.best online whiteboard.The traditional teaching method is generally that the teacher asks a question. The students think for a while, and then the individual students answer, mainly the one-way interaction between individual students and teachers, which leads to a kind of thinking inertia of many students. Using the whiteboard, you can first enhance the interaction of the classroom. For example, when introducing the new course of "The Nature of Carbon Dioxide", I took the laboratory method of reviewing carbon dioxide as the entry point, reviewing the main content of the previous lesson and switching naturally. To the topic of the nature of carbon dioxide. When reviewing the laboratory method, students are required to match the device and summarize the circumstances under which the device can be used. In the past, students were asked to combine the teacher's step-by-step drawing on the blackboard or let the students draw sketches on the draft paper, communicate with each other, and then summarize. The use of an electronic whiteboard allows the student to assemble the device by dragging the corresponding analog device with a finger in front of the whiteboard. In the assembly process, every successful step is affirmed in time. If there is a mistake, the teacher or the understaff can correct it in time. In the summary, students can point to the corresponding areas on the whiteboard to explain, so that students can understand the memory. In addition, you can increase the class capacity, select different levels of experimental questions (preferably the middle of the year), and ask several students to come up and operate, leaving traces of learning (the contents of the whiteboard can be automatically saved in the computer) It is convenient for teachers to grasp the student's learning situation in time and correct the teaching content, progress and degree in time. Another example: when studying "Sexual Use of Carbon Dioxide", you can first let the glaciers melt and the land become a desert video, giving students a lot of information that is closely related to life, fully mobilizing students' enthusiasm, and fast-paced, large-capacity Teaching mode. This can save time to encourage students to communicate with each other and discuss their own opinions, forming a good atmosphere of interaction between teachers and students and between students.
