新课改对教师提出了新的挑战,对教师备课提出了更高要求。备课是教学的重要行为之一,是教师上好课的关键。自“有效教学”的理念进入我们的教学课堂后,“教学是否有效”不再以教师有没有教完教学内容,教得认真不认真为指标,而是更注重学生学到了什么,学得好不好。如何备课,课备得好不好,应以促进教师进行有效教学,让学生得到有效发展为根本。 The new curriculum reform poses new challenges for teachers and puts forward higher requirements for teacher preparation. Preparation lesson is one of the important behaviors in teaching, which is the key to teachers’ good lesson. Since the “effective teaching” concept into our teaching class, “teaching is valid ” is no longer the teacher did not finish teaching content, teach seriously not serious as an indicator, but pay more attention to what students learned Learn well or not. How to prepare lessons and how to prepare lessons well should be based on promoting teachers’ effective teaching and effective development of students.
