Abstract

The integration of 21st-century learning and generic science skills (GSS) is critical in developing students' higher-order thinking skills (HOTS), especially in chemistry education. This quasi-experimental study aimed to analyze the effects of implementing four GSS-integrated digital learning models (PjBL-GSS, PBL-GSS, IBL-GSS, and DL-GSS) and students’ initial abilities on their HOTS performance. A total of 397 students participated, grouped by initial ability levels and assigned to different learning models. Data were collected using validated instruments including scholastic tests and HOTS assessments, and analyzed using descriptive statistics and two-way ANOVA. The results showed significant effects of both initial abilities and learning models on HOTS, with IBL-GSS being the most effective, especially for high-ability students. Moreover, significant interactions were found between initial ability and the type of model used. The study suggests that selecting appropriate digital learning models based on students' prior knowledge is essential to foster optimal HOTS outcomes. Teachers are encouraged to align instructional design with both GSS indicators and students’ learning readiness.

Abstract

Andaliman (Zanthoxylum acanthopodium DC) adalah salah satu tumbuhan yang mengandung senyawa kimia penting yang dapat dimanfaatkan dalam kehidupan sehari-hari, namun pemanfaatannya masih sangat sedikit. Tujuan penelitian ini adalah untuk mengekstrak buah andaliman yang berfungsi sebagai antioksidan alami pada minyak sawit, yang berfungsi untuk meningkatkan kualitas minyak sawit. Pada penelitian ini dilakukan analisis kualitas minyak melalui penentuan bilangan peroksida minyak, bilangan iodin minyak dan asam lemak bebas dengan penambahan ekstrak buah andaliman dan tanpa penambahan ekstrak buah andaliman dengan variasi lama penyimpanan dan konsentrasi. Hasil penelitian ini menunjukkan bahwa semakin besar konsentrasi ekstrak buah andaliman, semakin kecil bilangan peroksida minyak, semakin besar bilangan iodin minyak, dan semakin kecil asam lemak bebas minyak. Hasil analisis disimpulkan bahwa waktu inkubasi dan konsentrasi berpengaruh signifikan terhadap bilangan peroksida, bilangan iodin dan asam lemak bebas minyak. Konsentrasi secara parsial berpengaruh terhadap ketiga parameter uji, sedangkan waktu tidak berpengaruh secara parsial.http://dx.doi.org/10.23960/aec.v5.i2.2020.p155-168

Abstract

Acid-base learning in high school still tends to be teacher-centered, resulting in low student activity and learning outcomes. This study aims to improve student activity and learning outcomes through the application of the Problem Based Learning (PBL) model assisted by worksheets (LKPD). The study used a quasi-experimental approach with a pretest-posttest control group design. Sixty-four eleventh-grade students were divided into two groups: an experimental class with problem based learning and a control class with direct instruction. The results showed that student learning activities in the PBL class were higher than in the control class. Student learning outcomes in the PBL class also improved significantly compared to the control class. Thus, the PBL model assisted by worksheets (LKPD) proved more effective in improving student activity and learning outcomes in acid-base material and encouraging more student-centered learning.

Abstract

Advances in chemistry during the Fourth Industrial Revolution demand learning that integrates concept mastery with 21st-century skills, yet current materials rarely combine local wisdom and digital technology. This study aimed to develop a chromatography textbook based on Project-Based Learning (PjBL), using an ethnoscience approach and Augmented Reality (AR), suitable for learning. The Research and Development (R&D) method, using the 4D model (Define, Design, Develop, Disseminate), was employed. The pilot study involved 20 Chemistry Education students, with expert validation sheets and student response questionnaires as instruments. The results of the expert validation indicated that this textbook is highly suitable, with an average content suitability percentage of 93.75%, graphic suitability of 93.75%, presentation suitability of 94.84%, and linguistic suitability of 100%. A pilot test conducted on a small group revealed highly positive student responses, with an average score of 3.88 (97.02%). These findings imply that integrating PjBL, ethnoscience, and AR can effectively support contextual, student-centered, and technology-enhanced chemistry learning. In practice, this approach can serve as a model for developing innovative instructional materials for other chemistry topics and for supporting curriculum transformation toward 21st-century skills.
