《义务教育数学课程标准》(2011年版)(以下简称《课标》)指出:“数学课程要面向全体学生,适应学生个性发展的需要……课程内容的呈现应注意层次性和多样性”。基于此,课例《一图一课之二次函数》给出了一个有效的尝试:借助开放题驱动,引领复习课教学。本文从课例的基本事实出发,谈谈对数学开放题及其教学的认识和思考,与同行交流。1亮点分析1.1用开放题设置问题情境
“Compulsory Education Mathematics Curriculum Standard” (2011 Edition) (hereinafter referred to as “curriculum standard”) states: “Math curriculum should be for all students to meet the needs of individual personality development ... ... the course content presentation should pay attention to the level and diversity ”. Based on this, the lesson “a quadratic function of a graph and a graph” gives an effective attempt: to lead the teaching of reflexology with the aid of open questions. Based on the basic facts of the lesson, this article talks about understanding and thinking about the open question of mathematics and its teaching, and communicating with peers. 1 highlights analysis 1.1 with the open questions set the problem situation
