As we train students to become scientistsand engineers, it is important to also provide training in the scientific method, and a recognitionthat a reliance on empirically demonstrable, replicable results is essential to what we do. This isessential for individuals responsible for designing the cars, airplanes, cellular devices, and energysystems of the future, because these devices must function properly in the physical world. A fullhistory of the scientific method, and its role in the natural sciences is provided in [1]. Other sup-port for using experimentation as a tool for building student knowledge stems from John Dewey[2], as well as the
, the structure of this approach is readilyapplicable to a wide range of engineering disciplinaries with laboratory courses. 1Introduction Each year the National Association of Colleges and Employers (NACE) releases its surveydata on the proficiency of various skill sets of new college graduates compared to employer’sexpectations. Communication skills are consistently among the top competency gaps between thecareer readiness of recent college graduates and employer-rated importance across all disciplines,including engineering [1]. Many studies in the literature [2,3] also pointed out that effectivecommunicative skills, and more specifically, technical writing skills are vitally important

The lab meets the following learning goals; 1) develop proficiency in using a desktop3D printer, 2) explain the impact of selected 3D print settings on dimensional accuracy andtensile strength of a shape, 3) evaluate the use of simulations in the engineering design process,and 4) use data to improve the design. The entire class of junior mechanical engineeringstudents, approximately 80 students annually, are split into teams of four to five students perteam. Collectively, the class investigates the impact of infill density (20, 40, 60, 80, 100 %) andthree print orientations on the dimensional accuracy and strength of a printed part under tensileload. Each team uses the data in conjunction with static, structural simulations to redesign

Since these high-profile incidents, academic lab safety, specificallychemical lab safety, has spurred a number of publications, programs, and risk managementguidelines and policies on academic lab safety and promoting

They are also examples of both active learning and collaborative learning[2] , which have been shown to increase student learning and conceptual understanding of basicconcepts (as reviewed in [2] ). Therefore, they are an important and necessary component of anyhigh-quality engineering education program.In traditional in-person engineering education, projects and labs typically utilize existinglaboratory equipment and manufacturing capabilities of the school. In recent years, however,there seems to be a growing demand to make these interactive projects and laboratories availablefor remote participants, either as a part of an online

The selected articles were read and coded based on the KIPPAS (Knowledge andUnderstanding, Inquiry Skills, Practical Skills, Perception, Analytical Skills, Social andScientific Communication) framework. The findings from this review suggest there is a need formore research into students' practical, inquiry, and analytical learning outcomes. This study alsoidentifies current practices and identifies gaps in the existing literature. The implication of thefindings for further research and practice were also discussed.Introduction Laboratory education is an important feature of the science curriculum at all levels ofeducation [1]. Experiments are essential to science learning because they are the avenue throughwhich students
quantities ofcomplex-shaped parts with consistent quality.The purpose of this project is to introduce students to thermoforming and drape forming. Drapeforming is a simplified version of vacuum forming where a sheet of plastic is heated to asufficiently high temperature so that it can be formed around an object. The plastic sheet can beheated in an oven and stretched over the pattern using suction or vacuum. Thin-gaugethermoforming is used to manufacture parts such as containers, cups, lids and trays while thick-gauge thermoforming is used to make plastic pallets, vehicle door and dash panels, and utilityvehicle beds. Figure 1 shows the principle of thermoforming as described by Groover [1] . Thefundamentals of plastics thermoforming and tool design
, 2023Prioritizing learning outcomes for chemical engineering laboratory coursesAbstractChemical engineering laboratory courses allow students to work hands-on with equipment theymay see in industrial positions. These courses often account for learning outcomes related toexperimentation, teamwork, and communication skills, among others. To work towardsalignment of laboratory courses with industrial needs, it is necessary to understand 1) thelearning outcomes currently addressed in laboratory courses and 2) how key stakeholdersperceive the importance of specific laboratory learning outcomes. Therefore, three surveys weredesigned based on thirteen proposed learning outcomes for engineering laboratory courses thatwere identified in the literature [1]. The
cost and timeconstraints of laboratory courses, many faculty members have moved to a mobile studiopedagogy where the students are equipped with relatively low-cost laboratory equipment thatallows them to perform experiments and measurements outside the laboratory. This approach hasbeen implemented in a variety of individual courses, including introductory first-year courses[1], electronics [2], digital design [3], and communication systems [4], [5], [6]. Some authorshave reported on the use of mobile studio pedagogy in multiple courses [7], [8], and someschools have implemented the technique throughout the electrical engineering curriculum [9],[10], [11]. A helpful discussion of the advantages and disadvantages of various logistic options

