To determine whether the range of ability within the classroom has a significant effect on students' performance in mathematics, and to identify the class compositional or instructional characteristics that contribute to differences between homogeneous and heterogeneous classes in terms of mathematics achievement, an analysis was conducted using…

A new testing strategy that provides protection against the problem of having examinees in adaptive testing choose difficulty levels that are not matched to their proficiency levels was introduced and evaluated. The method, termed restricted self-adapted testing (RSAT), still provides examinees with a degree of control over the difficulty levels…

This study assessed whether providing examinees with a choice between computerized adaptive testing (CAT) and self-adaptive testing (SAT) affects test performance in comparison with being assigned a CAT or SAT, and evaluated variables influencing examinee choice of either test form. The relative influences of test type and test choice on examinee…

Data from the Spring 1996 administration of the New Standards Mathematics Reference Examination for Middle Grades were used to examine the instructional validity of the Reference Examination, opportunity to learn, and equity in the context of the California Mathematics Renaissance program. Student (n=1,936) and teacher (n=105) responses to the…

The National Assessment of Educational Progress (NAEP) is a congressionally mandated survey of educational achievement of what American students know and can do, it also includes a yardstick that can be used to evaluate that performance. Results, presented here for the states and the nation, indicate that just over 60 percent of the students in…

The validity of teachers' reports of students' instructional experiences (content exposure or coverage) and content validity of a given course were studied by examining the consistency of reported content coverage for teachers across two consecutive years (1988 and 1989). In addition, the sensitivity of the test to instruction was examined by…

The main purpose of this special issue is to suggest strategies for meeting the mathematical needs of two-year college students in the decade of the 1990s. Since the 20 contributors were free to write about topics that they considered to be appropriate to the intellectual and personal development of all students their papers represent a broad…

This user manual describes procedures for using Version 3.0 Computerized Placement Tests (CPTs) software and provides information about the hardware required to operate it. The software features the College-Level Mathematics (CLM) test, Seamless Serial Testing branching capabilities, new system installation and uninstallation procedures, and new…

This report of the Texas Assessment of Academic Skills (TAAS) Student Performance Results lists performance results on the TAAS and the Texas Educational Assessment of Minimum Skills (TEAMS), an exit examination, alphabetically by school district for each grade level tested (grades 3, 5, 7, 9, 11 for the TAAS and grades 11 and 12 for the initial…

The National Assessment Governing Board (NAGB) of the National Assessment of Educational Progress (NAEP) adopted mathematics achievement standards on May 11, 1991 that will be used to report results on the 1990 assessment of mathematics. NAEP achievement levels are descriptions, based on informed judgments, of what students should know and be able…

Two papers are presented that resulted from the Instructional Assessment Project of the Center for Research on Evaluation, Standards, and Student Testing. Both relate to models for assuring assessment validity. The first paper--"Assessing the Content Validity of Teachers' Reports of Content Coverage and Its Relationship to Student…

Information is provided about the Delaware Educational Assessment Program and the performance of Delaware public school students as measured by a nationally-normed standardized achievement test. The Stanford Achievement Test, Eighth Edition was administered statewide, allowing comparisons with national performance and with the performance of…

Eight hundred and ninety-nine (431 male, 467 female and one missing value) Grade 8 and 9 (n = 184 and 713, respectively, with two missing values) learners from secondary schools in Mpumalanga completed a science and mathematics questionnaire. Student's t tests showed that male and female, as well as language groups' scores, differed significantly.…

This paper reports on the process of modifying the ModelCreator item generation system to produce output in multiple languages. In particular, Japanese and Spanish are now supported in addition to English. The addition of multilingual functionality was considerably facilitated by the general formulation of our natural language generation system,…

This report builds on and extends existent research on population invariance to new tests and issues. The authors lay the foundation for a deeper understanding of the use of population invariance measures in a wide variety of practical contexts. The invariance of linear, equipercentile and IRT equating methods are examined using data from five…
