Abstract

Kemampuan meneliti dan publikasi masih menjadi masalah bagi sebagian besar guru. Mengacu pada permasalahan tersebut, Program Doktor Pendidikan Sains Pascasarjana Universitas Negeri Semarang bersama MKKS Wilayah X Banyumas telah menyelenggarakan bimbingan teknis yang bertujuan untuk (1) meningkatkan kemampuan guru dalam merencanakan, melaksanakan, dan melaporkan kegiatan penelitian. (2) meningkatkan kemampuan guru dalam menyusun artikel ilmiah hasil penelitian untuk dipublikasikan dalam jurnal ilmiah. Kegiatan dilakukan secara online dalam 4 tahap mulai 10 Juni 2021 hingga 6 November 2021. Sebanyak 110 guru SMA se-Banyumas Raya. Metode yang digunakan dalam kegiatan ini adalah prinsip learning by doing, dilakukan secara klasikal melalui zoom cloud meeting untuk penyampaian materi secara teori dan pendampingan individu melalui WhatsApp Group dan email. Luaran dari program ini berupa proposal penelitian, dan artikel ilmiah untuk dipublikasikan. Antusiasme peserta dalam menyusun proposal penelitian dan menulis artikel untuk publikasi sangat tinggi dan mereka menginginkan pendampingan yang berkelanjutan untuk sukses melaksanakan penelitian dan mempublikasikan artikel ilmiah.

Abstract

Critical thinking skills are essential 21st-century skills that need to be developed, including in complex chemistry equilibrium material that requires in-depth analysis. Context-based learning and problem solving, such as a combination of Problem Based Learning (PBL) and Contextual Teaching and Learning (CTL), are expected to combine the strengths of both in improving critical thinking skills. This study aims to analyze the effect of applying PBL-CTL on critical thinking skills and compare it with non-CTL PBL. The type of research is a quasi-experiment – post-test non-equivalent control group design. The sample selection was conducted using a combination of purposive sampling and cluster random sampling after testing the normality and equality of variance in the population. This study was conducted by comparing two sample groups. The experimental group applied PBL-CTL, while the control group used PBL. Data were obtained from the completion of worksheets, post-tests, and observations. The Mann-Whitney U test results showed significant differences in critical thinking skills (p=0.010) and knowledge (p=0.038), with the experimental group having a higher mean rank. The effect size test indicated a moderate effect on critical thinking skills (r=0.304) and knowledge (r=0.244). These findings prove that PBL-CTL has a significant moderate effect on improving students' critical thinking skills and knowledge in chemical equilibrium material, with a greater effect on critical thinking skills. In addition, students in the PBL-CTL group consistently achieved higher scores on critical thinking indicators and mastery of material compared to the non-CTL PBL group.
