Physiology is a core requirement in the undergraduate biomedical engineering curriculum. In one or two introductory physiology courses, engineering students must learn physiology sufficiently to support learning in their subsequent engineering courses and careers. As preparation for future learning, physiology instruction centered on concepts may help engineering students to further develop their physiology and biomedical engineering knowledge. Following the Backward Design instructional model, a series of seven concept-based lessons was developed for undergraduate engineering students. These online lessons were created as prerequisite physiology training to prepare students to engage in a collaborative engineering challenge activity. This work is presented as an example of how to convert standard, organ system-based physiology content into concept-based content lessons.

<p>In addition to the engineering knowledge base that has been traditionally taught, today’s undergraduate engineering students need to be given the opportunity to practice a set of skills that will be demanded to them by future employers, namely: creativity, teamwork, problem solving, leadership and the ability to generate innovative ideas. In order to achieve this and educate engineers with both in-depth technical knowledge and professional skills, universities must carry out their own innovating and find suitable approaches that serve their students. This article presents a novel approach that involves university-industry collaboration. It is based on creating a student community for a particular company, allowing students to deal with real industry projects and apply what they are learning in the classroom. A sample project for the German sports brand adidas is presented, along with the project results and evaluation by students and teachers. The university-industry collaborative approach is shown to be beneficial for both students and industry.</p>

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.

Educating engineering students in the appropriate methods for analyzing and problem solving fundamental manufacturing processes is a challenge in undergraduate engineering education, given the increasingly limited room in the curriculum as well as the limited time and resources. Although junior and senior level laboratory courses have traditionally been used as a pedagogical platform for conveying this type of knowledge to undergraduate students, the broad range of manufacturing topics that can be covered along with the limited time within a laboratory course structure has sometimes limited the effectiveness of this approach. At the same time, some undergraduate students require a much deeper knowledge of certain manufacturing topics, practices or research techniques, especially those who may already be working in a manufacturing environment as part of a summer internship or part-time employment. The current work shows how modeling, actual machining tests and problem solving techniques were recently used to analyze a manufacturing process within a senior design project course. Specifically, an Instantaneous Rigid Force Model, originally put forward by Tlusty (1,2) was validated and used to assess cutting forces and the ability to detect tool defects during milling operations. Results from the tests showed that the model accurately predicts cutting forces during milling, but have some variation due to cutter vibration and deflection, which were not considered in the model. It was also confirmed that a defect as small as 0.050 inches by 0.025 inches was consistently detectable at multiple test conditions for a 0.5-inch diameter, 4-flute helical end mill. Based on the results, it is suggested that a force cutting model that includes the effect of cutter vibration be used in future work. The results presented demonstrate a level of knowledge in milling operations analysis beyond what can typically be taught in most undergraduate engineering laboratory courses.

The primary objective of this paper is to bridge the theory of tuned vibration absorbers (TVA) with the practice of implementing TVAs in systems. Often, the practice of implementing TVAs in systems is a far departure from the theory expressed in many textbooks. These departures are often required in practice to account for the less than ideal conditions that the TVAs will be operating under. Many retrofitted TVAs use “smart” or active materials along with various control techniques to improve the performance of the traditional TVA proposed in textbooks. The intent of the current paper is to demonstrate several of these modern methods of implementing retrofitted TVAs to undergraduate students. The first author introduced the methods in a junior level vibrations course, and is developing a laboratory experiment. Teaching these advanced TVAs to undergraduate engineering students will help them understand how theories learned in class are used in real world problems, and motivate them to explore new fields of research. After introducing a “textbook” vibration absorber theory, this paper describes principles and operations of a new class of vibration absorbers. In reviewing conventional TVAs, students are introduced to many of the engineering challenges encountered in the implementation of TVAs. One such challenge is inevitable off-tuning caused by system parameter changes with time. After identifying many of the challenges associated with the implementation of TVAs, the students are introduced to many modern solutions to these problems. Many of these solutions involve the use of smart materials, such as piezoceramics, magnetorheological fluids, magnetorheological elastomers, shape memory alloys, etc. Through this experience, students are introduced to many smart materials and have the opportunity to see how these smart materials can provide solutions to many engineering challenges and improve existing technologies.

This study explored the aspirations of undergraduate engineering students in regard to helping others, examining potential differences between disciplines and institutions. Over 1900 undergraduate students from 17 U.S. universities responded to a survey in spring 2014. In open-ended responses, 15.5% of the students included some form of helping people and/or the world as one of the factors that motivated them to select their engineering major; for 6.7% of the students this was the primary or only motivating factor listed. Helping as a motivation was not equally prevalent among different engineering disciplines, being much more common among students majoring in biomedical, environmental, materials, and civil and less common in computer and aerospace. Different disciplines also varied in the priority for helping people relative to other future job factors - highest in chemical/biological, moderate in civil and related majors, and lowest among electrical/computer and mechanical. Institutional differences were found in the extent to which students indicated an importance that their career would help people and the extent to which an ability to help others was a central message in their major. The results indicate the percentages of engineering students who are most likely to embrace humanitarian engineering; fostering these aspirations in students could help with attraction and retention.

