Biology education research provides important guidance for educators aiming to ensure access for disabled students. However, there is still work to be done in developing similar guidelines for research settings. By using critical frameworks that amplify the voices of people facing multiple forms of marginalization, there is potential to transform current biology education research practices. Many biology education researchers are still in the early stages of understanding critical disability frameworks, such as Disability Critical Race Studies (DisCrit), which consists of seven tenets designed to explore the intersecting experiences of ableism and racism. Our Research Methods Essay uses DisCrit as a model framework and pulls from other related critical disability frameworks to empower disabled voices in biology education research. Drawing from existing scholarship, we discuss how biology education researchers can design, conduct, and share research findings. Additionally, we highlight strategies that biology education scholars can use in their research to support access for participants. We propose the creation and sharing of Access and Equity Maps to help plan--and make public--the steps researchers take to foster access in their research. We close by discussing frequently asked questions researchers may encounter in taking on critical frameworks, such as DisCrit.
