Improving Project-based Learning via Remote OPNET-based Lab Sequence in Undergraduate Computer Networking Curriculum

This paper presents the assessment results and findings of the National Science Foundation (NSF) sponsored CCLI project, entitled “Enhance Computer Network Curriculum using Collaborative Project-based Learning (CPBL).” During the first funding year, a cyberinfrastructure to enable remote project-based learning was established and a series of in-class and after-class projects using OPNET have been developed and implemented in CS470 and EE440, which were taught in Winter and Spring 2011 respectively. The content of CS470 and EE440 were also streamlined to cover the protocols and design issues of the entire network architect with minimum overlaps. To measure the impact of the course revision on student learning outcomes and to ensure the smooth implementation of CPBL, comprehensive evaluation using both direct and indirect assessment instruments was conducted. The assessment was collaboratively performed by the PIs and our external evaluator who is an expert from the College of Education. In this paper, both quantitative and qualitative assessment results will be presented and the collected data will be analyzed to show how well CPBL worked to enhance the student learning on various topics in computer networking. In addition, the lessons learned through the first year experience and the unique challenges revealed through assessment will be discussed. Through focus group conducted in Winter 2011, we collected a number of recommendations on how to improve the implementation of class projects and how to better integrate project-based learning and inquiry-based learning into a tight teaching schedule. Based on the assessment results and student recommendation, a plan has been devised to adjust the current teaching strategy and improve the effectiveness of online CPBL.
