练习课是新授课的补充与延续,其主旨在于让学生通过独立)练习巩固新知、掌握技能,同时起到发展学生数学思维和激发学习兴趣的目的。练习课应该要有一定的练习量,但练习量显然不是衡量练习课质量的唯一标准,更关键的是要看练习的思维含金量,看恰当题量的基础上,能否调动起学生进一步学习的积极性,使练习课的40分钟成为学生后续学习并搭建数学研究的平台,这应当是数学练习课追寻的终极目标。结合一线教师教学体悟,笔者 The practice class is a complement and continuation of the new class. Its purpose is to enable students to practice new knowledge and acquire skills through independent practice. At the same time, they aim to develop students’ mathematical thinking and stimulate their interest in learning. Practice class should have a certain amount of practice, but the amount of exercise is clearly not the only measure of the quality of practice class, more critical is to look at the gold content of thinking practice, to see the appropriate questions based on the ability to mobilize the students to further study Enthusiasm, so that 40 minutes of practice class to become students follow-up study and build a platform for mathematical research, which should be the ultimate goal of pursuing mathematics practice class. Combination of front-line teacher teaching comprehension, the author
