To provide effective fractions instruction, teachers need deep understanding of fraction concepts (i.e., content knowledge) and skill in using visual representations of fractions to support student learning (i.e., pedagogical content knowledge); yet, research indicates that many pre- and in-service teachers lack knowledge in both areas. The…

This article presents a large-scale longitudinal study of hundreds of students across the state of Kentucky that participated in a dual-focus mathematics intervention initiative when they were in the third grade. Rather than an exclusive focus on intervention, this initiative focused on both (i) high quality pull-out intervention and (ii)…

Many colleges and universities recently piloted and adopted the co-requisite model of delivery of developmental mathematics while offering more options for students to fulfill their mathematics requirement. We discuss our process for piloting and ultimately implementing the co-requisite model at our university, provide preliminary data on student…

Proficiency with mathematics requires an understanding of mathematical language. Students are required to make sense of both spoken and written mathematical terms. An essential component of mathematical language involves the understanding of the vocabulary of mathematics in which students connect vocabulary terms to mathematical concepts or…

This study aims to investigate how the different solutions, problem-solving strategies, and the number of strategies used by the preservice secondary school mathematics teachers on non-routine mathematical problems change according to grade levels. This study was conducted with 152 preservice teachers studying at the department of elementary…

Regular contributors James and Toby Russo return with a sixth principle for educationally-rich mathematical games--almost all mathematical games have the potential to be transformed into an investigation. This article builds on their earlier piece with Leicha A Bragg (APMC 23(3), 30-34). [For "Five Principles of Educationally Rich…

Few research studies within the field of mathematics education have focused on the ability to recognize quantities quickly and accurately without counting (i.e. subitizing). The aim of this research was to empirically explore the role of conceptual subitizing activities for enhancing preschool class children's learning of the part-part- whole…

The South African education system bears evidence of fluctuations in the final Grade 12 mathematics marks occurring across different learner profiles. This study reflected on the National Senior Certificate (NSC) mathematics results from the Western Cape Education Department for the years 2009 to 2014, the period just after the introduction of the…

Negative relationships between mathematics anxiety and achievement appear in many countries globally (Lee, 2009; OECD, 2013), suggesting that mathematics anxiety could be an underconsidered factor in regions with persistently low mathematics achievement. We draw on a national sample of students and their teachers in Belize to examine relations…

Mathematics is presented in non-STEM disciplines as a subject that helps students acquire tools they will need in their future careers. Therefore, the need for instruction in mathematics demands content, oriented not only towards fundamental principles and techniques, but also towards their application in a specific context. By directing the…

This paper leverages an intrinsic approach to the conception of mathematical knowledge for teaching (MKT) to show how it can be used to examine teachers' MKT. In this qualitative study, I interviewed eight practicing teachers using tasks designed to generate data regarding their (a) personal interpretations of slope, (b) understanding of how…

There is anecdotal evidence that many elementary teachers integrate mathematics lessons and art activities by having students first make colorful, rich material that is subsequently used in an instructional activity. However, it is unclear whether such activities effectively promote learning and transfer of mathematical concepts. The goal of the…

In this paper, we present our perspective about the importance of teaching Gödel's incompleteness theorem in formation courses to mathematics teacher. The phenomenon of incompleteness evidenced by the incompleteness theorem is manifested by the existence of true propositions about natural numbers that cannot be proved by any metamathematical…

The purpose of this study was to determine to what extent the completion of a note taking and review intervention impacted developmental mathematics students' performance on course assessments. Note taking is a challenging skill that requires time and effort to improve (Boch & Piolat, 2005). Many developmental mathematics students struggle to…
