Rising inequality in the United States has raised concerns about potentially widening gaps in educational achievement by socio-economic status (SES). Using assessments from LTT-NAEP, Main-NAEP, TIMSS, and PISA that are psychometrically linked over time, we trace trends in achievement for U.S. student cohorts born between 1954 and 2001. Achievement…

This randomized controlled trial examined effects of the MyTeachingPartner-Math/Science intervention on the quality and quantity of teachers' mathematics and science instruction, and children's mathematics and science outcomes in 140 pre-kindergarten classrooms. Teachers participated in the intervention for two years with consecutive cohorts of…

This book, compiled in honor of Chair Professor Frederick K. S. Leung, contributes to revisiting, renewing and enriching the knowledge of cultural matters to mathematics education, widening the horizon in the use of cultural perspectives to explain the characteristics of classroom teaching and learning in East Asia, and to explain/re-interpret the…

The purpose of this study is to determine the progression of exemplifying and example generalization by students. We investigated whether example generalization occurs by analyzing collected data by identifying whether students recognize, describe, and define general features of geometric examples. We also investigate how example generalization…

Drawing strategies are widely used as a powerful tool for promoting students' learning and problem solving. In this article, we report the results of an inferential mediation analysis that was applied to investigate the roles that strategic knowledge about drawing and the accuracy of different types of drawings play in mathematical modelling…

The Trends in International Mathematics and Science Study (TIMSS) makes it possible to compare the performance of students in the US in Mathematics and Science to the performance of students in other countries. TIMSS uses four international benchmarks for describing student achievement: Low, Intermediate, High, and Advanced. In this study, we…

Research studies proved that teachers' self-efficacy is directly related to students' academic achievement and overall learning. The current study was conducted to explore relationship of mathematics teachers' self-efficacy with students' academic achievement at secondary level. A sample of 576 respondents with a break up of 96 math teachers (48…

The aim of this research is to analyze the effects of realistic mathematics education on students' self-reports on the 'numbers and operation' unit of the 5th grades mathematics course. For this reason, two classes were randomly identified. After seeing that the groups were equivalent using the Achievement Test of Group Equivalency (ATGE),…

The sixth grade is very important for education stakeholders, as it marks the beginning of the transition period for students to high school. No consensus has been reached so far among scholars on whether block scheduling is the best way to provide students the time that is necessary to facilitate effective learning and the retention of knowledge.…

Each of the states bordering Mississippi invests large amounts of money in providing children with state-funded pre-k programs in their public schools. However, Mississippi falls behind these states and does not similarly invest in this effort to provide many of its children with the opportunity to attend state-funded pre-k programs. Because…

The impostor phenomenon is a psychological self-belief that one does not deserve the accolades that one has legitimately earned. Impostorism negatively affects individuals' cognitions, behaviors, and expectations, but possibly not in "all" aspects of their lives simultaneously. Presently, we reconceptualize the impostor phenomenon as a…

It is common to assume that worker productivity is normally distributed, but this assumption is rarely, if ever, tested. We estimate the distribution of worker productivity, where individual productivity is measured with error, using the productivity of teachers as an example. We employ a nonparametric density estimator that explicitly accounts…

Concrete manipulatives and dynamic geometry software (DGS) are both commonly used for geometry education in elementary and middle schools. This study sets out to understand which of the two approaches was better in improving the conceptual understanding of quadrilaterals for fifth graders. A pre-/post-test design was conducted in which the same…

In this study, the mediating roles of perceived teacher support and students' mathematics self-beliefs on the feedback process were investigated in The Programme for International Student Assessment (PISA) context in Turkey. PISA 2012 mathematics scores and questionnaire responses of 4848 15-year-old students were analyzed. Results indicated that…

Understanding spatial reasoning is important to success in mathematics. This article shows how the proficiency strands in the "Australian Curriculum: Mathematics" provide the tools needed for effective teaching and learning of spatial thinking.
