Research on numerical cognition, an emerging area that has received increasing interest in Chile, can contribute to understanding how mathematical skills are developed and support education. This article reviews the studies published in the field of numerical cognition in Chile, indexed in the WoS, PubMed, Scopus and SciELO databases. The articles reviewed address mechanisms that underlie mathematical performance and strategies used by children, adolescents and adults to solve mathematical tasks, with a special emphasis on early skills, calculations and arithmetic, as well as factors associated with individual differences in the development of mathematical notions. This article also analyses the sources of funding that support research on numerical cognition and education in Chile and the projects awarded such funds in recent years. Finally, the contribution and challenges of numerical cognition research in Chile in an educational context are discussed. [ABSTRACT FROM AUTHOR]

In Chile, national and international standardized tests have revealed major differences in mathematics achievement in favor of boys. This study sought to determine whether gender differences exist in classroom interactions and examined the relationship between teachers' beliefs and their pedagogical practices. Forty 7th grade mathematics lessons taught in Chilean public schools by 20 educators selected via convenience sampling were video-taped. Pedagogical interactions were coded by gender and a self-report questionnaire on beliefs was administered to the teachers. Descriptive analyses were conducted. The Wilcoxon test and the Mann-Whitney U test were used for group comparisons. It was observed that teachers ask boys significantly more questions requiring complex cognitive processes and provide more feedback to boys, and also that boys participate significantly more in class than girls. There are no differences between male and female teachers regarding these practices. In addition, preliminary evidence was found of a concordance between beliefs and practices in teachers who reported explicit gender stereotypes associated with mathematics learning.
