Meta-analysis of the role of the application of ICT in teaching and learning process on students learning outcomes

brought another technology called information and communication technology (ICT). This technology has a much wider impact capacity, compared to previous technologies, and in the field of education, by being affected by this new capacity, beneficial developments can be made in the pillars of the relevant components. It is a matter of further reflection and understanding in recognizing various aspects, including opportunities or threats arising from the use of this technology. In other words, today the world with the features that have shaped the computer and Internet communications, has emerged to the extent that the networking community has led to the comprehensiveness, complexity and technological networking in various fields. The purpose of the present research was analysis and synthesis analysis presented in the context of the application of ICT in teaching and learning on students’ learning outcome.

The research method is a meta-analysis. The population of the study consists of the written works such as theses and articles available on the websites Irandoc, Magiran, Sid and Noormagz and some papers indexed in journals between years 1387-1394. From among the done works, 36 studies were selected. Data analysis was performed with the help of three software programs, SPSS 22, CMA 2 & EXCEL. For descriptive statistics frequency and percent frequency were used, for inferential statistics, to calculate the effect size G Hedges, fixed effect and random effect model were used. To study the significance of frequency of the research, counting method (chi-square) and in order to combine effects sizes T Vainer possible combination method was used. To study the problem of publication bias in primary studies Funnel chart was used.

It showed that publication bias in the primary study of learning outcome variable existed. To fix this problem, two models of fixed and random effects of Dual and Tweedy fitness test were used. In order to study the homogeneity of the studies, Q and I2 tests were used. The results showed that the primary studies are not homogeneous. Also, the calculated effect size was significant for studies under both models, fixed and random, for the examined variables. Vainer t possible combination results showed that there were significant differences between the combined effects sizes. Finally, the application of ICT in teaching and learning in students' learning outcome is verified

According to the results of the research on the significance of the effect of using ICT in the learning efficiency of learners, it is suggested that practitioners (education planners) to consider the use of teaching aids and the use of new technologies as a priority. It is obvious that the development of ICT expansion infrastructure in the country, especially in educational centers, and providing opportunities for the entry of information technologies into schools and universities without ICT, which creates new social contexts for students to learn, is a key step in this direction. Ultimately, it is certainly the teachers who hold the key to effectively using technology to improve learning, but if teachers do not fully understand how to use ICT effectively to advance student learning, the huge investments made in ICT innovations will be easily wasted. According to the results of the research, it is suggested to encourage teachers to use new technologies in the process of teaching and learning in order to use them more and better, proper training should be held and to raise the level of their scientific knowledge in the above fields. Certainly, in order to succeed in this way, proper investment to equip schools with new technological tools is an important and vital thing that needs to be given more attention by the authorities  .
