A meta-analysis of effects of blended learning on performance, attitude, achievement, and engagement in different countries
Abstract Although the new century has been witnessing increasing popularity of blended learning especially during this special pandemic time, few studies have summarized the effectiveness of blended learning in different countries. This meta-analysis summarizes previous studies on blended learning effectiveness in different countries in terms of students’ performance, students’ attitudes towards blended learning, learning achievement, and student engagement in different countries. Through the meta-analysis via Stata/MP 14.0, it is concluded that blended learning could improve performance, attitude, and achievement in most countries. However, in both China and the USA, blended learning could not significantly improve student engagement in academic activities. No significant differences were revealed in student performance in the USA between blended and non-blended learning. Future research could extend the research into blended learning to more countries and areas across the world.
