Abstract

This activity aims to explore and improve the collaborative skills of students at SMA Kristen 1, Salatiga with class XII IPA students as participants. The data collection technique used a collaborative skills observation sheet with indicators 1) working productively; 2) being responsible; 3) respecting other students and; 4) compromising. The data analysis technique used the percentage of collaborative skills. In photosynthesis learning, students with collaborative skills in the exemplary category reached 14 people (19.4%), proficient 47 people (65.3%), basic 9 people (12.5%), and novice only 2 people (2.8%). In mitosis learning, students who had collaborative skills in the exemplary category were only 9 people (12.5%), proficient 52 people (72.2%), basic 8 people (11.1%), and novice only 3 people (4.2%). In the aspect of working productively in photosynthesis learning, the novice category reached 8 people (11.1%), while in mitosis learning the novice category was only 2 people (2.8%). In the aspect of being responsible for photosynthesis, the novice category reached 9 people (12.5%), while in mitosis learning, the novice category was only 4 people (5.6%). Furthermore, in photosynthesis learning in the aspect of flexibility and compromise, the novice category reached 8 people (11.1%), while in mitosis learning the novice category was only 7 people (9.7%). Based on these findings, it can be concluded that there has been an increase in the number of students who are increasingly skilled in collaborating with students.

Abstract

Although Problem-Based Learning (PBL) has been widely recognized for improving students' critical thinking skills, studies examining how Lesson Study (LS) strengthens the implementation of PBL, particularly in environmental change learning, remain limited. Therefore, this study aimed to identify the good practices of Lesson Study implementation and examine the effect of integrating Lesson Study into PBL on students' critical thinking skills. A mixed-methods approach was employed, combining qualitative and quantitative methods. Qualitative data were analyzed to identify the good practices of Lesson Study implementation, while quantitative data were collected using a quasi-experimental pretest–posttest control group design. The study involved two equivalent classes selected through a placement test, comprising 30 students in the experimental (PBL-LS) group and 30 students in the control (PBL) group. Lesson Study was implemented through four cycles consisting of the plan, do, and see stages. Quantitative data were analyzed using the Wilcoxon Signed-Rank Test and Mann–Whitney U Test. The results showed that Lesson Study generated good practices through improved lesson planning, more responsive instruction, and continuous reflection-based improvement. The PBL-LS model significantly improved students' critical thinking skills (p < 0.05), achieved a higher N-Gain score (0.63) than the PBL group, and showed significantly better critical thinking performance. These findings suggest that integrating Lesson Study into PBL strengthens instructional effectiveness and provides biology teachers with an effective approach to enhancing students' critical thinking skills in environmental change learning.
