To date, researchers have frequently investigated students’ attitudes toward courses supported by problem-based learning. Thus, there are several studies with different results in the literature. Therefore, a clear conclusion about the subject cannot be obtained. As a result, it is necessary to combine and interpret the findings of these studies through a meta-analysis method.

Material and methods:
The meta-analysis method aims to combine different results of similar and independent studies through statistical techniques. Research findings of 47 studies that meet the criteria for meta-analysis are included in the meta-analysis of the study to determine the effects of problem-based learning on students’ attitudes as compared to traditional teaching.

As a result of the analysis, it has been found that problem-based learning has a positive effect on students’ attitudes; however, the effect size is low (g = 0.44). Some mediator variables are as follows: the status of a study, application time, education levels, scientific field of application, and sample size.

Consequently, problem-based learning is effective in helping students gain a positive attitude toward courses. In addition, mediator variables do not affect students’ attitudes toward courses in problem-based learning applications.
