Abstract
In the study, experimental studies comparing the effectiveness of different methods for astronomy subjects were examined. It is aimed to reveal how students are influencing their understanding of basic astronomy concepts, by studying quantitative perspectives from these studies. In this manner, it is aimed to examine by combining the effect sizes of the studies that demonstrate the effect of the experimental methods on the participants' academic achievements in astronomy subjects. Within the scope of the research, 39 articles published in the field of astronomy between 2000-2016 were reached at the national literature. Six studies were selected from these studies that met the inclusion criteria for meta-analysis. It was determined that the third one belongs to 2012 and the other three belong to 2014, and the majority of the studies were made in the seventh grade 'Solar System and Beyond: Spacecraft' unit and consisted of the seventh and eighth grades except one study. It was also determined that achievement test, conceptual understanding test, documents and semi-structured interviews were used as data collection tools. In the analysis of the data, it was seen that descriptive statistics were used in general, inferential analyzes were made and parametric tests were used. At the end of the analysis of the descriptive data, these studies were evaluated by meta-analysis. As a result of the analysis, the effect size was calculated as 0.816. It is understood that this value is at a high level. From this point of view, it has been found that different for astronomy are more effective than those used in the control group.
