Pengembangan LKPD Berbasis Lingkungan untuk Meningkatkan Scientific Creativity pada Pembelajaran IPA Siswa SMP

Abstract

Science learning at the junior high school level plays an important role in developing students’ scientific creativity. However, preliminary observations at SMP Negeri 1 Arjasa indicated that students’ scientific creativity was still low due to teacher-centered instruction and the limited use of the environment as a learning resource. This study aimed to develop an environment-based Student Worksheet (LKPD) on the topic of substances and their changes and to examine its validity, practicality, and effectiveness in improving students’ scientific creativity. This research employed a Research and Development (R&D) method using the ADDIE model, which consists of analysis, design, development, implementation, and evaluation stages. The research subjects included one science teacher and 30 seventh-grade students of class VII F at SMP Negeri 1 Arjasa. The research instruments comprised validation sheets, learning implementation observation sheets, scientific creativity pretest and posttest, and student response questionnaires. Data were analyzed using descriptive quantitative techniques through percentage analysis and N-gain calculation. The results showed that the developed environment-based LKPD achieved a validity level of 89%, categorized as very valid. The practicality of the LKPD was indicated by an average learning implementation score of 82%, categorized as very practical. The effectiveness of the LKPD was demonstrated by an increase in students’ scientific creativity with an N-gain score of 0.37, categorized as moderate. Therefore, the environment based LKPD is feasible and effective for use in junior high school science learning
