What is the use of making PPT courseware for online education?
There are many advantages to using PPT in class, mainly including the following:

First, realize student-centered learning and create a harmonious and mutual learning environment.

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.

Second, 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.

Third, 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.

Fourthly, a multi-evaluation mechanism has been established.

In information teaching, the traditional single evaluation is changed, but a multi-evaluation mechanism is adopted to evaluate students' learning attitude, process, interest and degree of mutual assistance and cooperation. This makes the teacher's evaluation of students more comprehensive and objective, which is conducive to promoting the enthusiasm of scholars and improving the ability of independent inquiry.

No matter how much the benefits of information-based teaching are, it is not as good as an action-carrying out information-based teaching. Speed course network provides an efficient and interactive online and offline integrated classroom teaching environment for universities and teachers. Teachers can set up various teaching structures by using the speed class network, such as roll call, online work arrangement, in-class test, classroom questioning, courseware pushing and so on. Carry out information-based teaching anytime and anywhere, realize zero-distance cross-space interaction between teachers and students, help teachers make rational use of classroom time, adjust classroom atmosphere, and stimulate students' learning interaction and enthusiasm, thus further improving teaching efficiency and teaching effect.
