Abstract

This study aims to analyze the effect of the problem-solving model on independence and achievement in learning mathematics in the material of addition and subtraction of integers using the column pattern method for class VII students of SMP Taman Siswa Medan. This research is quantitative research, with an ex-post facto approach. The population used in this study were all grade VII students of SMP Taman Siswa Medan, with a purposive sampling technique used, so that the total sample was 41 respondents. Based on the research results, the average learning achievement score is 58. The mode value is 32, indicating that the acquisition value for the ability to understand with the greatest frequency is 32. The Problem-Solving Learning Model and independent learning simultaneously affect the mathematics learning achievement of class VII junior high school students by (R2 = 0.53) or 53%. The Problem-Solving Learning Model of students has a positive effect on the learning achievement of students in class VII junior high school mathematics. The independence of student learning has a positive effect on the mathematics achievement of class VII junior high school students.

Abstract

Mathematical connection skills and learning independence remain challenges in the formal education system, particularly among students who rely heavily on procedural memorization rather than deep conceptual understanding. This situation underscores the necessity of developing learning strategies that promote critical thinking awareness and reflection. One such strategy is the application of metacognitive techniques. This study seeks to assess the impact of metacognitive strategies on the development of mathematical connection skills and learning independence among eighth-grade students enrolled in the mathematics department at Al Washliyah Hamparan Perak Private Middle School. Employing a quantitative approach with a quasi-experimental pretest-posttest control group design, the study sample comprises two classes: an experimental group that receives instruction utilizing metacognitive strategies and a control group that receives conventional instruction. The analysis of the data revealed a substantial positive impact of metacognitive strategies on both mathematical connection skills and learning independence. Specifically, the experimental group demonstrated a significant improvement in mathematical connection skills (significance 0.000 < 0.05) and learning independence (significance 0.001 < 0.05). The average gain score for mathematical connections was 0.54735 for the experimental group and 0.28264 for the control group. Similarly, the average gain score for learning independence was 0.39870 for the experimental group and 0.19518 for the control group. Consequently, metacognitive strategies have been demonstrated to be an effective tool for enhancing both mathematical connection skills and learning independence. Their implementation in the formal education system is crucial in fostering critical thinking, self-awareness, and independent learning among students.

Abstract

This study investigates the effect of the open-ended learning strategy on students’ multiple mathematical representation and problem-solving abilities in junior high school mathematics. A quasi-experimental method employing a pretest–posttest control group design was implemented with two classes of eighth-grade students at SMP Negeri 28 Medan. The experimental group received open-ended learning, while the control group received direct instruction. Data were collected through tests of multiple mathematical representation and problem-solving ability, complemented by classroom observations. Quantitative data were analyzed using descriptive statistics, the Mann–Whitney U test, the independent samples t-test, and Spearman’s rank correlation.The results revealed that students taught using the open-ended learning strategy achieved higher posttest scores in both multiple representation and problem-solving abilities compared to those taught through direct instruction. A statistically significant difference was found in problem-solving ability (p = 0.001), while representational ability showed a positive but nonsignificant trend. Moreover, a significant positive correlation (r = 0.367, p = 0.003*) was found between students’ multiple representation and problem-solving abilities. These findings indicate that open-ended learning promotes higher-order thinking by enabling students to explore diverse solution strategies, construct meaning through multiple representations, and engage in reflective reasoning. The study highlights the pedagogical potential of open-ended learning as an effective approach to fostering conceptual understanding and creative mathematical thinking aligned with the goals of the Merdeka Curriculum.
