As reported by the ASME Center for Education Task Force [1], human health will be one of the major areas in which mechanical engineers will take the leadership position to develop innovative technologies in the future. To adapt to the transforming role of the mechanical engineering profession, undergraduate education of mechanical engineering needs to guide students to apply engineering principles in this area. In this paper, the development of an undergraduate biomedical course in a mechanical engineering major is introduced. Several course projects developed by mechanical engineering undergraduate students are described. These projects focused on the study of biomedical problems using engineering problem solving skills. The projects were started with the analysis of injuries or diseases of patients. Then, injuries and/or possible treatments were analyzed from the viewpoint of a mechanical engineer. All of these students’ projects are summarized in this paper and a few projects discussed in detail. Among these projects, the flow and pressure distributions of different types of heart valves were calculated using computational fluid dynamics; the consequence of injuries of joint cartilage was analyzed with bearing design theory; the treatment of a muscle hernia was calculated using the finite element method. These projects encouraged students to appreciate engineering applications in fields other than traditional fields such as automobile and aircraft design. The results of the projects are also useful in practice. The course model is applicable for engineering programs in other small teaching universities.

Undergraduate Research Experiences

Undergraduate research experiences, which are highly promoted and supported by NSF and other agencies, present a great opportunity for our students to learn essential problem solving skills. The National Science Foundation’s Research Experiences for Undergraduates (REU) program is one of the largest initiatives supporting active research participation by undergraduate students in all of the areas of research funded by NSF. The REU program, with more than 600 sites around the world, presently funds over 1000 active awards, totaling over $327 million. From these active REU awards, 384 (38% of the total active awards) are related to engineering (determined by having ‘engineering’ as a keyword in the title and abstract) and account for about $170 million, about half of the total amount of awards to date. In spite of such widespread support and belief in the value of undergraduate research, limited well-grounded research and evaluation studies exist [1]. Most of the existing literature reveals the predominance of program descriptions, explanation of models, and evaluation efforts, rather than studies grounded on research. Only recently have research and evaluation studies focused on assessing the benefits of undergraduate research [1–8]. Some of these benefits are (a) retention for underrepresented groups, (b) increased interest in the discipline, (c) gaining critical thinking skills, (d) increased self-confidence, and (e) clarification of career goals. Moreover, most of these studies on undergraduate research have focused on the sciences, whereas undergraduate research experiences in engineering have been understudied.

Symbolic Calculations

Symbolic analysis is one of the most feared tasks for many undergraduate students in engineering disciplines. Students argue that, without numerical values, it is difficult to make a sense out of a long expression. Instructors have experienced that students are diffident in such analyses; and they quickly lose interest in the topic. This trend has been enhanced with more prevalent use of computers in engineering curricula in recent years. In the senior level Mechanical Vibrations course, this author has experimented with an innovative procedure of using mathematical software such as MATLAB to enhance the students’ learning experience with extensive symbolic calculations. In this experiment, MATLAB is used as a rudimentary plotting device that allows students to plot curves. The procedure provides students a systematical approach to produce parametric plots from an analytical expression, and to validate the expression on physical grounds. This innovative procedure has changed students’ perception about long expressions, decreased their fear, and boosted their confidence in their analytical skills. All these help student to develop a more positive altitude towards symbolic analyses.

Design Competition

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.

Design And Construction

Teaching senior design courses and labs has not been an easy task for the two authors. It has been rather a daunting working task associated with great learning experiences. It was decided early on from the initiation of the mechanical engineering program at the McCoy School of Engineering at Midwestern State University that the senior design project within the senior design class is a testing and enriching experience for senior mechanical engineering students as well as the teaching faculty. The senior design course and labs are conducted as a research experience for undergraduate students and their assigned faculty. The proposed senior project spans over two semesters, fall and spring, where the students experience a full mechanical engineering related project from the inception phase, through the design and construction phases, and finishing with the testing and analysis phases. The inception phase stands essentially for the brainstorming phase where the students are required to come-up with a set of diverse solutions to their assigned project problem. The design and construction phases stand for choosing an optimal particular solution for their problem according to a set of defined criteria. Then, the students start the preliminary design phase with related cost estimation, and then finalize the design with a set of final drawings. After the design phase, the students start building a machine, an apparatus, a prototype or putting together the elements of a process. In this period they work intensely, with their faculty, the purchasing department, and mostly the department machinist, or the surrounding town machine shops. The testing and analysis phase stands for designing an experimental set-up, writing a testing procedure, and obtaining real time recorded data and proceeding with its analysis. In this technical paper, the authors talk about the requirements for a senior project known as the deliverables, the teaching tools used throughout the class work and labs, the students’ partial and final PowerPoints presentations and weekly and final reports. The authors describe the students overall achievements, and the archiving of the projects. Additionally, the authors talk about the twists and turns encountered during a senior project, with students, other faculty, the machinist, the lab technician, the secretary, and suppliers, and other difficulties experienced in running a full project with real final products. Finally, the authors talk about the aftermath of a senior project, eventual publications related to the project, and what is the view point of the American Board of Engineering and Technology (ABET) on these senior projects.

An important consideration in higher education is that graduates meet or exceed the program outcomes (POs). While there exists anecdotal evidence that the use of modern tools i.e. computer modelling and simulation, improve attainment of these outcomes, there is little empirical research available. Where empirical evidence is available, the variables considered would almost certainly have a bearing on the outcomes. In this work, the attainment of the POs by undergraduate engineering students in courses with and without the use of modern tools, based on quantitative data, were compared. It was hypothesized that courses using modern tools would lead to better overall attainment of POs, compared to courses not using these tools. As a case study, the PO attainment of students in the Mechanical Engineering undergraduate program at Universiti Teknologi PETRONAS (UTP) was considered. Quantitative data obtained through UTP's outcomebased education (OBE) software was used to assess the overall attainment of the POs for all courses for a cohort of 126 Mechanical Engineering undergraduate students class of 2017. It was found that, for the case study considered, the usage of modern tools has led to slightly better attainment of some POs, with slightly poorer attainment in other POs. Specifically, attainment in POs where the cognitive or the knowledge domain is more dominant improved, as the usage of modern tools helped students to understand theoretical concepts better. Attainment in POs were the affective domain is more dominant recorded a slight decrease, and the incorporation of modern tools did not aid in the attainment of these POs. The study is at a preliminary stage and a more detailed study, involving more cohorts, is planned to establish a correlation (if any) between the use of modern tools in higher education and attainment of POs.

The University

A delocalized international team of Graduate and Undergraduate students conceive, design, implement, and operate a 3 meter wingspan aircraft with the intent to investigate numerous new ‘green’ aircraft technologies. The project, known as Hyperion, teaches essential systems engineering skills through long-distance design collaborations with multidisciplinary teams of engineering students located around the world. Project partners are the University of Colorado at Boulder, USA, the University of Sydney, Australia, and the University of Stuttgart, Germany. The teams on three continents are distributed 8 hours apart; students can relay select work daily so that progress can “Follow The Sun (FTS).” As a result three workdays are packaged in one 24 hour period. The student teams operate as a single, independent entity; structuring themselves as a simulated industry operation. Thus, project management and systems engineering principles are learned through a real-world design and deliver experience. The project also teaches delocalized manufacturing: select components are manufactured by each team and integrated both in Stuttgart and Colorado, giving the students an opportunity to learn multifaceted design for manufacturing. The project incubated many problems which lead to mitigation techniques for global collaboration as well as generating a better educated workforce to enter modern industry.
