建立網際網路上物件導向以及個人化的教學環境

Abstract

隨著網際網路的普及，越來越多的老師想在網路上建立教學環境進行教學的活動。因此，如何合適的分配教材給遠距學習的同學就是一個值得研究的方向。在本篇論文當中，我們提出了一個物件化的教材模式：「建立的物件導向的機制之下，將教材合理的切割成一個個的教學物件」。在物件化的教材模式之下，產生的教學教材不再是固定不變的。相反地，所有的教學教材可以動態、個人化的根據學生特質組合而成。 此外，為了能夠有效率地管理切割好的教學物件，在本篇論文中還提出了一個物件導向的課程建構系統。系統中包含了一個個人化的課程建構演算法以及一個課程框架修正演算法。和傳統的教材建構機制比較後，我們的物件導向課程建構系統擁有下列三個特性：個別化、彈性化、以及容易維護性。最後，在實驗的部分，我們根據設計好的演算法實作了以“可延伸標記語言(XML)為資料描述語言“的物件化學習系統，展示了實際應用上的可行性。

The web-based educational systems are becoming more and more popular around the world. Several approaches, which are used to organize the teaching materials appropriately, have been developed in the past ten years [1][2][3][4][6][9]. One of them is just putting all of teaching materials on the web looked just like an electronic book although some friendly user interface or interesting multimedia has been added [1][2][6][9]. Others are adding an evaluation mechanism into system which works at the end of each section of course materials to find out what instructional objectives the students do not learned well [3][4]. According to these evaluation results, the system can offer the remedial teaching materials properly for students to learn again. However, in above two approaches, the students always need to learn all teaching materials at least once no matter how the teaching materials are suitable for them or not when they enter a new section. Therefore, we are interested in developing a tutoring system which can offer different teaching materials for different students in accordance with their aptitude. In order to achieve this goal, both the teaching materials and the students’ profiles should have some attributes and then system can construct different course frameworks for different students accordingly, where the “course framework” in this thesis is defined as the arrangement and representation of teaching materials. However, as shown in Fig. 1.1, the traditional course model usually arranges the teaching materials in sequential and monotonous way. It means that the course framework offered for the students are the same regardless of offering the individualized course framework in accordance with student’s aptitude.
