應用數學一般化教導學生3與11數字倍數的辨認

Utilizes mathematical generalization to teach students judge the concept of multiple of number 3 and 11

本研究目的在於運用數學一般化的概念與步驟，指導學生理解速算法的意義，以能正確的辨識3 和11 的倍數問題。經由教學後，學生除理解速算法的意義外，更能將速算法轉換成更加有效的策略，進行數字倍數的辨認，對於提升學生思考、促進推理，具有實質的效益。

The aim of this study is to utilize concept and process of mathematical generalization to instruct students understanding the meaning of the convenient method that to judge the multiple problem of number 3 and 11 correctly. After teaching experiment, students can understanding the meaning of the convenient method, and transform it into more effective strategies to problem solving, the strategies can promote students thinking and reasoning.
