Abstract

This study aims to produce a valid and feasible electronic student worksheet (E-LKPD) using a Game-based Learning method assisted by the Liveworksheets application on the material of two-variable linear equation systems. The research method used is developmental research with the ADDIE research model through the stages of analyze, design, develop, implementation, and evaluation. This research was conducted at SMP Negeri 109 Jakarta with data collection techniques in the form of interviews and questionnaires, which were then analyzed using a combination method with an embedded concurrent model. The validity and feasibility of the media can be found in the results of validation and suggestions and comments from expert validators, as well as assessments from teachers and students. The validity and feasibility results from the expert validators were 93.7% (very valid) and media assessments from teachers and students were 90.6% (very feasible). The results of this study indicate that the learning media developed is feasible to be used in school learning.

Abstract

This study was motivated by the low level of critical thinking skills among junior high school students in solving mathematical word probleims, as evident from previous studies and the researcher's initial observations in the field. This study aims to describe the profil of junior high school students' errors in solving mathematical story problems in terms of critical thinking skills. The method used is qualitative descriptive with 32 seventh-grade students as subjects at a public junior high school in South Tambun in the 2024/2025 academic year. The research instrument was an essay test containing five story problems developed based on critical thinking ability indicators, including providing simple explanations, providing further explanations, determining strategies and techniquies, and drawing conclusions. The data were analyzed through the stages of reduction, presentation, and conclusion drawing. The results showed that most students were in the low critical thinking ability category (63%) and the rest were in the moderate category (37%), while no students reached the high category. Students with low critical thinking abilities tended to make mistakes in almost all indicators, while students with moderate abilities were able to meet most of the indicators but were not consistent, especially in determining solution strategieis and drawing conclusions. These findings indicate that the main weakness of students lies in the aspects of strategy planning and drawing conclusions, so mathematics learning that emphasizes the development of critical thinking skills through non- routine story problems and the use of targeted assessment rubrics is needed.

Abstract

This type of study was quantitative with quasi-experimental method that aims to discover the effect of contextual teaching and learning (CTL) on students’ relational understanding ability and how much the effect is. This study was posttest only group control design. It was conducted at SMP Negeri in Tangerang. The sample of this study were choosen randomly by cluster random sampling technique, which is students of grade VIII. The experimental class consisted of 35 students that applied CTL approach, while the control class consisted 34 studensthat applied conventional study. Students’ relational understanding ability be measured with the test instrument that contain five essay questions of Pythagorean Theorem that has been tested valid and realiable. Based on the result of statistical hypothesis test using t-test, obtained that the average of students’ relational understanding ability that applied CTL approach is higher than the average of students’ relational understanding ability that applied conventional learning. This show that there is the effect of contextual teaching and learning approach on students’ relational understanding ability. As for the value of Cohen’s effect size, obtained is 69% that is included in medium category.

Abstract

This study aims to analyze the need to develop a Problem-Based Learning (PBL)-based mathematics instructional design to improve the mathematical communication skills of eighth-grade junior high school students. The study employed a descriptive approach and involved 31 eighth-grade students and a mathematics teacher at SMPN 2 Jakarta. Data were collected through observation, a mathematical communication skills test, a questionnaire, and interviews. The results of the study indicate that students’ mathematical communication skills remain low, particularly in constructing mathematical models, representing ideas in graphs, and explaining solutions in their own words. The average test score of 20.11 indicates that most students have not yet met the expected proficiency indicators. Furthermore, instruction remains teacher-centered, resulting in students being less active in communicating mathematical ideas. The results of the curriculum and conceptual analysis identified “Equations of Straight Lines” as a suitable topic to be developed through PBL-based instructional design. Thus, the results of this needs analysis serve as the basis for designing an instructional approach capable of facilitating the improvement of students’ mathematical communication skills.
