Design and Evaluation of a Web-Based Tool for Teaching Computer Network Design to Undergraduates

Previous studies have shown that motivating students to learn about local area network (LAN) design can be difficult when presented in the traditional lecture format. To overcome this problem, a Web-based tool (“WebLan-Designer”) was developed as an aid to teaching and learning of LAN design at introductory level. WebLan-Designer provides a set of learning resources (tutorials, quizzes, network modeling, network design scenarios, key terms and definitions, and review questions and answers) and aims to assist undergraduate students in learning the basics of both wired and wireless LAN design. The tool is Internet-based and can be accessed at any time so that students can study LAN design at their own pace and convenience. This flexible learning approach contributes positively to distance education and elearning using the World Wide Web. The effectiveness of WebLan-Designer was evaluated both formally and informally; positive student and peer feedback indicates that the design and the implementation of the tool has been successful and that using WebLan-Designer may have a positive impact on student learning and comprehension.
