Description
Technical Field
The invention relates to the field of remote education devices, in particular to a remote education device for education and training.
Background
Educational training is an organization or an online learning system that informationizes knowledge educational resources, which has been gradually developed in recent years. Typically, such institutions or websites will contain educational information at various levels, from preschool to university, and even for doctors or abroad. There are also specialized websites or training institutions that include skill training for workers at incumbent positions or for employees on the job side, which provide educational resources and training information as the primary content. Distance education, also called modern distance education as network education among some documents that the education department has already provided, is one of adult education calendars. The teaching mode is a teaching mode using transmission media such as televisions, the Internet and the like, breaks through the boundary of time and space, and is different from the traditional teaching mode in school accommodation. Students using this teaching mode are typically amateur repairmens. The student can attend classes anytime and anywhere because the student does not need to attend classes at a specific place. Students can also learn with the help of different channels such as TV broadcasting, Internet, tutoring special line, lesson and research society, and face-to-face (letter) etc. The method is a new concept generated after the modern information technology is applied to education, namely education developed by using network technology and environment. The student-attracting object is not limited by age and previous scholars, and the opportunity of promoting the scholars is provided for broad masses who step into the society. The remote education organization mode can be divided into: an individual learning mode and a collective learning mode, namely an individual learning mode and a team learning mode. The most important differences are: the team group teaching mode is based on synchronous communication, and teachers and students need to communicate in real time. The individual learning mode is based on asynchronous communication, creates a learning environment in the family of students, and the students can learn at a proper time. The two learning modes are essentially related to the mode of transmission and delivery of the educational resources
