burlington digital whiteboard registration. ????For example, when teaching the "Stereo Graphics" lesson, I prepared a teaching kit such as a toothpaste box, a chalk box, and a basketball, so that each group of students carefully observed the objects. Then, using the electronic whiteboard teaching software, first display a set of abstract graphics on the screen, let the students observe the thoughts and discuss the relationship between the physical objects and the graphics, and then report the different views of their own groups, then the teacher makes a reasonable summary. Through the students' discussion, conjecture, report, and the teacher's summary, the students in the group deeply remembered these three-dimensional graphics. Finally, the teacher uses the electronic whiteboard to decompose the two sides of the physical object on the physical map, and then removes the physical and other graphics, leaving the abstract graphics, thus removing the non-essential representation and extracting the essential definition of the solid graphics. Through dynamic display, activities that seem to be static are activated to give students a correct and clear concept. .
