The mathematics courses designed by using the electronic whiteboard can be used to maximize the attraction of students' interest in learning, so that students are willing to learn and learn. Feel free to write functions on the whiteboard, draw functions, pull screen functions, focus functions, and timekeeping functions. Each function attracts the students' attention at all times. When the problems that occur in the learning process are different from those prepared by the teacher, the teacher can directly integrate the students' questions into the teaching courseware through the writing function of the whiteboard, so that the students can randomly generate The learning inspiration becomes an integral part of the courseware and can be saved directly in the courseware for reference after class. Can you not be happy when the student??s point of view becomes the content of the courseware?
