easyCBM[R] is an online benchmark and progress monitoring assessment system designed for use within a response to intervention framework. Educators using easyCBM[R] are often interested in using the results to predict students' state test performance. In the following technical document, we report diagnostic efficiency statistics using a sample…

To investigate the structure of number sense and then to assess its uses in fifth-grade children's number sense development, a computerized number sense scale was developed and evaluated. The findings of the study indicate that the newly developed scale, with four dominant factors identified and reconfirmed, is internally consistent and…

This study examined the feasibility of administering GED Tests using a computer based testing system with embedded accessibility tools and the impact on test scores and test-taker experience when GED Tests are transitioned from paper to computer. Nineteen test centers across five states successfully installed the computer based testing program,…

The purposes of the present study were (a) to compare US and Korean 8th graders' mastery of knowledge and skills in the mathematics test of the Trends in International Mathematics and Science Study (TIMSS) 2003 using a cognitive diagnostic testing method and (b) to find links between teachers' instruction and students' mastery of mathematics…

The association between grade retention in first grade and passing the third grade state accountability tests, the Texas Assessment of Knowledge and Skills (TAKS) reading and math, was investigated in a sample of 769 students who were recruited into the study when they were in first grade. Of these 769 students, 165 were retained in first grade…

To date, assessment validity research on non-native English speaking students in the United States has focused exclusively on those who are presently English language learners (ELLs). However, little, if any, research has been conducted on two other sizable groups of language minority students: (a) bilingual or multilingual students who were…

The Maui Hawaii Educational consortium sought evidence for the effectiveness of the "Cognitive Tutor[R] (CT) program, published by Carnegie Learning, to help inform adoption decisions. The question being addressed specifically by the research in both years of previous studies was whether students in classes that use "CT" materials…

Background: "Thinking aloud" is a well-established method of data collection in education, assessment, and other fields of research. However, while many researchers have reported their views on its usage, the first-hand experiences of research participants have received less attention. Purpose: The aim of this exploratory study was to…

This article examines the complex task of designing a large-scale assessment to align with a reform-oriented view of mathematics teaching and learning. Specifically, we address this issue through the case of the province of Ontario that has a reform-oriented curriculum and support for its implementation. The province also has a mandate to assess…

The "Second Annual National Survey on Assessments and Accommodations for Students who are Deaf or Hard of Hearing" investigated the types of testing accommodations used on 2004-2005 statewide standardized assessments as well as recommendations for best practices. A total of 444 participants who served over 9,000 students as teachers,…

Students with learning disabilities are increasingly included in state accountability systems. The purpose of this study was to investigate disability-based differential item functioning (DIF) on a statewide high-stakes mathematics test administered in the Spring of 2003 to all students seeking a high-school diploma in one state in the eastern…

A general diagnostic model was used to specify and compare two multidimensional item-response-theory (MIRT) models for longitudinal data: (a) a model that handles repeated measurements as multiple, correlated variables over time (Andersen, 1985) and (b) a model that assumes one common variable over time and additional orthogonal variables that…

In this report, an alternative item response theory (IRT) observed score equating method was newly developed. The proposed equating method was illustrated with two real data sets and the equating results were compared to those of traditional IRT true score and IRT observed score equating methods. Using three loss indices, the new method appeared…

Although research has extensively documented sources for differential item functioning and stereotype threat--especially among women and black college students--little is known about group differences in test-taking strategies among black adolescent students. In this article, Arbuthnot presents findings from two studies that seek to explore how…

The purpose of this randomized experiment was to compare the performance of high-, average-, and low-achieving middle school students who were assessed with parallel versions of a computer-based test (CBT) or a paper-pencil test (PPT). Tests delivered in interactive, immersive environments like the CBT may have the advantage of providing teachers…
