在数学教学中开放性习题因其开放性、灵活性、多变性给学生的思维创设了一个更广阔的空间,有助于激发学生的创新意识,养成创新习惯,发展思维的创造性,提高学生分析问题、解决问题的能力。根据笔者多年的教学经验,设计开放性习题可以从以下几个方面考虑。一、条件开放的策略传统的练习设计,条件是所求问题的充要条件,容易给学生造成思维的定式。当遇到条件不足或条件有余时,感到束手无策或疑惑不解。设计条件开放的开放题,可以提高学生分析问题、解决问 Open math in mathematics teaching because of its openness, flexibility and variability to the students thinking to create a broader space, help to stimulate students’ sense of innovation, develop innovative habits, develop the creative thinking, improve students Analysis of the problem, the ability to solve problems. According to my years of teaching experience, the design of open exercises can be considered from the following aspects.
