Teacher Reports on Opportunity to Learn: Analyses of the 1993 California Learning Assessment System (CLAS)

Abstract

The California Learning Assessment System 1993 OTL Study allowed examination of the extent to which California public school mathematics teachers had been exposed to the practices consistent with those advocated in the California Curriculum Frameworks; the extent to which those teachers implemented these practices in their classrooms; and their impact on student performance in mathematics. The findings support the conclusion that curriculum and instruction that require higher level skills benefit students’ achievements. The data are the best available measures of California students’ learning of higher level skills, and provide consistent information for discussion and debate among educators about reform strategies.
