Variation is a key concept in the study of statistics and its understanding is a crucial aspect of most statistically related tasks. This study aimed to extend and apply a hierarchy for describing students' understanding of variation that was developed in a sampling context to the context of a natural event in which variation occurs. Students aged…

The purpose of this series of case studies was to compare the impact of Constant Time Delay and Strategic Instruction on the maintenance and generalization of learning. Four middle school students with learning disabilities were effectively taught two different groups of multiplication facts using Constant Time Delay and Strategic instruction. The…

The purpose of this study was to investigate the effects of using problem-solving strategies in middle school mathematics classes. Participants were seventh grade Pre-algebra students from a school located in Maryland. Sixty-nine students participated in the study. Using math attitudinal surveys, exit tickets, observations and interviews as…

In this paper, I will discuss two related activities that I have developed for use in a college geometry course directed at pre-service secondary and elementary school teachers. These activities ask students to develop geometry on pool tables and on cones. The two activities are closely related, and both ask students to relate computer models with…

A survey of Georgia O'Keeffe Middle School math classes five years ago would have revealed ability-grouped classes, with lower level classes populated by poor, minority students; an eclectic curriculum based upon teacher-selected content and pedagogy; and a significant percentage of students scoring less than proficient on state standardized…

The major purpose of this study was to attempt to understand some of the reasons for Mathematics perception of Taiwanese children compared to American children. The study was conducted with elementary schools in the Denver metropolitan area and Taipei, Taiwan in which fifth graders in each city (21 and 37 respectively) were selected as target…

The purpose of this study was to explore the effectiveness of using ALEKS (Assessment and Learning in Knowledge Spaces [3]), an online interactive learning system, in teaching a college algebra course at a university. This system was used to replace traditional assignments. The study was conducted in eight college algebra courses in the Fall 2003…

Some of our most challenging youth are educated in interim, short-, and long-term alternative school settings. Many of those youth have emotional disturbances and learning disabilities and have experienced academic and social failure in other school settings. Federal mandates require teachers to provide mathematics instruction to those students…

Although sampling has been mentioned as part of the chance and data component of the mathematics curriculum since about 1990, little research attention has been aimed specifically at school students' understanding of this descriptive area. This study considers the initial understanding of bias in sampling by 639 students in grades 3, 5, 7, and 9.…

This article attempts to extend current research and development activities related to the use of technology in problem posing, to early grades mathematics. It is motivated by the authors' work with elementary preservice teachers toward this goal, both at the graduate and undergraduate levels. New York State Learning Standards for K-4 mathematics…

The Science and Mathematics Alliance for Recruiting and Retaining Teachers (SMARRT) is a collaborative partnership pursuing aggressive strategies to recruit high quality minority teachers to teach in high-need schools in urban school districts. This partnership is dedicated to recruiting, preparing, and retaining high quality teachers with strong…

Frequently writing is now no longer the central mode of representation in learning materials--textbooks, Web-based resources, teacher-produced materials. Still (as well as moving) images are increasingly prominent as carriers of meaning. Uses and forms of writing have undergone profound changes over the last decades, which calls for a social,…

The 2009 edition of the "State Teacher Policy Yearbook" is the National Council on Teacher Quality's (NCTQ's) third annual review of state laws, rules and regulations that govern the teaching profession. This year's report is a comprehensive analysis of the full range of each state's teacher policies, measured against a realistic…

The Idaho edition of the National Council on Teacher Quality's (NCTQ's) 2009 "State Teacher Policy Yearbook" is the third annual look at state policies impacting the teaching profession. It is hoped that this report will help focus attention on areas where state policymakers can make changes that will have a positive impact on teacher…

This report presents findings about teacher quality from two longitudinal studies, the National Longitudinal Study of "No Child Left Behind" (NLS-"NCLB"), and the Study of State Implementation of Accountability and Teacher Quality Under "No Child Left Behind" (SSI-"NCLB"). The research teams for these two…
