Transition Multiple-Choice Exams Online: A Large-Enrollment Solution

by Diana Leung, Department of Chemistry and Biochemistry In 2020 the changes brought about by COVID-19 forced me to transition my normally face-to-face classes to an online format. This fall semester I teach two sections of a freshman Introductory Chemistry class (CH 104), each with about ~200 students, and an Organic Chemistry II (CH 232)

Electronic Whiteboard Options for Online Lectures: iPad & Zoom or Blackboard Collaborate Ultra

by Diana Leung, Department of Chemistry and Biochemistry I am an Associate Professor in the Department of Chemistry and Biochemistry at The University of Alabama. After the need for social distancing due to COVID-19, I had to transition my face to face classes to an online format. My teaching style relies crucially on the use

Details and Procedures: Returning Hand-Graded Exams Electronically

This post details the grading process described in “Scan and Deliver! Personalized Feedback in Large Classes.” We printed individual labels with each student’s name; on each label, the corresponding CWID was encoded in a Code 39 barcode. We used standard 1″ x 2 5/8″ addressing labels, 30 per page, for which MS Word has built-in templates.

Scan and Deliver! Personalized Feedback in Large Classes

by Marco Bonizzoni and Diana Leung, Department of Chemistry Organic chemistry is a surprisingly visual discipline. Molecules, the fundamental entities of chemistry, exist as 3D objects whose shapes often profoundly influence their properties, so students must learn the visual language of the discipline, which attempts to convey the nature of these three-dimensional objects through two-dimensional drawings.

Visual Thinking in Organic Chemistry

Instructor: Marco Bonizzoni Course: Organic Chemistry (CH 231 & 232) Audience: Undergraduates Organic chemistry is the study of the properties and behavior of chemicals containing carbon as the key element. These compounds are both the basis of all life on earth (we are all made of organic compounds) and a large focus of the chemical
