This report reviews a study of the effects of "Saxon Algebra 1/2" on the mathematics achievement of 8th-grade students and a comparison of textbook content between the intervention and comparison curricula (Crawford & Raia, 1986). Crawford and Raia conducted three analyses with different subsets of the overall sample, but only one analysis is reviewed in this study report. In this matched sample, math achievement of 8th-grade students participating in the "Saxon Algebra 1/2" (intervention) classrooms was compared to math achievement of 8th-grade students participating in Scott-Foresman Mathematics (comparison) classrooms. This report summarizes the study and reviews its strengths and weaknesses.
