Weiping Liu contends that the impacts of learning environments on Chinese only children must be studied from a bioecological systems perspective by considering the direct and joint effects of learning environments and personality within the macro-environments of culture, public policy etc. Samples were chosen randomly from the 1980s and 1990s Chinese only children (N=2105) ranging from junior high, senior high and college students in east, middle and west China. With data analyses such as exploratory factor analysis, hierarchical multiple regression analysis, MANOVA and ANOVA, hypotheses formulated on these research purposes were tested to be true, especially, in terms of desirable learning outcomes. The author also provided practical and theoretical discussions.
