? PPT is a kind of media, which is used with computers. Teachers use PPT in class, which means that we can use the computer to find knowledge at any time.
The network world is very developed, and all kinds of information can flash in front of you in an instant. Therefore, the use of PPT can greatly expand our horizons and help us understand and remember the contents of textbooks through the combination of numbers and shapes.
The traditional way of attending classes is just to talk about knowledge by the book, but if you want to acquire extracurricular knowledge, you must teach it orally and actively expand it.
But the teacher's life experience is limited after all, and his communication ability is uneven, so students can't understand it well.
If we use PPT, we can search the corresponding videos and pictures on the Internet at any time. This method can make students know something more intuitively. Both students and teachers will like this kind of class.
However, the use of PPT is limited to liberal arts, which is why when we are in math class, we rarely see math teachers use PPT to teach students.
Take the subject of mathematics as an example, because every class has to learn a lot of formulas and reasoning, and these formulas and reasoning must be written on the blackboard by the teacher himself, and the students can follow the calculation, so as to bring a deep impression to the students.
For subjects that don't need to expand a lot of extracurricular knowledge, PPT is not so widely used.
Therefore, the best way to attend classes is to combine traditional classes with PPT. You can't just use PPT and abandon the traditional classroom, otherwise you will feel a little desperate.
