问题提出:从课程设计到课堂实践

Problem Posing:From Curriculum Design to Classroom Practice

问题提出是数学和其他学科中必不可少的实践活动,它是通过给定的情境来生成和表述问题的过程。虽然国内外的课程标准一致认可问题提出的重要性,但是在教科书和课堂教学中,问题提出既不充分也不连贯。针对这些现状提出的三点建议,为教师和学生从事问题提出活动提供了一个较低的门槛,只需要对普通的数学活动和课程材料进行较小的改动。

Problem posing,the process of formulating and expressing problems based on a given situation,is an essential practice in mathematics and other disciplines.Although this is acknowledged in domestic and foreign curriculum stan dards,problem posing is neither substantively nor consistently included in school mathem atics.This paper makes comments on the state of problem posing in school mathem atics and provides three recom m endations to improve its integration into textbooks and classroom teaching.These recommendations present a low barrier to entry for teachers and students and require only minor changes to common m athem atics classroom activities and curriculum materials.
