本研究的目的是調查學生之間的複雜關係－整體的學習成效、微積分學習成效、使用電腦態度的傾向、MATLAB學習成效和e-portfolio的使用程度。研究對象為國立中央大學的學生。以多重對應分析、集群分析、徑路分析和滯後序列分析為研究方法進行資料分析。
結果發現整體學習成效表現越好的學生，則e-portfolio的使用程度、微積分學習成效、使用電腦態度的傾向和MATLAB學習成效的表現會比較好。進一步探討，同一集群的學生，如果e-portfolio使用程度較高，則微積分學習成效表現會相對較好。
整體而言，使用電腦態度傾向會顯著影響MATLAB學習成效、MATLAB學習成效會顯著影響e-portfolio使用程度、e-portfolio使用程度會顯著影響微積分學習成效、微積分學習成效會顯著影響整體學習成效。

The purpose of this study was to investigate the complex relationship between the achievement in schoolwork, the achievement in calculus, the attitude toward learning mathematics with technology, the achievement in MATLAB and use of e-portfolio. We focus on the students of National Central University, and analysis by multiple correspondence analysis, cluster analysis, path analysis and lag-sequential analysis.
It was found that the students who has good overall achievement in schoolwork the e-portfolio the achievement in calculus, the attitude toward using computer and the achievement in MATLAB will be better than the students who has if. Furthermore, in the same group of students, if they use e-portfolio frequently, then their achievement in calculus will be better.
In conclusion, the attitude of learning mathematics with technology will obviously affect the achievement in MATLAB, the achievement in MATLAB will significantly affect the use of e-portfolio, the use of e-portfolio will significantly affect the achievement in calculus, achievement in calculus will affect the achievement in schoolwork.
