Traditionally, women and minorities have not been fully represented in science and engineering. Numerous studies have attributed these differences to gaps in science achievement as measured by various standardized tests. Rather than describe mean group differences in science achievement across multiple cultures, this study focused on an in-depth…

In conjunction with the adoption and subsequent implementation of the "Common Core State Standards for Mathematics" (CCSSM), state-led consortia are developing next-generation assessments aligned to the CCSSM. This paper discusses the progress and plans of two main coalitions of states--the Partnership for Assessment of Readiness for…

This study followed the comparative research mode of description, interpretation, juxtaposition and comparison. Based on the literatures and data collected on the topic, the paper compared and analyzed the past, present and future of APTHS (academic proficiency test for high schools) in the two countries. Some contemplations on the common issues…

Many efforts have been made to determine and explain differential gender performance on large-scale mathematics assessments. A well-agreed-on conclusion is that gender differences are contextualized and vary across math domains. This study investigated the pattern of gender differences by item domain (e.g., Space and Shape, Quantity) and item type…

Background: Strand, Deary, and Smith (2006) reported an analysis of sex differences on the Cognitive Abilities Test (CAT) for over 320,000 UK students 11-12 years old. Although mean differences were small, males were overrepresented at the upper and lower extremes of the score distributions on the quantitative and non-verbal batteries and at the…

The purpose of this document is to provide background information that will be useful in interpreting the 2007 results from the Trends in International Mathematics and Science Study (TIMSS) by comparing its design, features, framework, and items with those of the U.S. National Assessment of Educational Progress and another international assessment…

Two structural laws for intelligence tests are discussed: one law concerns the sign of correlation coefficients and gives conditions under which all correlations between test items will be positive; and one law concerns the relative sizes of the correlation coefficients between intelligence items. A cylindrical structure extends these laws. (SLD)

The idea that validity should be considered a property of inferences, rather than of assessments, has developed slowly over the past century. In early writings about the validity of educational assessments, validity was defined as a property of an assessment. The most common definition was that an assessment was valid to the extent that it…
