The damped sinusoidal output of each uncoupledcircuit was recorded and curve fitting was performed to obtain values for the

Teaching Using Virtualized IoT DevicesAbstractKinesthetic Learning Activities (KLAs) are immensely valuable in courses relating to Internet ofThings (IoT) development. KLAs enhance understanding of software, hardware, and theirintegration through hands-on experimentation in a physical lab/classroom. However, the shiftfrom in-person to online classrooms, over the past year, has raised concerns about the viability ofKLA based teaching. In this paper, we recount lessons-learned, challenges, and opportunities inmoving from physical to virtual IoT labs. This is based on our experiences of conducting threeonline programs: two workshops on Pseudo-blockchains with Virtual Raspberry Pis and agraduate course in WSN

an upper-level engineering laboratory is to teach the connection between rational andempirical design and technical writing. Technical writing cannot be taught in isolation fromtechnical context 11 . It is important for an upper-level engineering class to emulate engineeringdesign as much as possible. The combination of rational and empirical design and technicalwriting fits into the general approach of problem-based and project-based learning, (PBL andPjBL, respectively). The difference between PBL and PjBL is that in PBL the instructor specifiestasks to be performed in basic steps. In contrast, PjBL specifies a greater task and the studentscreate strategies and approaches 12 . Both PBL and PjBL have shown to be effective in highereducation

IntroductionEquity suggests that all children receive the same privileges and experiences, regardless of theirzip code. Equity in STEM (Science, Technology, Engineering and Math) education is front andcenter in education today [1]. The 21st Century has birthed a technological age like nothing everseen before. Likewise, careers in STEM continue to grow around the globe and today’s globalpopulation is

Room IS 105Worcester Polytechnic InstituteTeaching laboratories is an essential component of chemical engineering education. They are designed to help students think criticallyabout chemical engineering principles and practices by planning and execution of experimental work followed by reflection, analysis, andinterpretation of data. However, operating teaching laboratories with social distancing measures poses significant logistical and safetychallenges, and alternative modes of delivery could be a realistic way forward in adapting engineering curricula to the post COVID-19world. This paper is aimed at identifying common approaches and strategies implemented in transforming hands-on labs into hybrid, virtualor remote operation to achieve

The virtual room audio was connected to the classroom audio system sothat the distance learning students could hear their in-person peers speak during the class andvice versa. In addition to the classroom audio-visual technology, the real-time chat functionalityof the virtual room was used to interact with the distance learning students in a more efficientway. An experienced graduate teaching assistant (GTA) moderated the chat throughout the classand answered most of the questions from the distance learning students. If any question or issueraised in the chatbox needed the instructor’s

recording system presented here could be used to demonstrate these concepts, for example by adding inductors and RLC circuits and filters. However, a large inductance may be required to observe resonance and underdamping effects due to the slow voltage sampling rate. • Students do not learn to operate commercial electronics lab equipment, such as oscilloscopes and power supplies, as these are not used in this course. Often the next instrumentation course students take is a laboratory or design course that expects students to be familiar with commercial lab equipment usage, so a tutorial may be necessary to teach these skills. • Currently, course lab materials (beyond the Arduino kit) cost

To reinforce this multidisciplinary knowledge, a series ofteam-based challenge exercises were recently incorporated into a Biomechatronics course at theRochester Institute of Technology (RIT) using the low-cost Robotis Mini Humanoid robot and aproject-based learning approach. Students were required to complete task-based challengesusing both the Robotis virtual platform and the physical humanoid robots. The virtualenvironment allowed students to do the majority of programming outside of the laboratory,thereby minimizing the amount of time required with the actual robots. As part of the challengeexercises
