An introduction to the chemistry of biological, inorganic, and organic molecules with emphasis on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis.
The Drennan Lab originally developed this training on stereotype threat and unconscious bias for 5.111 Principles of Chemical Science and other Chemistry Department teaching assistants (TAs).
Prof. Drennan introduction on the TA Training program.
In this video, Catherine Drennan discusses the central role of Teaching Assistants in the course, and how she developed an application and training program to foster enthusiasm among incoming graduate students for teaching introductory chemistry.
In this video, Catherine Drennan explains how Pizza Forums create opportunities in this large lecture course to get to know students on a personal level and to learn what's working and what's not working well in the course.
In this video, Catherine Drennan explains how she uses humor to engage students and to help them remember curricular content.
In this video, Catherine Drennan explains how she uses clicker questions and demonstrations to promote active participation during lectures.
In this video, Catherine Drennan describes how introducing clicker competitions increased student effort and engagement in the course; it also seemed to foster a sense of community among students in this large lecture class.
In this video, Catherine Drennan shares how she prepares for lectures. She reviews note-taking handouts, plans the sequence of activities, develops demonstrations, and coordinates her t-shirts with lecture content to infuse the course with a sense of fun.
In this video, Catherine Drennan discusses how she spotlights contemporary chemists in the course as a way to communicate to students that chemistry is a modern subject that can be used to make the world a better place.
In this video, Catherine Drennan notes that 5.111 Principles of Chemical Science is a class in which students can discover their passion for chemistry, or plant the seeds for later understanding chemistry's central role in many fields.
