Demand analysis
At present, education departments all over the country attach great importance to information technology education courses in schools, so the construction of electronic classrooms has become the first content of school education informatization. It should realize the following functions:
1. Teaching modernization
The use of electronic classrooms for information technology education enables teachers and students to experience modern information technology at the same time, making the course more real, vivid, easy to teach and easy to understand. Realize the transmission of sound and image, give students better sound visual effect, and make classroom teaching more vivid. The unique interactive function of electronic classroom and the fully embodied teaching concept of "two courses" can stimulate students' interest in learning and achieve good teaching results. The electronic classroom has the function of computer room management, which helps teachers to carry out modern electronic management of the computer room.
2. Enjoy resources * * *
With the development of information technology, it is possible to enjoy resources. Teachers and students can quickly find the vivid information they need for teaching or learning, which is conducive to understanding and mastering knowledge, broadening their horizons and improving their abilities.
3. Learn Internet knowledge effectively.
With the rapid development of the Internet age, people gradually cannot live without it. As the necessary talents for future social construction, students at school must also master and be familiar with cutting-edge technologies, especially technologies that are inseparable from work and life, which requires students to learn Internet knowledge during their school days.
network topology
Due to the problems of funds and conditions, the school can't afford a lot of internet access fees. If all students are allowed to surf the Internet, it is difficult to control what websites students go to, and whether it is beneficial to their study and growth. As a part of modern science and technology, it is necessary to impart Internet knowledge to students.
scheme design
Design ideas (taking 50 users as an example)
E-classroom is not only a good and smooth network environment, but also a multimedia e-classroom platform software that enables teachers and students to communicate, guide and control each other. With such platform software, teachers can play and relay screens and sounds to students, and teachers can remotely control students' computers, making teaching more convenient. This part of the function is realized by Lenovo Legend Internet Electronic Classroom (multimedia version or all-digital version). However, only multimedia electronic classroom platform software, without teaching resources and teaching content, still can not meet the needs of teaching. In the network environment, teachers and students should also be provided with a lot of resources to facilitate their teaching and self-study, so Lenovo Legend Education Teaching Resource Library can be used to help realize it. In a good and smooth network environment, students must master Internet knowledge. However, considering the actual conditions of the school and the controllability of students' learning content, the Lenovo Legend Internet simulation teaching system not only solves the problems that plague the school, but also fully simulates the Internet environment, which is realistic and safe. Resource sharing and internet knowledge in the system can also help teachers to better realize the teaching of students.
In terms of hardware, in order to meet the good transmission of images and sounds in the electronic classroom, combined with the actual financial situation of the school, it is suggested that the 50-minute electronic classroom should use teachers' computers and 50 students' computers, each with an earphone, and the network equipment should use switches, which are designed as 100M to the desktop. Teachers can use Lenovo 7-day 4000, students use Lenovo 7-day 2000, headphones use Lenovo Legend headphones, servers use Lenovo Wanquan 1600B, and switches use Lenovo D-Link 1624 switches. The network design of 100M can not only ensure the efficient transmission of the local area network in the electronic classroom, but also has good expansibility and is convenient to connect with the whole campus network.
