reflections on the guest speakers account for approximately 30% ofthe grade. Reviews of the lectures from the fall 2019 course suggested that students wanted to see moreof the “day in the life of a chemical engineer.” In the fall of 2020, alumni presentations from avariety of industries were added to the lecture schedule. Alumni talked about their job andindustry, the career path, provided advice on life during college and after the degree. This changewas easy to implement because the lectures were operating in a virtual format due to COVID-19restrictions on the number of in-person students allowed. While the students really respondedpositively to the addition of alumni speakers, even in a virtual format, reviews asked for abalance between alumni

correlation (ICC) is used to measure inter-rater reliability for more than tworaters. ICC may be conceptualized as the ratio of between-groups variance to total variance.The inter-rater reliability for Question 1 among the three raters is reported in Table 4.Levels of inter-rater reliability range between 0 and 1.0. Reliability estimates in the range of0.70 are considered acceptable, and the levels for Question 1 on the Ion Exchange Laboratoryand Virtual Laboratory are within the acceptable range. The low level of correlation among theraters on the Heat Exchange Laboratory experience is somewhat problematic. It is not clear theextent to which the differences among the raters reflect variability in the student responses. It isbelieved these ratings

approximately 50% of BioChEstudents work in the biotechnology and pharmaceutical industries.Figure 1 – Initial job placement of ChE/BioChE students in industry after graduation with a B.S.in ChE. Survey conducted by AICHE in 2015; this chart only reflects industry job placement(48.9% of students) and does not include the 22.9% of students that enter graduate school. Since such a large fraction of BioChE students pursue jobs in biotech/pharma, it isimportant that we prepare our graduates for those fields by training them with a wide range ofmodern biotechniques. For example, many jobs in the biotech sector require engineers to culturebacterial or animal cells, manipulate DNA to synthesize new genes or sequence existing genes,and purify

Indeed, further analysis is needed to identify the specific types of cultures thatchemical engineering departments across the US foster, how (re: episodes) such a cultureis cultivated, and whether it is effective from both a faculty (category 3) and student(category 1) perspective.

In the laboratory, studentsfailed to use techniques to reduce experimental error when necessary. Data were often notreported correctly to reflect uncertainty in measurement, and simple statistical techniques wererarely used to analyze error.A variety of methods for the introduction of error analysis to lower level engineering studentshave been described by other educators.

foreach user’s account (Figure 2). Although this is an imperfect metric since students often watchvideos together and this is logged only in one student’s account, students who benefit from theability to re-watch lecture material would presumably have a large number of video watchesand/or a large cumulative duration of video watching. Figure 2 shows that contrary to ourhypothesis, students who spend the most time watching videos do not perform better thanstudents who watch the assigned videos only once (59 videos, 17.6 hours). It is, however,important to note that the number of videos watched probably only reflects video loads, andwould not capture multiple watches of the same segment, so there could still be a hiddencorrelation, but this data

. Anecdotally, the instructor notesthat during the lab activities, the students would attempt to complete the instructions as quicklyas possible, spending little time analyzing and reflecting on the unit operation or the meaning oftheir own actions. For the demonstrations, students merely watched a TA point out importantparts of the equipment. The equipment was not always even turned on. In these situations, thestudents did not interact personally with the equipment in any way.The course revisions utilized a more project-based learning approach. For each of three unitoperations, students were given a semi-ambiguous set of goals (e.g., find the column efficiencyrelative to flowrates) and three four-hour lab sessions with which to find the necessary data
