Despite progress toward gender equity, troubling disparities in mathematical problem-solving performance and related outcomes persist. To investigate why, we build on recurrent findings in previous studies to introduce a new construct, “bold problem solving,” which involves approaching mathematics problems in inventive ways. We introduce a self-report survey of bold problem-solving orientation and find that it mediates gender differences in problem-solving performance for both high-achieving middle school students (n = 79) and a more diverse sample of high school students (n = 222). Confidence mediates the relation between gender and bold problem-solving orientation, with mixed results for mental rotation skills and teacher-pleasing tendencies as mediators. Overall, the new bold problem-solving construct appears promising for advancing our understanding of gender differences in mathematics.

Growing Problem Solvers provides four original, related, classroom-ready mathematical tasks, one for each grade band. Together, these tasks illustrate the trajectory of learners’ growth as problem solvers across their years of school mathematics.

Examples are an essential part of mathematics teaching and learning, used on a daily basis to teach and practice content. Yet, selecting good examples for teaching is complex and challenging. This article presents ideas to consider when selecting examples, drawn from a research study with algebra 2 teachers.

The field of mathematics teacher education has been moving collectively toward a common goal of preparing prospective mathematics teachers to teach with technology. In this article, we present findings from a national survey of accredited university secondary mathematics teacher education programs. The purpose of the study is to describe the current state of the ways in which programs are preparing preservice teachers to teach secondary mathematics with technology.

Modify arithmetic problem formats to make the relational equation structure more transparent. We describe this practice and three additional evidence-based practices: (1) introducing the equal sign outside of arithmetic, (2) concreteness fading activities, and (3) comparing and explaining different problem formats and problem-solving strategies.
