An analysis of effects on affective domain in level differentiated English classes

Abstract

As a follow-up study for meta-analysis on cognitive domain (Park & Yun, 2019), this study aims to investigate the overall effect on affective domain in level differentiated English classes. The procedure of meta-analysis consists of literature search with criteria for inclusion as well as data analysis including data coding and cleaning. After heterogeneity tests, random-effect model, subgroup analyses, and publication bias are conducted using Comprehensive Meta-Analysis software. Moderators used for subgroup analyses were; affective domains, schools, grades, and teaching methods and periods of level differentiated English classes. The results indicate that affective domain in level differentiated English classes had an overall mean effect size (d = 0.33) showing lower effect size than in cognitive domain (d = 0.74). More specific findings of meta-analysis are as follows: First, grouping factors based on affective domain had medium effects in confidence (d = 0.68), interest (d = 0.57) and participation (d = 0.51). Second, according to grade and to students in elementary school through university, the effects were larger with higher grade elementary school students and high school freshmen students. Third, among teaching methods, affective domain showed a large effect in extra supplementary classes. Lastly, the pedagogical implication and suggestions were further discussed.
