Product advantages:
Electronic class card is the basis of digital campus and smart
campus system. Digital campus is built on the basis of the network.
It uses advanced information means and tools to realize the
digitalization of environment, resources and activities. A digital
space is built on the basis of traditional campus to expand the
time and space dimension of the real campus, improve the efficiency
of traditional campus, expand the functions of traditional campus,
and finally realize the comprehensive informatization of education
process, So as to improve the level and efficiency of education
management. Digital campus is a concept that develops with the
change of technology application. It is the product of the
development of school education informatization to a certain stage,
and the inevitable result of transforming and upgrading the
traditional campus through technical means.
Smart class card system is an intelligent interactive terminal,
which is based on Internet of things technology. It integrates
intelligent teaching, student attendance, information release and
interaction between teachers and parents, as well as parents and
students. It is also one of the data collection tools of smart
platform.
Campus digital intelligent electronic class card (smart class card)
is one of the systems of campus culture construction and digital
construction. Each classroom is equipped with a front-end class
card integrated machine, which is generally installed at the door
of the classroom or in the classroom, and is mostly used to display
class information, current course information, class activity
information and school notice information. The information content
includes text, pictures, multimedia content, flash, etc., which
provides a new platform for students and teachers to communicate
with each other and provide campus service.
The E-Class signs strive to create a campus information release
window, a class culture construction window, and a classroom
teaching feedback window. We should give full play to the role of
moral education in the construction of class culture. At the same
time, we should give full play to the radiation and penetration of
electronic class cards, replace the functions of blackboard
newspaper in some classes, apply and popularize scientific
knowledge, broaden students' horizons, and improve students'
management ability, inquiry ability and information literacy.
Electronic class card network topology seamless link transmission
of campus information, electronic class card as a class culture
display and exchange window can be like an open window, let more
people see the class style, campus information construction
combined, timely transmission of campus information. Students can
also see the recent important events released by the school through
the electronic class board, and can also participate in the reply,
so that students can timely grasp the campus and class dynamics. At
the same time, it also publishes the current curriculum
information, class activity information and school notice
information.
The electronic class card is not only a display platform, but also
a communication link between teachers and students. In the past,
teachers told students to listen. However, it is difficult for
students to give timely feedback on their understanding of
classroom teaching. The electronic class card has the function of
classroom teaching feedback. Students can give feedback in time and
give class feedback to the courses they have. Teachers can
understand the feedback in time and adjust the teaching rhythm.
Class transparent management, electronic class card has
high-definition, interactive data sharing applications, data
real-time transmission to the campus and parents mobile phone.
Teachers can also log in quickly, with clear authority, combined
with attendance, sign in. The functions of electronic class card,
general branch school management and other functions are also based
on hierarchical authority management, to achieve self-management of
class teachers and students, or unified management of the school.
