Universities are examining a variety of alternatives to the traditional teaching method of lecturing to students, many of which utilize technology to enhance or expand the traditional lecture experience. For classes with large enrollments that have a significant portion of the material that does not change from semester to semester, recorded lectures is one alternative to repeating the same live large lectures.
Based on a single set of core content-recorded lectures this work examines the effectiveness of two formats of delivery of the same material for students: 1) Online - where students watch online lectures and can attend online or live office hours or utilize the online course discussion board for help 2) Flipped classroom - where students watch the lectures online and spend time in class with hands-on learning and problem solving with a faculty member. Because both categories of students, “Online” and “Flipped Classroom”, watch the same lectures and complete the same assignments, there is an opportunity to compare the effectiveness of the two delivery methods.
This work examines the effectiveness of the two delivery methods in an Elements of Electrical Engineering course, where 250 engineering students who are not majoring in electrical engineering, learn about circuits, motors, AC power, and Op-Amps. The ratio of online students to flipped-classroom students is approximately 110 online to 140 flipped-classroom. The hands-on aspect consists of building Arduino circuits that complement the material presented in class. Flipped-classroom students build the circuits in the classroom in sections of less than 50 students, with the support of instructors and other students, whereas online students work at home, with optional live and online office hours and then must record a video of the working circuits and submit it for grading. Both online and flipped-classroom students are required to submit a final open-ended design challenge project using their Arduino based circuit kits, which is 10% of their final grade.
Metrics in this study to compare the online and flipped-classroom students are based on the Arduino builds. This work will examine the final circuit-design reports and videos for both categories of students against a rubric designed to rate the complexity, student understanding, and communication of the function of the Arduino based projects. Students in both categories are also surveyed for self-reported comparison of their comfort level and understanding of the Arduino builds.
