Participants in achievement tests or psychometric scales can be naturally divided into various sub-groups such as gender, race, social economic status, school district, etc. In order to make meaningful comparison between groups, each item in the test/scale should measure the same underlying construct for participants came from different groups.…

The present paper aims to discuss how data from international large-scale assessments (ILSAs) can be utilized and combined, even with other existing data sources, in order to monitor educational outcomes and study the effectiveness of educational systems. We consider different purposes of linking data, namely, extending outcomes measures,…

The authors review the influence of state, national and international large-scale assessments (LSAs) on education policy and research. They distinguish between two main uses of LSAs: as a means for conducting research that informs educational reform and LSAs as a tool for implementing standards and enforcing accountability. The authors discuss the…

This Forum discusses the significant growth of international large-scale assessments (ILSAs) since the mid-1990s. Addey and Sellar's contribution ("A Framework for Analysing the Multiple Rationales for Participating in International Large-Scale Assessments") outlines a framework of rationales for participating in ILSAs and examines the…

International large-scale assessments (ILSAs) play a distinct role in the United States' decentralized federal education system. Separate from national and state assessments, they offer an external, objective measure for the United States to assess student performance comparatively with other countries and over time. The US engagement in ILSAs…

This study investigated the application of multidimensional item response theory (IRT) models to validate test structure and dimensionality. Multiple content areas or domains within a single subject often exist in large-scale achievement tests. Such areas or domains may cause multidimensionality or local item dependence, which both violate the…

This study examined the effects of testing accommodations on eighth-grade students' performance on large-scale achievement tests and also on their attitudes and reactions to the tests. Findings revealed significant differences in the ways students with and without disabilities experienced testing and how testing accommodations affected students'…

Collaborative testing has been shown to improve performance but not always content retention. In this study, we investigated whether collaborative testing could improve both performance and content retention in a large, introductory biology course. Students were semirandomly divided into two groups based on their performances on exam 1. Each group…

The major purpose of this study was to determine whether science process achievement tests could be developed which could be administered to groups of primary grade pupils. Tests developed were a series of 35mm color slides which illustrated laboratory situations involving basic science processes. The slides were synchronized with a tape recording…

Achievement tests may be either norm-referenced or criterion-referenced. The norm-referenced test indicates an individual's proficiency level with respect to other individuals. A criterion-referenced test measures an individual's performance with respect to a specific level along the continuum of attainment. Further, an achievement test may be…

THE ASSUMPTION THAT ONE-TENTH OF THE YEARLY GROWTH IN ALL ACHIEVEMENT AREAS TAKES PLACE EACH MONTH OF THE SCHOOL YEAR AND THAT ONE-TENTH OF THE YEARLY GROWTH OCCURS DURING THE SUMMER MONTHS WAS INVESTIGATED. THE STUDY WAS CONDUCTED IN CONNECTION WITH THE ANNUAL IOWA BASIC SKILLS TESTING PROGRAM IN THE STATE OF IOWA. MEDIANS FOR THE 11 SUBTESTS…

Statistical procedures employed in item analysis are based on the performance of the individual on a given test. If, however, one desires to assess the efficiency of some treatment, the researcher is interested in the performance of groups of students who received the treatment rather than in the performance of any one individual. In such cases…

A GUIDE TO ASSIST PROJECT DIRECTORS IN THEIR EFFORTS TO DEVELOP INCREASINGLY MORE SYSTEMATIC AND THOROUGH EVALUATION DESIGNS FOR GREAT CITIES SCHOOL IMPROVEMENT PROGRAMS IS PRESENTED. THE TESTS, QUESTIONNAIRES, AND OTHER INSTRUMENTS AS WELL AS METHODS OF DATA TREATMENT ARE LISTED ACCORDING TO THE MAJOR EVALUATION AREAS. THREE BASIC AREAS ARE TO BE…

The investigation tested the mean overall grade level placement of senior students in Louisiana secondary schools for the 1973-74 school session to see if they could meet the same standard that was used for adult students as the prerequisite for General Educational Development (GED) testing for the high school equivalency diploma (that is a…

The three parts of Vancouver's survey test in mathematics--computation, concepts, and problems--for grade 6 are presented. The parts contain 36, 24, and 12 items respectively. (For related document, see TM 002 473.) (KM)
