To illustrate a system for analyzing research reports, four published evaluations of the Biological Sciences Curriculum Study (BSCS) program were analyzed in terms of problem raised, previous work cited, objectives stated, hypotheses formulated, assumptions made, population studied, sample drawn, instruments used, design examined, procedure followed, safeguards taken, observations recorded, findings assembled, statistics interpreted, interpretations discussed, conclusions reached, limitations recognized, further work projected, improvements suggested and clarity of report. The analysis is reported as a chart with each aspect of each report graded from A to E according to the author's judgment of the strength of the study in that area. The author concludes that the case for BSCS has yet to be proved. (EB)
