META ANALISIS: PENGARUH MODEL PEMBELAJARAN PROBLEM BASED LEARNING TERHADAP KETERAMPILAN ABAD KE-21 DALAM PEMBELAJARAN BIOLOGI

Abstract

Previous research data on problem-based learning (PBL) models are widely available in scientific publications, but there has been no comprehensive study of the effectiveness of the PBL learning models on Biology students’ 21st century skills. This purpose of this study was to determine the overall effect of the PBL learning models on 21st century skills in Biology learning using the meta-analysis method. The study analyzed 30 articles that met the criteria from 150 scientific publication articles in 2013-2023 at the high school and junior high school levels. The data analysis technique employed effect size calculations. The results showed that the application of the PBL learning model had a major influence on 21st century skills in Biology learning (effect size= 1,23). Based on the level of education, it has a large effect, namely high school (1,22) and junior high school (1,30). Based on the dependent variables, the research provides a large effect, namely critical thinking (1,04), problem-solving (1,37), creative thinking (1,12), collaboration (2,56), and communication (1,03). Thus, the PBL learning model is more effectively applied in learning Biology compared to conventional learning models, especially in improving students' 21st century skills.
