Summary

This presentation explores two topics. First, this presentation covers the iterative development of the Student Perceptions of Accessibility (SPA) scale for online instructional materials. Second, this presentation highlights a significant and positive relationship between perceived accessibility and student success. The development of the SPA scale will enable systematic evaluations of perceived accessibility, significantly enhancing opportunities for accessibility research and practice.

Abstract

Students enrolled in online courses rely heavily on instructional materials such as documents, videos, images, assignments, and learning management systems. By law, these materials must be accessible. Surprisingly, however, no existing instrument measures student perceptions of the accessibility of instructional materials. To address this gap, the researchers developed the Student Perceptions of Accessibility (SPA) scale based on the Web Content Accessibility Guidelines (WCAG) principles of perceivable, operable, understandable, and robust materials. Results of several iterations of item development and factor and reliability analysis suggest the SPA scale is a reliable, valid measure of perceived accessibility of instructional materials.

During the scale development process, the researchers also examined the relationship between perceived accessibility of instructional materials and student success. For example, results of a regression model constructed during pilot testing suggest perceived accessibility is a significant and positive predictor of perceived learning for college students with disabilities (n = 116).

Overall, the SPA scale constitutes a promising instrument for measuring perceived accessibility of instructional materials. This study also provides some of the first systematic evidence of a relationship between accessibility and student success. Recommendations for further research and the relevance of the SPA scale for practitioners are discussed. The presenters also invite participants to provide feedback on the SPA scale items and contribute to an interactive discussion about the scale.

Keypoints

  1. The Student Perceptions of Accessibility (SPA) scale is a reliable, valid measure of perceived accessibility.
  2. Perceived accessibility of instructional materials is a significant predictor of student success.
  3. The SPA scale offers substantial utility for accessibility research and practitioners.
