Abstract

This research examines the effect of the discovery learning model on higher-order thinking skills in chemistry subjects at the high school level in Indonesia with a total sample of 230 students. The research method is a meta-analysis study with a range of research data from 2015-2024 based on Google Scholar indexed by Sinta. Heterogeneity test analysis using JASP version 0.8.5 shows a τ² value of 0.236 and a τ value of 0.485, with an I² value approaching 100% (CI: 74.015%–98.358%). The results indicate a high level of heterogeneity (98.358%). Therefore, a random effects model is used in the analysis. The meta-analysis results suggest that discovery learning significantly affects higher-order thinking skills (z = 4.730; p < 0.001; 95% CI). Funnel plot and Egger's tests did not show publication bias, supported by a fail-safe N value 488. The results of this study reinforce empirical evidence that discovery learning is a practical approach to chemistry learning.

Abstract

Penelitian ini bertujuan untuk menganalisis pemahaman siswa terhadap materi struktur atom dan sistem periodik unsur serta hubungannya dengan minat belajar siswa. Pendekatan yang digunakan adalah kuantitatif deskriptif dengan populasi siswa kelas X di salah satu SMA negeri. Sampel penelitian terdiri dari 100 siswa yang dipilih secara purposive. Instrumen yang digunakan meliputi tes objektif untuk mengukur pemahaman konsep dan angket minat belajar siswa. Data yang diperoleh dianalisis menggunakan statistik deskriptif berupa persentase, rata-rata, dan standar deviasi, serta uji korelasi Pearson untuk melihat hubungan antara minat belajar dengan tingkat pemahaman siswa. Hasil penelitian menunjukkan bahwa sebagian besar siswa memiliki tingkat pemahaman sedang terhadap struktur atom dan sistem periodik unsur. Selain itu, ditemukan adanya hubungan positif yang signifikan antara minat belajar dengan pemahaman siswa. Semakin tinggi minat belajar siswa, semakin baik pula pemahamannya terhadap materi. Temuan ini menunjukkan pentingnya pengembangan strategi pembelajaran yang tidak hanya fokus pada penguasaan konsep, tetapi juga mampu meningkatkan minat belajar siswa agar tercapai hasil belajar yang optimal dalam pembelajaran kimia.

Abstract

This study aims to develop an interactive e-module based on green chemistry in the reaction rate material to improve learning outcomes and foster students' interest in learning. The research employed the Research and Development (R&D) method using the 4D development model (Define, Design, Develop, Disseminate), which in this study was limited to the Develop stage. The research subjects consisted of 2 lecturers, 1 chemistry teacher, and 32 students from from the Grade XI Science A-1 class at State Islamic Senior High School 1 Medan (MAN 1 Medan), selected through purposive sampling. The research instruments included test instruments (pretest and posttest questions) and non-test instruments (validation questionnaires and student learning interest questionnaires). Based on expert validation, the interactive e-module was declared highly feasible with an overall average score of 82.00%. In the trial phase, the e-module showed an improvement in student learning outcomes with an N-gain score of 0.69, categorized as moderate, and student interest in learning reached 74%, also falling into the moderate category. Keyword:        Interactive e-module, green chemistry, reaction rate, learning outcomes, learning interest.

Abstract

Penelitian ini bertujuan untuk menganalisis hubungan penerapan Student Centered Learning (SCL) menggunakan metode Certainty of Response Index (CRI) model Two-Tier, yang melibatkan soal dan tingkat keyakinan mahasiswa terhadap pemahaman materi Kimia Unsur. Penelitian dilakukan pada delapan submateri, yaitu golongan IA (6%), golongan IIA (9%), golongan VIIA (13%), golongan VIIIA (13%), unsur periode 3 (16%), unsur periode 4 (6%), ion kompleks (9%), dan senyawa kompleks (19%). Hasil menunjukkan bahwa senyawa kompleks memiliki tingkat miskonsepsi tertinggi, sedangkan golongan IA dan unsur periode 4 terendah. Pendekatan SCL terbukti efektif dalam meningkatkan pemahaman konsep dasar, tetapi diperlukan strategi pembelajaran tambahan untuk mengurangi miskonsepsi pada submateri tertentu, sehingga kualitas pembelajaran kimia unsur dapat ditingkatkan secara menyeluruh
