Abstract

Melatih dan mengembangkan kemampuan berpikir kritis sangat penting bagi siswa untuk mendapatkan hasil belajar yang optimal. Salah satu strategi yang dapat dilakukan guru dalam melatih dan meningkatkan kemampuan berpikir kritis siswa adalah dengan mengembangkan bahan ajar berupa modul berbasis inkuiri. Penelitian ini secara umum bertujuan untuk menghasilkan modul berbasis inkuiri pada materi ekosistem yang layak, praktis dan efektif dalam meningkatkan kemampuan berpikir kritis siswa di kelas X SMA. Penelitian ini termasuk jenis penelitian pengembangan menggunakan model ADDIE. Subjek penelitian adalah siswa kelas X SMA Negeri 3 Tebing Tinggi sebanyak 2 kelas terdiri dari kelas eksperimen (34 siswa) dan kelas kontrol (34 siswa). Data penelitian dikumpulkan melalui lembar validasi ahli, lembar observasi, lembar angket serta instrumen tes kemampuan berpikir kritis. Teknik analisis data yang digunakan meliputi analisis kelayakan, analisis kepraktisan dan analisis keefektifan modul dengan pendekatan independent sampel t-test. Hasil penelitian menunjukkan bahwa modul berbasis inkuiri pada materi ekosistem kelas X SMA telah memenuhi kriteria sangat layak berdasarkan penilaian tim validator ahli materi (85,1%) maupun penilaian tim validator ahli media/desain (94,0%); memenuhi kriteria sangat praktis berdasarkan hasil pengamatan aktivitas guru (89,0%) dan aktivitas siswa (83,8%); serta efektif diterapkan untuk meningkatkan kemampuan berpikir kritis siswa yang dibuktikan dari persentase ketuntasan belajar klasikal siswa kelas eksperimen yang mencapai 97,1% serta pengujian secara statistik dengan nilai thitung > thitung (4,945 > 1,665) dan nilai probabilitas sebesar 0,000 < 0,05. Guru biologi memberikan respon yang sangat baik (86,3%) terhadap modul yang dihasilkan, serta rata-rata siswa juga memberikan respon yang tergolong baik (79,9%)

Abstract

This study aimed to analyze the effectiveness of an environment-based Biodiversity Flipbook E-Module in improving tenth-grade students’ understanding of biology and their scientific process skills at SMA Negeri 21 Medan. The study employed a one-group pretest–posttest design involving 36 students. Research instruments included a validated biology comprehension test and an observation sheet used to assess students’ scientific process skills during three environment-based learning sessions. Data were analyzed using the N-gain score and descriptive statistics. The results showed that the mean pretest score of 33.81 increased to 83.88 in the posttest, resulting in an N-gain score of 0.76, which falls into the high category. Students’ scientific process skills were classified as very good across all learning sessions and demonstrated an increasing trend during the final meeting. These findings indicate that the environment-based Biodiversity Flipbook E-Module is effective in enhancing students’ understanding of biological concepts and their scientific process skills through contextual learning grounded in real environmental exploration.

Abstract

This study aimed to identify the diversity of gastropods at Lagundri Beach, South Nias, and to develop and evaluate the feasibility, practicality, and effectiveness of a booklet as a biology learning resource for senior high school students on the topic of biodiversity. This research employed a Research and Development (R&D) approach using the 4D model (define, design, develop, disseminate). The research subjects consisted of five validators, two teachers, and 31 students. Data were analyzed quantitatively and qualitatively through validity, practicality, and effectiveness tests, with effectiveness assessed using normality, homogeneity, t-test, and N-gain analyses. The results showed that the gastropod diversity index was 3.31, which falls into the high category. The developed booklet was classified as highly feasible (average >88%), highly practical (≥91%), and moderately effective, with an N-gain value of 63.13%. The t-test indicated a significant difference between the experimental and control classes (t = 4.80; p < 0.05). Therefore, this booklet based on local potential is suitable for use as a supplementary learning resource to improve students’ conceptual understanding and biodiversity literacy.
