Abstract

Mathematical disposition is one aspect that influences a person's success in learning, because mathematical disposition is a person's attitude towards appreciating mathematics. This research aims to describe the mathematical disposition of students in the Mathematics Education Study Program at PGRI University of West Sumatra in the Basic Statistics course. The research subjects were 28 students from the class of 2021. The instruments used were a mathematics disposition questionnaire and interview sheets. Mathematical disposition is seen using 6 indicators, namely: 1) self-confidence, 2) curiosity, 3) feeling capable, 4) happy, diligent and diligent, 5) flexible, 6) reflective. The data analysis technique uses quantitative descriptive analysis techniques in the form of percentages. The results of this research show that learning outcomes have increased from the average pretest score (62) to posttest score (87). Based on the results of the Shapiro-Wilk statistical test, it was obtained that 0.03 was smaller than 0.05 and had a normal distribution, so the results of this research were acceptable and had a significant effect on students' mathematical disposition through the CTL approach.

Abstract

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.

Abstract

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.

Abstract

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.
