Principles governing energy transformations, transport and conversion, includinglaws of thermodynamics and thermal-science are all covered. The course is a junior-level,required course in the Energy Sector (one of six strategic sectors) in the Integrated Science andTechnology (ISAT) program at James Madison University. The course is considered one of thehardest in the curriculum and enrolls about 50 students each year.Course Learning GoalsThe five overarching learning goals are to enable students to: 1. Gain a thorough understanding of the basic definitions, concepts and principles of thermodynamics. 2. Analyze thermodynamic processes and
very useful for the instructors when theyillustrated related topics to the students throughout the semester.IntroductionStatics and particle dynamics is a sophomore-level course required by most engineering majorsat universities. Compared to the introductory physics classes, where the focus is on concepts, amajor element of these classes in the engineering context is on being able to bring multipleconcepts together for making qualitative judgements. It is quite challenging for many students torelate what is covered in class to how bodies actually behave, especially if they do notunderstand concepts correctly. It is then essential for instructors to know what commonmisconceptions students have and how to correct them. Clement [1] studied
learning. This coursetypically has 59-120 sophomore and junior level mechanical engineering students enrolled andhas been taught in a flipped format, using the SCALE-UP model (Beichner, 2008), for severalsemesters. By design, the course relies heavily on peer-to-peer instruction through cooperativelearning, and beginning in the semester of Spring 2016, the instructor aimed to move fromcooperative groups to high performing teams using principles of team-based learning (L. K.Michaelsen, Knight, & Fink, 2002). Three primary research questions were examined: 1) whateffect does the implementation of TBL have on individual student learning, compared to anoffering of the course prior to implementation; 2) what effect does the implementation of
capstone course.Capstone Program DesignOur design objective was to create a dynamic capstone program that fosters continuous studentpreparation and engagement beginning in the sophomore year. With the program, students arepresented with a spectrum of opportunities to interact with peers ranging from sophomores toseniors. Our intent was to instill a proactive and enthusiastic attitude towards the capstoneexperience and to develop strong collaborative ties between students at varied stages in thecurriculum. As illustrated in Figure 1, this framework depicts the capstone as an evolvingprogram rather than a single course in the senior year. Among the students and faculty, thisapproach is aimed at creating a common mindset of growth building to the
learning (PBL),and entrepreneurially minded learning (EML) into the engineering curriculum [1, 2, 3]. Activelearning requires students to actively discuss issues or work problems in the classroom, rather thanlistening passively to a lecture. If students informally assist one another in this process, thetechnique is deemed collaborative learning [4]. A related approach, problem-based learning,introduces engaging real-world problems for students to solve, usually as part of a group [5]. Anew twist on problem-based learning is the inclusion of student skills associated with anentrepreneurial mindset, such as integrating information from many sources to gain insight,conveying engineering solutions in economic terms, and identifying unexpected
for using modern engineering tools,specifically in the machine design process. This was accomplished by developing analysis-basedprojects that students code in a math computational program (typically MATLAB). Three ofthese projects were carried out throughout the semester in conjunction with an introduction to thedesign philosophy presented by the textbook by R.L. Norton [1]. The following manuscript (1)describes the rationale for the introducing the projects, (2) gives detail description of the projectsand (3) assesses the efficacy of the projects to achieve the objectives through results obtainedfrom a survey given to students during their senior capstone design course.1. Introduction and Background Machine design is a required
learn to think at the system leveland to look for relationships between design elements.The primary goals of our course were to combine a strong foundation in the analysis of machineelements with a realistic experience as a machine design engineer. This was done by presentinga conventional 3 credit course that is intertwined with a 1 credit laboratory. The lecture course isvery much a traditional class in design of machine elements. Students are introduced to oneanalytical method at a time and study the application of each method in depth. Evaluation ofstudent learning is done through traditional methods such as homework, quizzes and exams. Theselection of topics is similar to that of most design of machine elements courses.

