从信息反馈的原理来说,学生的作业就是教师教学效果的反馈,故教师必须合理安排作业,以提高课堂教学效率。 1.有计划、有层次、有意识地安排练习题。 一要环绕教学重点,针对学生的特点,除布置巩固新知识的练习,还要布置与新知有联系、学生易遗忘、易混淆的旧知习题。一般地说,可先安排少量试题做,以了解学生理解和掌握新知的情况,然后出一些基本题和变式题以巩固所学的内容;再布置一些对比题和综合题,以培养学生综合运用知识的能力。二要数量适宜、难易适度,让学生练的机会多,花的时间少,提高课堂教学时间的利用率和课堂练习的“密度”。 2.贯彻面向全体因材施教的原则。
From the principle of information feedback, the student's homework is the feedback of the teacher's teaching effect, so the teacher must arrange the homework reasonably in order to improve the efficiency of classroom teaching. 1. There are plans, levels, consciously arranged exercises. First, we must focus on teaching, focusing on the characteristics of students, in addition to arranging the practice of consolidating new knowledge, but also arranged with the new knowledge, students easily forgotten, easy to confuse the old problem. In general, a small number of test questions can be arranged to understand students' understanding and mastery of new knowledge. Some basic and variant questions are then made to consolidate what they have learned. Some comparative questions and comprehensive questions are then arranged to develop a comprehensive Ability to use knowledge. Second, the number of appropriate, easy to moderate, so that students have more opportunities to practice, spend less time and improve the efficiency of classroom teaching and classroom practice of the “density.” 2. To implement the principle of teaching all students according to their aptitude.
