课堂练习题的设计和处理,是提高课堂教学质量的一项重要内容,也是数学教师的一项基本功。课堂练习题的设计相处理,应具有目的性、层次性和灵活性,目的性,就是能体现课堂教学应达到的教学目标,特别是重点学习内容,学生能得到进一步巩固,使思维能力得到进一步发展,层次性,就是能体现教学内容的层次和适应思维层次不同的学生,灵活性,就是依据课堂教学内容的不同层次,及时处理相应的练习题,及时发现和善于处理学生练习时出现的错误,以便为后继层次的教学扫清障碍。这里切忌把所有练习,统统放在课堂的最后阶段处理。
The design and processing of classroom exercises is an important part of improving the quality of classroom teaching and is also a basic skill of mathematics teachers. The design of classroom exercises should be purposeful, hierarchical, flexible, and purposeful, that is, it can reflect the teaching objectives that classroom teaching should achieve, especially the key learning content, students can be further consolidated, and the ability of thinking can be furthered. Development, hierarchy, is the ability to reflect the level of teaching content and adapt to students with different levels of thinking, flexibility is based on the different levels of classroom teaching content, timely processing of the corresponding exercises, timely detection and good at dealing with errors in student practice In order to clear the obstacles for subsequent levels of teaching. All exercises should not be dealt with here at the final stage of the class.
