Efficiency of using Stem Case-Based learning for teaching biology

The article discusses the implementation of integrated STEM learning - based on Case-Based Learning when teaching section "Laws Inheritance and Variation" in biology distance learning. aim study is to investigate effectiveness education. involved four groups 9th grade schoolchildren. selected classes were randomly divided into experimental control ensure validity this study. To methodology, results obtained compared by means final assessment for sections groups. 1 group which was applied (CBL), 2 group. research are analyzed using Student's t-test. Meanwhile, an efficacy CBL as a key factor student satisfaction, found that half students surveyed gave positive feedback favor learning, 20% participants chose both methods be effective Based study, it can said use online classroom has achievement.
