Critical Thinking: Is That Going To Be On Test, E Shirl Donaldson, Anne M. Lucietto

School of Engineering Technology Faculty Publications

The current generation of college students is a result of the “No Child Left Behind Act”. Educators at the university level are seeing the unintended result of high stakes testing in student attitudes towards learning and study. The K– 12 educational system in the US focuses on mastering tests and accruing points in a course, most often “teaching to the test.” These tests are standardized and critical to promotion and later acceptance into college. It is this activity that provides a basis for student perception of how learning and assessment take place. When these students are challenged with higher order …

Teaching Matlab And C Programming In First Year Electrical Engineering Courses Using A Data Acquisition Device, Phillip Wong, Branimir Pejcinovic

Electrical and Computer Engineering Faculty Publications and Presentations

Our industry partners often voice a complaint that our newly graduated electrical engineering (EE) students do not have sufficient programming skills. This is not a new concern. In a traditional undergraduate EE curriculum, one or two programming courses compose the entirety of the student’s training in programming. The courses may be taught by the computer science department without significant emphasis on engineering fundamentals. While the principles of computer science may be well covered, the ability to apply the knowledge to practical engineering problems is frequently lacking. To compound the problem, teaching novices the basics of programming can be very challenging …
