Pengembangan LKPD Berbasis Learning Cycle 5E Berbantuan PhET Simulation untuk Meningkatkan Kemampuan Penalaran Ilmiah bagi Siswa SMP

Abstract

Rapid developments in Science and Technology (IPTEK) have accelerated the pace of globalization. As a result, competition in various aspects of life, including in the field of education, is becoming increasingly intense. One of the skills that is key in dealing with this phenomenon is students' scientific reasoning abilities. This ability is considered essential in the 21st century era. However, the scientific reasoning abilities of Indonesian students are still relatively low. This research aims to develop LKPD based on Learning Cycle 5E assisted by PhET Simulation that is valid, practical and effective. The type of research developed is Research and Development (R&D) using the ADDIE model. The research subjects were students of class IX semester 1 at SMPN 1 Jenggawah. The research data was analyzed based on several criteria. The results of the LKPD development obtained validity test results with a score of 91% (very valid). The practicality test results obtained an average score of 92.5% (practical). The results of the effectiveness test obtained an average N-Gain of 0.67 (medium). Based on the research findings, LKPD based on Learning Cycle 5E assisted by PhET Simulation can provide innovation in learning resources as an alternative to improve the scientific reasoning abilities of junior high school students.