sheet metal forming is mainly introduced in [1-2]. Formability isdefined as ability of sheet metal to be deformed plastically without any failure. In the recentyears, several studies have been conducted to characterize sheet metal formability [3-7]. Intoday’s industries, the demand for stronger material with high ductility and formability is high.The automotive industry is constantly looking for lighter material with improved materialproperties. Traditionally, the standard tensile test has been used to obtain information on stress-strain graph of materials under deformation. However, this test is limited because it onlymeasures uniaxial stress-strain behavior and is only useful up to the ultimate strength pointwhere “necking” is about to occur
).Introduction and brief literature reviewThere is no doubt that capstone courses are very important players of the final program outcomesof an academic department, and the university as a whole. Capstone courses provide ultimateacademic experience to students at the exit of their academic career. Capstone courses build upon the learning outcomes from majority of the courses they take as undergraduate level.According to Tomorrow’s Professor Postings on Teaching and Learning (Stanford University)[1], "Introducing [undergraduate] students to content that could make a contribution to their fieldhas potential benefits to the students, faculty, institution, and discipline. From the studentperspective, completing a research project with even the potential for

Phases 1 and 2 of the project asked students tocalculate/estimate the external loads acting on the input and output shafts of the gearbox. Inthese first two phases students were able to start experiencing a typical real-world situation inwhich, unlike textbook problems, the loads acting on the system were unknown and had to bedetermined. It required searching the internet, consulting textbooks, inspecting the Baja, andmaking assumptions. In the last phases, the students compared the results of their sizingcalculations to the existing components and applied critical thinking skills (discern the true

will have positive impacts on training and educatingstudents in areas of design optimization, computational, and simulation methods.IntroductionAccording to the Oxford Dictionary, the word “optimize” in a general setting can be defined asmaking the best or most effective use of a situation, opportunity, or resource without violatingany constraints. Modern optimization methods were pioneered by Courant’s paper [1] on penaltyfunctions, Dantzig’s paper [2] on the simplex method for linear programming, and Karush,Kuhn, and Tucker, who derived the KKT optimality conditions for constrained problems [3]. Theuse of nonlinear optimization techniques in structural design was pioneered by Schmit [4].Today, many engineering problems involved in design

Our experience indicated thatteaching the fundamental concepts of FEA theory significantly helped students to have a betterunderstanding of FEA application and to facilitate them to use FEA commercial software.1. INTRODUCTIONNo. 1 design criteria for mechanical design is designing safe components. It is well known thattheoretical calculations of stress and strain can be conducted only on components with simplegeometries under simple loading conditions. But, FEA (Finite Element Analysis) simulation cancalculate the stress/strain of components and assemblies with complicated geometries undercomplicated loading conditions. In the current industry practice of mechanical design, theprototype of design may not be manufactured for testing
introducing properties of water, allowing more time to be spent onpracticing thermodynamic analytical skills. This non-traditional approach, without steam tablesor online reference tools, also optimally aligned with the course learning outcomes.IntroductionDeveloping students’ fluency in determining thermodynamic state properties is a critical skillcommon to engineering thermodynamics courses regardless of specific instructional approach [1,-4]. When introducing thermodynamic properties, ideal gas properties are initially highlighted toleverage student familiarity with ideal gas concepts taught in prior chemistry courses. Beyondrecapitulating familiar P-v-T behavior and differentiating the mass- and mole-based forms of theideal gas law, initial
, mid, and long- term.Interest in pre-requisite knowledge in engineering While grades remain the primary overall indicator of student learning in a course, theconsideration of students' retaining of knowledge for deployment in post-requisite courses, andsubsequent experiences, is of interest in engineering education and related fields [1-8]. Theseefforts can provide insight not only on achievement of specific course outcomes by individualstudents, but by cohorts of students. Further, strategies for strengthening or reactivating suchprerequisite knowledge can be developed. Laman and Brannon [1] described a need to integrateprerequisite materials in a structural design of foundations course, utilizing electronic media suchas pencasts to
organizations thatpromote integration of art and science are Art & Science Collaborations, Inc. (ASCI),International Society of the Arts, Mathematics, and Architecture (ISAMA) and InternationalSociety for the Arts, Sciences, and Technology (ISAST). In academia, educators are alwaysexperimenting new methods to increase students engagement in the course materials. One sucheffort in fluid mechanics is a course on the physics and art of flow visualization, by Dr. JeanHertzberg (at the University of Colorado, Boulder) [1-3]. The course is offered since 2003 as atechnical elective to the engineering students and as studio credit to the fine arts students and hasshown to be very effective.

