The purpose of the study is to analyze the affective traits that affect mathematics achievement through Structural Equation Modeling (SEM) as a traditional regression model and Multivariate Adaptive Regression Splines (MARS), as one of the data mining methods. Structural Equation Modeling, one of the regression-based methods, is quite popular for…

We report results from two studies on the underlying dimensions of morphological awareness and vocabulary knowledge in elementary-aged children. In Study 1, 99 fourth-grade students were given multiple measures of morphological awareness and vocabulary. A single factor accounted for individual differences in all morphology and vocabulary…

Our purpose was to examine different approaches to modeling the time-varying nature of exceptionality classification. Using longitudinal data from one state's mathematics achievement test for 28,829 students in Grades 3 to 8, we describe the reclassification rate within special education and between general and special education, and compare four…

Learning to write in middle school requires the expansion of sentence-level and discourse-level language skills. In this study, we investigated later language development in the writing of a cross-sectional sample of 235 upper elementary and middle school students (grades 4-8) by examining the use of (1) lexico-grammatical forms that support…

Extensive support for the seemingly paradoxical negative effects of school- and class-average achievement on academic self-concept (ASC)-the big-fish-little-pond effect (BFLPE)--is based largely on secondary students in Western countries or on cross-cultural Program for International Student Assessment studies. There is little research testing the…

Large-scale studies, such as the Trends in International Mathematics and Science Study (TIMSS), provide data to understand cross-national differences and similarities. In this study, we aimed to identify factors predicting mathematics achievement of Turkish students by comparing to Australian students. First, construct equivalence and item bias…

This study aimed to examine whether the relationships among family resources, school climate, learning participation, science attitude, and science achievement are different between primary school students and junior high school students within one educational system. The subjects included 4,181 Grade 4 students and 5,074 Grade 8 students who…

Educational reform initiatives of the last decade have focused on the three R's: reading, writing, and arithmetic, with writing receiving the least attention in the research literature (National Commission on Writing, 2003). Studies of writing performance in United States schoolchildren indicate that many are writing only at basic levels. The…

This research investigates the relative importance of vocabulary and oral reading fluency as measurement dimensions of reading comprehension as the student passes from elementary to high school. Invariance of this model over grades 4 through 8 is tested using two independent student samples reading grade-level appropriate passages. Results from…

This study examined the hypothesized relationship between social adjustment, as measured by perceived social support, self-concept, and social skills, and performance on academic achievement tests. Participants included 27 teachers and 77 fourth- and eighth-grade students with diverse academic and behavior competencies. Teachers were asked to…

The Simple View of Reading states that reading comprehension is the product of word recognition and listening comprehension. Whereas much research has focused on word recognition accuracy, recent attention has been directed toward word recognition fluency. The current study investigated whether a separate fluency component should be added to the…
