<![CDATA[This study was motivated by the low mathematical problem-solving ability of high school students. The purpose of this research was to determine the differences in mathematical problem-solving ability between students who received instruction through the Realistic Mathematics Education (RME) approach and those who experienced conventional learning in Grade XII Phase F of SMAN 2 Lubuk Sikaping, Pasaman Regency. The research employed an experimental method with a Control Group Posttest Only design. The population consisted of all Grade XII Phase F students in the 2025/2026 academic year. Samples were selected using random sampling, resulting in Grade XII F 8 as the experimental class and Grade XII F 7 as the control class. The research instrument was a problem-solving test in essay form, based on Polya’s problem-solving steps, which had been validated and showed a reliability coefficient of 0.855. Data analysis was carried out using a one-tailed t-test at a 5% significance level. The results indicated that the mathematical problem-solving ability of students taught with the RME approach was significantly higher than that of students taught through conventional learning. This finding suggests that RME provides contextual learning experiences, encourages active participation, and fosters critical, analytical, and creative thinking skills in solving mathematical problems. Therefore, RME can be recommended as an alternative instructional strategy to enhance the quality of mathematics teaching and learning in secondary schools.]]>

<![CDATA[Student learning independence is still lacking and student learning outcomes are still low is the background of this research. This study aims to determine the effect of students' mathematics learning independence after applying the Think Pair Share type cooperative learning model in class X SMKN 1 Ranah Ampek Hulu, Pesisir Selatan Regency. This study uses the One Shot Case Study research design. The data analysis technique used simple linear regression analysis. The questionnaire score regression coefficient (b) is 0.823 with a significant level of 0.05. Because the regression coefficient (b) is positive (+). So there is a positive influence between independent learning (X) on learning outcomes (Y). The closeness of the linear relationship between X and Y can be seen from the correlation coefficient r = 0.135 which means it is close to 0, so the linear relationship between X and Y is weak. The conclusion is that independent learning has an effect on student mathematics learning outcomes by using cooperative learning type Think Pair Share.]]>

<![CDATA[The development of 21st-century skills, particularly collaboration and critical thinking, has become a central objective in contemporary mathematics education. The Realistic Mathematics Education (RME) approach is considered a promising intellectual strategy for supporting these competencies through contextual problem-solving activities and structured social interactions. However, emperiecal evidence on the simultaneous contribution on both critical thinking and collaborative skills remains limited. This study aims to assess the effect of the RME approach on students’ critical thinking and collaborative skill in mathematics learning. A quantitative approach using a quasi-experimental pretest–posttest control group design involving sixty students, divided into an experimental group receiving RME instruction (n = 30) and a control group receiving conventional instruction (n = 30). The research instruments included a critical thinking skills test and an observation-based collaboration skills assessment. Data were analyzed using Multivariate analysis of Covariance to assess the combined effects of RME while controlling for initial abilities .The results revealed that the experimental group ashowed significantly higher posttest scores in critical thinking skills (M = 82.15) compored to the control group (M = 70.46), with N-Gain scores of 0.61 and 0.35, respectively. Similarly, students’ collaborative skills in the experimental group (M = 84.27) were higher than those in the control group (M = 71.15). Multivariate analysis confirmed a statistically significant effect of RME on both critical thinking and collaboration. These findings suggest that RME effectively enhances students' cognitive and social competencies and can serve as an alternative strategy for mathematics instruction.]]>

<![CDATA[This research is motivated by the low mathematics learning outcomes of eighth grade students of SMPN 12 Padang. This study aims to determine whether student learning outcomes with the implementation of the Think Pair Share (TPS) model are better than the implementation of conventional learning at SMPN 12 Padang. This type of research is an experimental study with a True Experimental design with a posttest-only control group design. This study was conducted with two sample class groups, the first experimental class that applies the TPS model and the second control class that uses the conventional learning model (PBL). The sampling of both samples was carried out using a Random Sampling technique consisting of 9 sample populations. The population of this study was eighth grade students of SMPN 12 Padang. The instrument used in this study was a Post-test in the form of an essay. The test statistics used for hypothesis testing were the t-test, because the two sample classes were not normally distributed. The results of the hypothesis test obtained t_count = 4.7 and t_table = -1.6. Since t_calculated > t_table with a significance level of 0.05, H_0 is rejected, meaning the hypothesis is accepted. Therefore, it can be concluded that the mathematics learning outcomes of eighth-grade students at SMPN 12 Padang using the Think Pair Share (TPS) model are better than those using the Problem Based Learning (PBL) model.]]>