This helps studentssee right away if they're doing things right or wrong so they can fix mistakes as they go.In the early 1900s, a researcher named Jean Piaget found that kids understand things better whenthey do hands-on activities instead of just hearing facts [1]. And other experts like Meyers andJones agree that learning is more effective when students are actively involved, like reading,writing, talking, solving problems, or answering questions in a thoughtful way [2].Also, many studies have shown that technology and hands-on activities can help studentsunderstand how theory connects to real-life situations in engineering projects. This kind oflearning, called experimental-centric-based instructional
also included sensors, actuators, resistors, LEDs, a breadboard, andjumper wires to connect components together [2]. Once supply chain issues were resolved amore elaborate IoT learning toolkit was developed based on an IoT learning platform, theKeysight U3810A [7]. This learning platform includes an integrated basic processor board, theBeagleBone Green, along with a variety of sensors and components mounted onto a larger circuitboard. The U3810A IoT learning platform is pictured in Figure 1. In addition to the U3810Aand its integrated basic processor board, the advanced learning toolkit includes jumper wires tomake connections among its components. A breadboard is also included to enable students toincorporate additional sensors, actuators

strategies to teamformation in capstone courses, highlighting the tradeoffs between student led and instructordesigned solutions [20]. Early on, it became evident that providing clear and consistentcommunication regarding roles and responsibilities was essential to ensuring students’ positiveexperience with the course. To address this, the course faculty introduced several interventionsinto the structure of the course to help improve team dynamics such as communication and workdelineation. A more thorough explanation of the design of this structure can be found in [1].These elements are intended, like scaffolding, to reside adjacent to the coursework but to supportstudents in understanding and navigating challenges should they arise [2,22,23

There has been an ongoing effort to regulate drone noise emissionsin urban and residential environments [2] – [4], where drones are becoming integral to tasksranging from videography to package delivery. The primary source of propeller noise comesfrom the vortex drag inherent to the traditional propeller design [5]. This technological issueprovides a practical challenge that engineering students can tackle during their studies. Studentsare prompted to explore the mechanism of vortex formation and alternative designs that mitigatethis issue

In both cases the idea is toprovide the students with flexibility to choose topics and types of work they want to doindependently at their own pace and learn independently either by a single student or students ina group [1]. It allows students to learn about a subject that is unavailable in traditional curriculaor about a topic students would like to explore in greater depth. Faculty and students

This chapter explores concepts like shear stress, shear strain, rigiditymodulus, and the mechanical response of materials under torsional loading. To enhanceunderstanding, a 3D-printed model of a torsion tester was made (Figure. 1). This modelshowcased the sample grips, drive motor assembly, and data acquisition unit. The 3D model waspassed around during the class for the students to touch and feel.Fig. 1. 3D printed mock-up of a torsion testerIn addition to this another device, the torque demonstrator was also developed.

This WIP reflects a commitmentto advancing engineering education in response to the evolving demands of the profession.IntroductionExperimental curriculum in engineering has witnessed a decreasing involvement. Laboratorycourses are simply used to support and demonstrate theoretical aspects of core engineering classes[1]. Traditionally laboratory experiments involve a step-by-step procedure with a known outcome.However, this method has proven to be effective in demonstrating a concept, it limits the student’sengagement in learning and doesn’t enhance their problem-solving skills or creativity

Finally, by providing evidence of thismodule’s implementation in two distinct engineering laboratory courses that vary in class size,topic, scope, and organization, we aim to provide suggestions and encouragement for translationof this module to laboratory and design courses in a variety of STEM disciplines.IntroductionExperimental laboratory courses are foundational to undergraduate instruction and experientiallearning in various engineering disciplines [1], [2].

