在数学教学中,把握住教科书中的典型习题,并充分发挥其作用,这对学生学好基础知识,掌握基本技能,培养独立思考和自学能力常常起着不可低估的“龙头”作用;在此基础上,采取“举一反三”的教学方法,对于学生加深基础知识的理解,激发学习数学的兴趣,改变差生视数学为“天书”的畏难情绪,打开优生智慧的大门,又常常起着“润物细无声”的潜移默化作用。
In mathematics teaching, grasp the typical exercises in textbooks and give full play to their role. This will help students learn basic knowledge, master basic skills, and develop independent thinking and self-learning ability. It often plays a “leading” role that cannot be underestimated; At the same time, adopting the teaching method of “taking one thing by the other” has deepened students’ understanding of basic knowledge, stimulated the interest in learning mathematics, changed poor students’ vision of mathematics as “the book of heaven”, opened the door to the wisdom of excellent students, and often played the Silent" subtle effect.
