Teaching and Learning Computer Networking

This section includes six chapters covering wired and wireless LAN design, communication networks and protocols. Chapter II introduces a Web-based tool called WebLan-Designer for class demonstration as well as modeling LAN  design. The tool provides students an interactive and flexible learning experience in designing wired and wireless LAN and improves students’ participation in learning activities. Chapter III describes another interactive learning tool called iNetwork that allows students to experiment with difference network onfigurations or build custom networks without the need for expensive equipments. The authors illustrate laboratory exercises with detailed process to demonstrate the usefulness of the tool in reinforcing and extending students’ understanding of network topics.

Following computer networking concepts, chapter IV presents the use of a network simulator called Packet Tracer in practical exercises to encourage independent and analytical processes and facilitate deeper learning. The simulation tool provides visualization, animation and meaningful intrinsic feedback features which engage students during the practical concentration and interest. Chapter V describes the architecture of a protocol animation tool called JASPER that provides a graphical and dynamic learning environment in communication protocols. This tool animates wellknown protocols and allows students to add new protocols. Students can gain real insight into protocol design, analysis and operation using the JASPER protocol animator.It is often difficult to motivate students to learn computer networking due to its dry and boring theories. herefore, chapter VI presents a framework based on a set of learning activities for enhancing teaching and learning various aspects of packet-forwarding theories and concepts. Through the framework and laboratory activities, teachers areable to liven-up lecture environment and students can gain insights into the concepts of packet-forwarding theories. Chapter VII emphasizes that students can view the abstract protocols as real artifacts that can captured and examined by using open source software called Ethereal. The proposed approach involves five activities, such as instruction, directed task, independent activity, novel situation and reinforcement. According to students’ feedback, the tool gives students the ability to develop a better understanding of network protocols and problem-solving skills.
