The researchers adopted the multi-stage but simple random sampling technique to draw the sample. The subjects were 882 SSII students from the secondary schools in Owerri Education Zone of Imo State. The study is prediction-design research of correlational type. This paper investigated self-regulated learning skills as a predictor of students’ achievement in mathematics based on ability level. It can be concluded that Powtoon animation learning media is feasible and effective to be used in improving the understanding of mathematical concepts. The resulting product is effective in increasing the understanding of mathematical concepts, as evidenced by the average pretest score of 43,44, an increase in the posttest of 84,27, and the N-Gain value of 0,72 in the high category. The effectiveness of using the product can be seen from the results of the comparison of the students' average pretest and posttest scores. Based on the results of the product assessment by all validators who stated that it was very feasible, the Powtoon animation learning media developed had meet the criteria for use for students. The percentage results of product assessment by media experts are 96% in the very feasible category, the percentage result of product assessment by material experts is 92% in the very feasible category, and the percentage result of product assessment by 10 small group students is 94% in the very feasible category. The subjects of this study were students of class VIII-2 MTsS Syamsuddhuha (junior high religious school). The development model used is the ADDIE model. The purpose of this development research is to determine the feasibility and effectiveness of using Powtoon animation learning media for flat-sided geometry.

This showed that there was a significant effect of using the REACT strategy assisted by GeoGebra software on students' mathematical representation ability. The results of the data analysis of the posttest score tested using the t-test, the sig value was obtained. The data obtained from the posttest results were analyzed by data normality test and data homogeneity test, then hypotheses were tested using a t-test to see the effect of REACT strategy assisted by GeoGebra software on students' mathematical representation ability. Four posttest questions were given to 25 students of Class VIII A and 25 students of Class VIII B at SMP Negeri Arun Lhokseumawe (public middle school). The design used in this study was The Nonequivalent Posttest Only Control Group Design. This study was quasi-experimental with a quantitative approach.
