Abstract: The entire population of Seminole Indian children at the Big Cypress Reservation school, deep in the Everglades, was administered the Wide Range Achievement Test, the Raven Standard Progressive Matrices, the Draw-a-Person Test, the Bender-Gestalt Test, and speech and hearing examinations. Median achievement in reading, spelling and arithmetic was found to be over one standard deviation below national norms. The older children showed a more serious deficit than the younger group when each group was compared with its respective age norms for reading and spelling, although raw scores on intelligence tests increased steadily with age but remained consistently below norm group medians. The verbal achievement deficit among the older children was attributed to educational and to cultural factors.

(3) Visual Self-Confrontation and the Self-Concept of the Exceptional Child

Abstract: This pilot study explored methods and effects of extending a child’s self-awareness. Eighty children from an exceptional education center were given visual self-confrontation experiences for seven months via photography, mirrors, films and video tape playbacks. A comparison of pre-post test results showed an improvement in recognition of self and other self-concept related variables.

(2) Generosity in Essay Grading

Abstract: The generosity error in grading essay test responses is the bias of assigning too high a grade category. This bias should be reduced by manipulating the nature of the grading categories used.

Fifteen teachers graded 12 themes. The 15 teachers were randomly assigned, five each, to one of three types of rating category procedures. The three procedures were: Conventional (two positive, one neutral, two negative categories); Generosity (three positive, one neutral, one negative category); and Number (5, 4, 3, 2, 1). As expected, the conventional five categories produced a higher score than did the unbalanced five categories recommended by Guilford for offsetting the generosity error.
