The United States has relinquished its mathematical prowess enjoyed in the 20th century with trending declines in performance on international and national measures and must make a concerted effort to regain this standing in the 21st century. Success in mathematics education also is important for individual citizens because it gives them college…

This paper reports on an exploratory study about probabilistic intuition in learning mathematics for decision-making. The analysis was carried out on a group of high school students in relation to their probabilistic intuition in problem-solving, after performing playful learning activities on a simulation platform specifically designed for this…

This article presents an original puzzle that supports students' development of visual thinking and geometry ideas based on the Van Hiele levels of geometric thought. The "Triangle Puzzle" is one of many tools teachers can use to guide students' learning of geometry. The Van Hiele's theory provides a way to assess and support this…

When given the opportunity to play with mathematical materials and ideas, children demonstrate their mathematical understanding in innovative ways. The open-ended nature of the "Pattern Blocks" activity provides agency for children to decide how to approach the tasks, ways to differentiate beyond more common pattern-block puzzle choices,…

This article describes how integrating children's literature in mathematics classrooms has proven to provide a common context that is suitable for problem solving and modeling that advances mathematical thinking and reasoning. The engaging task inspired by children's literature allowed this teacher to infuse science, engineering, technology, and…

The objective of this research was to evaluate the learning management and learning assessment abilities of preservice teachers in the Mathematics field. Additionally, it aimed to provide guidelines for the development of these abilities. The study group consisted of 34 practicum teacher students, 34 mentor teachers, and 14 experts. Data…

Previous research on the gender gap in mathematics indicates that, in the case of Spain, the gap is stable and has even increased during the last years both in primary and secondary education. The objective of this paper is to analyze whether this gender gap remains by changing the academic level and the way of measuring performance. A sample of…

The COVID-19 pandemic led to a global lockdown and compelled institutions to shift to emergency remote teaching. This transition and the lack of knowledge of using technology affected teaching practices, including assessment. Confronted with new contexts for assessment and threats to validity caused by ineffective proctoring, many instructors had…

Due to the growing interest in the integration of ethnomathematics in mathematics education, we undertook a systematic literature review and bibliometric analysis of research on the incorporation of ethnomathematics in geometry teaching from 2011 to 2021. The search for 37 relevant research articles was done on Google Scholar, Scopus, and by hand…

This case study explored Grade 12 learners' misconceptions in limits of functions. The study aimed at understanding problems that learners face in learning the concepts of limit by analyzing misconceptions that learners have and identifying the possible sources of these misconceptions to take remedial action. An exploratory research design was…

This quantitative research collected information from secondary mathematics educators about their self-efficacy on technology use, their technological, pedagogical, and content knowledge (TPACK), and their level of technology implementation according to the levels on the SAMR model. These four levels are Substitution, Augmentation, Modification,…

In this article, the authors share one approach to Number Talks that may help more students participate, increase access to and learning of mathematics, and provide some variation in routines. Number Talks are commonplace in the elementary mathematics classroom, thanks to Parker and Humphreys (e.g., 2018) and Parrish (e.g., 2011). They are a…

Mathematical modelling (MM) plays a pivotal role in the integration of Science, Technology, Engineering and Mathematics (STEM) into school studies. This current empirical study suggests using a four-step solution plan as a scaffolding tool during the instruction of MM tasks in a STEM context in formal school mathematics. The study goals are…

Making sense of algebraic expressions in context is multifaceted and extends beyond representing real-world situations using algebra. As part of Project MathTalk, the authors created videos that feature a pair of Grade 9 algebra 1 students coming to understand algebraic expressions in context. The students found three aspects of making sense of…

The current longitudinal study measured 279 kindergartners' (M[subscript age] = 5.76 years; SD = 0.55; 135 females) place value understanding using both approximate and syntactic measures based on previous evidence that early variation in performance on approximate measures was associated with subsequent syntactic place value understanding. In the…
