隨著電腦及網路的普及化,教學活動的地點已經由網際網路取代傳統的教室,形成了所謂的遠距教學。而在教學活動中一直扮演著重要角色的測驗也由傳統的紙筆測驗轉變成線上即時測驗,有許許多多的學者致力於線上即時測驗的發展。 在本文中,將運用「數位題庫系統」、「線上測驗系統」與「即時診斷系統」所構成的遠距測驗環境,作為考生迷思概念診斷之平台。在「數位題庫系統」方面,領域專家可以透過網際網路的環境來達到製作題庫的目的。針對每一道題目,領域專家可以將分析的結果存入題庫,分析的結果包含了試題的概念、試題的答案以及試題的解析。在「線上測驗系統」方面,提供考生參與考試的介面。同樣利用網際網路,考生可以隨時隨地作測驗練習,或是在考試舉行期間,利用網路參加考試。在「即時診斷系統」方面,利用知識地圖產生診斷分析的報表。讓考生可以立即知道自己本身有哪些概念需要再進一步補強,以求達到診斷學習的目的。 本文中,我們藉助了知識地圖的理念,對題庫及測驗的試題作概念階層的分析與知識架構的建立,以期提供考生一個遠距測驗的環境,並且診斷考生的迷失概念,以作為考生的學習參考。在本研究中,將由上述三項在瀏覽器上執行之支援系統,提供具有線上即時迷思概念診斷的遠距測驗系統。
As computers and networks prevailing, the place of teaching activities has been changed from traditional classrooms to the Internet to form distance learning. At the same time, the paper-pencil testing has been replaced by the on-line testing. There are many scholars devoted themselves to the development of the on-line testing. In this paper, we will construct a distance testing environment, which consists of “digital item bank system”, ”on-line testing system”, and “real-time diagnosis system”, to diagnose the examinees’ misconceptions. About digital item bank system, the domain experts can build an item bank through the Internet. Every item can be analyzed by the domain experts. The domain experts can extract the concepts, the answer, and the explanation from an item. With on-line testing system, the examinees can take an exam at any time. The real-time diagnosis system uses Knowledge Map to generate diagnostic reports. The examinees can realize what misconceptions they have through the diagnosis system. In this paper, we use Knowledge Map to find out the concept hierarchy and the knowledge architecture of items. A distance testing environment is provided on Internet for the examinees to take an exam which can give the examinees the misconception diagnostic reports. The above three systems are combined into a complete distance testing environment with the functionality of on-line misconception diagnosis.
