Synthesis of Research on Science Learning Management Affecting Problem Solving Skills: Meta-Analysis

Abstract

The rapidly changing world of the 21st century is complex and unpredictable.
The researcher aimed to study the findings from a meta-analysis of 42 research
studies related to the learning management of science that affects problem-solving
skills during 2012–2022 from a database in Thailand called ThaiLIS. The findings
revealed the variables that cause different mean effect sizes and the influence of
research quality on the effect size. The instruments of this research were the
research quality assessment form and the research characteristics assessment form.
Statistics for data analysis were mean, standard deviation, one-way analysis of
variance, and multiple regression analysis. The directional research hypothesis,
multi-stage sampling, randomized control group post-test only design, PBL, and
Weir's solution theory were discovered in the study to be the variables that caused
the mean effect sizes to differ at the statistical significance level of .05. In
addition, research quality had a positive influence on the effect size. The findings
of this study will be useful to teachers who want to provide learning management
of science that helps students develop problem-solving skills. This will develop
skills more effective than traditional teaching.
