文章以新课程理念为背景,首先反思了中学数学教学中的“无效探究”问题,其次将“课堂提问”与“多媒体辅助教学”中存在的无效行为进行总结,并提出改进措施。最后提出抛弃传统讲解、注入的教学方法,将学生当作课堂主体,从而全面提升数学学科成绩。 Based on the idea of ​​new curriculum, the article first reflects on the problem of “invalid inquiry” in mathematics teaching in secondary schools, and then summarizes the invalid behaviors in “classroom questioning” and “multimedia assisted instruction” and puts forward improvement measures. At last, it puts forward to abandon the teaching methods of traditional explanation and infusing, and regard the students as the main body of the class, so as to improve the mathematics achievement in an all-round way.
