In addition, the partially sighted student may use large print books, closed circuit TV magnifier, or a large print typewriter. There are two basic difficulties that the partially sighted student is confronted with that the blind student is not. Since this student does not use a white cane or guide dog, people have difficulty believing that the student needs to use adaptive methods when using print materials. Another difficulty is more subtle - the psychological response that large print evokes in the sighted reader. Instructors sometimes assume the partially sighted student is only trying to make an assignment longer.
Most blind student use a combination of methods including readers, audio taped books and lectures.
Students may use raised drawings or diagrams, charts, and illustrations, relief maps, three-dimensional models of physical organs, shapes, etc. Talking calculators and reading machines are beneficial to students, although not often readily available. Some faculty members are concerned about having their lectures tape- recorded. Some blind students use service dogs. Dog guides will not disturb the class.
