smartboard games for high school.For example, when I was teaching the "Line Segment" lesson, the teacher showed the students the familiar physical objects "pencil, eraser, ruler", etc., and found the line segments when the students found them. At this time, use the electronic whiteboard to drag and hide the function to take the physical image. Remove, leaving only the outline of the graph, abstracting the line segments, rays, and lines, let the students understand the difference between the three. When measuring the length of the line segment, we can drag out several animal pictures from the courseware library and create scenes on the spot so that the students can quickly integrate into the study; the students quickly understand that the rectangles are equal to each other, two points The shortest line segment is the point of knowledge that is difficult for students to remember. Then, using the teaching work provided by the electronic whiteboard, the process of measuring the length of the line segment is visually demonstrated on the screen, and the method for measuring the length of the line segment is further realized by the student. The students are very interested in this! Better reflect the fun of knowledge given by information tools.
