Investigation of the effectiveness of activities in out of school learning environments by meta-analysis management

In today's world, improvements that occured in the field of technology required lots of improvements in the field of education, too.It is indicated that with the changes of cirriculum both intramural activities and extrascholastic activities should be used. Hence, someone may come up against the real life problems in the extrascholastic learning atmosphere, thinks about, examines and then come up with the problems. Because the knowledge that have learned in that atmospheres are perceptible information, it makes the process easy and informasitons get permanent. As a consequence of literary searching, lots of studies examining about variety changins about the extrascholastic learning atmosphere efficiency were observed. Hovewer, it was observed that studies examining the generally efficiency of extrascholastic learning atmosphere are limited. That's why, in this study aiming to examine the efficiency of out of school learning atmosphere meta analysis were used. In accordance with the search ,studies searching the efficiency of extrasxholastic learning atmosphere between 2010-2020 were reviewed, examined based on the Higher Education Institue Thesis Centre, data based ,and accordint to the determinated standarts 34 in the academic successtheme, 4 scientific process abilities theme, 5 intended to enviromental attitude, 5 intended to learning science motivation reached general efficiency magnitude with the meta analysis. The efficieny magnitudes of thesis involved in studies were calculates with the V3 program of Comprehensive Meta Analysis (CMA). In terms of academic success, scientific progress skills, attitudes intended to environment, and motivation changeable intenden learning science, it is effective on only extrascholastic learning environments. According to random effective models of extrascholastic learning atmosphere about the general efficiency magnitudes of academic success, it is on intense level with the 1,072; according to constant effective model of general efficiency magnitudes of scientific progress abilities it is on insignificant level with the 0,373; according to random effective model of general efficient attitude intended to environment it is on average with the 0,786; according to random effective model of general efficient of learning science motivation it is on insignificant level with the 0,322 were established. Moreover, according to descriptive analysis of totaly 155 studies incorporated or excluded, years of studies, universities that were done at, fields of study, levels of sample, techniques of extra scholastic learning atmosphere, facility of collection data and techniques of data alaysis and evidence of examined changeables were included. It is stated that there were lots of cognitive changeables according to the dispersion of the years of studies, that done in 2019; in the dispersion according to the university that were examined at, Gazi University; according to the fields of study, the field of numerical (science-math); according to the sample level 5-8 grades at secondary school; accordint to the data alaysis descriptive statics and changeables were examined cognitive changeables mostly occured. This study may be source for the future studies that will be done with commenting under the total results of thesis published about extrascholastic learning atmosphere. At the end of the study, offers were suggested to the searchers about the study that will be done about the topics, to increase the extrascholastic learning atmosphere usage level with pimary school,high school and universities students that cooperated little or never done.
