Innovations in undergraduate education have increased the prevalence of active learning courses, online education, and student engagement in the high-impact practice of undergraduate research, however it is unknown whether students with disabilities are able to engage in these innovative learning environments to the same extent that they are able to engage in more traditional learning environments. Universities, disability resource centers, and instructors are mandated to provide accommodations to students with disabilities for the purposes of prohibiting discrimination and ensuring equal access to opportunities for individuals with disabilities. Are accommodations being adapted and created for these new types of learning environments? This dissertation reports findings from four studies about the experiences of students with disabilities in these three learning environments, specifically examining the challenges students with disabilities encounter and the emerging recommendations for more effective accommodations. I find that students with disabilities experience challenges in each of these learning environments and that the current suite of accommodations are not sufficient for students with disabilities. I argue that institutions need to consider modifying student accommodations and the process for obtaining them to better support students with disabilities in these evolving learning environments. I also provide recommendations for the ways in which undergraduate science education can be made more accessible and inclusive of students with disabilities.
