The purpose of this quantitative correlational study was to investigate relationships between grade levels, personal factors of teachers, and instructional variety used by 4th-12th grade teachers in Kern County, California. The population under investigation included 2,844 teachers. 235 elementary, middle school/junior high, and secondary teachers…

This paper presents some of the major issues raised in Education International's preliminary analysis of the overall PISA (Programme for International Student Assessment) 2009 study. Some of these issues are: (1) PISA has serious limitations. The study does not cover the full curriculum, focusing on a narrow set of subject areas, neglecting such…

In this article the authors analyze the effect of private voucher education on student academic performance using new data on Chilean students and a novel identification strategy. Most schools in Chile provide either primary or secondary education. The authors analyze the effect of private voucher education on students who are forced to enroll at…

Few researchers have addressed student achievement outcomes as a function of grade configurations for older elementary-aged students. Thus, this study was designed to determine differences between students' Grade 5 reading and mathematics achievement in elementary schools (K-5) as compared to intermediate schools (Grade 5, 5-6) for 5 academic…

The "WVEB" Mathematics Project is a collaborative program offering college-level courses to high school students. Results of a matched-pair study comparing on- and off-campus students in algebra indicate that both sections show a significant gain in score on the math "ACT" test, with no difference in gain found between…

Despite concerted efforts by science educators to understand patterns of evolutionary reasoning in science students and teachers, the vast majority of evolution education studies have failed to carefully consider or control for item feature effects in knowledge measurement. Our study explores whether robust contextualization patterns emerge within…

The most critical feature of a common-item nonequivalent groups equating design is that the average score difference between the new and old groups can be accurately decomposed into a group ability difference and a form difficulty difference. Two widely used observed-score linear equating methods, the Tucker and the Levine observed-score methods,…

Much of the debate surrounding school choice in general and charter schools in particular revolves around the types of students who choose to leave their traditional public schools in favor of enrolling in charter schools and the possible effects of these choices on the schools that they leave behind (Dee & Fu, 2004; Henig, 1994; Schneider,…

Hippotherapy (HPOT) is a therapy that uses horse movement. This pilot investigation objectively evaluated the efficacy of HPOT in improving head/trunk stability in children with cerebral palsy (CP). The participants were six children with spastic diplegia and six children without disability. Head and trunk stability was challenged by using a…

There is a growing body of research literature that considers how the mode of assessment, either computer-based or paper-based, might affect candidates' performances. Despite this, there is a fairly narrow literature that shifts the focus of attention to those making assessment judgements and which considers issues of assessor consistency when…

Surveys were administered to adolescents (N = 144) to determine if young people varied based on the type of long-term aims they held. Using cluster analysis, four groups emerged from the data: youth without clear long-term aims, youth with self-oriented long-term aims, youth with other-oriented long-term aims, and youth with both self- and…

This study examined the association between female sexual offending behavioral patterns, as delineated by Sandler and Freeman's (2007) typologies, and executive functioning. The sample included all referrals for sexual offender assessments within a women's maximum/medium security prison between January 2009 and October 2009. Each subject was…

The authors examined whether paper-and-pencil and Web surveys administered in the school setting yield equivalent risk behavior prevalence estimates. Data were from a methods study conducted by the Centers for Disease Control and Prevention (CDC) in spring 2008. Intact classes of 9th- or 10th-grade students were assigned randomly to complete a…

The Lothian Birth Cohort 1936 sample is in a uniquely good position to provide relevant data on social class mobility patterns over most of the last century. These participants, with known ultimate social class attainment, took a validated mental test in the Scottish Mental Survey of 1947 and were followed up at approximately age 70. Then, besides…

This paper compares three methods of item calibration--concurrent calibration, separate calibration with linking, and fixed item parameter calibration--that are frequently used for linking item parameters to a base scale. Concurrent and separate calibrations were implemented using BILOG-MG. The Stocking and Lord (1983) characteristic curve method…
