现如今中等专业学校普遍开设了计算机网络专业,但是在教学中普遍存在重理论、轻实践的现象,很大一部分原因是经费少,路由器、交换机、防火墙等常用网络设备严重匮乏。PacketTracer软件的引入教学极大地缓解了这个矛盾,让学生可以在软件环境下先进行网络学习、实验训练,然后再进行实际设备的操作,继而能进行全面的网络组建的训练,收到良好的教学效果。
Nowadays, secondary vocational schools generally have computer network major. However, there are common theories and practices in teaching. A large part of the reason is the lack of funds and the serious lack of common network equipment such as routers, switches and firewalls. The introduction of PacketTracer software greatly alleviated this contradiction so that students could conduct network learning and experiment training in the software environment before conducting actual equipment operation, and then be able to conduct comprehensive network formation training and receive good teaching effect.
