Abstract

Engineering educators use MATLAB in multiple disciplines. The new features of MATLAB, such as MATLAB Grader and live scripts, can help students gain not only skills of analysis and design with MATLAB as a tool but also a better understanding of engineering concepts. MATLAB programming exercises are required in homework in a Vibrations course and computer lab projects in a Signals and Systems course. Automated grading with MATLAB Grader provides immediate feedback, which allows students to learn from their own mistakes while they try to pass the multiple requirements for each exercise that the instructor configured in advance. MATLAB live scripts are used in the teaching of Signals and Systems. Students are provided with lab manuals written in live scripts, allowing the integration of formatted text, equations, images, and MATLAB code in a single environment. With the live scripts, the concepts related to the MATLAB programming exercises are reinforced without the need of referring to another document or PowerPoint slides, and the examples embedded in the document can be run section by section with results displayed below the code or in an output window next to the document. Interactive components, such as a slider bar to change the value of time t in the convolution integral procedure and animation of the approximation of a signal using Fourier Series, are included in the examples to further improve the student learning experience. The instructor also used MATLAB live scripts during their lectures. At the end of the semester, the students completed a survey about their experiences with MATLAB Grader and live scripts. Students found these tools helpful in learning Vibrations and Signals & Systems. Setting up the auto-grading system was more effort in one semester than grading the work but will result in a reduced professor workload in future semesters.
