Abstract

Learning activities always develop following the needs of the times. Some skills, such as critical thinking, need to be possessed by 21st-century individuals. This study aims to analyze critical thinking skills of students who learn collaboratively based on the Science, Technology, Society, and Environment (STSE) learning approach. A posttest nonequivalent control group design was adopted in this research. Through cluster random sampling, 68 students at one public senior high school in Sleman Yogyakarta, participated as a research sample, which divided into 2 classes. Students in experimental class (N=35) has been learn about electrolyte nonelectrolyte topic through collaborative learning based STSE approach. While, the other students in the control class (N=34), taught by student center learning. In the fifth meetings, students’ critical thinking skill was measured as a research data through an essay questions instruments that has been empirically validated. Afterwards, research data were analyzed using independent sample t-test. Moreover, the p-value shown in the analysis results was 0.009. This result is sufficient to indicate that at the 95% confidence level there is a significant difference in students' critical thinking skill between the experimental class and the control class. The partial eta squared value shows that STSE learning approach has an effect to fostering students’ critical thinking in learning chemistry, in this research there was 9.8% effect that can be highlighted.

Abstract

Kegiatan pengabdian pada masyarakat (PPM) bertujuan untuk: (1) meningkatkan pengetahuan masyarakat Seyegan tentang bahan dan manfaat sabun scrub alami dari ampas kopi, (2) meningkatkan ketrampilan masyarakat dalam pemanfaatan teknologi tepat guna pembuatan sabun scrub alami dari ampas kopi, dan (3) memotivasi minat wirausaha masyarakat Seyegan. Kegiatan PPM ini bersifat pelatihan dan dilaksanakan dengan metode ceramah, diskusi dan praktik. Melalui kegiatan tersebut, peserta telah mendapat materi tentang: (1) pembuatan sabun scrub alami dari ampas kopi, (2) kandungan dan manfaat kopi untuk kesehatan kulit, (3) sabun yang aman untuk kesehatan kulit, (4) peluang wirausaha sabun kopi, dan (5) pewarna dan pewangi yang bersifat skin grade. Peserta yang telah mengikuti pelatihan ini berjumlah 11 orang yang merupakan masyarakat di daerah Padukuhan Kamal Wetan, Mangsel VII, Margomulyo, Seyegan. Evaluasi kegiatan PPM dilakukan dalam 2 tahapan, yaitu evaluasi proses melalui observasi selama kegiatan PPM dan evaluasi hasil melalui produk sabun yang dihasilkan serta isian angket kegiatan PPM. Melalui kegiatan ini, dapat disimpulkan bahwa peserta pelatihan telah memperoleh (1) manfaat tentang bahan dan sabun alami dari ampas kopi, (2) pengetahuan dan keterampilan dalam pemanfaatan teknologi tepat guna pembuatan sabun scrub alami dari ampas kopi, namun motivasi dan minat wirausaha peserta pelatihan untuk membuat sabun scrub ampas kopi masih perlu untuk ditingkatkan.

Abstract

Critical thinking is the main skill for connecting relationships between chemical science concepts in a coherent environment. Therefore, a learning and evaluation method is needed to help students master the meaning of chemistry to environmental phenomena. The Fundamental of Analytical Chemistry course invites students to study the technique of determining the concentration of a compound. This is relevant to improve their critical thinking skills. This study aims to analyze the effect of the implementation of Technology-based Authentic Assessment (TbAA) on students' critical thinking skills in Fundamental of Analytical Chemistry course. Designed as a pre-experimental, one group pretest-posttest study was applied. A total of 26 undergraduate Chemistry students were included as samples through purposive sampling. TbAA was held for 7 meetings, then critical thinking skills were assessed through essay instruments covering aspects of interpretation, analysis, evaluation, inference. The validity test was carried out theoretically by 2 learning chemists on 4 critical thinking questions that had been developed. After the data was obtained, descriptive statistics and the Wilcoxon test were carried out to answer the research objectives. Based on the results of the analysis, there is a significant difference in students' critical thinking skills after the application of TbAA.
