Problem Statement: A number of recent studies on constructivism that have been conducted separately (independently) have arrived at very different results. Throughout the ten-year period in which the constructivist approach has been applied, there have been studies that have researched the effect of the newly-introduced approach on student attitudes towards lessons. In such situations, there exists a pressing need to look at all previous studies so that new studies approach subjects from a more developed and advanced perspective and arrive at more scientifically reliable results. For this reason, there is a critical need for a more comprehensive and detailed approach to the subject under research so as to interpret, contrast, and provide better access for researchers with regard to the studies already conducted on this topic. Meta-analysis has been accepted as a method that helps in this aim.
