THE TYPE-TOKEN RATIO AND VOCABULARY PERFORMANCE

The Type-Token Ratio (TTR), a measure of lexical diversity, was correlated with four measures of vocabulary performance: the Peabody Picture Vocabulary Test-Revised, the Oral and Picture subtests of the Test of Language Development, and the Test of Written Language. The vocabulary tests were administered to 21 6-, 7-, and 8-yr.-old children from whom language samples were obtained for the application of three Type Token Ratio measures: the TTR-Total for the whole language sample, the TTR-100 for language samples of 100 words, and the CTTR, a procedure intended to be independent of language sample size. One correlation of .45 (between the CTTR and the Oral-TOLD) was significant. More research on validity is necessary to clarify the measurement domain of the TTR, if it is to be useful clinically.

EFFECT OF A GROUP PERCEPTUAL-MOTOR TRAINING PROGRAM ON KINDERGARTEN CHILDREN

For 21 boys and 24 girls in a middle-class kindergarten no differences in Identification of Body Parts, Copy Forms, or Motor Skills Test of the Rosner-Richman Perceptual Survey were noted. Scores increased from September to May testing on copying and motor skills, e.g., walking a rail, balancing, handling balls, as expected.

Teacher Self Concept and Student Self Concept in Grades Three, Four, and Five.

AbstractThis research examined the theory that a teachers level of self concept is related to the development of selected aspects of self concept in students in grades 3, 4, and 5. An analysis of variance of residual gain scores was employed to test the significance of the relationship. The evidence suggests that teacher self concept has an effect upon the development of the students self concept in the case of two of the four dimensions tested.

The Principal's Power Tactics Survey: The Measurement of Administrative Power Strategies of Elementary School Principals

Measurement instruments for the use of administrative power strategies in schools are not available. The purpose of the present study was to develop an instrument to measure the power strategies of elementary school principals. The researchers developed an instrument to measure the overall strategies of Personal Power and Position Power as well as the subsidiary strategies of Assertiveness, Sanctions, Upward Appeal, Ingratiation, Rationality, Exchange, and Coalition. A sample of 297 teachers provided data about 50 principals. After psychometric analysis, the instrument was determined reliable and valid enough for research purposes although further psychometric analyses were recommended.

UNIQUE: A Regression Analysis of the Uniqueness and Specificity of Predictor Variables and Sets.

MULTIPLE regression analysis affords a convenient means of examining different variables or groups of variables for clues for future research as well as answers to existing problems. Setwise regression analysis (Williams and Lindem, 1971) allows a stepwise solution for sets of variables. The setwise procedure eliminates sets of variables in a stepwise fashion with the drop in the R2 (coefficient of determination) used as the criterion to eliminate set. Unique examines the particular contributions variables or set of variables, as specified, to the prediction system. However, the stepwise procedure is eliminated. Following computation of the R2 value to which all variables have a chance to contribute, a portion of the prediction system is omitted as directed and the remaining variables used to recompute the R2 value. The difference in these R2values (full minus restricted prediction system) may be interpreted as an estimate of how much criterion variance
