很多高中生在学习数学的过程中,遇到课本上的原题和同类型的题,可以较为轻松地解答出来,但遇到稍加变形的题目,就很难找到正确的解题思路。造成这一问题的根本原因在于学生的思维不够开阔。因此,教师在教学的过程中,要注意引导学生发散思维,从不同的角度分析理解问题,拓展思维的空间,灵活地将题目联系起来。一、通过开放性问题拓展思维空间开放型问题的特点是题目条件开放,结论答案不固定,答题方式多种。学生在做这类题的过程中,必须 Many high school students in the process of learning mathematics, textbooks encountered on the original title and the same type of questions, can be more easily answered, but encountered a little distortion of the subject, it is difficult to find the correct problem-solving ideas. The root cause of this problem is that students are not sufficiently open-minded. Therefore, in the process of teaching, teachers should pay attention to guiding students to diverge their thinking, analyze and understand the problem from different perspectives, expand the space of thinking, and flexibly link the topics. First, to expand the thinking space through open issues Open-ended questions are characterized by the openness of the subject conditions, the conclusions of the answer is not fixed answer a variety of ways. Students in the process of doing this kind of question, must
