In addition, the course would introduce students to each of the College’s tenacademic programs, campus resources, advising, and provide opportunities for cohort-buildingduring a semester when most general education courses occur in other colleges. In Spring 2020,feedback was gathered via department-led discussions and a multi-disciplinary working groupwas formed to develop the course learning objectives and assessment strategies forimplementation in Fall 2020.Course Structure: Learning outcomes focused on the Design-Thinking process, effective andinclusive teamwork, technical communication, self-reflection

Students may not reflect on the entire course when doing the evaluation. Additionally, the evaluation is usually given at a stressful time in the semester.Just-in-Time TeachingJust-in-Time Teaching (JiTT) [1], is a technique where instructors use student responses to pre-lecture activities to tailor the upcoming lecture sessions to meet the needs of the students.Typical pre-lecture

The course proves to be successful in a sense that students participate seriouslyas reflected by the many interactions with the faculty and teaching assistants. Most queries are about howto make the roly-polies, how to do the measurement, how to work out the theoretical prediction, and whethertheir measurement matches with the theory. Students show good understanding of the principle of virtualwork. This project-based method is a viable way to teach virtual work in conventional Static courses. It is worthwhile to mention that the prototype fabrication and force measurement are performed at home,which is particularly appealing during the

These positive experiences in the laboratory have thepotential to significantly impact students’ interest in pursuing STEM careers when they get older[20].E. Theoretical PerspectiveStudents benefit from an instructional approach grounded in the experientialism learning theory.A hands-on experience in the mobile STEM lab provides students with an active way toexperience science, technology, engineering, and mathematics (STEM).

The class has large enrollments of 100 to 120 students persection and an annual enrollment of 400 students.

However,these projects accounted for 60% of students’ final grade; therefore, course grades suggest thatthe developed food-themed projects helped students continue to perform individually andwithout in-person support structures at levels similar to students who work on projects in teamswith in-person support structures. Student perception was compared between the courses with team-based model projects andindividual-based physical-model projects. Here, Likert-scale anonymous course evaluations (1-strongly disagree, 2 - disagree, 3 - neutral, 4 - agree, and 5 - strongly agree) were compared forinstructor-taught courses with team projects (Fall 2018 and Fall 2019 semester) and

Dataobtained through this process will likely provide information about why team members join aparticular team, how members perceive that their experiences on the team are impacted bygender and the gender composition of the team, and about individuals’ perceived levels of self-efficacy. The information will be used to identify psychosocial or other factors that maycontribute to self-efficacy. Common themes from the interviews and focus groups will be

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
