Describes a technique that can be used to construct variables from clinical interviews that can be used in quantitative analyses. The technique involves the representation of each proposition a student uses in terms of a standard set of underlying predicates, concepts, and relationships among concepts. (JN)

Outlines a narrative method for the study of classrooms. The main feature of the method is the reconstruction of classroom meaning in terms of narrative unities in the lives of classroom participants. The work's theoretical character is introduced by comparison and contrast with Schon's "The Reflective Practitioner: How Professionals Think in…

Identifies promising areas of aptitude-treatment interaction research (ATI), including research related to general ability, anxiety, prior achievement, and achievement motivation. Also provides general methodological ATI guidelines for science educators. (JN)

Offers a critique on some of the papers on computers in science teaching that were presented at the 1985 National Association for Research in Science Teaching meeting. Implications for the conduct of research on computers in science learning are also suggested. (JN)

The substance of a commentary (SE 539 500) is a criticism of the over-generalizations by authors of computer-assisted instruction papers at the 1985 annual meeting of the National Association for Research in Science Teaching. This reaction attempts to examine the validity of the criticisms made in the commentary. (JN)

This article offers five research criteria and their rationale to help researchers avoid problems and to help them improve research. Improving research should improve the quality of science teaching. The treatment of causal hypotheses is stressed. (Author/CW)

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)

Describes methods designed to add new studies to published meta-analysis results, focusing on a procedure using Bayesian analysis and showing how new findings complement previous meta-analysis and extend its conclusions. Also considers how studies are to be weighted, which variables are to be examined, and how often meta-analyses are to be…

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)

Several studies of the validity of the intensive time-series design have revealed a post-intervention increase in the level of achievement data (the "momentum effect"). Reports on the development and use of a technique to study the effect as it is observed in several data sets on the learning of plate tectonics. (Author/JN)

In this project, a resynthesis of the research dealing with student performance in new science curricula was conducted using refined statistical procedures. Results generally supported earlier meta-analysis studies. (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.…

Described is a cost-effectiveness analysis applied to the question of the probable impact of 69 actions advocated for improving science education. The major objectives and the 11 categories of interventions are discussed in regard to effective schools and implementing educational change. (KR)

Calls for differentiating between three kinds of studies of students' conceptions in science, namely descriptive studies, explanatory studies, and studies attempting to foster conceptual change. Cites the literature about student perceptions and science instruction. (TW)

Summarizes the results of a preferred method of study questionnaire in which college students explained how they approached reading a new textbook. Reports that women showed a significant preference for adopting a single method of study. Indicates that there was no discernable relationship between study strategies and college level. (CW)
