.interactive smart boards.An interactive whiteboard is an innovative application, and teaching is systems engineering. If you rely solely on the application of one or several new technologies and new tools, you can completely change the structure of classroom teaching, or the level of change in classroom teaching and student learning. This view is at least unrealistic at present. The change of teaching methods and the change of learning methods are firstly the change of curriculum concept, teaching concept, teaching design concept and student learning concept, which is the change of classroom teaching method and student learning style. In the context of education informatization, it is possible to promote ??mode change?? through ??technical change?? and ??tool change??. If there is no advanced teaching concept, even if a new technology such as an interactive whiteboard is used in the classroom, the teaching is organized with old teaching thoughts, and such a "new bottle of old wine" cannot take advantage of it. Our teachers still have to ask themselves: I used an interactive whiteboard for this class. What did the students get? Does it promote "teaching" or promote "learning" or vice versa?
