Along with the GUI interface, the input parameter selection and output informationcomputed for the first order system are shown. The input parameters can be selected either withmanual entry for specific values or using slider bars for varying the resistance and capacitancevalues. The output of the time constant and settling time are updated as the user selects variousvalues for the RC circuit. Page 11.479.3Figure 1 – MATLAB 1st Order System Characterization – Time Response

He also discussed how the units cancellation process can provide a checkof the validity of equations, both in choice of governing equations and whether any algebraicmanipulations were done properly. His study suggested that students accept governing equationswithout much thought about the need for dimensional homogeneity, supporting the finding bycognitive scientists that “humans tend to discriminate only as finely as necessary.” He discussedthe inclination of students to interpret constants in relationships as

Through meta-analysis of outcome research in undergraduate STEMeducation, Springer, et.al.1 show that various forms of small group learning are effective inpromoting greater academic achievement and increased persistence through STEM courses andprograms. The group studying environment offers students the opportunity to engage in a morein-depth discussion with peers, sharing information and knowledge about a course they are 1collectively enrolled in

. 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
using collaborative quizzes. However, they did findthat collaborative quizzes encouraged students to come to class prepared and students who tookcollaborative quizzes viewed the quizzes more favorably. Enz and Frosch come to a similarconclusion stating “Peer collaboration improves quiz scores, is favorably perceived by studentsand enhances their course satisfaction, but does not improve subsequent performance on midtermand final examinations taken noncollaboratively.”13 However, Roa, Collins, and DiCarlo find“completing the quizzes in groups enhances the understanding of the material.”14 Moreover,Leight et al. hypothesis that collaborative testing might improve students’ obtainment of lower-order learning outcomes (Bloom’s levels 1 and 2), but

Other engineering studentscan take the course as an elective; prerequisites include statics and calculus. The traditionalcourse used the three 50-minute weekly class meetings for lecture. The blended course used thesame class meetings for a mixture of lecture, in-class activities, and problem solving (Table 1).The two non-lecture days were held in a classroom specifically designed to facilitate group workand active learning. The two classes used the same online homework and exam formats.Table 1: Weekly course structures for Traditional and Blended courses in this study Before class Monday
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.

Economic and technological solutions, political regulations or financial incentives are not enough. We need a fundamental change in the way we think and act.” Irina Bokova, Director - General of UNESCO [1]Sustainability awareness and action are of growing importance for the care and protection ofpeople, societies and cultures; profit, economic feasibility and responsibility; and for theenvironment and life preservation. Engineers have profound impacts on sustainability and itsdevelopment or lack thereof. And thus, it is

Student feedback and their measuredperformances on each technical writing assignment is presented herein.I. IntroductionAs the Covid-19 pandemic abruptly ended in-person classes, the transition to teaching fullyonline offered both new possibilities and challenges. On one hand, interactive software such asZoom allowed for unique and dynamic lectures which could be recorded and later reviewed bystudents. On the other hand, engaging collaborative projects such as designing and fabricating anelectric ceiling hoist [1] are no longer possible. At Chico State, Mechanical Engineering Design,or MECH 340, is a

