Abstract

This research aligns with UMS RIP Theme 5 concerning the improvement of education and learning quality. Socioscientific Blended Project-Based Learning (SSI-PjBL) is a learning model that actively engages students through online and face-to-face activities, including reading, discussion, experimentation, data analysis, and problem-solving related to socioscientific issues in society. This study aimed to determine the effectiveness of the SSI-PjBL model in improving the higher-order thinking skills (HOTS) of biology education students at the Faculty of Teacher Training and Education (FKIP) UMS. This study employed a quasi-experimental design involving two groups of 40 students, consisting of an experimental group (20 students) taught using the SSI-PjBL model and a control group (20 students) taught using the conventional Project-Based Learning (PjBL) model. HOTS indicators measured in this study included critical thinking, analysis, evaluation, and problem-solving skills. Data were collected using HOTS-based pretest and posttest essay instruments. Data analysis was conducted using hypothesis testing and effect size analysis. Prior to hypothesis testing, assumption tests including normality and homogeneity tests were performed. Since the data were normally distributed, independent sample t-test was used as a parametric statistical test. The results showed a significant improvement in students’ HOTS in the experimental class compared to the control class. Furthermore, the effect size was calculated using Cohen’s effect size formula and produced a value of 3,190, which was categorized as high according to Cohen’s criteria. These findings indicate that the SSI-PjBL model has a strong effect on improving students’ higher-order thinking skills and can be considered an effective learning approach to support 21st-century biology education.

Abstract

Rendahnya literasi lingkungan siswa menunjukkan perlunya bahan ajar kontekstual yang mengaitkan pembelajaran Biologi dengan potensi hayati lokal. Penelitian ini bertujuan untuk mengembangkan dan memvalidasi konten modul elektronik (e-module) berbasis tanaman obat untuk meningkatkan literasi lingkungan siswa. Studi ini mengisi kesenjangan penelitian karena masih terbatasnya bahan ajar digital yang secara khusus mengintegrasikan tanaman obat dengan pengembangan literasi lingkungan yang tervalidasi secara sistematis. Penelitian ini menggunakan desain research and development yang meliputi tahap perancangan e-module, validasi oleh tujuh ahli biologi dan tanaman obat menggunakan indeks Aiken’s V, serta uji coba pada 66 siswa sekolah menengah atas. Hasil validasi menunjukkan bahwa tiga belas aspek konten memenuhi kriteria validitas yang baik (V ? 0,76) pada tingkat kepercayaan 95%. Uji efektivitas menunjukkan peningkatan signifikan pada environmental knowledge, environmental values, dan environmental attitudes siswa (p < 0,001). Kelompok kontrol tidak menunjukkan peningkatan yang signifikan. Selain itu, e-module membantu siswa mengaitkan konsep Biologi dengan pemanfaatan sumber daya hayati secara berkelanjutan. Kebaruan penelitian terletak pada integrasi pengetahuan tanaman obat ke dalam e-module Biologi digital yang tervalidasi, secara khusus dirancang untuk mengembangkan berbagai dimensi literasi lingkungan. Temuan penelitian menunjukkan bahwa e-module berbasis tanaman obat yang tervalidasi efektif mendukung pengembangan literasi lingkungan sekaligus mendorong inovasi pembelajaran berbasis teknologi.
