a nonequivalent comparison (NEC) group design when evaluating intervention effects. After reviewing frequently addressed threats to validity, the paper describes recommendations for strengthening the research design and how the recommendations were…

Using dictator games in experimental analysis, this lesson report demonstrates the process and results of a postgraduate class project in which university students were instructed to scientifically investigate and explore one of German society's most hotly-contested issues: the level of discriminatory tendencies of non-Muslims towards Muslims. The…

Background: Coaches developing young talent in team sports must maximise practice and learning of essential game skills and accurately and continuously assess the performance and potential of each player. Relative age effects highlight an erroneous process of initial and on-going player assessment, based largely on subjective opinions of game…

This article examines secondary students' design of experiments after engagement in an innovative and inquiry-oriented module on heat transfer. The module consists of an integration of hands-on experiments, simulated experiments and microscopic model simulations, includes a structured series of guided investigative tasks and was implemented for a…

This article explores the practical relevance of pragmatism as a research paradigm through the example of a piece of pragmatic research that not only used both quantitative and qualitative research methods but also exploited the inherent duality of the data analyzed. Thus, the article aims to make the case that pragmatism as a research paradigm…

We believe a lack of transparency undermines both the credibility of, and interest in, stated choice studies among policy makers. Unlike articles reporting the results of contingent valuation studies, papers in the stated choice literature rarely present simple tabulations of raw response data (that is, a table or graph showing the percentage of…

Describes the history of the random experiment in the Home Office in the United Kingdom and demonstrates that research and the conduct of research is not an altogether rational process and that fashion, personality, and politics play a role in research policy and methodology choice. (SLD)

Examined the shift in the educational-research paradigm in Finland as seen in 335 doctoral dissertations. Early in the century, educational history was the dominant topic, but by the 1950s the experimental paradigm took over. By the 1980s, factor analysis was a very common research method. In the 1990s, qualitative analyses account for one-third…
