By measuring students' attitudes towards science using Rasch modelling, the present study investigated the factors related to elementary students' attitudes toward science at both the individual- and school- levels using HLM in China, where students are often reported to have high achievement in science with below-average attitudes towards the…

The purpose of this quantitative correlational study was to examine if and to what extent, Title I Status, the Number of Years teachers have taught at the current school, and/or the Level of Teacher Education predict the Teacher Perception of Distributed Leadership in central Florida public elementary schools. Research focused on the theoretical…

In this study, we explored teachers' attention to and flexibility with referent units as well as how teachers' understanding of referent units is related to their performance on other fraction concepts and their professional background. By using data collected from 246 U.S. mathematics teachers in Grades 3-7 where fractions are taught, we found…

This non-experimental, quantitative study explored how factors related to teachers' beliefs, curricular orientation, training and support received, and their identity and background experiences are associated with their use of curriculum. Specifically, this study sought to examine teachers' use of a curricular resource specifically designed to…

This paper describes the ideas that mathematics teachers (grades 5-9) have regarding mathematical models of real-world phenomena, and explores how teachers' ideas differ depending on their educational background. Participants were 56 United States in-service mathematics teachers. We analyzed teachers' written responses to three open-ended…

Background: Educational outcomes for language minority (LM) children are of great concern across the nation because these students have lower grades, are rated by their teachers as having lower skills, perform worse on standardized tests, and are more likely to drop out than are non-LM students. Given this context of underperformance, there is a…

This article begins to unravel the question, "What curricular materials work best under what kinds of conditions?" The authors address this question from the point of view of teachers and their ability to implement mathematics curricula that place varying demands and provide varying levels of support for their learning. Specifically, the…
