Abstract

This study aims to analyze the improvement of students' mathematical problem-solving abilities through the implementation of the AIR learning model with the RME approach on the topic of flat sided geometric material in Grade VIII at SMP Negeri 45 Batam. This research is a quasi-experimental type of research, with a pretest-posttest control group design. The sample was selected using probability sampling with a cluster random sampling method, so that two sample classes were obtained, VIII C as the experimental class and VIII F as the control class. The test instrument in the form of essay questions to measure students' mathematical problem solving abilities on flat-sided geometric material was used to collect research data. The research results showed that the average improvement in mathematical problem-solving abilities for the experimental class was 0.42, while for the control class it was 0.31. From the Independent t-test of N-Gain, the Sig. value was 0.044, it can be concluded that the average mathematical problem solving ability of students through the application of the AIR learning model with the RME approach is higher than the average mathematical problem solving ability of students using conventional learning models.

Abstract

This study aims to determine the effect of differentiated learning with a flipped classroom model assisted by the S.id platform on students' mathematics learning outcomes. This research used a quantitative approach with a one-group pretest-posttest design. The population of this study comprised all seventh-grade students at SMP Negeri 1 Bintan. Purposive sampling technique was used based on the assessment of expert teachers, namely the seventh-grade mathematics teachers at SMP Negeri 1 Bintan. Data collection techniques used were tests and observations. The instruments used were the main instruments consisting of test sheets and observation sheets, as well as supporting instruments consisting of learning modules, differentiated learning materials, and question sheets. The data analyzed was quantitative data using the Paired-Sample T-test. The results showed that the average pretest and posttest scores were 43.1 and 76.2, respectively, with a significance value (2-tailed) of 0.000. The results revealed a significant difference between the pretest and posttest scores, indicating the effectiveness of differentiated learning with a flipped classroom model assisted by the s.id platform on students' mathematics learning outcomes. This, it can be concluded that there is an effect of differentiated learning with a flipped classroom model assisted by the S.id platform on students' mathematics learning outcomes.