This presentation will share the results of a longitudinal cohort study of undergraduate students matriculating through the UNC &amp; NC State Joint Department of Biomedical Engineering. Over the last few years, students in this program have participated in an experimental, specialized information literacy training program aimed at preparing them to navigate the labyrinth of business hurdles associated with medical innovation and entrepreneurship. This longitudinal study, led by two librarians, sought to determine whether an intensive, specialized information literacy training program could introduce undergraduate biomedical engineering students to the complex environment surrounding innovative design in healthcare and medical entrepreneurship in order to improve their design projects. In addition to discussing our study’s results, we will share our lessons learned from conducting this study and some possible implications for professional practice. We will close with a discussion of the challenges involved in partnering with an academic department to conduct formal assessments of student learning, and by sharing practical strategies that other librarians can use to identify opportunities to build similar partnerships at their local institutions.Originally presented at the Triangle Research Libraries Network (TRLN) Annual Meeting 2018 in Durham, NC on August 20, 2018.

A Review of: Phillips, M., Fosmire, M., Turner, L., Petersheim, K., & Lu, J. (2019). Comparing the information needs and experiences of undergraduate students and practicing engineers. The Journal of Academic Librarianship, 45(1), 39-49. https://doi.org/10.1016/j.acalib.2018.12.004 Abstract Objective – To compare the levels of information literacy, needs, and challenges of undergraduate engineering students with those of practising engineers. Design – Electronic survey. Setting – Large land grant university in the Midwestern United States and multiple locations of a global construction machinery manufacturing company (locations in Asia Pacific, Europe, North America). Subjects – Engineering undergraduates and full-time engineers. Methods – Two voluntary online surveys distributed to (a) students in two undergraduate engineering technology classes and one mechanical engineering class; and (b) to engineers in an online newsletter. None of the questions on the survey were mandatory. Because the call for practising engineers generated a low response rate, direct invitations were sent in batches of 100 to randomly selected engineers from a list provided by the human resources department of the company participating in the study. The surveys were similar but not identical and included multiple choice, Likert scale, and short answer questions. Data analysis included two-sided unpaired sample t-tests (quantitative data) and deductive and inductive content analysis (qualitative data). Main Results – There were 63 students and 134 professional engineers among the respondents. Survey response rates were relatively low (24.3% for students; approximately 4.5% for employees). Students rated themselves higher overall and significantly higher than did engineers on the questions “know where to look for information” (students M = 5.3; engineers M = 4.2) and “identifying the most needed information” (students M = 5.5; engineers M = 4.8) (mean values reported on a 7-point scale). Neither group rated themselves highly on “reflecting on how to improve their performance next time” or “having a highly effective structure for organizing information,” though engineers in North America rated themselves significantly higher than those in Asia Pacific on organizing information, knowing where to look for information, and using information to make decisions. Both students and engineers reported often using Google to find information. The library was mentioned by one-half of engineers and one-third of students. Engineers reported consulting with peers for information and making more use of propriety information from within their companies, while students reported using YouTube videos and online forums, as well as news and social media. More than half of students (57%) reported having enough access to information resources, while 67% of engineers felt that they lacked sufficient access. The most common frustration for both groups was locating the information (45% of student responses; 71% of engineer responses). Students reported more frustration with evaluating information (17%) compared to engineers (9%). Conclusion – Engineering students and professional engineers report differences in their levels of confidence in finding information and differences in the complexity of the information landscape. Engineering librarians at the university level can incorporate this knowledge into information literacy courses to help prepare undergraduates for industry. Corporate librarians can use this information to improve methods to support the needs of engineers at all levels of employment.

The major challenge in laboratory teaching is the application of abstract concepts in simple and direct practical lessons. However, students rarely have the opportunity to participate in a laboratory that combines practical learning with a realistic research experience. In the Biomedical Engineering career, we offer short and optional courses to complement studies for students as they initiate their Graduation Project. The objective of these theoretical and practical courses is to introduce students to the topics of their projects. The present work describes an experience in electrophysiology to teach undergraduate students how to extract cortical information using electrocorticographic techniques. Students actively participate in some parts of the experience and then process and analyze the data obtained with different signal processing tools. In postlaboratory evaluations, students described the course as an exceptional opportunity for students interested in following a postgraduate science program and fully appreciated their contents.

Design is seen as the magic word and being a design engineer is considered to be the key to success in the job market by many of the mechanical engineering students. However, it is always assumed that the mechanical systems not the thermal engineers are indeed design engineers by education and practice. This notion probably stems from the fact that most of the thermal fluid courses in mechanical engineering curriculum seem to have been defined and developed to prepare undergraduate students for going to graduate school rather than the job market. The undergraduate courses usually emphasize on the theories with less attention to the design and application aspects. Perhaps, the responsibility of thermal engineering educators is to correct this notion by emphasizing more on the application and design in the existing courses or alternatively to develop and offer new courses on more applied topics. In this paper, we will report an integrated approach in teaching topics in fins and fin assemblies, which includes class lectures, laboratory experiments, ANSYS simulations and design competition. In this manuscript, we will report on the details of this approach including the procedures, methods, our observations, and the students’ feedbacks.

Developing engineers with entrepreneurial skills is becoming a valued objective for engineering faculties across the country. Entrepreneurship courses are being added to engineering curriculum, course options are being created to allow students to pursue an entrepreneurship or management track in their undergraduate engineering studies, and graduate programs are being developed in Engineering Management, as a more specific and alternative route to the Master of Business Administration (MBA). This paper presents the results of a six-year survey of engineering students who have elected to enroll in an upperclassmen Entrepreneurship course. It presents the approach that has been taken in an Engineering elective at Memorial University to develop entrepreneurially minded engineering students, and the students’ perspectives on why engineers become entrepreneurs, what entrepreneurial qualities they believe they possess, and how they have learned to evaluate entrepreneurial ideas not only on its technical merit, but organizationally and strategically.
