Karabatsos and Walker (2011) introduced a new Bayesian nonparametric (BNP) regression model. Through analyses of real and simulated data, they showed that the BNP regression model outperforms other parametric and nonparametric regression models of common use, in terms of predictive accuracy of the outcome (dependent) variable. The other,…

The present study examines data collected during the second year of a three-year longitudinal cluster randomized controlled trial, the Responsive Classroom Efficacy Study (RCES). In the context of and RCT, the research questions address naturally occurring variability in the independent variables of interest (i.e., teachers' (fidelity of…

This study focused on gender-based mathematics performance. It was a qualitative study of girls and their mothers conducted to identify variables that may to be associated with the success or lack of success of the girls. By examining maternal responses to mathematics-related questions, themes emerged that could be related to information gathered…

Student achievement is not progressing on mathematics as measured by state, national, and international assessments. Much of the research points to mathematics curriculum and instruction as the root cause of student failure to achieve at levels comparable to other nations. Since mathematics is regarded as a gate keeper to many educational…

This report presents findings from a randomized control trial designed to inform the decisions of policymakers who are considering using online courses to provide access to Algebra I in grade 8. It focuses on students judged by their schools to be ready to take Algebra I in grade 8 but who attend schools that do not offer the course. The study…

Competent mathematical skills are needed in the workplace as well as in the college setting. Adults in Adult Basic Education classes and programs generally perform below high school level competency, but very few studies have been performed investigating the predictors of mathematical success for adults. The current study contributes to the…

The staff of the Center for Evaluation & Education Policy (CEEP) at Indiana University is often asked about how international large-scale assessments influence U.S. educational policy. This policy brief is designed to provide answers to some of the most frequently asked questions encountered by CEEP researchers concerning the three most popular…

This innovation configuration offers a set of quantifiable indicators of instructional excellence in mathematics. These indicators are related to improved achievement in mathematics and can be used to improve teacher competencies. The innovation configuration is offered as a means of evaluating and aligning teacher preparation and professional…

This report, the third of three reports examining Supplemental Education Services (SES) within the Wake County Public School System (WCPSS), focused on the long-term goal of improved student achievement by the end of the school year. In 2009-10, 508 students participated in SES at the five schools offering SES: Brentwood, Fox Road, Poe, Wendell,…

The goal of the present study was to report an instrument designed to determine students' mathematical performances and preference for visual or analytic thinking for the calculus derivative and antiderivative tasks as well as examine the relationships among students' cognitive style, cognitive ability, and mathematical performance in calculus.…

This report describes the results of analyses comparing novice (teachers with 1-3 years of teaching experience) alternatively certified teachers with novice teachers who were traditionally certified, examining trends in student state test performance.

Males have significantly higher average scores than females on the SAT I quantitative section, which is designed to predict first-year college success in mathematics. However, it has been shown that gender gaps in performance on the SAT I have little to do with college readiness; rather they are due to the misaligned content of the instrument, as…

In recent years, a consensus has emerged among researchers that teacher quality matters enormously for student performance. Students taught by more-effective teachers learn substantially more over the course of the year than students taught by less-effective teachers. Yet little is known about what makes for a more-effective teacher. Most research…

This causal-comparative study evaluated a 30-week chess instructional program implemented within special education math classes for students in the sixth, seventh, and eighth grades in a suburban middle school located in the southwestern United States. An analysis of covariance (ANCOVA) was utilized to compare the adjusted means for the comparison…

In this article we analyzed the literature regarding charter schools in the State of Texas. We specifically examined the evolution of the charter school movement in Texas. Moreover, data regarding the effectiveness/ineffectiveness of charter schools in Texas were discussed. Our overview of Texas charter schools, given their widespread presence in…
