In information-based teaching, students' dominant position has been strengthened, which is conducive to giving full play to students' initiative, enthusiasm and creativity in learning. In this teaching mode, students' knowledge is not only transmitted, but also through the network, forums, multimedia and information software. With the help of teachers, students can acquire, analyze and process information independently, thus cultivating their autonomous learning ability.
2. Let modern teaching methods break through difficulties and enlighten students' wisdom.
Some very abstract problems can be intuitively understood and mastered by students through demonstration operation, which overcomes the blank and weakness of previous language expression and can guide students step by step. Intuitive and vivid demonstrations are more likely to stimulate students' interest in solving problems, so that the important and difficult points in the classroom can be solved and mastered one by one.
3. Let lively and interesting question situations stimulate students' thirst for knowledge.
The application of audio-visual display can attract students' attention, stimulate their emotional participation, mobilize their enthusiasm for learning, and lay a good foundation for new curriculum teaching. Practice has proved that the best teaching opportunity is when students have a strong interest in the learning content itself. Only when students form the most ideal learning state can the problems in the situation be solved and the students' thinking ability be cultivated.
