Embedding active learning and design-based projects in a noise and vibration course for the undergraduate mechanical engineering program

Abstract

The content of noise, vibration, and harshness is an important part of the undergraduate mechanical engineering program education to prepare students ready for their future career, and it has received great attention from educators. Since course content in noise, vibration, and harshness usually requires more mathematical background knowledge and skills such as problem-solving in differential equations and linear algebra, students at the undergraduate level usually experience difficulty in the problem-solving work in noise, vibration, and harshness, though they have already completed the pre-requisite mathematics courses. In this paper, a new schedule and course content design for noise and vibration courses are introduced. By embedding active learning and design during projects, the students were able to obtain a better understanding of the concept of acoustics and vibration, as well as applying the knowledge from lectures to labs so they can connect the learning to real-world applications. Four projects are introduced and explained. To evaluate the effectiveness of the course, student outcomes are assessed and discussed.
