With PPT and multimedia, is the traditional blackboard writing still necessary?

Traditional blackboard writing is still necessary, and multimedia and PPT are just a form of expression. Traditional blackboard writing and multimedia have their own advantages and disadvantages. Multimedia has appeared in recent years and is widely used in teaching. Usually the teacher will put the teaching content on PPT and then show it on the multimedia screen. The advantages of multimedia are good performance and simple operation. The teacher only needs to click the mouse, not write on the blackboard. Then there are rich teaching resources on multimedia, which is very important. For example, in junior high school geography, teachers can play some teaching videos through multimedia, such as aerial photography of China, and show the contents of geography books with actual pictures, which can strengthen students' interest in learning and play a better teaching effect.

The application of multimedia is a step to implement intelligent teaching, and there are many multimedia applications at this stage. From primary school to university, multimedia screens are being used, and teachers' endless creativity is displayed on the multimedia screens, which provides sufficient content for classroom teaching and makes many students like multimedia teaching forms. For teachers, multimedia teaching will also be more convenient, which means that a PPT can be used for a long time. It takes some time to do it well in the early stage, and then you can use it all the time instead of writing on the blackboard every class.

In fact, the traditional blackboard writing still has its significance. Although multimedia teaching has many advantages, the most obvious problem is that many students don't take notes. Moreover, after the PPT page is turned, the previous teaching content can't be recorded, and the blackboard book exists for a long time, so students are more willing to take notes. This is more reflected in university teaching. Many students took PPT with their mobile phones, but never watched it again. Therefore, the traditional blackboard writing still has its significance and cannot disappear.
