Why some students do not feel that they belong in CS, and how we can encourage the sense that they do belong

One of my favorite papers at ICER 2019 was by Colleen Lewis and her colleagues, and is available on her website. I’ll quote her first:

Does a match between a students’ values of helping society and their perception of computing matter? Yes! A mismatch between a students’ goals of helping society and their perception of computing predicts a lower sense of belonging. And students from groups who – on average – are more likely to want to help society (women, Black students, Latinx students, and first-generation college students), this may be particularly problematic! (pdf)

  • Lewis, C. M., Bruno, P., Raygoza, J., & Wang, J. (2019). Alignment of Goals and Perceptions of Computing Predicts Students’ Sense of Belonging in Computing.Proceedings of the International Computer Science Education Research Workshop. Toronto, Canada.

I want to expand a bit on that paragraph. I often get the question, “Why aren’t more women and URM students going into CS?” We’re seeing female students and students of color leaving/avoiding CS at many stages, e.g., Barb’s deep analysis of AP CS*. Colleen and her collaborators are giving us one answer.

We know that students who have a sense of belonging in computing are more likely to stay in computing. Colleen et al. found that students who found that their values were supported in computing were more likely to feel a sense of belonging. So, if what you want to do with your life matches computing, you’re more likely to stick around in computing. This is the “alignment of goals” and “perceptions of computing” part of the title.

Next step: Students from demographic groups underrepresented in computing were more likely to value community and helping society than other students. These are their goals. Do students see that their goals align with their perception of computing? If so, then you have an increased sense of belonging. Colleen and her colleagues found that If the students who valued community perceived that they could use computing to support communal values, then they were more likely to stick around.

This result is obviously explanatory. It helps us to understand who stays in computing. It also suggests interventions. Want to retain more under-represented students in your CS classes? Help them to see that they can pursue their values in computing. Help them to update their perceptions so that they see the alignment of their goals with computing goals.

But what if you (as the teacher) don’t? This paper suggests future research questions. What if your CS class is entirely de-contextualized and doesn’t say anything about what the students might do with computing? What perceptions do the students bring to the CS class if nobody helps them to see the possibilities in computing? Which student goals align with these perceived goals of computing? We might guess what the answers might be, but it really does call for some explicit research. What are students’ goals and perceptions of computing in most CS classes today?


* Check out Barb’s blog at https://cs4all.home.blog/. As I’m writing this, Barb is finishing up the 2019 AP analysis. The gap between white and Black student pass rates on AP CSP is enormous, far larger than the gap on AP CS A. I’m hoping that she has updates there by the time this post appears.
