Background: Both ability (measured by power tests) and non-ability (measured by preference tests) individual difference measures predict academic school outcomes. These include fluid as well as crystalized intelligence, personality traits, and learning styles. This paper examines the incremental validity of five psychometric tests and the sex and…

This study explored the relationship between reading and achievement on a science standardized test. A nonfiction reading subtest and the science section of the Connecticut Academic Performance Test were compared for Grade 10 students at 3 Connecticut high schools. Results showed a moderate-to-strong positive relationship between the variables.…

Several studies provide preliminary evidence that computer use is positively related to academic performance; however, no clear relationship has yet been established. Using a national database, we analyzed how students' school behavior (i.e., evaluated by English and math teachers) and standardized test scores (e.g., math and reading) are related…

This report reviews Advanced Placement (AP) and International Baccalaureate (IB) examination participation and performance in Texas during the 2009-10 school year. Campus-, district-, and state-level examination results for students in Texas public schools are presented, as well as state-level examination results for students in Texas public and…

This study describes limited English proficient (LEP) student enrollment and achievement trends in Maryland. Two research questions guide this study: (1) How did the enrollment of LEP students in Maryland public schools change between 2002/03 and 2008/09?; and (2) How did performance (the percentage scoring at the proficient or advanced level) on…

This study describes English language learner (ELL) student enrollment trends between 2002/03 and 2008/09 and achievement trends between 2006/07 and 2008/09 in the District of Columbia. Two research questions guide this study: (1) How did the enrollment of ELL students in District of Columbia public schools change between 2002/03 and 2008/09?; and…

Purpose. The purpose of this study was to determine if there was a significant difference in academic achievement on the California Standards Tests (CSTs) in English and mathematics of students enrolled in the California Partnership Academy compared to the nonacademy population. A second purpose was to analyze the percentage of first-time passage…

What is the impact of natural disasters on students' statewide assessment scores? To answer this question, Florida Comprehensive Assessment Test (FCAT) scores of 55,881 students in grades 4 through 10 were analyzed to determine if there were significant decreases after the 2004 hurricanes. Results reveal that there was statistical but no practical…

Astronomy was a required subject in the first American secondary level schools, the academies of the 18th century. When these were supplanted a century later by public high schools, astronomy still was often required, subsumed into courses of Natural Philosophy. Reasons given at that time to support astronomy as a part of general education include…

The objective of the present investigation was to compare the adequacy of two cognitive models for predicting examinee performance on a sample of algebra I and II items from the March 2005 administration of the SAT[TM]. The two models included one generated from verbal reports provided by 21 examinees as they solved the SAT[TM] items, and the…

The current study investigated the gender differences of gifted adolescents' math/verbal self-concept and math/verbal ability by examining the Internal/External Frame of Reference Model (I/E model; Marsh, 1986). The sample consisted of 181 gifted adolescents, ranging in age from 12 to 16 years old. Gifted adolescents' math/verbal ability was…

This Research Brief presents a method for predicting 10th grade Florida Comprehensive Assessment Test (FCAT) success from 6th grade FCAT performance. A simple equation provides the most probable single score prediction, and give-or-take error margins define high and low probability zones for expected 10th grade scores. In addition, a double-entry…

Despite academic progress, standardized tests have been a handicap in school's quest to meet the yardstick for adequate yearly progress (AYP) under the federal No Child Left Behind Act. The law requires that students be tested annually in reading and math in grades 3-8 and once during high school. Schools must show sufficient gains in performance…

This article explores the reasoning employed by high school students to answer a set of multiple-choice history questions. The questions come from New York State's Global History and Geography Regents exam. The Regents exams, together with a particularly well-regarded and ambitious set of content standards, are the cornerstone of the state's…

This article illustrates the use of an explanatory item response modeling (EIRM) approach in the context of measuring group differences in science achievement. The distinction between item response models and EIRMs, recently elaborated by De Boeck and Wilson (2004), is presented within the statistical framework of generalized linear mixed models.…
