一直以来,解题都是数学教学的重要组成部分。但是,数学解题“马虎”作为一种普遍存在的现象,却并未引起教师的足够重视,以至于学生频繁失分。因此,高中数学教师应加强对学生解题“马虎”现象的研究,从改变学生数学解题习惯入手,减少学生解题中不必要的错误,进而更好地完成数学知识的学习。笔者结合多年教学经验,总结出以下4种解题“马虎”现象,以此引起师生的关注。1审题不认真例1已知x~2=2py(p>0)为抛物线,经过其焦
All along, problem solving is an important part of mathematics teaching. However, as a universal phenomenon, “mathematics problem solving” “sloppy” has not drawn sufficient attention from teachers so that students frequently lose points. Therefore, high school mathematics teachers should strengthen the study of students’ problem solving “sloppy” phenomenon, starting from changing the habit of students’ mathematics problem solving, reducing unnecessary mistakes in solving students’ problems, and then completing the learning of mathematics knowledge better. The author combines years of teaching experience, summed up the following four kinds of problem solving “sloppy” phenomenon, in order to arouse teachers and students’ attention. 1 moderation is not serious Example 1 is known x ~ 2 = 2py (p> 0) is a parabola, through its focus
