中职学校的教学目标是以能力为本位、就业为导向,培养出一批具有一定专业技术水平和技能的实用型人才。然而,因为中职学校的学生本身文化基础比较差,导致他们学习起来有很大的困难。尤其是数学学科的学习,学生没有学习兴趣,所以课堂效率极其低下。因此,提高课堂效率、构建高效课堂就成为中职学校数学教育的重中之重。 Secondary vocational schools teaching objectives are based on ability, employment-oriented, train a group of a certain number of professional and technical skills and practical talents. However, because secondary vocational school students themselves have a poor cultural foundation, it is very difficult for them to learn. Especially in mathematics, students are not interested in learning, so the efficiency of the classroom is extremely low. Therefore, to improve the efficiency of the classroom, to build efficient classroom became the top priority of math education in secondary vocational schools.
