Abstract

Telah tersedia modul stoikiometri berbasis guided discovery learning yang telah teruji valid dan praktis, namun belum diuji efektivitasnya terhadap pembelajaran, sehingga belum dikatakan layak untuk dijadikan sebagai bahan ajar dan disebarkan kepada wilayah yang lebih luas. Penelitian ini bertujuan untuk menganalisis efektivitas modul stoikiometri berbasis guided discovery learning terhadap hasil belajar siswa kelas X MAN 2 Padang. Jenis penelitian yang dilakukan adalah quasi-experiment dengan rancangan pretest-posttest control group design. Pengambilan sampel menggunakan teknik simple random sampling, sehingga terpilih kelas X IPA 9 sebagai kelas eksperimen dan kelas X IPA 6 sebagai kelas kontrol. Kelas eksperimen dalam pembelajaran menggunakan modul berbasis guided discovery learning, sementara kelas kontrol menggunakan sumber lain. Instrumen penelitian berupa soal tes pretest-posttest yang telah valid,reliabel, memiliki daya pembeda soal dan indeks kesukaran yang baik. Data yang diperoleh dianalisis dengan menggunakan uji n-gain, uji normalitas, uji homogenitas, dan uji hipotesis. Keefektifan modul dianalisis berdasarkan nilai n-gain. Berdasarkan pengolahan data, didapatkan rata-rata nilai n-gain kelas eksperimen lebih tinggi dari rata-rata n-gain kelas kontrol yaitu pada kelas eksperimen sebesar 0,721 sedangkan kelas kontrol 0,620. Berdasarkan uji hipotesis menggunakan uji-t diperoleh nilai thitung ttabel yaitu 4,18 1,99. Kesimpulannya, pengggunaan modul stoikiometri berbasis guided discovery learning efektif dalam meningkatkan hasil belajar siswa.

Abstract

In an effort to achieve the development of students' critical thinking skills in elementary school science learning, various innovative learning models can be used, one of which is the Project Based Learning (PjBL) model. The PjBL model is a learning method that can improve critical thinking skills through problem solving. This type of research is a quantitative meta-analysis study. The meta-analysis study aims to determine how big the effect of the PjBL model is on students' critical thinking skills in elementary school science learning? The collection of articles using the publish or perish application with the keywords project based learning model, critical thinking, elementary school science learning as many as 200 articles and 12 theses. Articles that meet the inclusion criteria are analyzed by calculating the effect size of each journal and thesis. The average effect size analysis of 0.59 is in the moderate category. The PjBL model has an effect on elementary school students' critical thinking skills with r RE = 0.59 in the moderate category. This shows that the application of the PjBL model has an effect on students' critical thinking skills in elementary school science learning. PjBL-based science learning allows students to apply and develop theories, skills, and techniques to solve problems. PjBL enriches students' learning experiences and knowledge, providing more meaningful education in innovative learning

Abstract

This meta-analysis investigates the effectiveness of the Problem-Based Learning (PBL) model in enhancing students' critical thinking and problem-solving skills in science education. A total of 42 peer-reviewed articles published between 2020 and 2024 were analyzed, covering diverse educational levels and scientific disciplines. The analysis revealed a large average effect size (ES = 0.798; 95% CI: 0.782–0.813), indicating a strong positive impact of PBL. The low standard error (SE = 0.043–0.060) reflects high estimation precision. Statistical tests, including funnel plot symmetry, Trim-and-Fill analysis (p = 0.991), and Egger’s regression test (p = 0.947), confirm the absence of significant publication bias. Moreover, residual heterogeneity was minimal (τ² = 0.000), validating the appropriateness of the fixed-effects model. These findings provide robust empirical evidence that PBL is consistently effective across various contexts in improving students’ 21st-century competencies. The study offers meaningful implications for educators and policymakers in designing science learning strategies that foster higher-order thinking skills.

Abstract

The study aims to develop an acid-base e-module based on guided discovery learning using React Native to improve the problem-solving skills of senior high school students. The research method is Educational Design Research (EDR) using the Plomp model. The e-module using React Native is presented in the form of a mobile application that can be accessed on smartphones. The presentation of acid-base material in the e-module is adapted to the syntax of Guided Discovery Learning. The e-module was validated by 5 validators, including 3 subject matter experts and 2 media experts, using a questionnaire analysed with Aiken's V. Practicality was assessed by 9 students representing low, medium, and high ability categories using a questionnaire in the small group stage, analysed using achievement percentages. Effectiveness was determined by comparing pre-test and post-test scores of students using the N-gain formula. The validation results of the acid-base e-module using React Native were 0.90, categorized as valid, and the practicality of the e-module was 92%, categorized as highly practical. Effectiveness was obtained from N-gain data of 0.71, categorised as high (sufficiently effective). Hypothesis testing was conducted using the Wilcoxon test because the data was not normally distributed, with a sign of < 0.001, indicating that the acid-base e-module based on guided discovery learning using React Native can improve the problem-solving skills of senior high school students in phase F.

Abstract

This research aims to develop a chemistry learning e-module for acids and bases based on guided discovery learning, incorporating elements of ethnoscience to improve students' literacy and numeracy. The guided discovery learning approach was chosen to encourage students to actively construct knowledge through guidance, while the integration of ethnoscience aims to link chemistry concepts with local wisdom to increase student relevance and understanding. The research method used was Research and Development (R&D) with the 4D development model (Define, Design, Develop, Disseminate). The research instruments included an expert validation sheet, a student response questionnaire, and literacy and numeracy tests. The validation results indicated that the e-module was highly feasible in terms of content, presentation, and language. A limited trial demonstrated significant improvements in students' literacy and numeracy skills after using the e-module. Therefore, this e-module is effective as an alternative learning medium for contextual and meaningful chemistry learning.

Abstract

The implementation of the independent curriculum at the senior high school level can be an opportunity for educators to develop alternative teaching materials that according to the latest curriculum standards. One alternative teaching material that can be used is the module. This study aims to develop a basic chemical law module based on Problem Based Learning integrated with green chemistry that is valid, practical and effective. This type of research is educational development research (educational design research) or known as EDR. The test subjects for this study were three chemistry lecturers, two chemistry teachers, and tenth grade students. The results of the study obtained a construct validity of 0.90 and a content validity of 0.91. The results of practicality tests by teachers and students are included in the very practical group with respective values of 0.88 and 0.84. The results of the t test on student learning outcomes showed that t-count (2.87) is bigger than t-table (1.67), and the value of science process skills in the experimental class was higher than the control class. Therefore, it can be said that the module based on problem base learning integrated with green chemistry on basic chemical law material is valid, practicable, and effective. Therefore, it can be said that the modules made are reliable and useful for use in the learning process.
