Meta-analysis Studies of Environmental Education in Iran from 2016-2020

According to the increasing amount of research in the field of environmental education, in this article, we tried to collect the preliminary results of research and combine these results to express a consistent view of the effectiveness of the environmental education meta-analytical research method. Its statistical population is 25,003 postgraduate dissertations and scientific research articles. The selected statistical sample related to environmental education based on curriculum elements is 138 articles in different years, of which 57 articles were selected in 2016-2020. Excel software was used to report and record the information required to provide the required information from the worksheet designed by the researcher. The reliability of the research was obtained through the contrast of research findings. The analysis of the findings is based on Roberts' six-step pattern, which is consistent with the elements of the curriculum used, using open and axial coding methods. Based on the findings, because environmental education develops awareness and increases environmental sensitivity, it is the most important method in educating individuals in identifying and dealing with environmental problems. Environmental Education is influenced by these seven factors: Assessment, education method, formal education, informal education, public education, and lifelong education and sustainable development. The results in most of the studies suggest the effectiveness of informal education over formal education. In recent years, environmental education has been considered more important in all cases and for all groups. So, environmental education is essential to society in general.
