In this study, we conducted peer instruction (PI) activities to promote student participation in the learning process and test the hypothesis that PI improves student achievement. Two ninth-grade classes were randomly assigned as treatment and control groups. Pre-test and post-test data were obtained for measuring mathematics achievement in trigonometry. Data were analyzed using analysis of covariance procedures with an alpha significance level of 0.05. Results indicated no significant effects of peer instruction on achievement. This study implies that more robust studies are needed to reveal the real effect of PI.
Science motivation scale is a valid and reliable tool used to determine students' motivation in learning science courses. In the study, science learning motivations of students studying at Kazakhstan and Russian Universities were compared. In addition, it was also examined whether the science motivation scores of the students changed according to the demographic variables. The science motivation scale was used as a measurement tool. For statistical analysis, t-test and ANOVA from Bayesian statistics were used. As a results, the data supported the students' motivation levels a) at a high level, where they differed from the countries they studied at b) at a moderate level, where they did not differ by gender c) at a moderate level, where there was a difference in the total score according to the age group, d) at a moderate level, where there was no differentiation by departments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
