The Influence of Problem-Based Learning Model with the Integration of Socio Scientific Issues on Students' Problem-Solving Skills and Mastery of Biology Concepts in High School

Problem solving is a skill that every student must have in facing the challenges of learning and everyday life. However, many students still have difficulty in developing skills due to one-way learning methods that focus on memorization. Concept mastery is the ability of students to understand, connect, and apply knowledge in depth in various contexts. Concept mastery can be improved by using the Problem Based Learning model that focuses on providing real problems at the center of learning. One of them is the Socio Scientific Issue approach which is integrated into the Problem Based Learning model. The purpose of this study was to determine the effect of implementing the Problem Based Learning model with Socio Scientific Issue integration on problem solving skills and mastery of biology concepts of high school students. The type of research used was a quasi-experiment conducted at SMAN Mumbulsari. The research sample used class X students of SMAN Mumbulsari consisting of one experimental class and one control class. The data analysis techniques used were normality test, homogeneity test, ANACOVA hypothesis test and assessment of the implementation of learning syntax. The data obtained were obtained from the results of the pretest and posttest. The results of the study were obtained based on the results of the assessment of the syntax implementation sheet of learning showing that all steps were implemented with a percentage of 100%. The results of the ANACOVA test for both students' problem-solving skills and mastery of biology concepts of high school students obtained a significance value (Sig.) <0.05. This indicates an influence on the learning model applied, namely the Problem Based Learning model with the integration of Socio Scientific Issues on problem-solving skills and mastery of biology concepts of high school students.
