摘要

By presenting an illustrative meta-analysis, we discussed some issues to be noted when meta-analyzing results of observational studies in which dependent variables are dichotomous in nature. The purpose of the exemplary meta-analysis is to explore the possible effects of children's retention .experiences on their dropout behavior later on. We retrieved 34 artic1es which consist of 21 independent data sources and coded 66 effect-size indices, out of which 10 were used for analyzing the effects of retention and 14 Were used for analyzing the effects of over-aging.The findings are that, while students with retention experiences were three times more likely to drop out of high school than those without (OR=3.02, z= 8.36, p＜ .001), the effects of over-aging reached only marginal significance (OR=1.33, z=1.69, p＞ .09). The results suggest strongly that being held back by the school could have significant negative impacts on students and the practice of retention did not help students to be more mature and ready for school learning. After some discussion on the implications and limitations of this meta-analysis, we use a check list to examine the merit of this meta-analysis.
