Paper presents a method developed for deaf students to record and stream lecture slides for later retrieval and review. A two-minute lecture about the human visual system was recorded and streamed using smart phones, selected because of their built-in video cameras. Participants were 17 students aged 20 to 45 years, 9 of whom were female, who had requested accommodations in the classroom. The lecture was presented to participants using two different approaches: (1) showing the instructor speaking while simultaneously referring to information on the slides used, and with a close-up of the sign language interpreter also streamed; and (2) each time following the instructor speaking about the slide information, rewinding the video to the previous slide and replaying the video segment. After viewing each presentation, participants were asked to respond to two reference questions using a 1 to 5 Likert scale, regarding the simultaneous versus the sequential view, and their level of confidence in being seated at the back of the classroom during the lecture. Two questions were also asked about information that was presented on the slides after the presenter stopped speaking, and about information that was presented simultaneously with the slides. The real-time rewind feature significantly aided students in lecture content capture and recall. The students also liked the ability to sit anywhere in the classroom while still being able to view classroom information clearly.
