Improving Learning in Continuous-Time Signals and Systems Courses Through Collaborative WorkshopsThe introductory continuous-time signals and systems (CTSS) course at the host institutionsuffers from drop/failure rates that are 2-6 times greater than other required electrical andcomputer engineering courses, which is a typical situation for most programs. We have receivedNSF funding to explore the sources of difficulty in such courses and determine effective methodsof helping students to learn the material. A major component of this project is to produce aworkshop that communicates pedagogical research results, gathers different perspectives fromother schools through focused discussion, and develops a broader community of interestedpedagogical researchers. By June, 2015, the workshop will have been offered five times, eachtime over a different duration from 1.5 hours to 3 days and with a varying audience. This paperdescribes the contents of the workshop, the experiences of the attendees, and the results ofinteracting with the various attendees.Regardless of the duration, the workshop is set up to address a series of questions: 1) Why areCTSS courses so difficult for students? 2) What can educators garner from learning theories andexperimentation to make CTSS courses more accessible for undergraduate students? 3) How canwe exploit conceptual learning theories to improve learning for conceptually difficult courses?4) What approaches were utilized to improve learning? 5) How can participants use what wascovered in the workshop to improve their own courses? The answers to the first three questionsare sought by promoting discussion among the attendees through presentation of historical data,analysis of student work samples, review of some relevant conceptual learning theories, andresults from research being done to identify student misconceptions and their sources. Question 4is addressed by demonstrating some hands-on application oriented learning activities that arebeing developed to improve learning in introductory CTSS courses. Finally, to address Question5, the attendees are given an opportunity to review the already developed activities in the contextof the discussion that occurred for the first three questions.After the five offerings as of September 2014, the workshop has been attended by approximately35 faculty members from almost as many different universities and two different industryrepresentatives. By sharing similar experiences about student difficulties in CTSS courses from awide range of institutions and curricula, a more complete picture of both the difficulties andsolutions to help students get past them is formed. For example, several new hands-on activitieswere developed by workshop attendees during the extended summer offerings. Several newperspectives with regard to conceptual learning theory were derived from offering the workshopand are now steering a Ph.D. dissertation study. Discussions have promoted and influenced aredesign of the hands-on laboratory sessions at Rose-Hulman. Faculty at a large researchuniversity were interested in collecting similar historical data to understand if changes that weremade to their curriculum were able to improve learning of CTSS concepts.
