The lack of diversity in the computing education pipeline has been a remarkably persistent problem. Something that’s stalled progress in addressing disparities is that there’s largely been a focus on individuals, such as teachers and students, rather than on how equity plays out across multiple levels of the computer science (CS) education ecosystem. This is why our work at the University of Texas since 2014 focuses on understanding the root causes of inequities in the CS education pipeline and how every level of the system influences equity.
With the support of a CS-ER (computer science education research) grant from Google, my colleague Jayce Warner and I developed a framework for thinking about equity across the CS education ecosystem. We began this work after digging into data in Texas in 2014 and finding that only about a quarter of Texas high schools offered any kind of CS course and fewer than 3% of Texas students were taking a CS course each year. The students enrolled in CS courses were also not reflective of the student population in our diverse state. We launched what became the WeTeach_CS professional development program, with the ultimate objective of seeing equitable enrollment in CS courses in Texas. To achieve this goal, we first had to improve access to CS courses and increase the number of CS-certified teachers in the state.
At the time, we thought equity had to wait until we had solved the capacity, access and participation challenges. But as we began thinking more deeply about this model and asking our colleagues in the Expanding Computing Education Pathways (ECEP) Alliance for feedback, we realized several things:
True Equity is about more than just diversity in the classroom, and just because something is available to everyone doesn’t mean that everyone can or will benefit. Also, education is very complex and the things we can easily measure (such as AP class participation) may not be the best indicators of change or success.
We developed a new framework that reflects how things connect at different levels of CS education. Most importantly, this model helps us better understand how equity plays out at each level. We’ve called it the CAPE framework and it consists of four interdependent components: capacity for CS education, access to CS education, participation in CS education and experience of CS education.
Each level affects the next. For example, if we want students to have equitable experiences in CS, we first need to make sure they’re participating equitably. Equitable participation relies on equitable access and equitable access relies on equitable capacity.