Due to the limited time for covering GD&T, weproposed an approach for teaching GD&T fundamentals in an existing course, in which we willfocus on dimension tolerances and types of fits. Because of the complexity of geometrictolerance, we will only explain basic definitions of geometric tolerances and then explainGD&T’s Rule 1, which describes the relationship between dimension tolerances and geometrictolerancing. We chose the course MECH3000-Design of Machine Elements to implement thisapproach because students can directly utilize GD&T fundamentals in their design projects. Theobjectives or the key topics of teaching the GD&T fundamentals in this approach are:• Have a basic understanding of the
Society for Engineering Education, 2021 The Development and Use of Moderated Engineering Teaming Exercises (METE)IntroductionThe purpose of this paper is to define a framework to allow an instructor to effectively teachteaming practices that are consistent with the ABET requirements for teaming. The teamingpractices are developed through the implementation of Mechanical Engineering TeamingExercises (METE) in upper division engineering classes.ABET-EAC accreditation requirements [1] include the following as the fifth of their sevenstudent outcomes:[Students will demonstrate] an ability to function effectively on a team whose members togetherprovide leadership, create a collaborative and inclusive environment
the region of fluid near a surface where a velocity gradient naturallyexists due to the viscosity of the fluid [4]. Due to no-slip boundary condition, the velocity of thefluid that is adjacent to the surface of the body is zero. The velocity of the fluid eventuallyreaches the free stream velocity as the vertical distance increases (Fig. 1). The vertical distancefrom the surface to the point where the local velocity is 99% of the free stream velocity isdefined as the boundary layer thickness [4]. Figure 1: Boundary layer thickness illustrationFor the flow over an airfoil, due to its curvature, the incoming fluid will reach a maximumvelocity, and up until this point it witnesses a favorable pressure gradient (high to
(Lappalainen, 2009). To improve teaching and learning of professionalskills in engineering students, several methods have been investigated, including 1) collaborativelearning, 2) interprofessional learning, and 3) service learning. Collaborative learning has beenimplemented to increase learning of concepts as well as higher order thinking (Menske and Chi,2019). Interprofessional learning experiences, which involve students in more than onediscipline, can expose students to communication with a range of audiences, however there arelogistical challenges within interprofessional learning and students may not value theprofessional skills as deeply as the technical skills (Carrico et al., 2020). Finally, service both inthe classroom and at the

We wanted tounderstand how our students were responding to the added stress of suddenly and drasticallychanging their learning environment and the ways that affected their learning – especially inrelation to mental health.The college mental health crisis has been ongoing in America since the mid-1990s [2]. In 2010,45.6% of students reported feeling hopeless and 30.7% of students reported depressioninterfering with their daily lives. Mental health disorders have been linked to decreased academicperformance, increased risk of drop-out, and decreased functioning after graduation – which arenow
today’s global economy, engineering graduates need to be prepared to possess both a strongtechnical skill set and an entrepreneurial mindset (EM) to drive innovations. According toKriewall and Mekemson [1], “an entrepreneurial minded engineer (i.e., an engineer instilled withthe entrepreneurial mindset) places product benefits before design features and leveragestechnology to fill unmet customer needs”. So, an engineer that is entrepreneurially minded canfocus on unmet customer needs and consider the benefits and impact of their designs in additionto their technical details. Many engineering programs and educators have now recognized theimportance of instilling an entrepreneurial mindset and many efforts have been made to improveprograms and
finding,demonstrating, or building fluid mechanical systems in everyday life. We employ two differentinstruments to track students’ experiences in this course. First, we compare students'performance in a fluid mechanics concept inventory assessment that they take at the end of eachsemester. In addition, we also adopt a set of items from the Motivated Strategies for LearningQuestionnaire (MSLQ) to measure the impacts of these changes on students' motivations andattitudes. We reflect on the implications of this transition process and provide an outline of thefuture developments of this work.1.

motivation and self-assessed learning are discussed.Introduction The importance of hands-on experiences in engineering education has been recognized fordecades [1], yet creating and running an effective hands-on experience, especially in the thermalsciences, is challenging. Several design-build-test projects involving heat exchangers as part of amechanical engineering curriculum have been made [2-5]. Sherwin and Mavromihales reporteda project for students who built cross-flow air-water heat exchangers out of metals tubes that wascarried out for several years [2]. Forsberg presented a capstone design and construction projectinvolving a water-water heat exchanger demonstrator with three modules for double-pipe, cross-flow, and shell and tube

Marquez and Garcia reported that the physical understanding of fundamental concepts inEngineering Mechanics were strengthened by the integration of visual tools during lecturesessions, and aided their understanding of real-world applications [17].With the outbreak of the COVID-19 pandemic, the routinized and normalization of the educationalprocess was thrown into a tailspin that forced both educators and students to adapt to a profoundlydifferent learning environment. This new, complex environment presented educators bothchallenges and opportunities to reimagine, reassess, and reorganize course structure, contentdelivery, and assessments in a complete virtual setting

Due to the widening of the horizon of the uses of 3D printing,machine learning (ML)-based technologies have been used to improve 3D printing processes. 3Dprinting technologies have been widely applied in many fields, including aerospace, medicine,industry, and beautification. Also, additive manufacturing has been used in biologicaltechnologies, known as 3D bioprinting, which will be widely used for medical or daily purposes[1],[2].In-situ defect detection is