Craig,as a professor at Rensselaer Polytechnic Institute from 1989-2008, created the mechatronicsundergraduate and graduate programs there, and, in 1995, created the Mechatronics diagram(Figure 1), now used around the world to illustrate this concept.Design, above all else, defines the difference between an engineering education and a scienceeducation. Design represents the bridge between theory and reality. It is the process by whichour ideas enter and influence the world around us. Design distinguishes us as engineers.

original ambient pressure and will have to encounter an adversepressure gradient (low to high pressure) [1]-[3]. Even though air has a low viscosity, viscousforces will still exist near the airfoil surface due to the large velocity gradients, a result ofboundary layer. These forces will result in a reduction in momentum for fluid layers immediatelyadjacent to the airfoil. If these fluid layers do not have sufficient energy to overcome the adversepressure gradient, they will reverse in direction (see Fig. 1). The reverse streams will then collidewith the oncoming streamlines causing them to separate from the body and create a wake regionrich in vortices as shown in Fig. 2.

Specifically during the second offering of the online section in theSpring of 2019, the number of teammates in each team are reduced and additional projectmilestones are imposed to balance the teamwork over the duration of one semester.1. IntroductionClasses are taught within an engineering program in numerous formats. In general, these includelearning in a classroom, learning online, or a hybrid blend of the two. Regardless of the format,students taking a class are expected to meet the course’s educational outcomes. At thecompletion of a CAD class, which is the subject of this paper, students are expected to be able tocreate engineering designs and communicate the

vibration analysis courseBackgroundThe origins of mastery-based-learning (MBL) find a root in the idea that, with enough time, allstudents with the appropriate prerequisite understanding could master any new topic [1]. In atraditional grading scheme, all students progress through topics and the same rate. At the end ofa unit, an exam is used to assess student mastery. All students then move on to the next unitregardless of their performance on the previous exam.In a typical mastery-based approach, an individual student must demonstrate mastery of onetopic before progressing to the next topic [2, 3, 4, 5]. An MBL approach built upon a largenumber of tiered specific skills guarantees all students earning a particular grade in a course
courses incomposition and presentation, often being some of the first courses taken. This extends toengineering students, for whom effective communication is an important competency [1] and arequired criterion for degree accreditation (ABET - Student Outcome 3: an ability tocommunicate effectively with a range of audiences). The University of New Haven hasidentified writing skills as a priority and established Writing Across the Curriculum (WAC)initiative to support writing instruction throughout a student’s undergraduate career.In 2011, the College of Engineering at the University of New Haven carried out a survey ofalumni and employers to investigate the skills needed specifically of and by engineeringgraduates. From this, it became apparent
known as constraint-based CAD, allows users to capture design intent and totake full advantage of the desktop computer as a design tool. As a result, required courses in ComputerAided Design have become ubiquitous in undergraduate Mechanical Engineering programs.Typically, students are introduced to the basics of spatial visualization, the theory of variousprojection techniques and the preparation of engineering drawings, all the while mastering themechanics of using a particular software package. As with many courses in today’s credit-starvedcurricula, teaching a CAD course presents a unique set of challenges. Perhaps foremost is the varyingstarting abilities of the students [1]. Some may be distracted by computer graphics, trying to makeparts
the growing demand for online learning fueled by the generationallearning preferences.IntroductionAccording to USNEWS, more students have taken online courses than ever before and thatnumber continues to climb as more programs augment their on-campus offerings with onlinelearning opportunities [1]. Besides the obvious advantages, numerous studies have demonstratedthat online learning can have the same or better learning outcomes as face-to-face courses [2]. Areport on the emerging engineering education leaders identifies blended learning practices as acornerstone of these programs [3]. In fact, an argument can be made that instructors who teachan online course improve their teaching because every element of the online learning experienceneeds

To accomplish this, the paper contributes by (1) introducing examples ofspontaneous processes that most people should already understand, (2) providing a brief reviewof the general operations of heat engines and the Carnot cycle, (3) framing the Carnot cycle inrelation to entropy, (4) discussing non-ideal heat engines, (5) showing analogies to help thereader understand the significance of the ratio Q/T as a definition for entropy, (6) adding somebrief notes on entropy that are beyond the general scope of this paper, and (7) presentingbrainteasers designed to engage students in the classroom.
