Research has shown that a profound place value understanding is crucial for success in learning mathematics. At the same time, a substantial number of students struggles with developing a sustainable place value understanding. In this regard, two aspects of the place value system appear especially relevant: First, the knowledge of the decimal…

Several studies have tested the validity of the simple view of reading model by examining various degrees of orthographic depth. This study aims to validate this model in both transparent and deep versions of Arabic. In addition, the contribution of the basic components of decoding and listening comprehension to reading comprehension in the…

This study examined the dynamic relationships among the components of the Simple View of Reading (SVR) in a transparent orthography (Finnish) and the predictive value of cognitive skills (phonological awareness, letter knowledge, rapid naming, and vocabulary) on the SVR components. Altogether, 1,815 Finnish children were followed from kindergarten…

The development of scientific thinking was assessed in 1,581 second, third, and fourth graders (8-, 9-, 10-year-olds) based on a conceptual model that posits developmental progression from naïve to more advanced conceptions. Using a 66-item scale, five components of scientific thinking were addressed, including experimental design, data…

Often, the classification of words does not go beyond "difficult" (i.e., infrequent, late-learned, nonimageable, etc.) or "easy" (i.e., frequent, early-learned, imageable, etc.) words. In the present study, we used a latent cluster analysis to divide 703 Dutch words with scores for eight word properties into seven clusters of words. Each cluster…

The Massachusetts Department of Elementary and Secondary Education (Department) created the grades 1-12 Early Warning Indicator System (EWIS) in response to district interest in the Early Warning Indicator Index (EWII) that the Department previously created for rising grade 9 students. Districts shared that the EWII data were helpful, but also…

The effects of a secondary academic intervention, embedded in the context of a positive behavior support model, on the writing of second-grade students at risk for emotional and behavioral disorder and writing problems were examined in this study. Students were taught how to plan and draft a story using the self-regulated strategy development…

Poor performance on tests of reading comprehension could be the result of weak word-recognition skills, inconsistent attention (ADD), or a combination of the two. Identifying the source of the reading disability (RD) reliably has been difficult because inconsistent attention interferes with reading and weak word recognition skill makes attention…

Using a mixed-methodology, longitudinal design, individual differences and contextual factors related to differential response to general education instruction were examined. We tested a response-to-instruction model reflecting the first three phases of a model proposed by Fuchs and Fuchs (1998). We classified first- and second-grade children…
