Advantages and disadvantages of point reading pen:

Benefits: It is helpful for learning foreign languages and small languages, and it is more convenient to follow than tape drives and repeaters long ago. It is suitable for parents with weak foundation to exercise their children's hand-eye coordination and concentration by keeping them away from the electronic screens of mobile phones and computers.

Disadvantages: First of all, electronic products without screens are also electronic products. Individual children will rely on reading only, and the beautiful pictures that parents and children read will be taken away by machines, which is suitable for young children. Older children can read independently, so it is necessary to use less reading pens.

The point reading pen is not conducive to the development of senior high school students' brain, thinking, eyes, coordinated active reading and discovery and verification ability. As an occasional auxiliary dictionary tool, it is best to use it with parents. Don't leave it to children, otherwise it will not achieve the learning effect, but it will be harmful. Whether you use a pen or not, childhood companionship is the most important thing.
