课堂教学是教学过程的主要环节，如何上好每一节课是教学工作成败的关键。本着“功在课下，果在课上”的原则，充分有效地利用４０分钟，并辅之以恰当可行的方法，才能使教学质量不断提高，本文就课堂教学设计的策略谈一点体会。一、设计好复习与导新数学知识有着严密的逻辑结 Classroom teaching is the main part of the teaching process, how to improve each class is the key to the success or failure of teaching. In the “work under the class, the fruit in the class” principle, make full and effective use of 40 minutes, supplemented by appropriate and feasible method, in order to improve the quality of teaching, this article on the teaching of classroom design talk about some experience. First, the design is good review and guide the new mathematical knowledge has a close logical knot
