■主持人语／张文杰说课，是老师在特定场合，针对特定的教学内容，阐述自己的教学设计及理性思考，并由听讲教师评议，所有教师相互交流、提高的教研活动。虽与备课一样都是为了上好课所做的课前准备，但不同于备课的是，说课不仅要说准备好的教学方案怎么教，而且要说备课中 ■ Moderator’s Language / Zhang Wenjie’s class is a teacher’s instruction on specific teaching content for specific teaching content, expounding his own teaching design and rational thinking, and listening to the teacher’s comments. All teachers exchange and improve teaching and research activities. Although the preparation of class is the same as preparation for classes, it is different from lesson preparation. The lesson is not only about how to prepare a prepared teaching program, but also to say that preparation is in progress.
