Taylor Lesner; Marah Sutherland; Madison Cook; Emily Wilke; Keith Smolkowski; Ben Clarke – Learning Disabilities Research & Practice, 2025
Understanding numerical magnitude is critical to the development of mathematics proficiency. Math interventions targeting magnitude knowledge have been shown to improve outcomes for students with math learning difficulties across grade levels. However, while recent studies have found that growth in magnitude knowledge mediates fractions…

Eugenio Chandía; Patricia Fuentes Acevedo; Natalia Ruiz; Daniza Rojas; Mirian Baeza; Cristian Reyes – International Electronic Journal of Mathematics Education, 2025
The study investigates the knowledge profiles of elementary pre-service teachers (PST) concerning numbers and operations before their professional classroom practice. By validating an instrument through exploratory and confirmatory factor analyses, it identifies and categorizes the PST' performance into distinct profiles based on the mathematical…

Caroline Cohrssen; Jill Fielding; Jo Bird – Early Childhood Education Journal, 2025
There is growing interest in mathematics learning progressions in early childhood education. Counting is a skill usually developed early in life. The application of the counting principles in early childhood typically entails counting objects. This poses challenges for learning about zero. Indeed, the word "zero" is seldom used in the…

Randall E. Groth; James P. Barry – Statistics Education Research Journal, 2025
Numerous variants of Kahneman and Tversky's (1972) hospital problem have been used to investigate intuitions about the Empirical Law of Large Numbers (eLLN). A largely separate line of research has focused on interactions between context knowledge and statistical reasoning. The present study merges these two lines of research by analyzing tertiary…

Xia Li; Colleen Maas; Colleen Oppenzato – Early Education and Development, 2025
Research Findings: The aim of this study was to investigate U.S. preschool teachers' math pedagogical content knowledge in number comparison. Seventy-four in- and pre-service teachers completed a set of scenario-based questions from a researcher-designed questionnaire that is composed of learning scenarios. Through a mixed-method approach, the…
