练习的价值是巩固所学的知识,形成一定的技能,发展学生的思维,激发起他们进一步学习的兴趣。数学的练习常常是封闭的、熟悉的,可以依样画葫芦的。数学练习机械重复的题目、数学练习“熟能生巧”的价值追求,导致有些学生失去了对数学学习的兴趣。练习不能是简单知识的重复练习,不能机械地完成课本上的习题,而应该让学生 The value of practice is to consolidate the knowledge learned, to form a certain skills, develop students’ thinking, stimulate their interest in further learning. Mathematics practice is often closed, familiar, can follow suit. Mathematics exercises Mechanical repetition of the subject, the mathematical practice of “practice makes perfect” value pursuit, resulting in some students have lost interest in mathematics learning. Exercises can not be repetitive exercises of simple knowledge, can not finish the exercises on textbooks mechanically, but should let students
