The purposes of this study was to test the interaction effects among action vs. state orientation, goal level, and task complexity on junior high school students' action control strategies and task performance (including writing quantify and quality). For this purpose, a2×2×2(action vs. state orientation×goal level×task complexity) experimental design was adopted. 320 Subjects (action orientation 160, state orientation 160) were selected from 4 junior high schools and randomly assigned to one of the eight experimental conditions. Three-way ANOVA was employed to analyze the data. The results showed that There were significant three-way interaction effects among action vs. state orientation, goal level, and task complexity on subjects' action control strategies and writing quantify and two-way significant interaction effects between goal level and task complexity on subjects' writing quality.
