Hello! I’m Dr. Kathleen Offenholley. I live in Brooklyn, NY. I’ve been teaching math for 20 plus years. Recently, I was one of five faculty at BMCC to be recognized with a distinguished award. I was also featured in Marks of Excellence and in an article in the Hechinger Report. Besides teaching, my main interests include quilting and karate. There’s an article on the CUNY math blog about me that includes a picture of my favorite quilt, and talks about my karate school, which is part of an anti-violence organization that teaches self defense.

My current research interests include gaming in mathematics education and work on an NSF grant on Algebra Concepts. I am a former steering committee member of CUNY Games Network, which connects educators from every campus and discipline at CUNY who are interested in games, simulations, and other forms of interactive teaching. http://games.commons.gc.cuny.edu/

My Blog on games in math education can be found here.

Three amazing digital games for algebra and pre-calculus are here.

Honors, Awards and Affiliations

I was given the distinguished teacher award at BMCC in 2019:

Professors Recognized for Unique Contributions to Student Learning

Additional Information

My dissertation was a discourse analysis of online learning, including how student and teacher interaction influences the online conversation. One of my findings: when teachers talk more online, students tend to talk more, too — but if teachers take up more than a certain proportion of the conversation, students talk less. I also found that when teachers use a sort of Socratic questioning style, encouraging students and asking them questions, students tend to interact more with each other, with longer thread lengths.
