在第二轮复习的阶段,如何在综合复习的同时,有效地和课本结合起来,从而实现课本知识的更新和重建,加深对数学知识内涵与外延的理解,提炼数学思想方法,提高数学学习能力?我利用典型错题,创设问题情景,回扣课本,正确归因,寻找克服错误的有效途径,让学生在复习中经历数学探究的过程,提高复习的效益。 In the second round of review, how to combine the textbook review and the effective review of the textbook, so as to realize the updating and reconstruction of the textbook knowledge, deepen the understanding of the connotation and extension of the mathematical knowledge, refine the mathematical thinking methods, and improve the mathematics learning ability ? I use typical mistakes, create problem scenarios, kickbacks textbooks, correct attribution, to find effective ways to overcome errors, so that students in the review process through the process of mathematical exploration, improve the effectiveness of review.
