    This editorial focuses on defining and elaborating exactly what the authors mean by “the impact of educational research on students’ learning.”

    This Research Committee commentary describes how mathematics education researchers, or MERs, need to build on equity. The committee states that equity should no longer be a choice but an intentional, collective, and professional responsibility of the MER community.

    This study (n = 1,044) used data from the Teacher Education and Development Study in Mathematics (TEDS-M) to examine the relationship between field experience focus (instruction- or exploration-focused), duration, and timing (early or not) and prospective elementary teachers’ intertwined knowledge and beliefs about mathematics and mathematics learning. Findings suggest that field experience has important but largely overlooked relationships with prospective teachers’ mathematical knowledge and beliefs. Implications for future research are discussed.

    This article reports on elementary students’ understanding of time in the context of common classroom manipulatives and notational systems. Students in Grades 2 (n = 72) and 4 (n = 72) participated in problem-solving interviews involving different clocks. Quantitative results revealed that students’ performances were significantly different as a function of the tool available. Implications for theory and the treatment of time in curriculum and instruction are discussed.
