Under the current situation, the school is delayed. No matter for schools, education and training institutions, or students, online education and online classes have become an alternative. However, for both teachers and students, the experience of online class is not so good.

(DTEn for drawing, the same below)

In fact, online class is not a new thing. Many educational institutions, such as New Oriental and elite, have online education business for a long time, but their offline business is still the source of income accounting for more than 90%. There is still a lot of room for the development of online education. This also explains from the side: the network course is not the best choice of learning, face-to-face teaching is the best way of learning under the practice of the masses. If it is not a special period, no one would like to have classes at home facing the screen.

Then, we have to accept a setting: the online class experience is really worse than sitting in the classroom. But if the online class is not good, it is not only the educational institutions headed by the school, but also the vast number of students and parents who are affected. So what’s the difference between online education and sitting in the classroom? What is mentioned most is the interaction of classroom and the concentration of teachers and students. These two points are the disadvantages of online courses. And the most critical point is the most insurmountable gap between online classes and classroom classes. In fact, blackboard writing is the soul of classroom classes.

Remember when you went to school, all the knowledge points were written on the blackboard by the teacher, while they were written into your brain. It is also the teacher who writes and talks on the blackboard, which can not only effectively interact with teachers and students, but also ensure that students can pay more attention to listening with eyes and ears. In the classroom, the teacher’s blackboard writing is interesting and clear. However, blackboard writing in online teaching is very limited.

Traditional blackboard writing vs online teaching blackboard writing

Teachers have limited access to the Internet. Many teachers take classes through computers, mobile phones or tablets. The device screen limits the blackboard writing in the process of online class. Many teachers can only use the mouse to write, with a stylus or tablet in a better condition, but also can only write on the mobile phone or tablet screen cautiously. So most of the online classes can only guarantee oral expression, it is difficult to achieve blackboard teaching.

Traditional online course equipment

Now there is such a product, which is necessary for online classes, making the experience of online education “big” different. That is DTEn D7 artificial intelligence interactive large screen.
