中等职业教育教学新教材明确指出:“以服务为宗旨,以就业为导向”。遵循培养高素质劳动者的目标的基础上,突出基础性,在保证科学基础上,不刻意追求学科体系的完整性,降低教学难度,减轻学生负担。新教材打乱这种完整性,数学是个体系啊,能这样教和学吗?作者带着疑问开始新教材的实践。 The new teaching materials of secondary vocational education made it clear that: “to serve for the purpose of employment-oriented ”. On the basis of following the goal of cultivating high-quality laborers, we should give prominence to the foundations and do not deliberately pursue the integrity of the disciplinary system on the basis of guaranteeing science, so as to reduce the teaching difficulty and reduce the burden on students. New materials disrupt this integrity, mathematics is a system ah, can teach and learn this way? The author starts with the practice of new textbooks.
