Possible causes for the discrepancy between the ABT report on the national Project Follow Through and the Saint Louis, Missouri program were discussed: (1) ABT data were positively biased because of non-random, differential attrition from the program and control groups; (2) positive ABT data were due to use of a particular cohort group; or (3)…

Presents a summary of nine research reports from a National Educational Computing Conference research workshop whose purpose was to bring together researchers who have been conducting gender-related research in computer science education. Three subgroups discussed the issues of exposure, attraction, and retention of women to computer science. (MDH)

This study of student teachers' beliefs was conducted to track changes in their beliefs about teaching and examine the role of academic and practical experiences in modifying these beliefs. The primary focus of this paper is the evolution of methodology, with extracts from three case studies presented to illustrate the direction the research is…

Challenges some assumptions and methods used in nutrition education practice and research, offers alternative viewpoints for studying and intervening in certain nutrition behaviors, and discusses programmatic and methodological issues which have limited the application of existing theories and data in research and practice of nutrition education.…
