The effect of research inquiry based education on scientific process skills: A national meta analysis study

In this study, it is aimed to determine the effect of Research Inquiry Based Teaching (RIBT) on students' Scientific Process Skills (SPS). The sample of the study consists of 35 studies at national level which examined the impact of RIBT on SPS between 2006-2018. While 29 of these were experimental control group studies examining the effect of RIBT on SPS, 6 were obtained from subgroups of these studies. In the determination of the sample, the coding form prepared by the researcher in accordance with the inclusion criteria was used. The studies included in the research were obtained by scanning YÖK-Tez, ULAKBİM and Google Scholar databases. Meta-analysis method was used in the study. CMA program (Comprehensive Meta Analysis) was used in the analysis of the data obtained and the overall effect size was calculated according to the random effects model. As a result of the study, according to the random effects model, the overall effect size of RIBT on SPS was found to be positive with 0.876 and medium level according to literature. This indicates that the RIBT applied to the experimental groups had a significant effect on SPS compared to the other methods applied to the control groups. In the light of the results obtained in the study, various suggestions were presented to teachers, program developers and researchers about the RIBT approach.
