本研究以社會認知生涯理論作爲基礎,旨在透過TIMSS 2003台灣資料庫的二級資料分析,企圖建構並驗證一套學生選擇職業意圖的因素結構模型,以探究男女學生在選擇科學職業意圖上的差異,並且比較其中的性別差異涵義。本研究發現,影響未來是否選擇以科學作爲職業意圖的因素,呈現性別差異的存在;其中,女學生以科學學習興趣,男學生則要覺知科學的益處和效用,兩性唯一的共同因素是科學有用性,亦即覺知到科學對生活的助益,均是影響學生未來選擇以科學作爲職業進路的關鍵因素之一。另外,學生的科學成就必須透過科學自我效能,才能對科學學習興趣產生影響。最後,本研究亦根據研究結果,提出在教育實務應用與未來繼續研究上的建議。
The purpose of this study is to do the secondary analysis of TIMSS 2003 dataset of Taiwan for investigating the sex differences in science career choice process. A latent variable model based on the social cognitive career theory was proposed, tested, and verified with another split-sample from the same population. The results showed that the science career-choice intentions model would be different by gender. Among them, learning interests would be a main impact factor on females' science career-choice process, and the self-efficacy in science on males' model. The common impact factor on gender for science career-choice process was science outcome expectations. The science achievement had an indirect effect on science learning interests, with the science self-efficacy as a mediator. Finally, some conclusions and suggestions for practical applications and future researches were suggested and proposed.
