摘要
本研究旨在探討遠距視訊專業成長計畫促進國小自然與生活領域教師教學角色與課堂學習活動的改變及影響改變之因素。研究對象為參與遠距視訊教師專業成長計畫之夥伴教師，研究期程為一年，主要研究方法為質性研究法，以「教師教學角色表現觀察與評分表」做為觀察與蒐集教師教學表現及課堂學習活動的主要工具，輔以自然領域教師科學教學態度量表、學生學習科學態度量表、訪談、會議資料做為佐證資料，以獲得研究結論，本研究結論如下：
一、夥伴教師在參與遠距視訊專業成長計畫之後，教師教學角色從講述型到概念型皆有，教學角色層級漸有提升。
二、學生課堂學習活動從以教師為中心的漸轉變為以學生為中心導向的課堂學習活動，學生學習的方式變多元，以討論、實驗、操作、主題報告等學習活動來取代聽講。
三、影響教師教學角色改變因素為：遠距專業成長計畫營造支持教師學習的環境、回饋幫助教師改變、回到現場後教師教學獲致支持。
四、遠距視訊專業成長計劃促進教師教學角色與課堂學習活動的變化，肯定文獻中有關同步回饋的功能。
最終，研究者依據研究結果針對後續教師專業發展方案及未來研究提出建議以供參考。

關鍵詞：遠距視訊系統、自然領域教師專業發展、教學角色、課堂學
習活動。

Abstract:
The present research aims to explore the transformation of the teachers’ role and the study activities in classes under the promotion of the remote video system in the natural and daily domain of the primary schools, and to study the factors affecting the transformation. The research objects are the partner teachers participated in the professional scheme concerning the remote video system and the growth of the teachers. The qualitative research is mainly used, and the author uses the observation and score tables about the performance of the teachers as the major instrument, observing and collecting the performance of the teachers and the study activities in classes. The author also combines the scientific scale of the teachers’attitude in the natural domain, the scientific scale of the students’learning attitude, interviews and the conference materials to achieve the research conclusions. The research results are as follows:
1. The remote video system promotes the change of the teachers’role and the activities in classes, and affirms the feedback function about the literature which promotes the development of teachers’professional abilities.
2. The discussions in classes promote the change of the role of teachers in partner schools, and the classes become students-centered.
3. The study activities in classes has also changed, but the students haven’t developed their self-study ability.
Finally, according to the research results, the author offers suggestions concerning the professional developing scheme of the subsequent teachers and the future research.
Key words: the remote video system, professional development in the nature domain, teaching role of teachers, classroom activities.
