Abstract

Objective: The present study aimed at investigating the efficacy of blended learning, via the meta-analysis of the studies published in some Arab periodicals, from 2008 to 2021 considering some dependent variables.

Methods: The researcher applied the meta-analysis method and used a codebook to collect data. A total of 55 studies met the inclusion criteria of meta-analysis.

Results: The results showed that blended learning has a high impact according to the random-effects model. The average effect size was 1.72, according to Cohen’s indicators, this is a very large value. The effect size indicates the effectiveness of blended learning compared to the traditional method; its efficacy was high in developing achievement, motivation, attitude, and critical thinking. All of this indicated that blended learning has a strong effect on these dependent variables.
