充分研究习题价值,充分挖掘习题内涵,是一节数学课是否具有内在的教学深度与高度的关键。一般来讲,教师们十分重视备课这个教学环节,但往往忽视或遗漏了对习题的研究,导致在习题使用上随意性大,点评学生练习情况时就题论题,少有延伸拓展、学法点拨。笔者认为,用好用活习题,是提高数学课堂教学效率、增强教学有效性的重要环节。 To fully study the value of exercises and fully exploit the connotation of exercises is the key to whether or not a math class has an inherent depth and depth of teaching. In general, teachers attach great importance to the teaching of this lesson, but often ignored or omitted the study of exercises, resulting in the use of exercises on the arbitrary large, comments on the issue of student practice questions, a small extend, . In my opinion, make good use of live exercises, is to improve the efficiency of teaching mathematics classroom and enhance the effectiveness of teaching an important part.
