Studies in Achievement Testing, Hearing Impaired Students. United States: Spring 1971.
Gallaudet Coll., Washington, DC. Office of Demographic Studies.
Results of three studies based on Stanford Achievement Test data collected during the National Achievement Testing Program for Hearing Impaired Students in Spring, 1971 are reported. Compared in the first study are performance patterns of hearing impaired students on the Intermediate I and Advanced batteries with patterns of hearing standardization groups on the same test levels. Content sub-areas within the subtests are analyzed and areas in which hearing impaired students performed better or worse than the standardization group are identified. Technical problems relating to test construction are noted. In the second study, the discriminative validity of items in five selected subtests of the Intermediate I battery is examined and whether the items effectively distinguished between high and low achieving students is determined. Examples of items for each of the five subtests are presented to show high and low discrimination coefficients. The paragraph meaning and science subtests are said to have the highest proportions of low discriminating items and thus the lowest average discrimination coefficients. Reported last are findings of a reliability study of the Primary II battery which involved use of Alternate Forms X and W for the hearing impaired with a sample of 192 students. The standard errors of measurement and other related data are presented. Included in appendixes are descriptions and limitations of the achievement testing program, testing procedures, and a list of schools and classes that participated in the program. (MC)
