初中生有其自身的特点,他们受年龄的限制,认知水平还比较低,上课也经常出现精力不集中的现象,因此课堂教学效果不理想。教师是影响课堂教学效果的关键因素,本文从教师课前备课、课堂讲解以及课后反思等教学的方方面面进行了阐述,希望对提高初中课堂教学效率有所帮助。 Junior high school students have their own characteristics. They are limited by their ages and their cognition levels are still relatively low. They often have energy concentration problems in their classes. Therefore, classroom teaching is not effective. Teachers are the key factors that affect the effectiveness of classroom teaching. This article elaborates on all aspects of teaching such as pre-lesson preparation, classroom explanation and after-class reflection, hoping to improve classroom teaching efficiency in junior high school.
