In this paper I explore the question of what counts as successful implementation of a mathematics professional development (PD) project at scale. Two kinds of upscale are presented and differentiated from one another: upscale of settings and upscale of values, and the link between this differentiation and how success may be defined is discussed.…

The present study evaluated the effects of a program designed to promote a growth mindset in maths teachers (i.e., the belief that maths ability can improve through experience and learning) to enhance teaching and learning outcomes in their maths classes. The sample was composed of 155 Israeli high-school maths teachers who were randomly assigned…

This study describes a teaching process that offers teachers and pupils ways of constructing the division operation through illustration based on defining the reference unit (divisor), the reference whole1 and the dividend. We introduce a computerized dynamic environment, using an Excel spreadsheet, in which both teachers and pupils can…

The aim of the study was to examine the effect of an activity with an educational electronic storybook with math content on the emergent math of kindergarteners at risk for learning disabilities (LD) compared with kindergarteners with typical development (TD). The study included 107 kindergarteners aged 4.6 to 7. Both the participants at risk for…

This study explored what was entailed in implementing a professional development (PD) designed in the United States (US) to a different, Israeli, context. To achieve this goal, the first step was empirically examining the effectiveness of such a PD using quantitative methods. We then examined which adaptations were made in the imported PD and at…

This article describes the beneficial effects of an intervention program, based on the computerized Origametria program and the GeoGebra environment, for acquiring geometric concepts in the second grade. Eighty-eight second-graders, from both Hebrew-speaking and Arabic-speaking schools, were instructed in groups by eighteen Hebrew and…

In order to reach gender equity in the gifted population, an affirmative action policy was instituted in Israel to increase the number of girls identified as gifted. The purpose of this study was to compare the self-efficacy beliefs of girls in the top 1.5% (gifted girls (GG)) with those of girls in the top 3% (GG in affirmative action). It was…

The present study investigated the effectiveness of a cognitive enrichment programme as a tool for enhancing the chances of immigrant and minority students to be admitted to a technological college. Students received two weekly sessions (four hours) of "Instrumental Enrichment" (IE) during the second semester of the college preparatory…

This study investigated mathematics teachers' professional knowledge among elementary school teachers exposed to a professional training program that either supported self-regulated learning (SRL) or offered no SRL support (no-SRL). The SRL support was based on the IMPROVE metacognitive self-questioning method that directs students' attention to…

In this study we created, implemented, and evaluated the impact of proportional reasoning authentic investigative tasks on the mathematical content and pedagogical knowledge and attitudes of pre-service elementary and middle school mathematics teachers. For this purpose, a special teaching model was developed, implemented, and tested as part of…

This study provides a comprehensive look at a constructivist one-to-one computing program's effects on teaching and learning practices as well as student learning achievements. The study participants were 476 fourth and fifth grade students and their teachers from four elementary schools from a school district in the Dallas, Texas, area. Findings…

This document contains the second volume of the proceedings of the 30th Annual Conference of the International Group for the Psychology of Mathematics Education. Conference presentations are centered around the theme "Mathematics at the Centre." This volume features 60 research reports by presenters with last names beginning between Abr…

The objectives of the current study were to examine: (a) the effects of the Peer Mediation with Young Children (PMYC) program on mediators' and learners' mediation style in the context of maths teaching; and (b) the interaction effects of the intervention program, children's verbal ability, and maths level on pre-to post-intervention improvement…

The study was designed to enhance teachers' understating of students' learning by using assessment tasks. Four third-grade teachers and the researcher collaboratively set up a school-based assessment team in the two-year Assessment Practices in Mathematics Classroom project that assisted teachers in implementing assessment as integral part of…

Socially disadvantaged Israeli children in grades three or six were paired with university student tutors. Mathematics and reading achievement were measured after one year of tutoring, two years of tutoring, or no intervention. One year of tutoring yielded some gains; however, a second year did not increment them. (Author/GDC)
