Abstract

雖然坊間存在大量的數學習題為教師提供解題教學素材,但是不少教師在推行解題教學時往往於問題延伸時感到困難。波利亞(G.Polya)是一住出色的解題者,從他的籍作可見他如何就難題作延伸。但他的著作多以大學或中學的數學內容作說明,甚少與小學的數學內容相關。本文將簡述我們如何對初小數學課題作一系列的探究設計及分享我們的一些心得,期望能為前綫的數學教師帶來一些裨益。
Teaching materials are abundant for problem solving in mathematics education. But problem extension and its exploration are no easy tasks. Polya was a famous scholar. He selected numerous university and secondary school mathematical problems and illustrated how he extended a problem. However, we need more examples in primary mathematics, especially for the junior levels. In this paper we shall describe the way we extend a mathematical problem for primary 2 pupils and share our teaching experience. It is hoped that it will make contributions to frontier mathematics teachers. Copyright © 2011 Department of Mathematics and Information Technology, The Hong Kong Institute of Education.
