The presentation will begin with an overview of the Cognitive Theory of Multimedia Learning (CTML). It will then provide an introduction to the online tutorial designed for d/Deaf and hard-of-hearing (DHH) students. Finally, we will present student survey responses to the tutorial within the framework of CTML design principles.


COVID-19 has ushered in a new era of online education. Traditional multimedia instruction employs both pictures and words as a standard e-learning resource. The Cognitive Theory of Multimedia Learning aids in the design of these resources to engage the active processing of the learner. However, this theory is partly based on the dual-channels principle (learners both see and hear information) from cognitive science. Faculty members who teach d/Deaf and hard-of-hearing (DHH) students are challenged to develop multimedia instruction that aligns with these design principles. The current project recruited DHH students to watch a chemistry multimedia tutorial that was voiced, captioned and signed to maximize access to content. Participants were then asked to provide their perspectives on the features that helped and hindered their learning. Perspectives are presented within the theoretical framework and provide novel insight into how it might best be adapted for this student population.


  1. Students that are d/Deaf or hard of hearing (DHH) disproportionately elect to participate in online education.
  2. The cognitive theory of multimedia learning supports effective learning with multimedia educational resources.
  3. Students that are d/Deaf or hard of hearing (DHH) have not been considered in the design of CTML.
