Many mathematics educators believe a goal of instruction is for students to obtain conviction and certainty in mathematical statements using the same types of evidence that mathematicians do. However, few empirical studies have examined how mathematicians use proofs to obtain conviction and certainty. We report on a study in which 16 advanced…

One of the well-known approaches to creativity differentiates between creative person, process, product, and press. In the study presented in this paper we focus on creative process and product associated with Problem Posing through Investigation (PPI) by experts in mathematical problem solving. We link the creative process to creativity of PPI…

Students exhibiting mature number sense make sense of numbers and operations, use reasoning to notice patterns, and flexibly select the most effective and efficient problem-solving strategies (McIntosh et al., 1997; Reys et al., 1999; Yang, 2005). Despite being highlighted in national standards and policy documents (CCSS, 2010; NCTM, 2000, 2014),…

It is well known that students benefit from opportunities to interpret and create different representations (e.g., diagrams, graphs, tables, symbols) of mathematical ideas. Employing Marton's Variation theory as a lens, I argue for an expansion of the use of multiple representations in task design for graphs: Incorporate two different forms of the…

Numerous studies have shown a significant positive relationship between the mental representation of hands in young children and their calculation performance. The literature indicates that certain components of manual motor skills may be critical to the quality of this relationship. The main objective of this study is to measure the benefit of an…

Many students struggle with mathematics, in Norway a pressing concern is the decline in proficiency in high school, and the increased number in need of special education. Assessments of proficiency levels are traditionally done through norm- and criterion-referenced achievement tests, who will rarely detect students struggling or identify…

This study aims to explore the notion of the density of the set of rational numbers in the set of real numbers, as interpreted by undergraduate mathematics students. The data comprise 95 responses to a scripting task, in which participants were asked to extend a hypothetical dialog between two student characters, who argue about the existence of…

Sound mathematical knowledge is an essential ingredient for student success in many disciplines, and quality mathematics support is crucial to that success. How that support is delivered is often the key to student engagement, satisfaction and positive outcomes. Many students require sound mathematical knowledge to engage in their discipline…

Background: Use of numerical and spatial language, also known as math talk, is critical to the development of foundational number and spatial skills in early childhood. However, caregivers and children of low socioeconomic status (SES) tend to use less math talk than their higher-SES peers. Objective: The current efficacy study tested the…

Mathematical modeling is a high-leverage topic, critical for college and career readiness, participation in STEM education, and civic engagement. Mathematical modeling involves connecting real-world situations, phenomenon, and/or data with mathematical models, and in this way applies across various STEM disciplines, including mathematics,…

Mathematics is traditionally taught using direct instruction, which has been found to engender negative affective responses towards the subject, including anxiety and low self-efficacy (Borko et al., 1992; Mischo & Maas, 2013). Direct instruction places authority on the instructor and involves teaching students about mathematics instead of…

This paper examines the prevalence of incomplete educational qualifications and consider the importance of both background characteristics and numeracy skills as predictors of non-completion. The paper analyzes data from the Program for the International Assessment of Adult Competencies (PIAAC) to address the following research questions:…

In this dissertation, the effects of bilingual immersion curriculum versus monolingual curriculum on achievement of students in a select elementary school were examined. The researcher explored mathematical and reading achievement as measured by formative kindergarten through third grade assessments in a southeastern elementary school. Hypotheses…

This action research aimed to assess the impact of online homework, delivered via IXL, on thirteen 8th Grade Mathematics students' mathematical proficiency and explored their perceptions of its usefulness. The Cedar Hill Middle School students typically scored below state and national averages in mathematics, necessitating increased rigor and…

Counting is foundational to success with mathematics. In this synthesis, we analyzed 17 studies about counting-focused interventions for preschool and kindergarten students with mathematics difficulty or at-risk of mathematics difficulty. All interventions addressed several components of counting, including stable order, one-to-one correspondence,…
