Effective classroom management is critical to supporting student learning and success in school. However, little research has focused specifically on the impact of classroom management on student mathematics achievement, especially in the early elementary grades or in a small group (i.e., Tier 2) context. To address this need we investigated the…

This study aims to develop a mathematics education program supported by stories for 48-60-month-old children attending pre-school education institutions and examine its effect on children's early mathematics skills. The study group consists of 48-60-month-old-children who continue pre-school education in an independent kindergarten affiliated with…

To learn mathematics, historically students had no choice but to memorize fundamental facts and apply memorized algorithms. Since 1995 in the US, all states have adopted standards to govern K-12 mathematics instruction, and in most, standards have de-emphasized memorization and emphasized reasoning based on concepts. This change assumed the brain…

The purpose of this study is to explore preservice teachers' (PTs') ability to implement multiple strategies using standard algorithms and alternative strategies and to investigate their conceptual knowledge of decimal operations. There were 37 PTs who participated in this study, all of whom attended a mathematics course in the K-8 Teacher…

When researchers code behavior that is undetectable or falls outside of the validated ordinal scale, the resultant outcomes often suffer from informative missingness. Incorrect analysis of such data can lead to biased arguments around efficacy and effectiveness in the context of experimental and intervention research. Here, we detail a new…

This mixed methods action research study examined the implementation process and impact of a 9-week Number Talk intervention to build number sense in kindergarten students. Fifty-eight kindergarten students engaged in daily Number Talk lessons for 9 weeks. Qualitative data were collected to evaluate the strengths and challenges of the…

Measurement instruments of early childhood teachers' mathematical pedagogical content knowledge (MPCK) have to consider the special characteristics of early childhood teaching. Early childhood teaching includes some planned activities but in contrast to learning in school, it is often motivated and generated by situations which unfold…

This mixed-method study explored the culturally responsive practices of a midsized, Southern California school district that used Expanded Learning Opportunities Program (ELOP) state funding to implement a voluntary summer program accessible to TK--6 grade students district-wide. Qualitative data gathered from semistructured interviews with the…

Mathematics education has experienced numerous reforms, including New Math of the 1960s, Back-to-Basics Math of the 1970s, and Standards-Based Math of the 1980s (Herrera & Owens, 2001; Osborne & Crosswhite, 1970). After the nationwide implementation of standards throughout the 1990s (Knight, 2007), Virginia developed high-stakes testing at…

The engage2learn approach to educator support provides an in-person and virtual coaching system that builds capacity and engagement in public schools. Engage2learn hired LXD Research to conduct an independent evaluation and analysis of NWEA Math and Reading data collected during the 2021-2022 school year. The goal was to measure how engage2learn…

Preparing students placing into developmental mathematics for success in undergraduate mathematics and preparing future teachers for the increasing demands of K-12 school settings are both persistent, yet seemingly divergent, problems facing higher education. In this paper, we shed light on a model that attempts to address aspects of each problem…

The effects of instructing kindergarten students (five-year-old in their first year of public school) on patterning were tested. Up to nine students in each class were randomly assigned to three groups in each of six classes, i.e., as many as three from a class in each group. One group received instruction on complex patterns similar to those…

The present study investigates and compares the influence of teaching Realistic Mathematics on the development of mathematical competence in kindergarten. The sample consisted of 231 Greek kindergarten students. For the implementation of the survey, we conducted an intervention, which included one experimental and one control group. Children in…

This study examines the influence of a year-long mathematics professional development program on Kindergarten teachers' beliefs, content knowledge, instructional practices, and their students' achievement. The professional development program is grounded in the theoretical construct of learner-centered professional development and focuses on…
