MATH PERFORMANCE OF HEARING IMPAIRED CHILDREN

While I am seeking knowledge of appropriate methods to teach hearing impaired children, I believe it is important to note characteristics of educational performance in these children, so we can understand the norm. So far in my reading, I have learned the following:

• The average hearing impaired 10 year old performs 2 years behind his/her grade level
• The average 15 year old performs 4-5 years behind his/her grade level
• 90% of hearing impaired 15 year olds in the USA are given a Stanford Achievement Test (SAT) lower than their grade for mathematics.
• The average score for Hearing Impaired children when given the SAT test appropriate for their grade level is comparable to the scores of the lowest 2% of students w/o hearing impairment
• In 3 studies comprised of more than 500 children with levels of hearing impairment ranging from the most mild to profound, there was NO CORRELATION OF THE LEVEL OF HEARING IMPAIRMENT TO THE SEVERITY OF POOR PERFORMANCE IN MATHEMATICS.
