(1) is light, environmentally friendly and easy to carry. The weight of electronic schoolbags can be controlled within 1000g, which greatly reduces the weight of students' schoolbags and is very convenient to carry. In addition, the use of e-books can greatly reduce the use of paper, effectively reduce the felling of trees and environmental pollution.
(2) Rich in content, flexible and vivid. The e-books in the e-book bag are not only the digitization of paper textbooks, but also the functions of reading, commenting and emphasizing. They can also create vivid and vivid teaching situations in multimedia forms such as sound, video and animation, which are more abundant than traditional books. E-book package is a teaching resource package formed by integrating several e-books according to a scientific structure. Including teaching materials, teaching AIDS, reference books, etc. , targeted, timely feedback and guidance, can independently generate massive exercises, can accumulate problems in time, collect wrong questions and update resources. E-books can also be saved by mobile storage devices, and we can easily carry a large number of books, even a library, when we go out.
(3) Enrich the teaching mode and content. The biggest significance of e-book bag is not to replace traditional teaching tools, but to change the existing ecology of teaching and learning. In the past, it was difficult for teachers to understand students' learning progress and understanding ability one by one, but by recording and analyzing students' learning process by computer, teachers can carry out personalized teaching and reach the realm of "teaching students in accordance with their aptitude". Many students don't express their learning problems and difficulties clearly in class because of shyness or face problems, which leads to a gap in learning progress over time. For example, teachers can chat privately through e-books, understand the learning situation and give individual guidance. Students download the classroom teaching process of the day into the e-book bag and practice it repeatedly at home so that they can catch up with the teaching progress in class the next day.
(4) Without "logistics", it is most suitable for e-commerce, and there will never be a problem of insufficient printing. The process of traditional books from production to consumption is "author, publisher and reader". E-books can greatly simplify this process and become a "direct selling" model for "authors and readers". After the author's work is completed, it becomes an e-book through simple operation, and then the e-book can be presented to the reader in an instant with a click of the mouse.
To sum up, the biggest advantage of the emergence of electronic schoolbags should be to encourage students to use information tools for autonomous and personalized learning, realize information interaction between teachers and students, and change the existing learning methods.
