科学课堂教学类型通常有:新课、实验课、练习课、复习课。其中单元复习、章复习、期中复习、期末复习、学业考试的复习,大大小小的复习课几乎占了总课时数的1/3。复习课对知识的巩固与提高起了非常大的作用。笔者根据自己多年来失败的教训与微薄的经验,谈谈对复习课的一些肤浅认识。 The types of science classroom teaching are usually: new class, experimental class, practice class, review class. One unit review, chapter review, mid-term review, the final review, review of academic exams, large and small review classes accounted for almost the total class hours 1/3. Review class plays a very big role in the consolidation and improvement of knowledge. According to my own experience of many years of failure and meager experience, talk about the review of some superficial knowledge.
