A META-ANALYSIS APPROACH TO MEASURE THE IMPACT OF PROJECT BASED LEARNING OUTCOME

The importance of a thorough analysis of previous research regarding the influence of the project based learning model on students' learning outcomes over the last ten years in order to have a clearer picture of what learning abilities are suitable to be applied in science lessons. The aim of this research is to find out how much influence the project based learning model has on student learning outcomes. The ES studied is the result of several studies that have been carried out. This research uses meta-analysis, namely reviewing similar research, which is summarized from various research results quantitatively by looking for EF values. The study journals used were international journals indexed by Scopus in the last 10 years, totaling 10 journals. Data obtained from the research instrument was analyzed using the effect size formula. The average ES value obtained was 0.78 which is in the medium category. This shows that the use of the project based learning model in the learning process can improve student learning outcomes.
