Winter, Julia E.; Engalan, Joseph; Wegwerth, Sarah E.; Manchester, Gianna J.; Wentzel, Michael T.; Evans, Michael J.; Kabrhel, James E.; Yee, Lawrence J. – Journal of Chemical Education, 2020
The mechanism maps that guide student instruction in organic chemistry curricula are structural representations of bond-breaking and bond-making events that transform a reactant into a product. For students, these pathways represented by electron pushing formalism (EPF) can be challenging to navigate. For instructors, providing formative feedback…

Ylostalo, Joni H. – Journal of Biological Education, 2020
Students in a mixed majors undergraduate microbiology class often struggle with basic genetics concepts, generating gaps in their overall understanding of genetics. This can be a result of employing the traditional block style of instruction that focuses on teaching skills and concepts one topic at a time. Here I present a simple, yet innovative…

Valle-Suárez, R. M.; Calderón-Mendoza, G. L.; Lanza-Sorto, N. A.; Ponce-Rodríguez, H. D. – Journal of Chemical Education, 2020
Significant changes in the teaching-learning process have occurred since the appearance of the COVID-19 pandemic caused by the SARS-CoV 2 coronavirus, due to the limited mobility and closure of university education centers. In this context, essential challenges were presented for teachers and students to finish the academic courses by addressing…

Sengul, Ozden – School Science Review, 2020
This article describes the implementation of an activity with a Predict-Observe-Explain (POE) learning cycle to teach the concepts of velocity and acceleration to physics students aged 17-19. The study indicates how the instructor enacted the activity and provides sample student responses and group discussions. The description includes an example…

Horn, Ivo R.; Verleg, Peter A.; Ibrahim, Nafiesa Z.; Soeleman, Khadiedjah; Kampen, Floris; Ruesen, Mia O.; Reulen, Naïsha M.; Breij, Henk; Bakker, Roderick J.; Gravendeel, Barbara – Biochemistry and Molecular Biology Education, 2020
DNA barcoding is an important molecular methodology for species identification that was developed over the last two decades and it should be covered in the biology bachelor curriculum. Here, we present an example of DNA barcoding by sequencing a segment of the 28S nuclear ribosomal large subunit rRNA gene of wild mushrooms and framing the…

Hills, Melissa; Harcombe, Kimberley; Bernstein, Nina – Biochemistry and Molecular Biology Education, 2020
Anticipated learning outcomes (LOs) were defined and used for the backward design of a Course-based Undergraduate Research Experience (CURE). These LOs reflect the inquiry-based nature of CUREs and capture key knowledge and skills inherent to scientific practice and essential in research. The LOs were used to plan a formative and summative…

Atieh, Emily L.; York, Darrin M. – Journal of Chemical Education, 2020
The Teaching Internship is a credit-bearing program composed of undergraduate near peer instructors (teaching interns, or TIs) that offers supplemental assistance for students in the General Chemistry courses. With fellow undergraduates serving as a role model and student--faculty liaison, the benefits of near peer instruction have been…

Zhou, Chun – Biochemistry and Molecular Biology Education, 2020
In the spring semester of 2020, colleges and universities adopted online teaching as the primary modality due to campus closure for social distancing. While lectures could be more readily converted to online classes, biology labs were challenging to handle since students could not physically conduct experiments in lab classrooms. In the present…

Megan; Straub, Jacob N.; Bunnell, Sarah L.; Witkovsky-Eldred, Marissa – Scholarship and Practice of Undergraduate Research, 2020
Multisite, course-based undergraduate research experiences (CUREs) in the Ecological Research as Education Network (EREN) were assessed for impacts on student learning of collaborative science skills using a survey that could serve as a starting point for a validated assessment instrument for multisite CUREs. Pretests/posttests were administered…

Rogers, Bradley A.; Zhang, Yanjie – Journal of Chemical Education, 2020
The Hofmeister series is a recurring trend that ranks ions' abilities to influence various aqueous processes in solution. Herein, a set of project-based experiments was developed for students in an upper-level physical chemistry laboratory to investigate the specific ion effects on the thermodynamics of caffeine partitioning between aqueous and…

Nielsen, Wendy; Georgiou, Helen; Jones, Pauline; Turney, Annette – Research in Science Education, 2020
Assessments in tertiary science subjects typically assess content knowledge, and there is current need to both develop and assess different forms of knowledge and skills, such as communications and digital literacies. A digital explanation is a multimodal artefact created by students to explain science to a specified audience, which is an…

Schmidt, Emily; Vik, Ryan; Brubaker, Benjamin W.; Abdulahad, Sienna S.; Soto-Olson, Diana K.; Monjure, Tia A.; Battle, Cooper H.; Jayawickramarajah, Janarthanan – Journal of Chemical Education, 2020
There is a growing need for workers with STEM-aligned training in the modern global economy, but a paucity of workers to fill these positions. One important contributor to this issue is low student persistence in STEM. Nontraditional science courses that utilize more active-participation and learning are attractive as tools to increase student…
