一节课的好差不在于教师上多少内容,也不在于课题的气氛有多么热闹,关键看学生真正接受了多少知识。效率,在于教师对于教学时间的把握,在于对高效课堂的诉求与钻研态度。在教学过程中,有许多可以供教师利用的工具与方法,如多媒体、实验用品、科学实践,要学会充分利用它们来提高课堂教学的效率。 A good lesson is not how much the teacher content, nor is the atmosphere of the project how lively, the key to see how much the students really accepted the knowledge. Efficiency lies in the teacher’s grasp of teaching time, lies in the demands of highly efficient classroom and research attitude. In the process of teaching, there are many tools and methods that can be used by teachers, such as multimedia, experimental supplies, scientific practice, and learn to make full use of them to improve the efficiency of classroom teaching.
