本研究之主要目的為（一）了解教師期望是否會形塑學生的學業自我效能，進而影響學生的逃避行為，意即學業自我效能是否會中介教師期望對於逃避行為的效果。（二）上述中介效果若成立，那麼個人成就目標是否會調節此中介效果。為完成研究目的一與二，本研究收集台南地區9名教師以及其所教授之447名七、八年級國中生的資料，以數學科為特定領域。測量工具為自編教師期望量表、學業自我效能量表、個人成就目標量表以及逃避行為量表。所測得之資料以結構方程模式（SEM）進行分析。
本研究的發現如下：
一、學生的數學學業自我效能的確為教師期望對於逃避新奇效果的中介變項，且為完全中介。進一步分析顯示：教師期望能夠正向預測學生的數學學業自我效能、負向預測學生的逃避新奇，學生的數學學業自我效能則會負向預測逃避新奇，並且當教師期望與數學學業自我效能同時預測逃避新奇時，教師期望預測逃避新奇的效果會下降為不顯著。
二、趨向表現目標以及逃避精熟目標可調節「教師期望—學生學業自我效能—逃避新奇」之效果：當逃避精熟的水準增加時，教師期望透過學生學業自我效能影響逃避新奇的負向間接效果會隨之增加；當趨向表現的水準增加時，教師期望透過學生學業自我效能影響逃避新奇的負向間接也會隨之增加。
本研究根據研究結果進行討論，並提出教學輔導與未來之建議

The main purpose of this study were (a) to examine whether students' academic self-efficacy mediates the effect of teacher expectations on avoidance behavior. (b) If the above mediating effect is established, then whether personal achievement goals will moderate this mediating effect.
To accomplish research objectives 1 and 2, this study collected data from 9 teachers in Tainan and 447 middle school students in grades 7 and 8, and using Structural Equation Modeling (SEM) for analysis.
The result of this study were summarized as following: (a) Students' mathematics academic self-efficacy mediating the influence that teachers' expectations for avoid novelty. Further analysis shows that teachers' expectations can positively predict students' mathematics self-efficacy and negatively predict students' avoid novelty. and self-handicapping; students' mathematics academic self-efficacy negatively predicted avoid novelty.(b) The conditional indirect effect of performance approach and mastery avoidance on "teacher expectations - students' academic self-efficacy – avoid novelty" is established. Further analysis shows that: when the level of mastery avoidance increases, the negative indirect effect that teacher expectation influences avoid novelty through students' academic self-efficacy increases; on the other hand, when the level of performance approach increases, the negative indirect effect that teacher expectation influence avoid novelty through students' academic self-efficacy also increase.
