Abstract

Pembelajaran matematika yang masih cenderung teacher centered dalam proses pembelajaran yang dilakukan di kelas, serta siswa dibiarkan puas dengan hanya mengerjakan soal-soal rutin. Tujuan penelitian, yaitu untuk mengetahui efektivitas penerapan bahan ajar cetak handout dengan model obsorn terhadap kemampuan berpikir kritis matematis siswa. Penelitian ini merupakan penelitian eksperimen dengan nonequivalent control group design. Populasi yang digunakan adalah kelas IV SD Negeri Bendan Ngisor. Subjek penelitian ini kelas IV A sebagai kelas eksperimen dengan 23 siswa dan kelas IV B sebagai kelas kontrol dengan 25 siswa. Teknik pengambilan sampel dalam penelitian ini yaitu menggunakan teknik purposive sampling. Adapun teknik analisis data penelitian ini yaitu menggunakan Uji Independent T test. Hasil yang diperoleh dalam penelitian ini yaitu menunjukan bahwa pembelajaran yang menggunakan handout dengan model pembelajaran obsern efektif dalam meningkatkan kemampuan berpikir kritis siswa, hasil perhitungan diperoleh ?ℎ????? = 2,57, dengan ?=5%, ?? = 46 diperoleh ?????? = 2,02. Karena ?ℎ????? > ?????? rata-rata hasil tes kemampuan berpikir kritis siswa pada kelas eksperimen yang menggunakan handout dengan model pembelajaran osborn lebih tinggi dibandingkan dengan kelas kontrol yang menggunakan model pembelajaran osborn tanpa handout dalam meningkatkan kemampuan berpikir kritis matematis siswa, hal tersebut ditunjukan juga dengan nilai N-Gain yang diperoleh eksperimen lebih tinggi kontrol. Peningkatan kelas eksperimen memperoleh nilai Gain yaitu 0,50 dengan kategori tinggi dan kelas kontrol memperoleh nilai Gain 0,17 dengan kategori rendah. Hal tersebut dapat disimpulkan bahwa siswa yang menggunakan handout dengan model pembelajaran osborn lebih efektif

Abstract

This study aimed at comprehensively analyzing critical thinking patterns in elementary school students through the Grounded Theory method. The design used was a case study. This study involved 25 fourth grade students at Kedung Krisik Elementary School, Cirebon City. Data collection was carried out through critical thinking math test questions; and interviews between researchers and students after completing the test questions. The analysis process was carried out by giving tests to students. The results of this study reveals that students' critical thinking skills in mathematics at the elementary school are divided into three categories, namely CTA 3, CTA 2, and CTA 1. It could be seen that critical thinking skills in mathematics can be improved by practicing working on questions related to mathematics learning, especially in the form of contextual questions. The Watson-Glaser Critical Thinking Appraisal (CTA) critical thinking assessment models could be applied to measure critical thinking skills themselves.

Abstract

Mathematics is a lesson that many students do not like, so to change it all required interactive teaching materials that can foster student self-reliance. The purpose of this research is to know whether there is influence of response of the use of mathematics material supplement comic to student self-reliance. The method used in this research is descriptive statistical method with research design The One-Shot Case Study Design. The result of hypothesis obtained Fcount = 17,198 and Ftable = 3,14 based on Ha hypothesis criteria. Keywords: Teaching Materials, Comic Mathematics, Independence.

Abstract

This study aims to examine the effectiveness of the EXCHIL Model (Experience-Based Contextual Hybrid Learning) in improving the speaking skills of students in the English Language Education Study Program at Institut Prima Bangsa. Using a convergent parallel mixed-methods design with a descriptive approach, the study involved 52 students. Quantitative data were obtained through questionnaires and pre-test–post-test scores, while qualitative data were collected from observations and in-depth interviews with three students. The main challenges identified were limited vocabulary, pronunciation difficulties, and speaking anxiety. Results showed a substantial improvement in students’ speaking performance, with the average pre-test score of 66.2 to 82.4 in the post-test. The score distribution also shifted positively, as more students achieved scores in the 75–85 range, while fewer scored below 70. Qualitative findings revealed enhanced fluency, confidence, and willingness to speak after the implementation of the model. These findings suggest that integrating experiential, contextual, and hybrid elements can foster student-centered language learning adaptable to diverse digital environments. Overall, the results highlight the potential of the EXCHIL Model for advancing 21st-century EFL pedagogy.
