在教学一线的同仁应该有这样的感觉:一堂课前准备十分充分的公开课,常因教学环境、课堂节奏、临场发挥等因素的影响,上得不尽人意,留下遗憾.相反地,在日常教学中,课前准备并不充分,却能在课堂上将问题铺展开来,引向深入,举一反三,学生收获不少,教师余味无穷地离开了教室.下面这 At the teaching level, my colleagues should feel that having a fully prepared open class before class often results in disappointment and regret because of the influence of teaching environment, classroom rhythm and on-the-spot play, etc. On the contrary, In daily teaching, pre-class preparation is not enough, but it can spread the problem in the classroom, leading to in-depth analysis, giving top priority to the many, the students gain a lot, the teacher aftertaste endless left the classroom.
