This paper focuses on the trade-offs that lie at the intersection of methodological requirements for causal effect studies and policies that affect how and to what extent schools engage in such studies. More specifically, current federal funding priorities encourage large-scale randomized studies of interventions in authentic settings. At the same…

In the wake of an increasing political commitment to evidence-based decision making and evidence-based educational reform that emerged with the No Child Left Behind effort, the question of what counts as evidence has become increasingly important in the field of science education. In current public discussions, academics, politicians, and other…

Develops a way to conceptualize the complementarity of quantitative and qualitative research in science education, demonstrating through analysis of examples that qualitative and quantitative research reports follow the same pattern of argument, although the metaphysical roots behind their methodologies are obviously different. (Author/SK)

Basic characteristics of survey as a research study are discussed. Issues associated with survey research, potential uses of survey research as a strategy in science education, and potential problems jeopardizing survey studies are also discussed. (JN)

Examined three methods which can be used to pool single-item-per-subject data collected in intensive time-series studies, determining if method of pooling has an effect on subsequent data analysis. Methods examined were based on simple averaging, difficulty weightings of averages, and the application of the Rasch logistic model. (JM)

To determine whether practice was consistent with recommended research methods, this study examined 130 studies reported over a 5-year period in the "Journal of Research in Science Teaching." Results show that appropriate generalizations beyond the confines of the reported studies may be impossible in most (64%) of the studies.…

Contains a debate on research design and methodology considerations of the study. (CP)

Examined is how research informs and influences the practice of science education. Discussed are past focuses on treatments, present focuses on students' ideas, and developing styles of research. (YP)

The use of the expert-novice technique in science education is examined critically. Discussed are four techniques including their methodological limitations. Improvements and alternatives in experimental design are suggested. (Author/CW)

Presents data which leads to the construction of a response to the question of how different phases of the learning cycle influence physics students' content achievement and attitudes. Discusses the importance of the learning cycle in science instruction and the strength of using contrasting techniques (qualitative and quantitative) in research.…

Criticizes the Mitchell and Lawson (1988) report from the viewpoint of individual interview method. Provides Lawson's reply to the comment by showing differences in research philosophy and methods. (YP)
