A meta-analysis published in Educational Psychology Review by Chang and colleagues provides comprehensive evidence on the effectiveness of cross-age tutoring in educational settings. Cross-age tutoring involves pairing an older tutor with a younger tutee at different developmental stages, with the expectation that both participants benefit. This meta-analysis analyzed 31 experimental studies (RCT or quasi experimental design) involving147 effect sizes of academic outcomes. Of these, 28 studies (117 effect sizes) involved tutees, while 14 studies (30 effect sizes) examined the impact on tutors. The tutors ranged from older students in grades 5 through 12 to adult tutors, including university students and community volunteers.
The researchers found that cross-age tutoring generated positive academic outcomes for both tutors and tutees, with an overall effect size of 0.34. Specifically, tutees showed significant academic improvement (ES=0.33), while tutors also demonstrated considerable learning gains (ES=0.39). Importantly, the analysis revealed that student tutors (ES = 0.37) were as effective as adult tutors (ES = 0.25) on tutees, and the intervention proved beneficial for both typically developing students and those with learning difficulties. The positive effects were consistent across both reading and mathematics subjects.
The findings have some implications for educational practice and policy decisions. For instance, the schools can effectively utilize older students as tutors, which offers both economic advantages and feasibility. However, the researchers note several areas requiring further investigation, including cost-effectiveness analysis comparing peer tutoring with adult tutoring, optimal tutoring duration and frequency.
