Abstract

Penelitian dan pengembangan ini bertujuan untuk (1) mengembangkan bahan ajar yang valid dan layak untuk meningkatkan self regulation mahasiswa, (2) mengetahui efektivitas bahan ajar yang dihasilkan dalam meningkatkan self regulation mahasiswa. Rancangan penelitian dan pengembangan ini mengacu pada model penelitian dan pengembangan Lee & Owens. Hasil pengembangan adalah bahan ajar blended learning pada materi larutan elektrolit non-elektrolit dan sifat koligatif larutan, pada mata kuliah Kimia Dasar II yang disajikan secara online pada laman Sipejar serta bahan ajar offline berupa Lembar Kerja Mahasiswa. Hasil uji validitas dan kelayakan menunjukkan bahwa bahan ajar hasil pengembangan valid dan layak untuk diaplikasikan dalam pembelajaran dengan tingkat kelayakan dari ahli dan dari mahasiswa sebesar 79 persen. Berdasarkan hasil uji efektivitas yang telah dilakukan melalui kegiatan pembelajaran, dinyatakan bahwa hasil pengembangan efektif diaplikasikan pada pokok bahasan larutan elektrolit non-elektrolit dan sifat koligatif larutan. Peningkatan self regulation mahasiswa ditunjukkan dengan skor n-gain terhadap hasil angket Self Regulated Learning sebelum dan sesudah pembelajaran. skor n-gain tertinggi diperoleh yaitu sebesar 0,852 dan skor n-gain terendah diperoleh sebesar 0,027. Sehingga dapat diketahui bahwa 4 mahasiswa mengalami peningkatan self regulation yang tinggi, 13 mahasiswa mengalami peningkatan self regulation sedang dan 15 mahasiswa mengalami peningkatan SRL rendah.

Abstract

This study aims to analyze the effectiveness of cognitive load reduction strategies in improving 3T students' understanding of the concept of stoichiometry. Students from 3T areas often have difficulty in understanding chemical concepts due to limited access to quality learning resources and challenges in numeracy. Therefore, this study applies a cognitive load reduction strategy that includes material segmentation, scaffolding, concept visualization, and the use of analogies and real contexts in stoichiometry learning. The research method used is a quasi-experiment with a pretest-posttest control group design. The subjects of the study consisted of 3T students who were divided into experimental groups and control groups. Data were collected through a stoichiometry understanding test, a cognitive load questionnaire, and in-depth interviews. The results of the analysis showed that the experimental group experienced a significant increase in posttest scores compared to the control group. In addition, students in the experimental group showed a higher level of understanding retention and a reduction in misconceptions after the implementation of the cognitive load reduction strategy. This study provides evidence that the cognitive load reduction strategy can improve the effectiveness of stoichiometry learning by reducing students' cognitive load. The implications of this study suggest that this approach can be applied more widely in chemistry teaching to improve students' conceptual understanding and numeracy skills. Thus, the results of this study can be the basis for the development of more innovative and adaptive teaching methods for students with diverse educational backgrounds.

Abstract

This study aims to examine the effectiveness of the dual-processing method in improving the proportional thinking skills of 3T students in chemistry learning, especially in dealing with numeracy barriers. The dual-processing method refers to a cognitive theory that combines intuitive thinking (System 1) and analytical thinking (System 2) to improve students' conceptual understanding and numeracy skills. This study used a quantitative and qualitative approach with a pre-test and post-test experimental design and observation of student participation during the learning process. The results showed that after the dual-processing method intervention, there was a significant increase in students' numeracy skills, with an average post-test score increasing by 33.5 points compared to the pre-test. In addition, this method also helps reduce academic anxiety and increase students' confidence in solving numeracy problems. Classroom observations showed that students were more active in discussions and more reflective in solving chemistry problems than before the intervention. The dual-processing method has been proven effective in improving 3T students' numeracy understanding and overcoming proportional thinking barriers in chemistry learning. Therefore, the integration of this method into the higher education curriculum is recommended to improve students' critical and analytical thinking skills in numeracy-based disciplines.

Abstract

Pelatihan pembuatan hand sanitizer bagi calon mahasiswa dari wilayah 3T (Terdepan, Terluar, dan Tertinggal) bertujuan untuk meningkatkan pemahaman teoretis dan keterampilan praktis mereka dalam bidang kimia dasar. Kegiatan ini melibatkan 42 peserta dari Papua, dengan pendekatan partisipatif yang terdiri dari sesi teoretis, praktik langsung, dan diskusi kelompok. Hasil pelatihan menunjukkan bahwa 90% peserta berhasil memahami materi yang disampaikan, dan 85% produk yang dihasilkan memenuhi standar WHO. Selain meningkatkan keterampilan teknis, pelatihan ini juga memberikan dampak positif pada pengembangan sikap disiplin, tanggung jawab, dan kemampuan kerja sama peserta. Evaluasi umpan balik menunjukkan tingkat kepuasan yang tinggi terhadap metode dan materi pelatihan, meskipun ada usulan untuk memperpanjang durasi kegiatan dan menambah variasi materi. Pelatihan ini memberikan pengalaman berharga bagi peserta dan menjadi model potensial untuk program serupa di masa depan, guna mendukung peningkatan kualitas pendidikan dan pengembangan kapasitas sumber daya manusia di wilayah 3T.