In the second phase of the project, a few of these ideas wereimplemented in the course and feedback was solicited from current students. This paper willdiscuss the brainstorming process and outcomes, changes made to the course and space, as wellas some preliminary feedback.Diversity, Equity, Inclusion, Belonging, and Access in Undergraduate Laboratory CoursesDiversity, equity, inclusion, belonging, and access (DEIBA) is an initiative that emphasizes thesignificance of constructing environments where individuals feel welcomed, respected, andpresented with equal opportunities to succeed [1]. Lab environments have often lacked DEIBA,resulting in potential or inadvertent
abilityto enable experimentation from any location with an internet connection, thus eliminatinggeographical constraints and offering scheduling flexibility [1–5]. They also alleviate financialburdens associated with setting up and maintaining physical lab infrastructure. Furthermore,remote labs contribute to equitable access, expanding opportunities for students fromlower-income and underrepresented minority backgrounds, especially through communitycolleges [6, 7].However, while remote labs offer these benefits, they also present challenges, as they necessitateaccess to stable internet connections, modern devices, and proficiency in using online platforms,potentially widening the technological barrier for certain groups and triggering digital

Thispedagogical approach aims to foster self-efficacy, critical thinking, and problem-solving skillsamong students and enhance their interest and motivation in STEM fields [1], [2]. However,assessing the effectiveness and impact of this pedagogy poses significant challenges, especiallyin measuring student engagement during the implementation of
digitalinequalities that could prevent some students from receiving a high-quality education. The loss ofaccess to campus Wi-Fi and university devices has posed a challenge for some students,particularly those from lower-income families, who struggle with consistent internet connectivityand updating/maintaining their technological devices. This research is a continuation of aprevious study [1] that analyzed the student perspective on remote hardware and equity inelectrical and computer engineering education in the post-pandemic era. That previous study,which was based on a limited sample of students, revealed intriguing trends in students’perceptions of equity, which prompted us to conduct a more extensive survey, the focus of thispaper.According to Katz’s

Moreover, Indiana State University (ISU), where the lead author is currentlyteaching, allows instructors to include their own questions in anonymous evaluations. The leadauthor added two questions related to laboratories. The questions were student rated andappeared in the ISU questionnaires as: 1) Laboratory experiments help to understand theoreticalconcepts and 2) Laboratory experiments are interesting. This paper presents the ISU studentratings on these questions for various courses and also compares their ratings of questions withthe overall student ratings for each specific course.The findings of this paper shows how students perceive the laboratory
the importance of epistemology as is seen in the 2006document produced by a group of leading educators titled The Research Agenda for the NewDiscipline of Engineering Education where “engineering epistemologies” is one of five researchdirections listed [1]. That document defines epistemology as “research on what constitutesengineering thinking and knowledge within social contexts now and into the future” [1, p. 259].While there is no precise agreement in engineering education literature about what constitutesepistemology as Beddoes found by reviewing literature since the 2006 agenda [2], the concept ofepistemology as a viewpoint toward the nature of engineering knowledge will act as a definitionfor the current work.

©American Society for Engineering Education, 2024 The Implementation and Assessment of the Effectiveness of Peer Teaching Instructional Technique in Lecture and Laboratory CoursesIntroductionPeer teaching is based on Bandura’s social learning theory, Piaget’s cognitive development, andVygotsky’s social constructivist learning theory [1-2], in which knowledge is sociallyconstructed by consensus among peers. The basic principle of peer teaching is that teachingsomething to others is an effective way to learn it [2-3]. Peer teaching involves students acting asboth teachers and learners, assisting each other in gaining knowledge and understanding throughinterdependence [4]. By teaching others, students
