4601 H4 A 9 9" SCHOOL TESTS FOR SCHOOL GRADING AND MEAS- URES OF INTELLIGENCE By Mary F.^Moran ) |-U w i» ^ ^ i» i //ead Teacher, Mass. School for the Feeble-Minded, Waverley, Mass. In placing a newly admitted feeble-minded pupil in school work, before the use of psychological tests, we had to depend entirely on long-drawn out school examinations in reading, arithmetic, spelling, etc., in order to find out just what work he was capable of doing and in which grade or class he should be placed. For this purpose we used the most familiar and commonly known text books on the various subjects — Colburn's arithmetic, Rice's speller, Aldine or Progressive course in reading, etc. For instance in read- ing, a boy would be asked to read a little in the 1st reader, the 2nd reader and the 3rd reader, until the limit of his knowledge of read- ing was reached. In the same way, in number work he would be asked to write simple numbers, then more difficult ones, then to add; multiply; and divide until the limit of his arithmetical knowledge was apparent* In spelling, writing, etc., the same method was employed. This plan required the use of several text books for each pupil, took much time and was a tedious and labo- rious task. The method could not be well standardized and, in fact, no two children were given the same examination and the results with different children were not comparable in any way. It has not been found practical to use this trial and error text book method of school examination for school grading, or for the exam- ination of large numbers of children. The modern psychometric findings tell the teacher approxi- mately what grade of school work the individual defective is ca- pable of doing at the time of , examination, but this information is only approximately correct as all defectives of the same mental age are not capable of doing the same grade of school work. For instance, the majority of our pupils with a mental age of 8 years are in the 3rd grade, but we also have 2 in the 1st grade; 9 in the 2nd grade and 2 in the 4th grade. The Binet test does not tell us in which school grade to place the child. In diagnosis, also, there is a definite need of exact knowledge of the child's ability to do school work. This need is especially felt in an out-patient mental clinic dealing with children, for many of these children or adolescents are borderline or doubtful cases, where the mental age is not sufficiently below the normal average to be conclusive and where information in as many fields as possi- ble is necessary in order properly to judge the mentality of the individual. With these defective children the scholastic perform- ance is most important, especially as to their ability to do the practical arithmetical computations usually done by children of their own age and opportunity; their ability to read and to under- stand what they have read. Within a few years several carefully worked out educational scales have been formulated and applied to large numbers of school children; among the best known are the Ayres hand- writ- ing and spelling scale; the Buckingham spelling scale; the Courtis arithmetic, writing and reading scale; the Gray reading scale; the Starch reading and spelling scale; the Woody arithmetic scale and the Trabue language scale. It is rather difficult to apply any of these scales to the testing of individual children — normal or feeble-minded — either for school grading or for diagnostic purposes. Indeed most of the scales mentioned seem to deal with the average or percental achievements of an entire school grade or class rather than with the work of an individual child. Most of the scales do not have a definite or easily applied rating for each school grade. It would take too long to give and score any entire scale to any one pupil. The result of the test would not give definite information as to the exact school grade or division of a grade in which the pupil be- longs, — as I A or II B, and so on, which is precisely the informa- tion we wish to know. Finally, the majority of the above tests do not test a child below third or fourth grade ability, and it is in the first four grades that most of the feeble-minded children are found. For the above reasons it seemed necessary to arrange a more LIBRARY OF.CO^Gfliss Receiv£o:
