The study examined the effect of charter school attendance on annual student achievement growth in math and reading. The study analyzed data from a large sample of students in grades three through eight in New York City between 2003 and 2009. The authors matched charter school students to similar students attending traditional public schools based…

The current study identified socioeconomic status (SES) group differences in student performance on an eighth grade mathematics assessment derived from the Third/Trends in International Mathematics and Science Study (TIMSS) 2003. Differential item functioning (DIF) methodology was applied to examine SES group differences on item performance for…

To ensure fairness, it is important to better understand the relationship of language proficiency with the standard procedures of psychometric analysis. This paper examines how equating results are affected by an increase in the proportion of examinees who report that English is not their first language, using the analysis samples for a…

This paper presents an application of a stochastic approximation EM-algorithm using a Metropolis-Hastings sampler to estimate the parameters of an item response latent regression model. Latent regression models are extensions of item response theory (IRT) to a 2-level latent variable model in which covariates serve as predictors of the…

Language skills are becoming an increasingly important feature of performance in mathematics classrooms. This new focus on language highlights the need to identify math vocabulary words and to apply research-based principles for vocabulary instruction in mathematics lessons. This article offers one way to analyze state high-stakes math tests to…

The underrepresentation of women at the top of math-intensive fields is controversial, with competing claims of biological and sociocultural causation. The authors develop a framework to delineate possible causal pathways and evaluate evidence for each. Biological evidence is contradictory and inconclusive. Although cross-cultural and cross-cohort…

Person-fit is a statistical index that can be used as a direct measure of assessment accuracy by analysing response patterns and identifying individuals with aberrant or unusual responses with respect to a testing model. For these individuals test scores may be an inaccurate measure of their true ability. To comprehend person-fit and its…

This article reports on a study carried out to measure the mathematical literacy of a selection of students entering third-level education in Ireland. The study investigates how such students performed when confronted with mathematical tasks, which, though commensurate with their level of education, may not have been familiar to them, and to…

We investigate the conceptual and procedural knowledge in integration of a group of students who has successfully completed a one-year calculus course. The participants are asked five questions and their responses are analysed in detail. We observed that the students do not have satisfactory conceptual understanding of integration. Moreover, it is…

This article reports on an innovative approach to teaching Calculus I which was initiated in a two-semester course designed for students at risk of failing Calculus I. The treatment consisted of voluntary oral assessments offered before every written examination. Analyses showed that the treatment students did significantly better than the control…

This paper examines changes in demographic and socioeconomic inequalities in student achievement over the school career, and the extent that these inequalities are accounted for by other influences such as, region and socioeconomic background (where appropriate), school differences and prior achievement. The data analysed are from a longitudinal…

The Cultural Heritage Bilingual Program (CHBP) was developed for English Language Learner (ELL) students from language groups not served by current bilingual programs in the Houston Independent School District (HISD), which are designed for Spanish-speaking ELLs. The largest group of students in this category consists of ELLs whose home language…

This study explored the performance of 75 seventh-grade students with and without disabilities, educated in inclusive mathematics classes, on open-ended, problem-solving mathematics assessments. In the study, approximately half of the students used a graphing calculator on the first assessment and not on the second assessment (n = 35; 46.7%),…

Arithmetic tests for divisibility of an integer by another integer are well known. This article states and proves conditions for divisibility in binary form.

A new study has found that state requirements that students pass exit tests to graduate from high school appear to do nothing to improve achievement on federal reading and mathematics tests. The study, the results of which have been peer-reviewed and accepted for publication in the journal "Educational Policy," compared the reading and math scores…
