教学实践告诉我们:高中学生在生理发展和心理特征上的差异是客观存在的;对数学的兴趣和爱好、对数学知识的接受能力的差异也是客观存在的。尤其是普通高中,学生素质参差不齐,又存在能力差异,导致不同学生对知识的领悟与掌握能力的差距很大,这势必对高中阶段的数学教学带来负面影响,因此在普通高中数学教学中试行“分层教学”就显得格外重要。那么,如何在普通高中数学教学中应用“分层教学”呢?我从以下几方面进行说明。一、创造良好的环境 The teaching practice tells us that the differences in the physiological development and psychological characteristics of senior high school students are objective. There is also an objective difference in the interest and hobby of mathematics and their acceptance of mathematical knowledge. Especially in ordinary high schools, the quality of students varies and there are differences in ability, resulting in a great gap between the different students’ knowledge and grasp of knowledge, which is bound to have a negative impact on high school mathematics teaching, so in the ordinary high school mathematics teaching In the pilot “hierarchical teaching ” is particularly important. So, how to apply “stratified teaching ” in ordinary high school mathematics teaching? I explain from the following aspects. First, create a good environment
