The definition of legal blindness covers a broad spectrum of visual impairments. (Carim, 2006) The extent of visual disability depends upon the physical sensory impairment of the student’s eyes, the age of the student at the onset of vision impairment, and the way in which that impairment occurred. Vision also may fluctuate or may b e influenced by factors such as inappropriate lighting, light glare, or fatigue. Hence, there is no “typical” vision impaired student.

The major challenge facing visually impaired students in the science educational environment is the overwhelming mass o f visual material to which they are continually exposed as. , textbooks, class outlines, class schedules, chalkboards writing, and many more In addition, the increase in the use of films, videotapes, computers, laser disks, and television adds to the volume of visual material to which they have only limited access.

Be specific in directions and avoid the use of vague terms with unusable information, such as “over there”, “here”, “this” and the teachers must describe in detail, pertinent visual occurrences of the learning activities. (Carim, 2006) Teachers were also advised to describe and tactually familiarize the student to the classroom, laboratory, equipment, supplies, materials and field sites.

It is also advisable as a teacher to identify themselves by name, and never to assume that the student who is visually impaired will recognize you by your voice even though you have met before.
