本研究主要目的為探討大學生在大學四年來的學業成就與學生自我時間管理兩者之間的關係性。時間管理是否在不同的學科中的影響力有所不同以及其科目是否又對學科總成績有相對的關聯性。
研究過程為依據時間管理之文獻為例，建構一份時間管理的中文版問卷並將問卷透過項目分析去確保問卷實用性，運用因素分析找尋問卷結構之因素，再以相關分析、迴歸分析以及多重對應分析去更進一步探討所有因素與大學學習成就之間的相關性以及英、數學科排名是否可以預測累計排名。
經過施測之後，時間管理問卷具有中高等的信度（Cronbach's α=0.841），而問卷各面向均達到可信的信度（Cronbach's α ≥0.6）。本研究結果顯示在對於上學期英、數兩學科時，短期規劃與學業成就為顯著性的正向相關，而對於下學期英、數兩學科時，短期規劃、時間態度以及長期規劃均對學業成就有顯著性的正向相關，而此三面向也對累積排名均有顯著性的正向相關。上述結果均以多重對應分析之分析圖確認及做更深步的探討。另外英數兩學科可預測累積排名，而下學期學業成就與累積排名的相關性均比上學期學業成就高。再根據以得來的結果與國內外相關之時間管理文獻以及研究比較以及更深一步的探討，最後提出未來研究方向之建議。

The main purpose of this study is to a investigation on the relationship between students' time management skill and their academic achievements over four years of university life. Also, whether time management skill affects differently depending on certain academic subjects and their inter-relationship. In addition, whether these subject have ability to predict the overall ranking was also interested in this study.
The research processes in this study are: first, constructing a questionnaire which is suitable for this study. The questionnaire used in this study was based on a English version of time management questionnaires which was constructed in other related study as a reference, and translated it into Chinese version questionnaire. After the questionnaires were translated, the item analysis was used to ensure its practicability. Moreover, the factor analysis was used to analyze the main factor of Time Management questionnaire. Finally, after applying data using correlation analysis, linear regression analysis and multiple correspondence analysis, the conclusion of questions of interest was drawn.
After completing and analyzing survey, the reliability analysis resulted with Cronbach's α=0.841 which meant medium to high level of reliability, and also the result of all of its subscales' (factors') reliability reached certain level of reliability with Cronbach's α≥0.6. The outcome of this study demonstrated that the grades of both of subjects (English and Math) in the first semester had positive and significant relationship with Short-Term Planning, and for the second semester, the grades of both of subjects are positively and significantly related to all three factors. Moreover, these three factors were positively and significantly related to Overall Ranking. By using multiple correspondence analysis, the result can be confirmed and led to further discussion on the correlation. Furthermore, both of the subjects' Academic Achievement had ability to predict the Overall Ranking. Then, the study compared its outcome with other similar researches and discussed their difference. Fianlly, the proposal for the futher investigation can be proposed.
