. After alsocomparing the results for support B, students are asked to write a summary of what they haveobserved about the behavior of the loading as their first exposure to superposition. Figures 3 and4 are reintroduced in a later class when superposition is formally introduced.The final two loadings demonstrate distributed loads and resultants. Figure 5 represents a five-inch-long, uniformly-distributed load of 2 grams per inch spaced evenly beginning at ½ inch frompoint A and ending at 5 ½” from point A. Students must reflect on the possible support reactionsif they summed the reactions for each individual 2-gram load. They must also indicate what thetotal load is on the beam (10 grams) and identify where the center of mass occurs for this

choicelearning assessments in both courses to participate in a think-aloud study. We incentivized theirparticipation with a small financial reward. We combined selected questions from the twolearning assessments so as to (a) develop a combined assessment that can be finished in athink-aloud interview within an hour and (b) have all the key topical areas in each coursecovered in the new subset. The original fluid mechanics and mechanics of material assessmentsin 2019 had 36 and 20 problems, respectively. In 2020 we combined 11 of the fluids with 19 ofthe solids problems into one assessment for the think-aloud studies. Two researchers in our team each conducted four interviews for a total of eight. To definea measure of how our participants

After the interview, a third party transcribed the interview, removed anyidentifiers in the transcript, and destroyed the video recording files.ResultsFifty undergraduate engineering students were surveyed in the study. Descriptive statistics of theparticipating students are presented in Table 1. While students were given nonbinary choices whenasked for their gender identity, very few identified outside of the male and female categories,and so results given here are for those two groups (referred to as men and women, respectively,here).The majority of men and women sampled entered college with no
cleartrends for the study.MethodsDuring the academic year, students were assigned various tasks to complete per week (AppendixA1 and 2). Group “A”, comprised of 9 students, worked on a project to build a moving devicewhich would be tested for dynamic performance, while Group “B”, comprised of 7 students,worked on building a structure to be tested for load-bearing performance.Students reported their previous week’s results using an individual-based Project Status Report(PSR), in which they also enter the time spent on all of the previous week’s tasks. The number oftasks to perform and points to be earned varied by week, and therefore a weekly percentile scorewas determined to be compared against the reported work time for that week.At the end of each
was initiated to determine (a) existing levels of knowledge among the students, and(b) efficacy of brief, course-relevant lessons at increasing student awareness of the intersectionbetween course topics and social/environmental justice. To assess awareness across the range ofthe students in the department, surveys were conducted in the Introduction to EnvironmentalEngineering and Introduction to Civil Engineering classes, as well as the EnvironmentalEngineering Senior Capstone class. Students were asked to complete an anonymous surveyassessing knowledge and awareness of social and environmental justice issues before and after asocial/environmental justice lesson was delivered to the class.The following research provided a preliminary step

. During the final week of the Fall 2020 semester, an 18-question survey was sent out toeach student of every lab section. In total, 152 students participated in answering questions fromthree categories: individual demographics, course organization/delivery and student engagementstrategies. The various questions asked for demographics can be seen in Figure 1. As can be seen in Figure 1 (a) and (b), all of the students are undergraduates with 82% ofthe students falling into the upper-division category and nearly all the students are taking the coursedue to major degree requirement. Another interesting point is revealed in Figure 1 (c) where over72% of the students had taken less than two online courses prior to the virtual Fall 2020

The CRS consists of transmitters (nicknamed clickers) and a base. A clicker oftenhas five buttons labeled as A, B, C, D, and E.During a lecture, each student pushes a button (A, B, C, D, or E) on their clicker to respond tomultiple-choice questions the instructor poses and displays on a projector screen in theclassroom. The collective response from all students is immediately displayed on the projectorscreen.

For example, several papers suggest immersive technologies to enhance specificlearning outcomes in engineering by enabling remote/online teaching and providing a flexibleand safe virtual environment [3]. Furthermore, immersive technologies can facilitate teachingand learning of design concepts (e.g., 3-dimensional design for a new product) while enhancingstudents’ interactions, creativity, and spatial skills [3].(a) Discipline breakdown for PBL.

and the highly competitive nature of the application process we have attempted tocreate opportunities at the college as well. Mentors work with students to help shape andidentify project goals and to offer guidance and support in the students’ execution of the project.While not a requirement by any means, students are encouraged to choose projects that aremeaningful to them and that serve a purpose in their communities. It is probably not surprisingthen that projects have often involved utilizing renewable energy like the solar boat projects,building autonomous robots meant to disinfect a room, and utilizing sensors to gauge airpollution (Figure 1).

ladder. Question 1 asks the user to find the coordinates of twopoints A and B, which are the end points of a ladder against a building. When that question isanswered correctly, then solving for the distance between those two points (Question 2), asshown in Figure 4 (b), would be asked as to calculate the length of the ladder. Question 3, asshown in Figure 4(c), asks the inclination/slope of the ladder the worker must climb. If all thethree questions are answered then the student would be able to see an animation of the workerclimbing the ladder. However, if any of the three questions are incorrect or unanswered, then theworker will not climb the ladder, that means the player did not score all three points. a. Part 1 – Question 1
thestudents thought simulation laboratory exercises were excellent or very good.We also compared the percentage of students who performed at the A, A-, B+, B, and B- levelswith past records (while teaching was in-person), which turned out to be comparable and similar.This indicates the effectiveness of these simulation-based labs & projects, and their contributionin helping to maintain the course standard.IntroductionIn many institutions, undergraduate courses in Feedback and Control for engineering students areusually at the junior level.
