This action research study employed a mixed-method design to examine the impact of a number talks intervention on the number sense development and mathematical proficiency of students in one third-grade mathematics class. The number talks strategy was also studied to determine its impact on third-grade students' development of a productive…

Students with disabilities lack access to and achievement in rigorous and cognitively challenging mathematics and are typically subjugated to rote and remedial forms of mathematics education in segregated settings. In this presentation, I argue that teacher educators, guided by disability studies in education (DSE) concepts, can support…

The number of students taking online distance education (ODE) courses as part of their programs of study has steadily increased since 2012 (Seaman, Allen, & Seaman, 2018). This has led to a proliferation of resources related to online teaching pedagogy (Dennen, 2013). In many cases, instructors of ODE courses are left to sort through this…

The purpose of this quantitative correlational study was to ascertain the degree to which a relationship exists between teacher-reported technology integration in the classroom and student math achievement of classrooms containing third through fifth grade students in one Southern California school district, as measured by a standardized…

Problem-solving occurs when mathematical tasks create opportunities that provide challenges for increasing students' mathematical understanding and development. This research study determined the influence of the "launch-explore-summarize/extend" problem-solving framework on second-grade student performance of place value tasks. The…

This paper examines the implementation of an instructional module on Preservice Elementary Teachers' (PSETs) professional noticing of children's mathematical thinking as defined by Jacobs, Lamb, and Philipp (2010). The module focuses on professional noticing skills through the content focus of early algebraic reasoning and uses complex video…

Why do certain objects or images such as a piece of furniture, an item of clothing, or even a flower appear visually attractive? The most obvious factors must involve aspects such as size, colour, movement and discrepancy such as in looking at a Salvador Dali painting. Yet there is another subtle factor associated with shape that also can demand,…

Assessments that function close to classroom teaching and learning can play a powerful role in fostering academic achievement. Unfortunately, however, relatively little attention has been given to discussion of the design and validation of such assessments. The present article presents a framework for conceptualizing and organizing the multiple…

The aim of this study is to employ the Pirie-Kieren model so as to examine the understandings relating to the domain of multivariable functions held by primary school mathematics preservice teachers. The data obtained was categorized according to Pirie-Kieren model and demonstrated visually in tables and bar charts. The study group consisted of…

Using a convergent parallel mixed methods design, this exploratory study examined mathematics lessons in two third-grade classrooms to analyze the mathematical classroom discourse when using tutorial instructional software. A chi-square test for independence revealed statistically significant correlations between teachers use of the focusing and…

This article explores the benefits of using digital technology to support and enhance students' understanding during mathematical inquiry. The use of digital technologies enabled students to focus on the problem-solving aspects of the task such as how to compare and represent the data effectively.

Technology integration in K-12 mathematics has received increased attention in the last decade as new mathematical technologies have been developed and implemented more often. There is a need for further research on these technologies and for effective implementation practices of technology in mathematics education in general. in practice,…

Since many decisions in politics, economics, and social sciences are based on statistics, statistical literacy is a key component for an active citizen. Statistical skills and statistical reasoning can already be enhanced in primary school. Therefore, not only in Germany, statistics is an element of the primary-school curriculum, which usually…

This paper presents findings from a two-year qualitative study examining integration of computer science (CS) and computational thinking (CT) into elementary mathematics instruction. Integrated units were developed by elementary teachers and CS/CT coaches with support from university faculty with expertise in CS/CT and elementary mathematics.…

Reasoning underpins students' mathematical understanding and promotes creative thinking. It is regarded as a key mathematical proficiency. This article discusses the reasoning actions that primary children employed and teachers noticed for the "What else belongs?" task focused on forming and testing conjectures.
