The Effect of RICOSRE on Students' Critical Thinking Skills in Biology

摘要

Critical thinking is one of the 21~(st)-century skills that need to be promoted in learners. Students' critical thinking can be facilitated through the implementation of an appropriate learning model. This study aimed to investigate the effect of RICOSRE learning model on students' critical thinking skills. This study involved 99 students from Public Senior High School Number 1 (SMAN 1) Turen in Malang, Indonesia, and employed a pretest post-test non-equivalent control group design. An ANACOVA analysis at a significance level of 0.5% (p < 0.05) and LSD test 5% were performed to test the hypothesis. The results showed that the learning model affected the students' critical thinking skills. The students' critical thinking skills have been improved by 79.91 % through RICOSRE, 19.00% through PBL, and 5.15% through a conventional learning model. Since RICOSRE has the most significant impact on students' critical thinking skills, it is highly recommended for biology learning.
