本研究主要是運用萬用揭示板發展融入Polya解題歷程的國小二年級等化型加減文字題的教材。研究者將設計教材的歷程與兩個循環的實際教學,透過行動研究的方式,蒐集會議紀錄、錄影、省思札記、學生的前後測表現與晤談紀錄等相關資料後,進行資料的整理與分析。本研究獲得主要結果如下: 一、教材位於萬用揭示板教學網,教材編號為3938號。網址位於:http://magicboard.cycu.edu.tw/asp/search/loadobj.asp?pid=3938。 將等化型加減文字題各題型設計於六個頁面,引導學生依Polya解題歷程思考並進行解題。 二、學生學習情形 (一)運用萬用揭示板所設計之教材,融入Polya的解題策略,有助於學生理解等化型加減文字題的題意,並能改變學生的驗算行為。 (二)運用萬用揭示板設計之等化型加減文字題教材進行教學,有助於學習氣氛提升。 三、在教學中學生使用小白板可增加練習,教師也可獲得即時回饋;且讓學生自行操弄萬用揭示板的元件,有助於學生參與學習活動。 四、教師專業成長 (一)研究團隊在教材設計與實際教學回饋,給予研究者很大的助益,讓研究者往後的教學,會藉助教學團隊的協助,讓教學更進一步。 (二)研究時發現使用萬用揭示板的教學,可增進師生間的互動與學生的學習意願,讓研究者在往後的教學會嘗試更多元的教學策略來協助教學。
The aim of this study is to use the Magic Board to develop instructional materials of addition and subtraction word problems for integrating into the Polya problem-solving process of second graders at the elementary school. By means of action research, collecting meeting records, visual recording, reflection journals, the researcher will design the instructional materials and the two-cycle instruction; the pretest and posttest performance and interview records, and other relevant information have been done, we will further go on data collation and analysis. In this study, the main findings show as follows: 1. The instructional materials are located at the teaching network of the Magical Board, whose file No. is 3938. The Website is at: http://magicboard.cycu.edu.tw/asp/search/loadobj.asp?pid=3938. The Addition and Subtraction Equalize Word Problems are designed into six pages, guiding students to think and solve the problems according to Polya problem-solving process. 2. Students' Learning (1) The Magic Board is designed into the use of materials, which integrate Polya problem-solving strategies, contributing to students' understanding of addition and subtraction word problems in meaning, and changing students' behavior of question-checking. (2) The Magic Board is applied and designed for the teaching and learning of addition and subtraction word problems, contributing to lift up the learning desires. 3. In teaching, students use a white board to increase exercise, and teachers can receive immediate feedback; allow students to operate the device of the Magic Board, which can help students to participate in learning activities. 4.Teachers' Professional Growth (1) In the material design and actual teaching feedback, the research team can give researchers a substantial help, allowing researchers to have subsequent teaching assistance from the team for a better teaching result. (2) In the process of study, we found the Magic Board used in teaching can enhance the interaction between teachers and students, and increase students' willingness to learn. Consequently, researchers are encouraged to try more diverse teaching strategies to assist in teaching.
