. Students focus on practicing simplified engineering problems by solvingequations without understanding the real reasons for certain material behavior at the macro scale[1-3]. It is necessary to help students connect their learning in materials with mechanics at differentscales to improve mechanics education.Due to the current excitement about additive manufacturing, we focus on additively manufacturedmetallic materials to provide a solid platform for engineering analysis of length scale effects onmaterials properties. Our goal is to design and experiment with new approaches to help studentsunderstand the relationship between material structure, processing, and properties. In contrast toconventional and subtractive manufacturing methods, additive

One of the greatadvantage of these courses is the potential diversity among the students which can offer muchwider level of insights and discussions in the class which if guided appropriately can lead tocollaborative learning environment and have the potential to incorporate the concepts of industry4.0 [1] in curriculum. These technical elective courses also provide opportunity for

As a result, studentsare acquainted with calculation requirements/procedures, design considerations, potential sourcesof failure, and cost reduction factors.I. BACKGROUND AND MOTIVATIONThere are various teaching pedagogical approaches that have been identified to enhance studentcomprehension and scholarship abilities in engineering education. One of the most recurrent isknown as Problem-based learning (PBL), which is centralized towards the acquisition ofknowledge and primarily focuses on developing learners’ self-directed learning capabilities andcritical thinking-skills through problem-solving, interpersonal skills, and team skills [1]. As such,intricate

The7E plan consists of 7 sequential stages in teaching and learning that are elicit, engage, explore,explain, elaborate, evaluate, and extend [3]. The 7E model is often used as a conceptual changemodel. This model seems to be a complete and comprehensive teaching tool that initiates witheliciting the interests of the learners and ends up at the future extension of the concepts, and thestages can also be repeated in cyclic order. Within its levels, instructors can work from elicitingdissatisfaction at the beginning to having students extend their new understanding to ensure themisunderstanding has been
students have a plethora of distractions available to them. If students feel boredor frustrated with the material, often times they will browse the Internet on their laptops or pullout their phones. They learn differently, more visually and intuitively, and they have shortattention spans. To make them pay attention in class, the material and presentation methodsshould be visually clear, intuitive and engaging. This paper focuses on a visual, example-based, and engaging approach to teaching aspecific Statics concept, namely center of gravity. To teach this concept, the paper sharessupplemental materials that can be introduced during instruction. The paper introduces thisconcept using (1) daily, experience-based examples, such as an elephant

Based on theories of visual awareness[1], one way to involve the higher cortical areas of the brain needed for learning, is throughdirecting attention to an image. Directed attention is key in this process. While watching animage or video in passing does stimulate the visual cortex, without directed attention, it will notstimulate the higher cortical areas. This is the reason why watching an educational video whilebeing engaged in other activities at the same time usually doesn’t lead to deep learning.However, directing

To break this cycle, thispaper looks at the use of doodling to provide a different mode of content engagement.The use of drawing to create an alternative method for displaying and retaining information has anumber of supporters. Ainsworth et al [1] suggest that incorporating drawing into scientificeducation can produce increased engagement, improved reasoning, better organization, andbetter communication of concepts, among other benefits. Andrade [2] demonstrates thatdoodling provides a contrasting form of engagement that can increase attention and retention ofinformation.

Future work, notaddressed in this work-in-progress, will further evaluate the effects of including microprocessorsin these classes by examining student survey data as cohorts move through the newlyimplemented curriculum. Evaluating the use of relevant systems in senior capstone projects bothbefore and after implementation will provide particularly meaningful assessment.1 IntroductionThe advent of inexpensive, easily-accessible microcontrollers, such as the Arduino, has openednew opportunities for integrating hands-on activities related to sensors and mechatronic systemsinto the mechanical engineering classroom.

material, students often times do not spend an adequate amount of time outside ofclass reviewing the material. This lack of perquisite knowledge leads them to start learning newmaterial on a weak foundation. As the semester progresses and the material builds, these studentsare more likely to fall further behind, which can place them in jeopardy of failing the class.This project seeks to improve students' recall and mastery of prerequisite knowledge andultimately decrease failure rates, by creating an accessible library of short videos on various MEprerequisite topics. The review videos are currently being implemented in 3 ME courses (1required undergraduate course, 1 undergraduate technical elective, and 1 graduate level course)in Spring 2019 at
).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.

