The development, testing, and classroom implementation of a low-cost, reproducible, desktop sized, highly visual double-pipe heat exchanger are presented. Quantitative measurements with the module reveal its usefulness for demonstrating basic and advanced convective heat transfer theory while worksheet-guided inquiries promote student engagement.…

This study evaluates students' outcomes in an online materials and energy balances course during the COVID-19 pandemic. Using multiple linear regression, we found that students' "competence" and "autonomy" beliefs decreased across the semester, with a negative change in competence beliefs predicting higher grades for students,…

In an effort to offer modern and engaging senior design projects, as well as to improve ABET student outcome achievement, students were tasked with proposing their own design project idea for potential use as a senior project. Survey results from two cohorts have indicated that the majority of the students felt they achieved targeted ABET student…

Textbooks are experiencing a 21st century makeover. The author has created a web-based electronic textbook, Material and Energy Balances zyBook, that records students' interactions. Animations and question sets create interactive and scaffolded content. The interactive format is adopted successfully in other engineering disciplines and is now…

Heat and temperature concepts are found at all levels in the science curricula and are well-known for creating conceptual difficulties for learners. Students have difficulty understanding concepts related to heat, temperature, and thermal radiation. Inquiry-based pedagogies that can foster the learning of these difficult concepts are needed.…

We surveyed 342 first-year engineering students at four U.S. institutions interested in a chemical engineering career about their feelings of belonging in engineering, motivation, and STEM identities. We compared these students by both gender and race/ethnicity on these attitudinal factors. We found several significant differences in…

A sophomore core chemical engineering course was co-taught by two different 4 instructors in Spring 2016 and Spring 2017 with approximately 90 students both semesters via an 5 active learning environment in a collaborative learning space. Both instructors were present for 6 almost all lectures and each instructor delivered approximately 50% of the…

Using a large multi-institutional dataset, we describe demographics and outcomes for students starting in and transferring into chemical engineering (ChE). In this dataset, men outnumber women in ChE except among black students. While ChE starters graduate in ChE at rates comparable to or above their racial/ethnic population average for…
