META ANALISIS EFEKTIFITAS PROBLEM BASED LEARNING DAN PROBLEM SOLVING DITINJAU DARI KEMAMPUAN BERPIKIR KRITIS SISWA SEKOLAH DASAR

Abstract

Abstract: Meta Analysis of the Effectivenecc of Problem Based Learning and Problem Solving in terms of Critical Thinking Ability of Elementary School Students. In quantitative research, Meta Analysis aims to determine whether the Problem Based Learning and Problem Solving learning model has a high influence on improving critical thingking skills in elementary school students. the techniquenused used is the\xa0 Effect Size technique analysis with the Effect Size formula. The instrument used was a worksheet instrument for coding the result of scientific publications that were searched through the internrt. The variables studied to obtain information about the magnitude of the effect of thus Effect Size are the Problem Based Learning and Problem Solving learning models as independent variables, and critical thingking skills as the dependent variable. From the results of the research the has been done, it shows that the measurement results of critical thingking skills in learning using the Problem Solving learning model are significantly higher than Problem Based Learning , meaning that the Problem Solving learning model is more effective in increasing the critical thingking skills of elementary school student. Judging from the Ancova test, the average value of Experiment 2 in the Problem Solving learning model is 83.3000 higher than the Problem Based Learning model of 76.0420. based on the results of the calculation of the hypothesis test using the Ancova test using Univariate which shows that the significance value is 0,009, which means less than 0,05 (0,009 F table is 11,311 with a significance of 0,009 F tabel yaitu 11,311 dengan signifikansi 0,009 < 0,05 yang menunjukan bahwa Ho ditolak dan Ha diterima. Dari hasil uji ini menunjukan bahwa Effect Size model pembelajaran Problem Solving lebih besar secara signifikan dibandingkan dengan Problem Based Learning ditinjau dari kemampuan berpikir kritis siswa sekolah dasar. Kata Kunci: Meta Analisis, Problem Based Learning , Problem Solving , Keterampilan Berpikir Kritis.
