Designing a Remote, Synchronous, Hands-On General Chemistry Lab Course

Abstract

The development of a remote, synchronous general chemistry lab course, which was offered to 800 students in the fall semester of 2020, is described. The course was designed with similar curricular goals as our in-person lab course and featured chemistry kits developed by a team of faculty, staff, and graduate TAs. The kits, which were distributed via a rental program through the university bookstore, provided students the opportunity to conduct hands-on experiments at home or in their dorm room. To create the remote lab course, the team negotiated logistical and curricular issues such as finding alternatives to costly precision glassware and instrumentation, adding strategies for engaging students online, decreasing chemical hazards of experiments, and encouraging a safety culture for students working remotely. A professional development graduate course for TA instructors, associated with the general chemistry lab program, was also enhanced by including topics that were relevant for understanding remote learning environments. In redesigning the lab course for remote delivery, we developed new experiments (e.g., calibration), introduced new engagement strategies (e.g., badging), revised several experiments (e.g., heats of reaction), included an Arduinobased spectrometer (e.g., visible spectroscopy and pulse oximetry), and provided new student supports (e.g., TAs on-call). Survey data was gathered to assess student evaluation of the hands-on activities, the presence of synchronous TA help, the badging experience, the value of the lab course, and challenges faced in taking the lab course during a pandemic.

“…Online lab exams derived inflated results. Similar results were argued in previous findings , that explained the value-added to hands-on laboratory experience training compared to without it. Furthermore, online learning is crucial to acquiring learning loss.…”

CoLab: A Workshop-Based Undergraduate Research Experience for Entering College Students

“…As a specific example relevant to the current challenges of teaching laboratory online, , this paper focuses on the activities for the 2020 and 2021 CoLab programs. In 2020, we implemented an entirely online set of activities using molecular visualization with PyMOL 2.5 to observe interactions of small molecules bound to proteins (elaborating on the work of Acuna et al).…”

Creating Representation in Support of Chemical Reasoning to Connect Macroscopic and Submicroscopic Domains of Knowledge

“…Lab reports offer students opportunities to reflect on and write about chemistry following their laboratory experience. It is also important to recognize that, even though students are asked to generate their own ideas, instructors play a key role in facilitating understanding. , Thus, professional learning experiences for the TAs are part of successful delivery of inquiry-based approaches. − …”
