Abstract

本研究之目的在發展一情境感知系統輔助國小自然科戶外教學,並評估其使用效益。本研究發展之情境感知系統使用PDA做為行動載具,利用GPS做為定位方式,發展之功能包括地圖導覽、路徑記錄、地圖編輯、戶外教學學習資源及學習單等。系統評估的參與者為台北市某國小的一位自然科教師與35位五年級學生;教學活動係由教師帶領學生於校園及關渡兩處進行戶外教學活動,教學時間共計10小時;評估方式則是透過問卷、課堂觀察、教學活動錄影及教師訪談等瞭解教師及學生對系統的使用情形。研究結果發現,本研究所發展的系統有助於戶外教學的實施,並能提升學生的學習興趣,且有助於教師設計更豐富的戶外教學學習活動。最後,本研究建議:教師需更充分的教學準備時間,並可考慮使用其它的定位技術,以求更精確的地圖導覽。
The purposes of this study are to develop a context-aware system to facilitate outdoor-learning activities of elementary science classes and to evaluate the effectiveness of the system. The context-aware system was developed on a PDA-based environment which equipped with a GPS component. The system provided students with the following features: navigating on field trip locations, recording places which students visited, adding interested locations on the map, reading learning resources, and writing worksheet. We evaluated the effectiveness of the system by conducting two outdoor learning activities: one in the campus and the other in a nature park. The participants were a science teacher and a class of 35 5th grade students. The findings of this study are: Our system is helpful in facilitating outdoor learning activities, and the students showed positive attitudes towards using the system, and it can enrich the design of outdoor learning activities. Finally we offer some suggestions the teacher needs more time of preparing in teaching and might use other location techniques for better precise navigating on field trip locations.
