Abstract

Penelitian ini dilatarbelakangi oleh rendahnya kemampuan pemahaman konsep matematika siswa kelas III SD, yang disebabkan oleh minimnya penggunaan media pembelajaran berbasis teknologi yang menarik dan interaktif. Tujuan penelitian ini adalah untuk mengembangkan media video animasi berbantuan aplikasi Canva dengan model Problem Based Learning (PBL) guna meningkatkan kemampuan pemahaman konsep pada siswa kelas III Sekolah Dasar. Penelitian ini menggunakan metode Research and Development (R&D) dengan model pengembangan ADDIE (Analysis, Design, Development, Implementation, Evaluation). Subjek penelitian adalah siswa kelas III SD sebanyak 35 orang. Instrumen penelitian yang digunakan meliputi angket validasi ahli, angket respons siswa, dan tes pemahaman konsep. Hasil validasi ahli materi memperoleh persentase sebesar 95%, ahli media sebesar 94%, sehingga keseluruhan produk dinyatakan sangat layak. Hasil uji coba menunjukkan peningkatan rata-rata nilai pemahaman konsep siswa dari 39,6 (pretest) menjadi 82,34 (posttest), dengan nilai N-Gain sebesar 0,71 yang termasuk kategori tinggi. Dengan demikian, media video animasi berbantuan Canva dengan model Problem Based Learning terbukti efektif dalam meningkatkan kemampuan pemahaman konsep matematika siswa kelas III SD.

Abstract

This research is a development research which aims to develop liveworksheet-based worksheets using a scientific approach to statistical material. The method used in this study is Research and Development (R&D) with the 4D model which is limited to step 3, namely define, design and development. The instrument used was in the form of a written test totaling 5 questions and non-tes in the form of a student response questionnaire with a total of 30 statements. The subjects in this study were 10 class IX students as a limited test sample and 25 class VIII students as a broad test sample at Bhakti Mulya Batujajar Middle School, West Bandung Regency. The results of this study indicate that the LKPD that has been developed obtains results in the "Very Valid" feasibility category with the student's response to the LKPD that has been developed is "Practical" LKPD. So the LKPD developed is an LKPD that is effectively used by students.

Abstract

This research aims to see the improvement in mathematical problem solving abilities of class VII middle school students through the Discovery Learning Learning Model assisted by animated videos. This research is experimental research.   The population in this study were class VII students, while the sample was students from class VII A as the experimental class and VII B as the control class at SMP IT Al-ajwa Al-Islamy. This research uses the Nonequivalent Pretest-Posttest Control Group Design research design. The research instrument used was an essay question with a total of 7 questions.  The data obtained will be analyzed and processed using a 2 independent sample test using a normality test, a homogeneity test first as a prerequisite and followed by a t-test.  The results of hypothesis testing using the Independent Sample T-Test show that the significant value is 0.000 ≤ 0.05, so is rejected.  So, it can be concluded that the Discovery Learning Model assisted by animated videos to improve the mathematical problem solving abilities of Al-Ajwa Al-Islamy IT Middle School students is better and has increased.

Abstract

The aim of this research is to examine the influence of the Realistic Mathematics Education (RME) approach in improving students' mathematical communication ability. In this research, a quasi-experiment was used, with the research using the non-equivalent pretest-posttest control group design. Eighth grade students at PGRI 1 Cimahi Middle School were the subjects of the research. To measure mathematical communication ability, data was obtained from four test questions that had been tested previously. Next, the data obtained will be analyzed and processed using analysis of 2 dependent samples using a normality test first, followed by a paired t-test. Mathematical communication ability improve much better for students who use the RME Approach compared to students who use the regular learning approach.

Abstract

This research aims to examine the enhancement of mathematical problem-solving skills and the application of learning through the RME approach with the assistance of VBA Excel. The method used in this research is a quasi-experimental design with a pretest-posttest control group involving two groups of students: the experimental group, which received treatment through the RME approach assisted by VBA Excel, with the outcome observed being the students' mathematical problem-solving abilities. Meanwhile, the control group received instruction using the conventional approach. The population in this study is all eighth-grade students at SMP Negeri 4 Cimahi. The research sample consists of two randomly selected classes, namely the experimental class with 30 students and the control class with 30 students at SMPN 4 Cimahi. The instrument used consists of four open-ended questions assessing mathematical problem-solving abilities on the topic of the Pythagorean theorem. Data analysis was conducted using normality tests, homogeneity tests, and t-tests. The research results indicate that the Realistic Mathematics Education (RME) approach assisted by VBA Excel can enhance students' mathematical problem-solving abilities compared to the conventional approach in the learning process.

Abstract

This research aims to examine the improvement of mathematical communication skills of junior high school students in grade VII using the Problem Based Learning (PBL) model. The method used is quantitative with a quasi-experimental design involving two sample groups. One group is called the experimental class because it receives learning with the Problem Based Learning (PBL) model, the other is the control class whose learning uses the conventional model. The first meeting was given a pre-test and the last meeting was given a post-test. The population in this study was all grade VII of SMP PGRI Cibeureum. Then 2 classes were determined as samples, namely class VII-A as the experimental class and class VII-C as the control class. The data collection technique in this study used an instrument of students' mathematical communication skills which was given twice, namely during the Pre-test and Post-test. Data processing and analysis using Microsoft Excel application and SPSS software ver 25.0, the results of this research analysis show that the increase in mathematical communication skills of students of SMP PGRI Cibeureum whose learning uses the Problem Based Learning (PBL) Model is better than those who use conventional learning.

Abstract

This study aims to observe the process of students' critical mathematic alabilities in the context of their initial mathematical knowledge. The research utilized a qualitative approach with a descriptive method. The research was conducted at SMP Negeri 7 Cimahi with a sample of 34 students from class VIII-E. The results show that students with good initial mathematical abilities demonstrate better critical thinking skills compared to students with lower initial abilities. High-category students are able to provide detailed answers, supported by appropriate evidence and conclusions, despite minor errors. Medium-category students can answer correctly and provide sufficient reasons and evidence, although sometimes imprecise. Low-category students can provide correct answers but lack supporting evidence and reasons. These findings indicate a positive correlation between initial mathematical abilities and critical mathematical thinking skills. Therefore, improving students' critical mathematical thinking skills requires efforts to enhance their initial mathematical abilities through adaptive and effective teaching methods.
