The sport of Ultimate has grown from parking lot fun to international competition in its 35 year existence. As in many sports, the team that scores is subsequently on defense. Thus the probability that a team will score next is dependent on which team has scored most recently. Unlike in many other sports, teams switch ends after each score. Thus…

Purpose: To examine concurrently and retrospectively the language abilities of children with specific reading comprehension deficits ("poor comprehenders") and compare them to typical readers and children with specific decoding deficits ("poor decoders"). Method: In Study 1, the authors identified 57 poor comprehenders, 27 poor decoders, and 98…

This article focuses on the empirical effects of cognitive differentiation and persuasive skills on transformational, transaction, and laissez-faire leadership. Subjects (N = 294) completed measures of independent and dependent variables. Findings confirmed prior findings, however some findings reflected differences. Cognitive differentiation was…

The study investigated the applicability of previous experimental research on stereotype threat to operational Graduate Record Examinations® (GRE®) General Test testing centers. The goal was to document any relationships between features of the testing environment that might cue stereotype threat as well as any impact on GRE test scores among…

Results of new research into the anomalous results of the 1986 reading portion of the National Assessment of Educational Progress (NAEP) are reported. The original analysis of the 1986 data indicated that the estimated performance level of 9- and 17-year-old students had dropped dramatically since 1984, whereas the performance of 13-year-olds had…

By examining relationships between a host of national policy, domestic economic, media system, and media infrastructure factors, a study assesses possible predictors for videotape cassette recorder (VCR) penetration across 63 countries. Overall statistical results generated through hypothesis testing indicated that these factors were relatively…

Four discrimination indices were compared, using score distributions which were normal, bimodal, and negatively skewed. The score distributions were systematically varied to represent the common circumstances of a military training situation using criterion-referenced mastery tests. Three 20-item tests were administered to 110 simulated subjects.…

The Pennsylvania Educational Quality Assessment data have consistently shown differences between rural, suburban, and urban schools in terms of performance on goal areas and on important background variables. The most consistent pattern has been demonstrated by achievement on cognitive measures. The analyses reported upon were conducted on the…

Several models for optimizing incomplete sample designs with respect to information on the item parameters are presented. The following cases are considered: (1) known ability parameters; (2) unknown ability parameters; (3) item sets with multiple ability scales; and (4) response models with multiple item parameters. The models are able to cope…

Identifying the effects of the New York State Experimental Prekindergarten Program on the development of children requires that a broad array of data be analyzed. In studying the effects of the program, the evaluation unit is interested in determining whether there is an overall effect, and whether children of different ages and different levels…

IN AN EXPLORATORY STUDY OF LEADERSHIP BEHAVIOR AND THE DIMENSIONS OF INTERACTION BETWEEN EDUCATIONAL ADMINISTRATORS AND THEIR ACADEMIC WORK ENVIRONMENT, ANALYSIS WAS MADE OF MAILED QUESTIONNAIRE RESPONSE DATA FROM A RANDOMLY SELECTED SAMPLE OF 83 SECONDARY SCHOOL PRINCIPALS (83 PERCENT OF 100 SURVEYED) AND TEN TEACHERS FROM EACH RESPONDING SCHOOL.…

A DETAILED ANALYSIS OF THE RETRIEVAL EVALUATION RESULTS OBTAINED WITH THE AUTOMATIC SMART DOCUMENT RETRIEVAL SYSTEM FOR DOCUMENT COLLECTIONS IN THE FIELDS OF AERODYNAMICS, COMPUTER SCIENCE, AND DOCUMENTATION IS GIVEN IN THIS REPORT. THE VARIOUS COMPONENTS OF FULLY AUTOMATIC DOCUMENT RETRIEVAL SYSTEMS ARE DISCUSSED IN DETAIL, INCLUDING THE FORMS OF…

It is unsafe to estimate achievement test norms for fall testing by linear interpolation between norms for the previous spring testing and norms for the following spring. Second grade students were tested in reading and arithmetic in the fall and in the spring to provide pre-test and post-test data for evaluation of academic growth. Three…

The present study devised a computerized assignment-by-preference algorithm for a ninth-grade exploratory curriculum. The problem addressed was one of maximally mapping all students into 8 of 12 vocational programs in terms of their preferences for studying each of the programs and the assignment restrictions established by the school. To minimize…

The topic of differential diagnosis and its application to the use of the Revised Illinois Test of Psycholinguistic Abilities (ITPA) and Wechsler Intelligence Scale for Children-Revised (WISC-R) is discussed. The theoretical bases for differential diagnosis and the properties of assessment instruments with diagnostic properties are presented.…
