在師資培育的過程中,教學實習課程居於相當關鍵的地位,它提供職前教師們教學見習與模擬演練的機會,本研究主要目的即是建置一個網路同儕互評系統以利於教學實習課程實施,並進一步探討此系統的應用成效。所建置的系統功能主要包括:作業繳交、觀看及互評試教影片、討論區、統計及彙整評量結果等,並在討論及評量時提供影片位置的註記功能,以便學生們的文字評論內容能與試教影片產生具體的連結。同儕互評活動是以分組的方式進行,其程序是評量者在線上瀏覽試教者的教案、講義、及試教影片,並針對各項教學表現給予評分及意見,而試教者也須對評量者的評語作出回應,雙方並可在討論區討論。 本系統實際應用於某國立大學的資訊教學實習課程,其授課內容主要為學生們在校內的教學模擬演練,及中等學校現場的實際試教活動。從系統使用情形分析與活動問卷調查結果顯示,學生們肯定此系統所增進的學習與溝通成效,並認為影片註記的功能可以讓討論與影片的內容相互呼應,是一項不錯的設計。大多數學生們肯定同儕互評活動的效果,他們普遍認為透過網路實施互評活動能夠讓溝通更有效率,並且更能達到觀摩與分享的效果。
The objectives of this study are: (1) to develop a web-based system to support the implementation of peer assessment strategy in a teaching practicum course, and (2) to investigative how such a system helps students’ learning and promotes their reflection skills. The major functions implemented in the system include: uploading/browsing teaching materials, reviewing/assessing peers’ teaching videos, responding/discussing peers’ comments, and summarizing assessment results. In particularly, when students comment on a teaching video, the system allows them to label the teaching video to make their points specific. Thirty-six undergraduate students who enrolled in a teaching practicum course participated in the field-test of the system. Students were required to complete five teaching sessions with video recorded. Five round of peer assessment sessions were conducted by using the system developed. The field-test results indicated that: (1) students appreciated using the system and considered it an effective tool for sharing with and learning from peers, (2) students actively involved in the peer assessment sessions and their reflection skills were improved, and (3) students had better opportunities to evaluate and to reflect on their own teaching.
