Elizabeth Patitsas

About me

I'm a PhD candidate at the University of Toronto, studying computer science education. My research interests include gender issues in computer science education, how CS departments make policy decisions about their undergraduate programmes, and how instructors (and TAs) understand their teaching practices.

Contact: my last name @cs.toronto.edu

Office: BA 4202

Pronunciation in IPA: any of /pa'titsas/ (pah-TEET-sahs), /pəˈtitsəs/ and /pʌˈtitsəs/ are good with me. (The original Greek is Πατίτσας.)

Published experience reports and teaching demos

Research Publications

On diversity in CS (2013-present)

Looking at organizational, systemic change affecting diversity in computer science.

CS grades aren't bimodal! (2013-present)

Statistical analysis of CS grade distributions; how instructors perceive their grade distributions (with Jesse Berlin).

Past Projects

On adding social context to CS (2012-2013)

I participated in an ITiCSE 2012 working group on 'Computing for Social Good', focusing on sharing CS1 assignments with social context. Providing social context to CS1 is beneficial for many students -- and disproportionately so for underrepresented groups.

On CS1/2 assessments (2013)

I participated in an ITiCSE 2013 working group on collecting and categorizing CS1/2 multiple choice questions.

On using compare+contrast to teach CS2 (2012-2013)

This work was from my Master's thesis. We found that teaching variants of data structures side-by-side, and having students compare and contrast the different data structures led to more student learning than if you present the different data structures sequentially.

On supporting teaching assistants (2009-2011)

Most of this work came out of my undergraduate thesis, which was a qualitative evaluation of teaching assistant experiences in teaching CS at UBC.

On teaching digital logic (2008-2012)

How do we make digital logic labs interesting and engaging for students? I was part of a project to redevelop the lab curriculum for the digital logic course at UBC. During the process I surveyed students and TAs about the labs, to evaluate the curriculum changes.

Outside my academics, I enjoy rock climbing (mostly indoors), playing strategy board games (my collection), cooking vegan food, and gardening.

Whenever I get the chance, I also love hiking, scrambling, snowshoeing, cross-country skiing, and any other excuse to be around mountains and forests.


These are my cats -- on the left is Geordie, and on the right is his sister Marjane ('Marjie'):

I adopted them as kittens through Annex Cat Rescue. They've been with me since September 3, 2013; and were born on May 24, 2013. I have many, many more photos of them.

Academic Fun

I keep a blog, Feminist Computer Science Education. My twitter handle is @patitsel. I'm also on ResearchGate, ORCID and Academia.edu.

I have an Erdős Number of 4 (Me -> Steve Wolfman -> Richard Anderson -> László Lovász -> Paul Erdős).
