In addition to being challenged emotionally, the participants also revealed the pedagogic and professional
challenges they faced. The first that they defined as an obstacle was the reliance of the teaching process on
visualization. In both institutions, teachers made use of the visual components of the books such as digital books, itools and powerpoint presentations almost in all their classes and believed their positive contribution to the teaching
process. They were bewildered and were not quite sure how to replace those visual aids for the VILs. Therefore, S1
had to rely on his course book printed in Braille alphabet while S2 was provided with the audio CDs of the course
book as he believed he did better by listening.
