The teacher used PPT instead of blackboard writing. What are the advantages and disadvantages?

In classroom teaching, whether you use blackboard writing or PPT, it is for the needs of classroom teaching and is an auxiliary means for teachers to attend classes. According to my listening experience, if a class is all blackboard writing or PPT, it will be a bit boring, monotonous and boring, which will affect students' listening experience. I think we should use PPT or blackboard writing? It should be decided according to the actual needs of classroom teaching content. The biggest advantage of PPT is that it can show students knowledge intuitively and vividly. In addition, it can increase the ability of teachers.

As one sixth of the world's population, in order to adapt to the future lifestyle and working style, we must analyze whether PPT education or blackboard education is possible. What we should see is the benefits of PPT education. When doing PPT, the teacher should pay more attention, grasp the center of the topic, then show it to the students in class, and then make some simple instant demonstrations with the blackboard, right? I think the teaching quality of this combination is the best. Of course, this kind of education also requires students to have corresponding configuration. For example, every student has a PDA or notebook computer, and the network in the classroom is not hindered.

PPT courseware is necessary, but it also has its shortcomings that cannot be ignored. It is no exaggeration to say that the content of a PPT class is worth two or three blackboard writing classes. PPT can save a lot of blackboard writing, teachers can spend more time, and the time saved can be used for teacher-student interaction, classroom integration, knowledge expansion and so on. The pictures and symbols in PPT are more intuitive, and the use of audio and video can increase the vividness and interest of courseware, so that students can learn in a pleasant emotional experience and improve the learning effect.

PPT courseware teaching can also make students fully imagine and understand, but compared with blackboard writing, it lacks the process of students' thinking and following, and the process of teachers' blackboard writing is also the process of students. Memory processing and PPT flashing animation can easily exceed students' understanding and memory ability. The best teaching mode should be the combination of modern information technology and traditional teaching, which lacks complementarity. Don't rely too much on PPT courseware, don't hesitate traditional teaching, seek a balance between the two, and combine them to improve teaching progress and quality.

No matter which method is adopted, it starts with the students' learning process, provides realistic, interesting and challenging learning materials, shows the formation and application process of mathematical knowledge, and aims to let children experience the thinking process from beginning to end. A good PPT is definitely icing on the cake. Above, dare to try, make continuous progress and encourage each other. Welcome everyone's encouragement and support. What do you think of this?
