In this longitudinal study, we investigated the role of word reading and mathematical difficulties measured in 9th grade as factors for receiving educational support for learning in upper secondary education in Grades 10 to 12 (from ages 16 to 19) and furthermore as predictors of dropout from upper secondary education within 5 years after…

This study investigated the role of strategy instruction and working memory capacity (WMC) on word problem solving accuracy in children with (n = 100) and without (n = 92) math difficulties (MD). Within classrooms, children in Grades 2 and 3 were randomly assigned to one of four treatment conditions: verbal-only strategies (e.g., underlining…

The need to address social and economic changes has focused greater attention on our public education system and the need to better equip students with the skills needed for a global society. This quantitative study was grounded in the principles of the constructivist learning theory. The purpose of this study was to determine whether the added…

Usually, methods for detection of differential item functioning (DIF) compare the functioning of items across manifest groups. However, the manifest groups with respect to which the items function differentially may not necessarily coincide with the true source of the bias. It is expected that DIF detection under a model that includes a latent DIF…

Background: "Hurricane Katrina" devastated the Mississippi Gulf Coast in August 2005. Intrusive re-experiencing is a common posttraumatic stress symptom. However, young children with limited introspection skills might have difficulties identifying their intrusive thoughts. Method: A sample of 165 5- to 9-year-old children were surveyed about their…

Introductory business classes, particularly those with a quantitative emphasis, can often serve as a barrier to students rather than as a gateway. This study looks at how study skills, aptitude, and external factors affect classroom performance. We examine whether, when, how, and how much students read their textbook. We also look at selected deep…

The teaching brain is a dynamic system that is in constant interaction with the learning brain. If we fail to explore the teaching brain we will continue to design educational reform policies that ignore the most important lens in the classroom: the teachers'. Master teachers recognize their perspective and leverage their teaching brains to embody…

This dissertation tests a dynamic assessment-based cognitive hierarchy model and attempts to identify mathematical concepts that predict student learning potential on more advanced mathematical concepts using the units from ST Math, a self-paced curriculum, for third, fourth, and fifth grade students. The quantitative analyses compared a…

Fifteen elementary and secondary teacher candidates solved sixteen integer addition and subtraction problems during think-aloud interviews. Investigators further probed participants' solution strategies as well as what they noticed first when starting a new problem. Task analyses of participants' solutions led to the creation of two distinct maps…

According to the Texas Education Code §29.121 and the Houston Independent School District (HISD) Board Policy, Gifted and Talented (G/T) students are "those identified by professionally qualified persons, who perform at, or show the potential for performing at a remarkably high level of accomplishment when compared to others of the same age,…

The central question in this study is whether the language and math delays of the different socio-economic and ethnic minority groups targeted by Dutch educational disadvantage policy have diminished or not. Data are from the years 1995, 1999, 2003 and 2008. Information from a total of 90,000 pupils in Grades 2 and 8 was selected to represent the…

This study was undertaken with an aim to understand whether the effective use of the blackboard, one of the teaching aids utilized by Anadolu University's distance learning program in the e-television Open Classroom, has a positive effect on focus and concentration. Gagne's Theory of Instruction was utilized during this research. Knowledge of the…

The effect of two training procedures on the development of reading speed in poor readers is examined. One training concentrates on the words the children read correctly ("successes"), the other on the words they read incorrectly ("failures"). Children were either informed or not informed about the training focus. A randomized controlled trial was…

This study investigates the relationship between salaries and scholastic aptitude for full-time public high school humanities and mathematics/sciences teachers. For identification, we rely on variation in salaries between adjacent school districts within the same state. The results indicate that teacher aptitude is positively correlated with…

Statements conveying a degree of certainty or doubt, in the form of hedging, have been linked with logical inference in students' talk (Rowland, 2000). Considering the current emphasis on increasing student autonomy for effective mathematical discourse, I posit a relationship between hedging and student autonomy. In the current study, high school…
