Developing LKPD Based on Discovery Learning to Improve Collaboration and Critical Thinking Skills in Class VIII Students at Junior High School

Key Points

The discovery learning-based LKPD significantly enhanced collaboration skills in students.
Students exhibited an increase of 30.50% in critical thinking skills in the experimental group compared to the control group.
The R&D approach utilized the 4D development model to assess the LKPD's feasibility and effectiveness.
With an effect size of 0.80, the discovery learning LKPD demonstrates a very large impact on learning outcomes.

Abstract

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 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 skill,s and critical thinking at the junior high school level.
