数学是在客观实践中产生的并逐步发展和完善起来的相对独立的知识体系。数学源于实践,又服务于实践。作为数学教师.必须深刻理解教学同实践的紧密关系,掌握它们之间的能动反应。书本知识可以促进实践工作,反过来,丰富的实践活动也有利于书本知识的学习。数学教师不要把自己和学生都死死地捆绑在教科书里,硬啃那些小学生认为枯燥乏味 Mathematics is a relatively independent system of knowledge that is produced in objective practice and gradually developed and refined. Mathematics comes from practice, and serves to practice. As a math teacher, we must deeply understand the close relationship between teaching and practice and master the dynamic reaction between them. Book knowledge can promote practical work, in turn, a wealth of practical activities are also conducive to the study of book knowledge. Math teachers do not put themselves and students are tightly bound in the textbook, hard to chew those pupils think boring
