Pengembangan Lembar Kerja Interaktif Berbasis Literasi Sains untuk Melatih Kemampuan Berpikir Kritis Peserta Didik Materi Fotosintesis
Abstract
Interactive Student Worksheets (LKPD) based on scientific literacy are an effective alternative learning method for training junior high school students critical thinking skills. This research focuses on developing interactive LKPD based on scientific literacy on photosynthesis material. The aims of this research are (1) to analyze the validity and effectiveness of interactive LKPD based on scientific literacy in training students' critical thinking skills, and (2) to analyze the results of students' critical thinking abilities while using interactive LKPD based on scientific literacy. The research method used is development research with the ADDIE model, which consists of analysis, design, development, implementation and evaluation. The subjects of this research were 30 students in class VII-6 of SMP Negeri 3 Lubuk Pakam. Research data was obtained from validation results by validators, data from critical thinking skills based on observations by observers and data from pretest and posttest results. The research results show that (1) the interactive LKPD developed has very high validity, both in terms of media at 95.24% and terms of material at 85.81%. Interactive LKPD is categorized as effective in training critical thinking skills with a percentage of 63%. (2) The pretest and posttest results show a significant difference with an N-gain value of 0.6, indicating a moderate increase, with classical learning completeness reaching 93%. Thus, this scientific literacy-based interactive worksheet on photosynthesis has proven to be valid and effective in training junior high school students critical thinking skills.
