Abstract

This study aims to design and produce Student Worksheets (LKPD) based on the Scientific Approach for animalia material for 10th-grade students in SMA Yayasan Perguruan Utama Medan. The research used a research and development methodology. The design of the Scientific Approach-based LKPD was carried out using the 4-D development model, namely Define, Design, Development, and Disseminate. The research results show that the developed LKPD based on the scientific approach received a "very feasible" assessment from learning experts at 97.7%, from subject matter experts at 85.71%, and from design experts at 97.9%. Additionally, subject teachers also assessed it as "very feasible" at 96.87%, and students provided a "positive" assessment with a score of 95.96%. The effectiveness test of the developed LKPD based on the scientific approach showed an N-Gain value of 0.64 with a "moderate" criterion. The results of this study indicate that the LKPD for animalia material can be used in the learning process.

Abstract

This research aims to develop audiovisual-based learning media on the topic of the immune system in class XI of SMA Negeri 12 Medan during the academic year 2021/2022. The method used in this study is research and development. The research subjects consist of Subject Matter Experts, Learning Media Experts, Biology Subject Teachers, and students of class XI MIA at SMA Negeri 12 Medan. Data collection was conducted through instruments such as expert validation assessment sheets, teacher assessments, and student responses. The development of learning media was carried out using the 4D instructional development model (Define, Design, Development, and Disseminate). Each stage of this model underwent revisions to produce high-quality audiovisual learning media products. The results of the study showed that the assessment by subject matter experts obtained a percentage of 100% (Highly Suitable), the assessment by learning media experts obtained a percentage of 82.81% (Suitable), and the assessment by the biology subject teacher obtained a percentage of 100% (Very Good). The students' feedback and responses to the learning media also obtained a percentage of 81.66% (Very Good). The results of the comprehension test on the learning media for the students, based on the pretest scores, showed an average of 49.75 (Low), while the posttest results showed an average of 76.96 (High). Thus, it can be concluded that the audiovisual learning media on the topic of the immune system meet the criteria of being "Highly Suitable" and fulfill the requirements in the biology learning process.
