A set procedure developed in this study is useful in determining sample size, based on specification of linear contrasts involving certain formula treatments. (Author/DEP)

This paper presents an overview of the design features that were developed for the Content Analysis Project. The purpose of the project was to examine the congruence between a state's test in eighth-grade mathematics and that used by the National Assessment of Educational Progress. The results of this analysis were then to be used to determine…

Different methodologies for linking tests across languages are reviewed and evaluated, focusing on monolingual item response theory, bilingual group designs, and matched monolingual group designs. These methods, although not without weaknesses, are superior for promoting score comparability than methods that rely on translation or expert judgment…

A context in which existing items may provide a convenient source of questions for questionnaires was explored through a case study making use of existing comparison groups. Two programs at Oak Ridge Associated Universities (ORAU), the Science and Engineering Research Semester (SERS) and the Laboratory Graduate Research Participation (Lab Grad)…

A survey of compensatory and noncompensatory reading programs in grades 2, 4, and 6 of the U. S. public schools was carried out in spring 1972. Phase I, the subject of this report, involved two tasks: (1) describing what was meant by "compensatory reading", and (2) identifying the characteristics of schools in which compensatory reading…

This paper addresses two audiences--those who design education trend studies that simultaneously have longitudinal and intercohort implications, and the secondary analysts who use such trend data. Four study series conducted for the U.S. Department of Education's National Center for Education Statistics (NCES) provide material for the paper: the…

The Third International Mathematics and Science Study (TIMSS) developed and administered tests and questionnaires in three student populations to document the quality of mathematics and science education in 45 participating countries. Study design, instrument development, and research procedures were achieved through a complex collaborative…
