The statistical properties of two methods of estimating gain scores for groups in quasi-experiments are compared: (1) gains in scores standardized separately for each group; and (2) analysis of covariance with estimated true pretest scores. The fan spread hypothesis is assumed for groups but not necessarily assumed for members of the groups.…

The feasibility of criterion referenced testing is held to be dependent on the tenability of two postulates: (1) that bias can be controlled in a principled manner from one test to the next; and (2) that one mental process measured by such tests may lawfully interact with another. Without the first postulate, criterion scores could not be…

The Rasch model for test score equating was compared with three other equating procedures as methods for implementing the norm referenced method (RMC Model A) of evaluating ESEA Title I projects. The Rasch model and its theoretical limitations were described. The three other equating methods used were: linear observed score equating, linear true…

The National Assessment of Educational Progress (NAEP) has completed two assessments of mathematics, the first conducted in 1972-73 and the second during 1977-78. Each assessment surveyed the mathematics achievement of American 9-, 13-, and 17-year-olds, using a deeply stratified, multi-stage probability sample design. This report documents…

THREE HEAD START PROGRAMS WERE ESTABLISHED TO INVESTIGATE THE DIFFERENCES BETWEEN FOUR GROUPS OF CHILDREN IN THE AREAS OF INTELLIGENCE, COGNITION AND ACHIEVEMENT, ENVIRONMENT, AND PARENTAL EXPECTATIONS. THE FOUR GROUPS WERE (1) THE SR GROUP IN WHICH THE CHILDRENS' PARENTS SOUGHT OUT ENTRY FOR THEIR CHILDREN IN THE HEAD START PROGRAM, (2) THE SAP…

The twofold objective of this book is to enable the teacher of English to speakers of other languages both to improve his own classroom measures and to make sound assessments of standardized tests which he may from time to time be asked to select, administer, and interpret. Chapters 1 and 2 introduce the general purposes and methods of language…

TO DETERMINE HOW SECONDARY SCHOOL TEACHERS AND PRINCIPALS PERCEIVED SUPERVISORY STIMULI, A 36-ITEM QUESTIONNAIRE WAS ADMINISTERED IN 15 THREE- AND FOUR-YEAR SECONDARY SCHOOLS IN NEW YORK STATE, REPRESENTING A STRATIFIED RANDOM SAMPLE ACCORDING TO STUDENT POPULATION, GEOGRAPHIC LOCATION, AND STATUS AS A CITY OR VILLAGE SCHOOL DISTRICT. RESPONDENTS…

This study compared the ability of the ACT Assessment Battery (ACT), the Scholastic Aptitude Test (SAT), and six other variables to predict first semester Grade Point Average (GPA) at the University of Illinois at Urbana-Champaign, a "highly selective midwestern university". Additional purposes were to determine: (1) the effect of using…

Two Basic Skill Centers were set up on 1968 to help inner city students improve their reading skills. The Centers were supported mainly by the Minneapolis Public Schools although ESEA Title I funds provided teacher aides. This report covers the sixth year's operation of the project. Substantial changes in the Centers' operations are described. The…

Two Basic Skill Centers were set up in 1969 to help inner city students improve their reading skills. The centers were supported mainly by the Minneapolis Public Schools although ESEA Title I funds provided teacher aides. This report covers the fifth year's operation of the project. Substantial changes made in the centers' operations are…

A longitudinal study covering the 1967-68 school year, the second year of a 4-year study, compared the academic achievement of Indian high school students according to types of schools (public and federal), geographic areas (Alaska, Arizona, Nebraska, New Mexico, Oklahoma, South Dakota, and Utah), grade levels (9-12), and sexes. Results of the…

The study presents the results of testing an original obersvation instrument designed to identify a power elite in multiple sessions of two eight-member adult discussion groups. Two questions guided the development of the study: (1) Can a power elite be identified in participation training groups? (2) Can an effective observation instrument with…

The purpose of this study was to determine whether option weighting improved the internal consistency and intercorrelation of the subtests. The differential option-weighting scheme employed in this study is based on one devised by Guttman. The tests were first scored with Guttman-type weights and then with conventional correction-for-guessing…

Comparisons of students' educational performances are usually based on test and examination results. However, for such comparisons to be valid, it is suggested that evaluations must be made on some common basis since many educational and employment decisions are based on these evaluations. Standardized tests, often used when comparisons are to be…

This report analyzes the U.S. results of the 1999 International Association for the Evaluation of Educational Achievement (IEA) Civic Education Study, Phase 2. The study was designed to assess the civic knowledge of 14-year-old students across 28 countries. This report concentrates on the attitudes, actions, and conceptual views of U.S. students,…
