Menyusun dan mengembangkan instrumen yang handal dan layak digunakan sebagai pengumpul data kemampuan berpikir kritis matematika siswa adalah salah satu upaya. Penelitian ini adalah merupakan pengembangan instrumen tes dengan metode Research and Development. Penelitian dilakukan di SMA Negeri Tangerang Selatan dengan target populasi siswa kelas X IPA dan populasi terjangkau adalah siswa kelas X IPA SMAN 3 dan SMAN 12 Tangerang Selatan. Dari hasil penelitian diperoleh bahwa Confirmatory Factor Analysis (CFA) Kaisser-Meyer-Olkin Measure of Sampling Adequacy (KMO-MSA) sebesar 0,566 > 0,5 sehingga instrumen memenuhi syarat validitas dilihat dari sampel yang digunakan. Sedangkan untuk skor Anti-image korelasi, sembilan item menunjukkan nilai ? 0,5 dan ada tiga item yang nilainya masih <0,5 yaitu b1, b5, dan b11. Kemudian dilakukan rotasi tanpa melibatkan 3 item dan diperoleh nilai loading faktor ? 0,5 (N = 143), disimpulkan bahwa indikator (item) yang digunakan pada variabel berpikir kritis matematika dinyatakan valid.The spread of uncontrolled information supported by advances in information technology as a feature of the 21st century requires critical thinking skills to select the information received so that mathematical critical thinking skills become important for students to be improved through various activities that must be carried out. Arranging and developing instruments that are reliable and appropriate for use as data collectors for students' critical thinking skills in mathematics is one of the efforts. This research is the development of a test instrument with the Research and Development method. The research was conducted at SMA Negeri Tangerang Selatan with the target population being students in class X IPA, and the accessible population was students in class X IPA at SMAN 3 and SMAN 12 Tangerang Selatan.. From the research results, it was found that the Kaisser-Meyer-Olkin Confirmatory Factor Analysis (CFA) Measure of Sampling Adequacy (KMO-MSA) was 0.566 > 0.5 so that the instrument met the validity requirements seen from the sample used. As for the correlation Anti-image score, nine items show a value ? 0.5 and there are three items whose value is still <0.5, namely b1, b5, and b11. Afterwards, a rotation was carried out without 3 elements and a load factor of 0.5 (N = 143) was obtained. It was concluded that the indicators (items) used in the mathematical critical thinking variable were declared valid.

Abstract

Bruner's theory is particularly notable for its application in mathematics, as it outlines three steps in the teaching process: enactive, iconic, and symbolic. This research aims to implement Bruner's theory in teaching Angles on circles to improve problem-solving skills. The research method is a quasi-experiment with a posttest-only control group design. Using cluster random sampling, two classes from one of the junior high schools in Jakarta were selected as samples: the first as an experimental class of 30 students, who learned using Bruner's theory, and the second as a control class of 31 students, who learned with a conventional approach. The instrument is a mathematical problem-solving test in the form of an essay test of four questions. The questions are given at the end of the lesson, and the instruments have been validated through content validity and empirical validity. The results show that, through t-test analyses, it was found that students’ problem-solving skills, who learn using Bruner's theory, are higher than those of students who learn using conventional methods. It demonstrates that teaching using Bruner’s theory is effective in improving students’ problem-solving skills, particularly in the Area of Angles on circles.

Abstract

This study aims to develop mathematics teaching materials based on an open-ended approach to facilitate computational thinking skills in the topic of polyhedrons. The product developed is a printed teaching material, namely the Polyhedron Module based on the Open-Ended Approach. This research uses the Research and Development (RD) method and employs the ADDIE development model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The test subjects in this study were grade VIII-2 students of MTsN 35 Jakarta and eight validators, consisting of three expert lecturers from the Mathematics Education department and five mathematics teachers from SMP/MTs as practitioners. The results of the study showed that (a) based on expert validation, a score of 0.92 was obtained, indicating that the module is very valid; (b) based on practitioner validation, a score of 0.86 was obtained, and the student response questionnaire yielded a score of 0.82, indicating that the module is very practical; and (c) based on the results of the students' computational thinking skills test, 77.42% of the 31 students achieved scores that met the minimum passing criteria (KKM), with an overall average score of 80, indicating that the module is effective in facilitating computational thinking skills. Therefore, the Polyhedron Module based on the Open-Ended Approach meets the criteria of being valid, practical, and effective.

Abstract

Conceptual understanding in mathematics is an essential competency that students must master to achieve learning objectives. This study aims to determine the effect of the Bridging Analogy approach on students’ conceptual understanding of mathematics in Grade VIII at a junior high school in South Jakarta during the 2025/2026 academic year. The research employed a quasi-experimental method with a randomized two group post-test only design, involving two sample groups: class VIII C ar the experimental group and class VIII B as the control group, each consisting of 33 students. The research instrument consisted of a multiple-choice test with 30 items on the topic of relations and functions. Data were analyzed using the t-test with the aid of SPSS software. The results showed that the experimental group obtained an average score of 64.34 with a variance of 201.03, while the control group achieved an average score of 52.73 with a variance of 201.01. The hypothesis testing yielded at t-value 0f 3.328, which was greater than the t-table value of 1.998 at a 5% significance level, thus the alternative hypothesis was accepted. Therefore, it can be concluded that the implementation of the Bridging Analogy approach significantly improves students’ mathematical conceptual understanding. However, despite the statistical significance, the average score has not yet reached the minimum mastery criterion, suggesting the need for further practical improvements.
