Increasing demand on workforce for nanotechnology implementation has resulted in an exponential increase of demand on educational material and methods to qualify this workforce. However, nanotechnology is a field that integrates many areas of science and engineering requiring a significant amount of background knowledge in both theory and application to build upon. This challenge is significantly magnified when trying to teach nanotechnology concepts and applications at the undergraduate engineering level. A considerable amount of time is needed for an undergraduate engineering student to be able to design and build a useful device applying nanotechnology concepts, within one course time. This paper presents an actual experience in teaching hands-on applications in nanotechnology to undergraduate engineering students through an optimized model, within a normal course time. The model significantly reduces the time needed by undergraduate students to learn the necessary manufacturing techniques and apply them to produce useful products at the micro and nano levels, by ensuring that infrastructure and legwork related to the educational process are partially completed and verified, before the course starts. The model also provides improved outcomes as all its pre-course work is also tested with students working under different arrangements of professors’ supervision. The result is an optimized infrastructure setup for micro and nanotechnology design and manufacturing education, built with students in mind, to be completed within the frame of one semester course. The model was implemented at GVSU-SOE as the core hands-on part of a senior undergraduate course titled (EGR 457 nano/micro systems engineering). Students in the course were able to go through the design and build steps of different MEMS and NEMS products, while learning and utilizing cleanroom equipment and procedures. This was based on infrastructural arrangements by students preceding this class by a semester and working closely with the professors. Assessment was conducted on both sides of the model and results were collected for evaluation and improvement of the model.

As wireless communication carrier frequencies continually increase to respond to growing bandwidth demands, from hundreds of MHz (3G/4G) to dozens of GHz (5G), it would only be logical to postulate that the next step in this technological revolution would be to move to hundreds of THz, also known as visible light. This completely alleviates the carrier frequency induced bandwidth limitations while serving as ambient lighting. In this paper, a visible light communication setup capable of moderate bitrate serial communication with interference from ambient lighting will be presented. Furthermore, this paper proposes the implementation of a similar setup as a form of hands-on experiential learning for high school and undergraduate engineering students.

Designers in any industry need to understand the processes involved in making a part beforehand in order to communicate with technicians from trade schools and industry. Even a simple engineering drawing can often not be created due to process limitations (e.g., a perfectly drawn internal 90 degree angle in a CAD drawing does not occur in nature OR in a machine shop). This paper describes an affordable way to teach manufacturing to undergraduate engineering students and in the process provide them with hands on training in a machine shop environment. The goal here is not to create machinists, but to enable future Engineers to understand and talk with designers/machinists. The theme here is not to spend on expensive super machines but on simple machines as emphasized in the Toyota Production System. Students learn the techniques that let technicians produce perfect parts on imperfect, simple machines. The result for Auburn University has been an affordable laboratory that mutually supports undergraduate students, graduate research students, and the university as a whole.

Due to the pandemic lockdown, York University’s Fall 2020 offerings of a pair of 1st and 2nd year undergraduate engineering and computer science courses were heavily modified to accommodate a completely online approach to teaching. The objective was to maximize interactivity and hands-on elements while also providing a supportive and authentic learning experience. Class presentations were made asynchronous by uploading them to YouTube and superimposing H5P elements via our Moodle-based LMS. Our traditional laboratory equipment was replaced with inexpensive lab kits that were obtained from commercial vendors and shipped to students via the university’s Bookstore. All tests, quizzes and exams were eliminated in both courses. Instead, a specifications-based assessment approach was taken, with all students given the opportunity to achieve a B+ if they completed all the work in the class. Students who wished to submit a final project could do so for an opportunity to boost their grade to A or A+. Most intra-semester deadlines were removed, with material associated with the synchronous lab sessions being the notable exception. The resulting grade distribution and averages were similar to previous years inwhich we relied to in-person testing. The rate of A/A+ was 21% and 8%, while the failure rate was 13% and 3% , respectively, for the first and second year classes. Informal feedback from students, including those with academic accommodations, was nearly universally positive, with most acknowledging that their stress levels were lower, making the learning more manageable. En raison de la crise sanitaire et le confinement COVID19, deux cours d’ingénierie de 1`ere et 2`eme année de l’université York ont été modifiés pour s’adapter à une approche d’enseignement entièrement numérique. L’objectif des adaptations était de permettre aux étudiants d’apprendre du matériel technique de manière pratique et interactive sur internet. Les présentations en classe ont été rendues interactives et asynchrones en les téléchargeant sur YouTube et en superposant des ressources H5P via notre environnement numérique d’apprentissage Moodle. Nos équipements de laboratoire traditionnel ont été remplacé par des kits de laboratoire abordables obtenus auprès de fournisseurs commerciaux et expédies aux étudiants via la librairie de l’université. Nous avons éliminé tous les tests, questionnaires et examens dans les deux cours. Une approche basée sur les spécifications a été adoptée, permettant les élèves d’obtenir un B+ s’ils terminent tous les travaux de la classe. Les étudiants qui souhaitaient un A ou A+ devaient soumettre un projet final. La plupart des délais intra-semestriels ont été supprimés, le matériel associé aux sessions de laboratoire synchrones étant l’exception notable. La distribution des notes et les moyennes étaient similaires aux années au cours desquelles nous nous sommes appuyés sur des tests en personne. Le taux de A / A + était de 21% et 8%, tandis que le taux d’échec était de 13% et 3%, respectivement, pour les classes de premières et deuxièmes années. La rétroaction informelle des étudiants, y compris ceux qui avaient des accommodements scolaires, était presque universellement positive, la plupart reconnaissant que leur niveau de stress était réduit et que l’apprentissage était gérable.

How undergraduate engineering students define their success and plan for their future differs notably amongst students. With a push for greater diversity and inclusion in engineering schools, it is valuable to also better understand the differences in these areas among different students to allow institutions to better serve the needs of these diverse groups.  The purpose of this research study is to explore students’ definition of success both in the present and projecting forward 5 to 10 years, as well as to understand to what level students reflect on, and plan for, the future. The proposed survey instrument for the pilot stage of this research includes 56 closed-ended questions and 3 open-ended questions. Evidence for the validity of the research instrument is established through a mixed-method pilot study. This paper will discuss the survey instrument, the pilot study, and outline plans for the full study.

The success of engineering and design is facilitated by a working understanding of human thoughts, feelings, and behaviors. In this study, we explored how undergraduate engineering students included such human-centered and psychological concepts in their project documentation. Although, we observed a range of concepts related to design processes, teams, cognition, and motivation, these concepts appeared infrequently and superficially. We discuss how this analysis and approach may help to identify topics that could be leveraged for future human-centered engineering instruction.
