In identifying a student who may have a hearing loss, therefore, teachers need to observe the student over an extended period of time and in as many situations as possible. In particular, look for a persistent combination of some of the following, but look for them over repeated or numerous occasions (Luckner&Carter, 2001):

  • delayed language or literacy skills, both written and oral
  • some ability (usually partial) to read lips
  • less worldly knowledge than usual because of lack of involvement with oral dialogue and/or delayed literacy
  • occasionally, tendency to social isolation because of awkwardness in communication

Teaching students with hearing loss

In principle, adjustments in teaching students with hearing loss are relatively easy to make though they do require deliberate actions or choices by the teacher and by fellow students. Interestingly, many of the strategies make good advice for teaching all students!

  • Take advantage of the student’s residual hearing. Seat the student close to you if you are doing the talking, or close to key classmates if the students are in a work group. Keep competing noise, such as unnecessary talking or whispering, to a minimum (because such noise is especially distracting to someone with a hearing loss). Keep instructions concise and to-the-point. Ask the student occasionally whether he or she is understanding.
  • Use visual cues liberally. Make charts and diagrams wherever appropriate to illustrate what you are saying. Look directly at the student when you are speaking to him or her (to facilitate lip reading). Gesture and point to key words or objects—but within reason, not excessively. Provide handouts or readings to review visually the points that you make orally.
  • Include the student in the community of the classroom. Recruit one or more classmates to assist in “translating” oral comments that the student may have missed. If the student uses American Sign Language (ASL) at home or elsewhere, then learn a few basic, important signs of ASL yourself (“Hello” “thank you” “How are you?”). Teach them to classmates as well.

Visual impairment

Students with visual impairments have difficulty seeing even with corrective lenses. Most commonly the difficulty has to do with refraction (the ability to focus), but some students may also experience a limited field of view (called tunnel vision) or be overly sensitive to light in general. As with hearing loss, labels for visual impairment depend somewhat on the extent and nature of the problem. Legal blindness means that the person has significant tunnel vision or else visual acuity (sharpness of vision) of 20/200 or less, which means that he or she must be 20 feet away from an object that a person with normal eyesight can see at 200 feet. Low vision means that a person has some vision usable for reading, but often needs a special optical device such as a magnifying lens for doing so. As with hearing loss, the milder the impairment, the more likely that a student with a vision problem will spend some or even all the time in a regular class.

Signs of visual impairment

Students with visual impairments often show some of the same signs as students with simple, common nearsightedness. The students may rub their eyes a lot, for example, blink more than usual, or hold books very close to read them. They may complain of itchiness in their eyes, or of headaches, dizziness, or even nausea after doing a lot of close eye work. The difference between the students with visual impairment and those with “ordinary” nearsightedness is primarily a matter of degree: the ones with impairment show the signs more often and more obviously. If the impairment is serious enough or has roots in certain physical conditions or disease, they may also have additional symptoms, such as crossed eyes or swollen eyelids. As with hearing loss, the milder forms ironically can be the most subtle to observe and therefore the most prone to being overlooked at first. For classroom teachers, the best strategy may be to keep track of a student whose physical signs happen in combination with learning difficulties, and for whom the combination persists for many weeks.

Teaching students with visual impairment

In general, advice for teaching students with mild or moderate visual impairment parallels the advice for teaching students with hearing loss, though with obvious differences because of the nature of the students’ disabilities.

  • Take advantage of the student’s residual vision. If the student still has some useful vision, place him or her where he can easily see the most important parts of the classroom—whether that is you, the chalkboard, a video screen, or particular fellow students. Make sure that the classroom, or at least the student’s part of it, is well lit (because good lighting makes reading easier with low vision). Make sure that handouts, books and other reading materials have good, sharp contrast (also helpful with a visual impairment).
  • Use non-visual information liberally. Remember not to expect a student with visual impairment to learn information that is by nature only visual, such as the layout of the classroom, the appearance of photographs in a textbook or of story lines in a video. Explain these to the student somehow. Use hands-on materials wherever they will work, such as maps printed in three-dimensional relief or with different textures. If the student knows how to read Braille (an alphabet for the blind using patterns of small bumps on a page), allow him to do so.
  • Include the student in the community of the classroom. Make sure that the student is accepted as well as possible into the social life of the class. Recruit classmates to help explain visual material when necessary. Learn a bit of basic Braille and encourage classmates to do the same, even if none of you ever become as skilled with it as the student himself or herself.
