線上學習成效分析系統發展與研究

Abstract

傳統教學上評量學生的學習成效，一般皆以學生對一個課程內容了解與否為依據，惟介於兩個極端分界之中，仍實際存在著許多模糊空間，所以在評量學生的學習成效時，對於學生評量測驗的結果，無法知道學生對課程概念的認知程度。 本文將以大學修習數控工具機之學生作為研究對象，建構線上學習成效分析系統，應用模糊德菲法整合老師問卷之資料，得到測驗題與概念權重矩陣，透過綜合評量進行學生對課程概念認知診斷，提供語意化呈現方式，並針對獨立樣本進行T考驗，了解兩組間平均數差異情形。

The evaluation of learning effectiveness in traditional teaching is based on whether students understand or not. But between the two limits, there exists vagueness. Therefore, traditional evaluation can not judge the effectiveness of understanding in learning. This study constructs on-line system to evaluate the learning effectiveness and give an example of students, which study numerical control machining in college. Using the fuzzy Delphi method to integrate and analyze the collected data from teachers, the test sheet and concept matrices are obtained. The developed system provides a diagnosis on the understanding in the course and a semantic representation. The variance between two groups can be understood by using T-test on independent samples.
