开放型习题是近几年中考数学的重点也是难点。学生在遇到开放型题目时常感到无从下手,其根本原因在于平时缺乏相应的练习。笔者结合自身多年的教学经验,从设计答案不唯一的开放型习题、设计解法不固定的开放型习题、设计题目带干扰条件的开放型习题,以及设计条件不明确的开放型习题这四方面,谈如何多角度设计初中数学开放型习题。 Open-type exercises in recent years, the focus of mathematics is difficult. Students often feel startled in the face of open-ended questions, the fundamental reason is that the lack of appropriate practice usually. Based on my own teaching experience for many years, from the four aspects of the open-type exercises with unique answers, the open-ended exercises with unsteady solutions, the open-type exercises with designing problems with interference and the open-type exercises with unclear design conditions, How to Design Junior Middle School Mathematics Open - type Exercises from Different Perspectives.
