TL;DR
This paper identifies cognitive style barriers on GitHub affecting women and redesigns features using a browser plugin, leading to improved performance and self-efficacy for users with these styles.
Contribution
It introduces a novel application of the GenderMag method to identify and fix inclusivity bugs on GitHub, enhancing accessibility for diverse cognitive styles.
Findings
Redesigns improved user performance.
Enhanced self-efficacy for women-like cognitive styles.
Design implications for inclusive social coding platforms.
Abstract
Social coding platforms such as GitHub have become defacto environments for collaborative programming and open source. When these platforms do not support specific cognitive styles, they create barriers to programming for some populations. Research shows that the cognitive styles typically favored by women are often unsupported, creating barriers to entry for woman newcomers. In this paper, we use the GenderMag method to evaluate GitHub to find cognitive style-specific inclusivity bugs. We redesigned the "buggy" GitHub features through a web browser plugin, which we evaluated through a between-subjects experiment (n=75). Our results indicate that the changes to the interface improve users' performance and self-efficacy, mainly for individuals with cognitive styles more common to women. Our results can inspire designers of social coding platforms and software engineering tools to produce…
