「中草藥用藥」之主題地圖式數位學習教材建構與應用 The Construction and Application of Chinese Herb Medication Digital Learning Material Using Multi-level Topic Map

Abstract

本研究之主要目的在於運用資訊科技來建構數位學習教材，規劃並建議學習之應用方式。我們在「神農e經：中草藥用藥典範數位學習內容開發及實地實驗研究」中開發了多層次的主題地圖數位教材模組，能夠自動擷取各種不同來源的中草藥用藥學習素材，由課程引擎使用自我組織映射（SOM）演算法，自動編製成多層次的主題地圖，有效的將原始資料組織成具有專業意義的學習材料。主題地圖之教材應用具有幾項特點：呈現豐富多元且專業的資料與其知識架構、提供客制化與互動化的學習機制以支援系統化與建構式學習、經由自動演算系統提供簡單易懂的操作機制。因此，學習者得以藉此獲得最即時與正確的中草藥用藥安全知識。This research aims to use information technology to construct digital learning material, and discusses its design and application possibilities. This paper presents the process and result of our research related to the project “Shannon Sutra: Digital Learning Content and Experimental Research on Chinese Herb Medication Safety” granted by National Science Foundation. In this research, we use multi-level topic map digital learning material model to render tremendous original assets, and then embed text-mining techniques in course engine to produce topical learning materials. The autonomous method can process raw data and original document to generate meaningful search results, and thus develop to be well-structured learning material. Self-Organizing Map system helps to demonstrate rich and professional information and knowledge structure; it provides customized and interactive learning dynamic to support both progressive and constructive learning styles; it has autonomous system to afford easy and convenient operation for information search. With topic map system, learners can interact with the dynamic topic map and receive instantaneous and accurate feedback of most wanted result.
