An innovative practical teaching model based on information technology

In traditional teaching model of experimental lesson, the teacher introduces the principles, the devices and the matters needing attention of the experiment to the students before the students begin to do the experiment, the students analyze the result and finish the report after school. If the students have some questions about the result, it's very hard for them to solve the questions through experimental method. In order to free up class time for students to do experiments, improve the efficiency and effect of experimental teaching, a mini-experiment-teaching APP was developed. It can be used by mobile phones with android or OS system. Through it, the students can watch the teaching videos, finish the fundamental questions(just about the background, the principles, the devices, the matters needing attention of the experiments.) and discussed with teachers and classmates. The APP was practiced in experimental lesson of opto-electronic technology, the students must watch the whole teaching video, finish the fundamental questions and get 60 scores before they begin to do the experiment, and must finish analyzing the results of the experiment before they leave the laboratory. The results of practice and survey show that most students prefer the novel teaching model to the traditional teaching model, only one student didn't finish watching teaching video before class. The result of examination shows that the effect of the novel teaching model is better than that of the traditional teaching model, the novel teaching model can also save the teacher's time.
