Results of modifying mastery learning strategy to two diagnostic cycles with high school chemistry students (N=156) indicated that achievement of mastery learning students was significantly greater than that on nonmastery learning students. Attitudes toward science/science instruction were not significantly different but were positive in both…

This study explored the effects of a modified mastery learning strategy as well as locus of control and aptitude on achievement, attitudes, and on-task behavior of high school chemistry students (N=156). Mastery learning in this study was modified to limit diagnosis and remediation to two cycles. Three treatment groups were included: (1) contrast…

Bloom has argued that most students, not just a few, should be able to do top quality school work if given appropriate instruction. Mastery learning, which includes frequent diagnostic testing followed by remedial instruction, has been proposed as an effective strategy for increasing pupil achievement. In this study, teachers used a mastery…
