一节数学新课教案,主要是由例题教学和课堂练习组成。它们是一个有机的整体,课堂练习是例题教学的延续和提高。学生的知识必须经过练习,才能转变为技能。因此,课堂练习必须发挥它在数学教学中的作用。课堂练习有巩固新知识的单项练习和发展智力的综合练习。其中,首要的是要设计好单项练习。进行单项练习,应使学生的注意力集中到最主要的一点去,这样花时少,练习量却可成倍提高。这种课内单项练习,反馈快,便于及时纠正错误,可确保教学要求落实到每个学生,使之达到当堂巩固。既可减轻学生课外负担,又可提高教学质量。
A mathematics lesson plans, mainly by the sample teaching and classroom exercises. They are an organic whole, and the practice in the classroom is a continuation and improvement of the example teaching. Students' knowledge must be practiced before they can be transformed into skills. Therefore, classroom practice must play its role in math teaching. Class exercises include consolidating new knowledge of individual exercises and development of intelligence exercises. Among them, the first is to design a good practice. Individual exercises should focus the students' attention on the most important point so that they can spend less and exercise more effectively. This single class practice, fast feedback, easy to correct mistakes in a timely manner, to ensure that teaching requirements implemented to each student, so as to achieve the goal of consolidation. Can reduce the burden of extra-curricular students, but also improve the quality of teaching.
