hourLearning Outcome AssessmentThe assessment methods for this comprehensive bridge project encompasses two primaryassessment methods: performance-based assessment and technical writing. The assessmentframework is structured to ensure a multifaceted analysis of each team's output, focusing on bothquantitative and qualitative metrics.The performance of the student-designed bridges is appraised according to two main criteria:data comparison, which accounts for 70% of the overall assessment, and peer reviews, whichcontribute the remaining 30%. The quantitative assessment hinges on the comparison of themaximum force sustained by structural members in both the original and the redesigned bridges.This comparison is determined by Equation (1), which
various stages intheir career; one participant recently retired, three were senior level managers and two wereprocess engineers. These industry representatives work in sectors ranging from energy (WBIEnergy) including oil and gas (Cenex, Conoco Phillips) to semiconductors (Micron) andmaterials science (3M Corp.).The survey focused on genre, technical communication skills in general, oral communicationskills, and written communication skills. It asked how often the survey taker used differentwritten and oral communication genres on a Likert scale with 1 corresponding to never, 2-yearly,3-monthly, 4-weekly and 5-daily. The survey also asked what technical communication skillsthey felt were most important on a Likert scale from 1 to 5 with 1 being
from“strongly agree” to “strongly disagree.” The two free response questions are (1) “Have you everhad any concerns about the peer review process? What are they?” (2) “Do you have anycomments/suggestions on how technical writing is taught in this course, or Engineering Physicscurriculum, or in your college courses in general?” With the approval from Institutional ReviewBoard at my university, direct and indirect assessment data were collected with the informedconsent of students enrolled in the course.Results and Discussion Data of direct assessment based on the rubric in Appendix B were collected for threesemesters of running EP3910 for a total of 15 students who took the course. The average pointgrades are divided by the maximum
In Progress: Lab on Cart: Developing a Low-Cost Fluid Visualization Setup for Experiential Learning, Class Demonstration and OutreachAbstractDespite being present in many natural phenomena and engineering systems, fluid dynamics isoften perceived as difficult and mysterious by students. The transparency of common fluids (airand water) and the complex, non-linearity of the governing equations make understanding thesedynamics challenging.Flow visualization has been shown to be an effective method for teaching complex fluid dynamicsto a general audience. The streamlines over a car prototype in a wind tunnel, or the vortexformation of a hurricane, to name a couple, have become household images confirming the efficacyof this technique

In total, counting all of the semesters and lab sections that you have taught since Spring 2022, how many teams of students have you overseen in this role? (As a reminder, each lab session consists of up to two teams of students.) 2. Approximately what percentage of the teams that you observed were able to design a fountain system that met all stated performance objectives on the first try? 3. What percentage of the teams whose fountains succeeded on the first try do you feel merely got lucky, rather than as a result of rigorous testing and design? 4. In the weeks leading up to the final

Student comments indicate the confusion: “I find it extremely difficult” “seem like jumps in reasoning” “Theres too much reading in between the lines to understand the theory” “order of magnitude analysis and general approximations content ... it’s hard to see ‘how’ to do stuff, I just watch the lecturers ‘do’ stuff.” Education challenge §2: physical observations that boundary layers are thin Visually illustrate by experiment that boundary layers are thin, relative to the length over which they develop (δ ≪ L), for high Reynolds numbers.Approximation, based on the assumption of a thin boundary layer, leads to a solution givenqualitatively by Prandtl [1] and then
headphone with abuilt-in microphone. The advantages of this concept are the fast and cheap setup as noautomation is required. Most universities should be able to implement such a concept fairlyquickly. However, an instructor must be present during each experiment of each group. This inturn enables to students to ask direct questions during the experimental session, which is notpossible using remote laboratories due to the lack of supervisions.Figure 1 compares the three laboratory types employed in this course. The comparison furtherincludes the ultra-concurrent laboratories and virtual laboratories, which are also being developedfor this course but were not part of the comparative analysis in this work, given they had not beenused in the three
difficult lab course. The biomedical instrumentation lab course isrequired for all undergraduate bioengineering majors and is a technical elective for several otherengineering majors at a large public land grant university in the Midwest United States. Thecourse content has been challenging for many students. Additionally, some students noted otherchallenges in the lab, e.g., reading labels on parts, lights, and lab bench layout. The goal of thisproject is to reduce these challenges with the content, space, and supplies.In the first phase of the project, the research team used methods from Universal Design forLearning (UDL), human centered design, and entrepreneurial minded learning to evaluate thelaboratory space and course materials and generate

In 2021, the laboratory activitywas redefined to include gamification concepts such as time constraints, scores, and multiplemodes, among others.The results in terms of motivation and level of completion have been positive. During the lasttwo semesters, all of the students have completed the implementation of the game with its basicfeatures (time and score), more than half of the students have implemented the high scoresfeature, and a small percentage have implemented multiple game difficulty levels.We have found that these types of transformations of academic activities are important becausethey provide an alignment between the curriculum and the motivators of this generation ofstudents.

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.

learning.IntroductionCommercial drones have become prominent in various industries during the last decade [1].Growing alongside this trend is the increasing concern for the noise generated by the propellersof these quadcopter drones. 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
1: Model Development and Validation:This phase is aimed at developing and validating a deep learning model capable of automaticallyidentifying and documenting at least 26 distinct activity constructs in experiment-centric STEMclassrooms. These constructs are derived from existing observation protocols, such as COPUS,but are extended and refined to capture the nuances and dynamics of the experiment-centricpedagogy. The model will leverage state-of-the-art AI technologies, such as convolutional neuralnetworks (CNNs), object detection models, generative adversarial networks (GANs), andtransformer models, to analyze the audio-visual data from the classroom and generate detailedreports on classroom activity and student engagement. The model will
