Pengembangan LKPD Berbasis Engineering Design Process (EDP) untuk Meningkatkan Keterampilan Kolaborasi Siswa pada Pembelajaran IPA SMP

Abstract

This study aims to develop LKPD based on Engineering Design Process (EDP) to improve students collaboration skills of science learning in junior high school. This study use the ADDIE development model consisting of 5 stages, namely analysis, design, development, implementation, and evaluation. The subjects of the trial in this study were students of class VII F MTs Negeri 2 Jember in the 2024/2025 Academic Year in the odd semester. Data collection instruments were carried out using validation sheets, activity implementation sheets, collaboration skills observation sheets, student response questionnaire sheets, interviews, and documentation. Product validation was carried out by 3 validators, product practicality testing was carried out using learning implementation observations, and effectiveness testing was carried out using collaboration skills observation sheets and student response questionnaires. The results of the validation test obtained a score of 87.4% with a very valid category. The results of the practicality test obtained a score of 89.6% with a very practical category. The results of the effectiveness test obtained an N-Gain score of the first collaboration skill of 0.29 with a low category and an N-Gain score of the first collaboration skill of 0.47 with a medium category with an N-Gain difference of 0.18, and an overall student response score of 88.3% with a very effective category. Based on the results of the data analysis obtained, the Engineering Design Process-based LKPD is said to be very valid, very practical, and quite effective in improving students' collaboration skills so that it can be used in science learning.
