Students in any grade level vary widely in their mathematics achievement, with the typical classroom including four to seven grade levels of mathematics proficiency. Due to this large range of mathematics learning needs, some schools offer certain courses in earlier grades than is typical. In this study, we analyzed multiple, large, national…

The study examined whether a professional development program for seventh grade mathematics teachers improved the teachers' knowledge of rational number topics and the performance of their students on a rational number test. Before the first year of the program, schools within districts were randomly assigned to either a treatment group that…

This research examined the effectiveness of a design-based, continuous professional development (CPD) programme intended to promote teachers' self-confidence and teaching reflection skills. The CPD was associated with teacher implementation of theoretically devised, motivational, context-based, inquiry teaching modules, based on a justified…

This is the second and final report of the Middle School Mathematics Professional Development Impact Study, which examines the impact of providing a professional development (PD) program in rational number topics to seventh-grade mathematics teachers. An interim report (Garet et al. 2010) described the findings after one year of PD. The current…

The study examined whether 7th-graders' knowledge of rational numbers improved when the students' math teachers participated in related professional development activities. The study analyzed data on about 4,500 students and 200 teachers from approximately 80 schools in 12 districts during the 2007-08 academic year. The study found that students…

Using data collected in 125 seventh-grade and 56 eighth-grade Texas classrooms in the context of the "Scaling Up SimCalc" research project in 2005-07, we examined relationships between teachers' mathematics knowledge, teachers' classroom decision making, and student achievement outcomes on topics of rate, proportionality, and linear…

Parent, school, and community engagement is widely established as a collaborative strategy to improve the school experience and educational outcomes for children and youth (Epstein & Sanders, 2006; SEDL, 2013; Weiss, Lopez, & Rosenberg, 2011; Barr & Saltmarsh, 2014). Consistent with this viewpoint, the Houston Independent School…

In K-12 classrooms, as well as on the college and university level, the incorporation of digital games has played a vital role in the educational system. While introducing teachers to new fields, these digital games have been designed and implemented for the classroom and have shown positive results at a variety of educational levels. Cases on…

The purpose of this study is to compare the efficacy of three different approaches to professional development in Earth science education: preparing teachers to "adopt" expert-"design" curricula; preparing teachers to use a principled approach to design curricula; and preparing teachers to use a principled approach to "adapt" curricula. The claims…

This article reports on the results of a mixed method case study investigating the relationship between professional learning community (PLC) activities and teacher improvement in a first-year middle school. Data were collected from core academic sixth, seventh, and eighth grade teachers using a professional development survey, teacher interviews,…

These proceedings contain the papers of the IADIS International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2013), October 22-24, 2013, which has been organized by the International Association for Development of the Information Society (IADIS), co-organized by The University of North Texas (UNT), sponsored by the…
