It is known that teaching with Concept Map Technique is mostly used in academic studies that investigate the success of differences in the control and experimental groups of experimental studies. Meta-analysis summarizes the results of various studies in the fields of sciences and aims at reaching a common judgment by combining the used conclusions. The purpose of this study is to obtain a general opinion about the effectiveness of taught courses which are taught by using concept map technique in our country by using meta-analysis method. This research has also used the meta-analytical screening method which allows to combine the results of similar studies and to calculate common effect sizes. The most important results among others in this research are that the use of concept map technique has an important level of superiority compared to other techniques.
