| 中文摘要 | 傳統電腦輔助教學設計多偏重在練習及展示方面,而且將重點放在由電腦自動教學或處理學習上,「教具及學具」觀點的電腦輔助教學,建議將電腦當作工具,教師根據課程及教材內容(亦不排除非其內的素材)的特質,設計出能幫助教學的教具,或學生操作的學具,供教師及學生在教學時使用,電腦只掌控必要的「工具」,將教學流程、個別差異的考慮、教師的評量……等工作,仍然交給教師。在這種觀點之下,電腦輔助教學之設計簡化,教師只需根據教材或可能的活動內容,充分運用電腦特性來選取或設計合適的教具及學具來輔助教學。本文描述兩位五年級教師,在五年級分數單元利用電腦教學的狀況,我們發現,根據教學需要設計的教具學具電腦情境,在教師以概念引領的方式教學時,確能引發學生思考,建立學生抽象運算規則於具體情境中,電腦的功能也能提供學生思考的方向,但若以展示的方式運用電腦情境,學生的觀察思考,只是在數字關係的表象上打轉,沒有將規則的討論連結到情境上,雖然建立了規則,也能熟練規則,但學生並無機會探索規則形成的原因。 |
| 英文摘要 | Teaching aids are very important facilities for effective teaching. Dynamic mathematics software can be used do design the topic specific teaching and learning aids or environments. Several such teaching aids or environments have been designed on Geometer Sketchpad in previous projects. Each environment is related to a mathematics topic suitable for primary and middle school students. Teachers can design their teaching plan according to these environments. Teachers can select flexible to show or hide content designed on this environment, choose their own teaching pace or sequence according to students' ability, use different teaching method, or ue them as research tools to understand students' understanding. This paper presents the results of teaching experiments of two teachers in the fifth grade on equivalent-fraction and fraction comparison. When teaching with a problem discussion mode, these environments can provide many hints and opportunities for students to develop their equivalent-fraction concept and digging into their origins by subdividing or combining existing segmentation. While using the environments purely for demonstration, these environments can only provide limited help for students to understand the concepts. |
