1　听课、评课欲如何 ?当了 2 0年数学教师 ,2 0多年的数学教研员 ,教研的经历告诉我 ,“听课、评课”是教学研究和交流的重要形式 ,是“指导”教学的最佳途径 ,“方法”在这里显成效 ,“理论”在这里见“公婆” ,经验在这里凝结、升华 ,“学说”在这里孕育、诞生 .因此 ,历来

1 How to listen to classes and classes?

The “best way” is effective here. “Theory” sees here “in-laws” where experience has condensed and sublimated. The “doctrine” was born and born here. Therefore, it has always been
