The purpose of this study was to explore the relationship of gender between actual and preferred classroom environment and use of technology in the science classroom of Turkish students. Employing stratified random sampling procedures, data were collected from 985 students from schools across twelve different districts in Istanbul, Turkey. The…

Most of the tests and inventories used by counseling psychologists have been developed using CTT; IRT derives from what is called latent trait theory. A number of important differences exist between CTT- versus IRT-based approaches to both test development and evaluation, as well as the process of scoring the response profiles of individual…

There is considerable research on the difficulties students have in conceptualising individual concepts of probability and statistics (see for example, Bryant & Nunes, 2012; Jones, 2005). The unit of work developed for the action research project described in this article is specifically designed to address some of these in order to help…

The aim of this work is to develop and investigate the model for assessing learning management on the enrichment science classrooms in the upper secondary education of the Development and Promotion of Science and Technology Talents Project in Thailand. Using the research methodologies with the four phases: to investigate the background of the…

Despite the widespread popularity of growth curve analysis, few studies have investigated robust growth curve models. In this article, the "t" distribution is applied to model heavy-tailed data and contaminated normal data with outliers for growth curve analysis. The derived robust growth curve models are estimated through Bayesian…

Computer-based multimedia presentations employing animated agents (avatars) can positively impact perceptions about engineering; the current research advances our understanding of this effect to pre-college populations, the main target for engineering outreach. The study examines the effectiveness of a brief computer-based intervention with…

A robust body of research has identified associations between positive teacher-child relationships--characterized by high levels of closeness and low levels of conflict--and children's academic achievement in elementary school (e.g. Roorda, 2012). Additional studies find that high-quality teacher-child relationships may promote academic resilience…

This report presents the number of high school completers, the Averaged Freshman Graduation Rate (AFGR), and the dropout data for grades 9-12 for public schools in school year 2009-10. State Education Agencies (SEAs) report annual counts of completers, dropouts, and enrollments to the National Center for Education Statistics' (NCES) Common Core of…

The authors intended to (a) identify the association between gender or grade level and teachers' homework (HW) feedback and (b) examine the relationship between teachers' HW feedback, HW-related behaviors (e.g., amount of HW completed), and academic achievement. Four hundred fifty-four students (Grades 5-12) participated in this study. The results…

The focus of this study was on increasing the knowledge base on students with disabilities at the secondary level. Data were gathered on 559 classified secondary students with disabilities served in four educational options: cotaught classes, resource rooms, alternate day support programs, and no direct supports. Results indicate that there are…

This document reports data from the 2015 School Crime Supplement (SCS) to the National Crime Victimization Survey (NCVS). The Web Tables show the extent to which students with different personal characteristics report being bullied. Estimates include responses by student characteristics: student sex, race/ethnicity, grade, and household income.…

A general diagnostic model was used to specify and compare two multidimensional item-response-theory (MIRT) models for longitudinal data: (a) a model that handles repeated measurements as multiple, correlated variables over time (Andersen, 1985) and (b) a model that assumes one common variable over time and additional orthogonal variables that…
