Abstract

This research is motivated by the low learning outcomes of students in Natural Sciences. This is because the learning model applied is not optimal and students are less interested in the learning process. Therefore, it is necessary to change the implementation of learning in the classroom by using the make a match learning model (finding card pairs) in the learning process. The formulation of the problem in this study is how the application of the make a match model can improve the learning outcomes of grade IV science at SD Negeri 200405 Hutaimbaru Jl. Sibolga, KM 4 Hutaimbaru, Kec. Hutaimbaru, Padangsidimpuan City, North Sumatra Province. This study aims to determine the application of the make a match model can improve the learning outcomes of grade IV science at SD Negeri 200405 Hutaimbaru Jl. Sibolga, KM 4 Hutaimbaru, Kec. Hutaimbaru, Padangsidimpuan City, North Sumatra Province. The type of this research is Classroom Action Research (CAR) at the planning, action, observation and reflection stages at SD Negeri 200405 Hutaimbaru. The data collection instruments used were tests and observations. The results of the study showed that the application of the make a match model can improve student learning outcomes. This is evidenced by the increase in the average value and completeness of student learning outcomes, namely in the pre-cycle an average of 53.7% and completeness of 13% (3 out of 24 students). In cycle I, meeting I, the average score of student scores was 60.2% and student completeness was 39% (5 out of 24 students). While cycle I, meeting II, the average score of student scores was 72.5% and student completeness was 50% (12 out of 24 students). In cycle I, meeting I, the average score of student scores was 79.1% and student completeness was 71% (17 out of 24 students). While cycle II meeting II became the average score of student scores 92.9% and student completion 92% (22 out of 24 students). It can be concluded that the application of the make a match learning model can improve the learning outcomes of grade IV science at SD Negeri 200405 Hutaimbaru.

Abstract

Measures of central tendency, such as the mean, median, and mode, are fundamental concepts in statistics that can be used to support decision-making. The purpose of this study is to describe how university students reason about measures of central tendency when comparing two age distributions of patients presented in the form of frequency polygons, from a commognitive perspective. This study employs a descriptive qualitative method with an exploratory approach. A total of 37 students participated in the study, four of whom were selected as research subjects—two representing the calculative category and two representing the visual-interpretative category. The research instruments consisted of one problem related to measures of central tendency and an interview guide. The problem included three questions, each presenting data in the form of frequency polygons. The data were thematically analyzed using Sfard’s commognitive framework, focusing on four components: word use, visual mediators, routines, and narratives. The findings reveal that students in the calculative category predominantly used visual mediators and routines. In contrast, students in the visual-interpretative category emphasized the use of word use to construct narratives. Keywords: commognitive, reasoning, measures of central tendency, frequency polygon

Abstract

This study aims to analyze the mathematical problem-solving abilities of 25 eleventh-gradestudents at SMA Negeri 1 Barumun Tengah in solving Higher Order Thinking Skills (HOTS)questions related to arithmetic and geometric sequences. The research employed a descriptivequalitative approach with data collected through written tests, interviews, and observations. Thefindings indicate that most students struggled to solve HOTS questions systematically. Based onPolya’s problem-solving steps, 80% of students were able to understand the problem, 60% coulddevise a strategy, 52% were able to carry out the strategy, and only 36% evaluated their resultsindependently. The greatest difficulties were found in the planning and evaluation stages, primarilydue to low critical thinking skills, lack of exposure to contextual questions, and the dominance ofprocedural-based teaching. These findings highlight the importance of systematically integratingHOTS questions into mathematics instruction to foster students’ higher-order thinking skills.
