计算机网络课程是计算机专业的一门重要的专业课。这是一门理论性和操作性都很强的课程,包含各种网络协议和网络设备,这些网络协议及网络设备的工作层面及工作原理不尽相同。如何根据中职的学生学习特点,让他们更好地理解各种网络协议和设备的原理,是教学中的重点和难点。目前对于网络协议和设备的教学,原则上都是基于Cisco品牌系列网络设备的。由于受到缺乏Cisco系列设备的硬件条件限制,以往教师通常以单纯的书本讲解或在其他品牌的网络设备上实际操作演示,学生很难理解其中各种设备的工作原理,缺乏学习兴趣,达不到学习效果。
Computer network course is an important professional course of computer science. This is a theoretical and operational course that includes a variety of network protocols and network devices that work and work at different levels. How to learn the characteristics of secondary vocational students, so that they better understand the principles of various network protocols and devices, is the teaching of the key and difficult. The current teaching of network protocols and devices is based in principle on the Cisco brand family of network devices. Due to the lack of hardware limitations of the Cisco series of devices, in the past, teachers often use simple books to explain or practice the demonstration on other brands of network devices. Students find it hard to understand the working principles of various devices, lack interest in learning, learning result.
