Abstract

Penelitian ini dilatarbelakangi oleh rendahnya kemampuan berpikir kritis matematis siswa sekolah dasar, khususnya pada materi data. Kondisi tersebut menunjukan perlunya penggunaan model pembelajaran yang mengaitkan materi pelajaran dengan konteks kehidupan nyata siswa. Penelitian ini bertujuan untuk meningkatkan kemampuan berpikir kritis matematis siswa melalui penerapan model Contextual Teaching and learning. Penelitian ini menggunakan metode Penelitian Tindakan Kelas (PTK) model Kurt Lewin yang terdiri dari empat tahap, yaitu perencanaan, Tindakan, observasi, dan refleksi. Intrumen yang digunakan meliputi tes, lembar observasi, serta dokumentasi. Subjek penelitian ini adalah 8 siswa kelas V SDN Cipelah 2. Hasil penelitian menunjukan adanya peningkatan kemampuan berpikir kritis matematis siswa. Sebelum tindakan, nilai rata-rata sebesar 38 dengan ketuntasan klasikal 12,5%. Pada siklus I meningkat menjadi 52 dengan ketuntasan 37,5%, dan pada siklus II meningkat signifikan menjadi 85 dengan ketuntasan mencapai 100%. Dapat disimpulkan bahwa penerapan model CTL efektif dalam meningkatkan kemampuan berpikir kritis matematis siswa sekolah dasar.

Abstract

This study aimed to analyze the impact of digital-based learning media on the Science and Social Studies (IPAS) literacy of fourth-grade elementary school students. The research employed a quantitative approach using a Pre-Experimental Design with a One Group Pretest–Posttest Design. The participants consisted of 23 fourth-grade students at SDN Kamurang 1, Karawang Regency, selected through a total sampling technique. Data were collected through IPAS literacy tests, observations, and documentation, and were analyzed using descriptive statistics, the Shapiro–Wilk normality test, the Wilcoxon Signed Rank Test, N-Gain analysis, and effect size. The results showed that the mean pretest score of 51.85 increased to 73.48 on the posttest. The Wilcoxon Signed Rank Test yielded a significance value of 0.000 (p < 0.05), indicating a significant effect of digital-based learning media on students' IPAS literacy. The N-Gain score of 0.46 was categorized as moderate, while the effect size of 0.876 indicated a very large effect. Therefore, digital-based learning media were proven to be effective in improving the IPAS literacy of elementary school students

Abstract

This study aims to determine the impact of the Discovery Learning model on improving the critical thinking skills of fourth-grade elementary school students in Integrated Science and Social Studies (IPAS). The study was motivated by the low level of students' critical thinking skills caused by teacher-centered learning, which limited students' opportunities to actively analyze, investigate, and solve problems. This research employed a quantitative approach using a Pre-Experimental Design with a One-Group Pretest–Posttest Design. The research participants consisted of fourth-grade students at SDN Giriwangi. Data were collected through critical thinking tests administered before and after the implementation of the Discovery Learning model. The collected data were analyzed using descriptive statistics, prerequisite tests, and hypothesis testing to determine the effect of the treatment. The findings indicate that students' critical thinking skills improved after participating in learning activities based on the Discovery Learning model. Students demonstrated better abilities in interpreting information, analyzing problems, evaluating evidence, drawing logical conclusions, and explaining their ideas systematically. The learning process also encouraged students to become more active in observing, discussing, investigating, and constructing knowledge independently. These findings support Bruner's constructivist theory, which emphasizes that meaningful learning occurs when students discover concepts through direct experience. Therefore, the Discovery Learning model can be considered an effective learning alternative for improving elementary school students' critical thinking skills in IPAS learning.

Abstract

This study aimed to examine the effectiveness of the Project Based Learning (PjBL) model in improving the collaborative skills of fourth-grade students in Science and Social Studies (IPAS) learning. The study was motivated by students' low ability to work collaboratively, participate actively in group discussions, and share responsibilities equally. A quantitative approach was employed using the Pre-Experimental Design method with a One Group Pretest–Posttest Design. The sample consisted of 20 fourth-grade students from SDS Sartika, Karawang Regency, selected through a total sampling technique. Data were collected using a collaboration skills observation sheet. The Paired Sample T-Test revealed a significance value of 0.000 (p < 0.05), indicating a significant improvement in students' collaborative skills after the implementation of PjBL. The mean score increased from 53.50 to 84.25. The N-Gain score of 0.68 was classified as moderate, while Cohen's d value of 4.434 indicated a large effect size. Therefore, the Project Based Learning model was proven to be effective in enhancing students' collaborative skills in fourth-grade IPAS learning.

Abstract

This study was motivated by the need for innovative learning media to enhance student engagement in Pancasila Education at the elementary school level, one of which is through smartphone-assisted educational online games. The study aimed to describe the implementation of this learning media, determine students' responses and participation, and identify supporting and inhibiting factors in its implementation in Grade II Pancasila Education at SDN 2 Citeko. This study employed a qualitative descriptive approach with subjects consisting of the Grade II teacher and 25 students. Data were collected through observation, interviews, and documentation, then analyzed through data reduction, data display, and conclusion drawing. The findings revealed that the implementation of the learning media was carried out according to the learning stages and was able to increase students' enthusiasm, participation, collaboration, and understanding of the symbols and meanings of the Pancasila principles. Supporting factors included students' learning interest, teacher and school support, and availability of learning devices, while inhibiting factors included limited smartphones, unstable internet connection, and limited instructional time.
