Abstract

Students’ understanding of synthetic polymer topics was still low due to the abstract nature of the material and the lack of supporting teaching resources. This study focused on developing a project-integrated chemistry e-module on the topic, aiming to produce a valid, practical, and effective learning resource. The development model used was ADDIE, which consisted of analysis, design, development, implementation, and evaluation stages. The validation results showed that the e-module was very feasible in terms of content with a score of 94% and feasible in terms of media with a score of 73%. After revision, the media score increased to 96% with a very feasible category. A small-scale trial involving 12 students of grade XII in the 2024/2025 academic year obtained very positive responses with an average of 94%. The implementation with 27 students of grade XI IPA 1 MAN 1 Bengkulu through pre-test and post-test resulted in an N-Gain score of 0.74 (high category). These findings proved that the developed e-module was effective in improving students’ understanding and was feasible to be used as an alternative chemistry learning resource on synthetic polymers.

Abstract

This study aims to identify the characteristics of a biochemistry practicum program on DNA isolation from local Bengkulu citrus, developed to enhance students’ systems thinking skills. A descriptive analysis was conducted through the review of course outlines, practicum implementation documents, student learning modules, and worksheets, as well as observations of practicum sessions and evaluations of students’ learning experiences. The practicum program was implemented with 37 students enrolled in a Biochemistry course at a public university in Bandung. The findings reveal three key characteristics. First, the practicum was restructured from a textbook-based model into a contextual practicum using local Bengkulu citrus as an authentic sample. Second, the practicum employed modern laboratory tools—including microtubes, micropipettes, vortex mixers, and centrifuges—which improved the accuracy of DNA isolation and visualization. Third, the activity design integrated systems thinking skills through component analysis, process interrelationships, and result interpretation. Overall, the developed practicum is contextual, modern, and systems-oriented, enhancing both the relevance and quality of students’ laboratory learning experiences

Abstract

This study aims to produce chemistry teaching materials for Thermochemistry that contain Islamic values. The development of teaching materials was carried out using the Four Steps Teaching Material Development (4STMD) method. This study focuses on the Design and Development stages. The results of the teaching material development at the Design stage produce a teaching material design. The Development stage in developing teaching materials uses the Four Steps Teaching Material Development (4STMD) method, which consists of four stages: selection, structuring, characterization, and didactic reduction. The first stage begins with a selection process that produces 11 competency achievement indicators and 18 concept labels that must be developed. In the source selection step, 2 international textbooks and 1 high school textbook were used. The results obtained at the structuring stage are concept maps; macro structures and three levels of representation that are in accordance with the context of daily life and Islamic values. Characterization was carried out by 30 high school students and it was found that 4 texts were included in the difficult to understand category so that didactic reduction was carried out. The results of the didactic reduction stage were texts that were difficult for students to understand were given treatment with a type of didactic reduction back to the qualitative and neglect stages. The conclusion obtained from the results of this development research was the formation of chemistry teaching materials for Thermochemistry material that integrated Islamic values.
