The difference between educational all-in-one machine and projector (Part I)

1. Display projection: when using projector for teaching, the projector has poor adaptability to light. In class, close the curtains to reduce the brightness of the classroom and let the students see the projection clearly. The use of the all-in-one education machine optimizes the display of the display screen under different light intensities. It has optical anti blue light and anti glare functions, which can block harmful blue light and protect students' eyesight. The anti glare function can well adapt to the light and present the picture.

2. Intelligent writing: when using the projector, it needs to be used with computers, audio and other equipment. If a teacher wants to write directly on the courseware, he has to input it through a specific positioning pen or keyboard, which is very inconvenient. The all-in-one education machine has the function of intelligent writing. Teachers can annotate, modify and erase the teaching content directly on the screen with their hands or touch pen, which saves a lot of time and is very efficient.

3. Classroom quality: the interest and interaction of the classroom often determine the quality level of a class. When teaching with projectors, teachers often teach in the same way in class, and there are few scenes of interaction with students. The lack of interest and interaction in class also affects students' learning effect. For this part of the demand, the education all-in-one machine has rich teaching resources and question bank. When preparing lessons, teachers can make full use of these resources, or use the question bank to ask questions in class, so that students can think and answer, and their interest and interaction in class will be enhanced.