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.

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

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

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

The results can guide the educators and education decision makersto adopt appropriate technologies especially robotics as pedagogical tools to enhance the teachingand learning outcomes and effectiveness. The limitations and future directions of the research arealso discussed.1. IntroductionBased on years of teaching experiences of undergraduate mechanical engineering courses, it isrealized that there are many mechanical engineering concepts that are fully or partly abstract innature. For example, torque, moment, pneumatics, hydraulics, etc. It is experienced that studentsusually feel difficulty to comprehend such concepts when they are taught such concepts intraditional classroom settings. The difficulty level becomes higher
through the use of commercial finite element method(FEM) software and 3D printers have become common tools to reverse engineer and developlighter products in the industry. Reverse engineering is a process in which the starting point ofa new design starts with an existing design [1]. These tools were incorporated into a designcourse in a Mechanical Engineering program to design and validate a lighter version of abracket.3D Laser scanners are used to obtain the geometry of existing parts determining the position ofa scanned area by sensing the reflection of a laser on a surface taking into account the period ofreturn of the light ray and the angle of impact [2]. The points obtained during the scanningprocess are used to form surfaces that can be
Taxonomy [1]. This goal is oftenachieved by developing the student’s ability to solve problems [2]. Concepts are more deeply understoodby applying them to solve problems in a variety of contexts. Therefore, textbooks typically contain asignificant number of example problems and practice problems, instructors utilize class time to workthrough example problems, homework often involves the student practicing problem solving skills, and asignificant amount of tests and final exams are typically devoted to assessing the student’s ability to solveproblems. Instructors typically agree that homework is an effective tool to help students develop a higherlevel of understanding of the concepts on Bloom’s Taxonomy and to develop effective problem
projects. For a largerproject, one semester may include research into the problem, design of a solution, validation of thedesign using appropriate software tools or calculations, and a report to the industry partnerdetailing the proposed design. Another semester may include fabrication of a working prototype,validation of the prototype, and a presentation of the final design and prototype to the industrysponsor. Each student is assessed using monthly progress reports and the team is assessed using acomprehensive report each semester, poster, and oral presentations. Examples of past ISPs includea fluid-powered gantry crane [1] and a decoupler for driveline dynamics [2].For the SAE CDS competition track, LTU students compete in Baja SAE, Formula SAE

Results from preliminary evaluations ofthose Bloom’s taxonomy graduated questions, along with the implications and limitations of theseresults are provided.1. Introduction “Tell me, and I forget.

Recommendations are also provided.IntroductionThere are many advantages to hands-on experiments which are particularly beneficial forstudents who are visual and kinesthetic learners. With limited budgets, the challenge is to designsuitable lab experiments which are not too costly, particularly when multiple setups are requiredfor larger classes. Penney and Clausen [1] have recently written a very helpful book that providesmany relatively inexpensive fluid mechanics and heat transfer experiments. The experimentreported here is an adaptation of a sharp-edged orifice demonstration in the book, which wasoriginally described by Penney et al. [2
America’s Promise (LEAP) was able to identify many suchHIPs that are gaining attention [1]. In a subsequent report, Kuh found that students whoparticipated in these HIPs show that they were positively affected by these activities, asmeasured by the National Survey of Student Engagement (NSSE). It was found that these“deep approaches to learning are important because students who use these approaches tend toearn higher grades and retain, integrate, and transfer information at higher rates [2].” Thus,what we set out to do is to apply HIPs to a 300- level engineering course at a state collegelevel and gather data regarding its effectiveness, student reflections, and possible futureimprovements for better learning outcomes.HIPs in a Mechanical
