The study of the effectiveness of problem-based learning on academic performance, motivational beliefs and self-regulated learning strategies in gifted high school girls. 86 98 142 FA Journal Article 2015 07 11 The objective of this study was to examine the effectiveness of problem based learning which is one of the student-centered teaching methods on enhancing academic performance and motivation of high school talented students. It was a quasi-experimental design. Nonequivalent pretest-posttest control-group design was used in order to check the role of PBL on academic performance and to investigate the effect of PBL on motivational beliefs and self-regulated learning strategies, nonequivalent posttest-only design was used. The instruments were two equivalent forms of second grade high school chemistry lessons and motivational beliefs and self-regulated learning strategies questionnaire (Pintrich and De Groot, 1990).<br />The results of analysis of covariance (ANCOVA) showed that there were not any significant differences in academic performance between control group and experimental group. Furthermore, the results of multivariate analysis of variance (MANOVA) showed that PBL could decrease test anxiety and could increase intrinsic value. ،The results were discussed in the paper.
