This study set out to investigate whether inclusive education(inclusive care) experiences would have
significant effects on the promotion of teachers' perceptions, one of the important elements to determine
the quality of education, by systematically reviewing the previous studies with different conclusions,
conducting total analysis of them, and drawing a big conclusion. It was part of efforts to reach total
conclusions out of an academic controversy based on the grounds at the current point and make a
contribution to practical implications to increase the quality of inclusive education. For analysis, the
investigator identified through academic information search 20 previous studies that analyzed relations
between experiences with inclusive education and changing perceptions among teachers from 2000 to 2013.
Following the meta analysis procedure, the study also calculated the mean effect size based on the
standardized mean difference and effect size calculation method. The analysis results based on the
confirmation of data heterogeneity and random effect model found that the mean effect size was .252(the
intermediate level) and that the percentage value was 60% under statistical significance. Based on those
findings, the study discussed practical implications for confirming the importance of inclusive education
experiences themselves to promote the teachers' perceptions, granting legitimacy to the compulsory
application of inclusive education, and making it mandatory to provide education on the promotion of
experiential perceptions(e.g., internship and in-service training).
