加强练习是小学数学教学的一个重要组成部分,无论是新授课还是练习、复习课都离不开练习。它是掌握数学知识,形成技能技巧的重要手段,是培养学生能力、发展学生智力的重要途径。数学练习起着形成和发展数学认知结构的作用。而当前小学数学课堂练习的现状不容乐观:(1)盲目多练,目的不明确。(2)习题多、繁、杂、枯燥乏味。(3)题型层次不清楚,学生层次不分明。(4)重书面练习,轻操作实践,如:动手练习、动口练习、社会实践等。
Strengthen the practice is an important part of primary school mathematics teaching, whether it is a new teaching or practice, review classes are inseparable from practice. It is an important means of mastering mathematics knowledge and forming skills and skills. It is an important way to develop students ’abilities and develop students’ intelligence. Mathematical exercises play a role in the formation and development of mathematical cognitive structure. The current situation of primary school mathematics classroom practice is not optimistic: (1) blind more practice, the purpose is not clear. (2) exercises more, complex, miscellaneous, boring. (3) the type of questions is not clear, the level of students is not clear. (4) heavy written practice, light operation practice, such as: hands-on exercises, mouth practice, social practice.
