Fitriani Laonu, A 202 22 016, Development of discovery learning-based LKPD to improve collaboration skills and critical thinking of Class VIII students of SMP Negeri 3 Bungku. Supriyatman and Darsikin.

This study aims to describe the feasibility of developing discovery learning-based LKPDs for class VIII students of SMPN 3 Bungku, and to produce LKPDs that can improve students' collaboration and critical thinking skills. This research uses a Research and Development (R&D) approach with the Four D (4D) development model, which involves the Define, Design, Develop, and Disseminate stages, adapted to the characteristics of the subject and development needs in the field. The research design used a nonequivalent pretest-posttest control group design with two classes: experimental and control, to assess the effectiveness of the LKPD development. The results showed that the discovery learning-based LKPD was very valid with an average of 92.31%. The effectiveness was obtained from the analysis of critical thinking skills using pretest and posttest questions, in the experimental class an increase of 30.50% was obtained while in the control class an increase of
28.34% was obtained. Effectiveness was also obtained from collaboration skills using observation sheets in the experimental class, an increase of 14% was obtained while in the control class an increase of only 5% was obtained. Practicality is obtained from the results of the teacher's response which states that the LKPD is practical to use. Then the effect size test obtained a result of 0.80 with a very large effect. So it is recommended to be able to apply discovery learning-based LKPD more widely in an effort to improve learning collaboration skills and critical thinking at the junior high school level.
