iqboard ubuntu.For example, in the teaching of junior high school physics "Electric Experiment", in order to let students better grasp the connection of the circuit, you can directly use the resource library of the whiteboard, which provides almost all the physical maps in the physical experiment, which can be used by the electronic pen. A selected set of experimental equipment (current meter, voltmeter, sliding rheostat, power supply, switch, etc.) is dragged, scaled, and adjusted. Use the line drawing and erasing functions to allow multiple groups of students to participate, and connect the circuit diagrams on the whiteboard as required. The results of group experiments are saved in the corresponding folders. These operations enable students to directly experience and experience the fun of physical experiments, far more than the teacher repeatedly on the blackboard, or simply use PPT , FLASH courseware to demonstrate the effect.
