Teachers' attitudes and intentions play an integral role in the integration of technology into their lesson designs for mathematics. All K-8 students at the research site are now one to one with a device, either a tablet or laptop, depending on their grade level. It is up to teachers to determine how and when to integrate technology into their…

(Purpose) This study aimed to evaluate the efficacy of Imagine Math by comparing the performance of program users and non-users on the NWEA MAP Growth Math assessment. (Methods) Propensity score matching was utilized to compare statistically similar southeastern U.S. charter school students who used or did not use the Imagine Math program during…

This extensively updated teaching resource provides over 100 engaging, full-color visuals with explanations of how they can be used to stimulate mathematics learning, to explain mathematical concepts, and to assess students' mathematical understanding in grades K-8. Readers are provided with a strong mathematical background, downloadable copies of…

Teachers must meet a variety of students' mathematics learning needs but are often not trained to do so. Little is known about how teachers perceive their efficacy to meet diverse math learning needs. The purpose of this qualitative collective case study was to explore teacher attitudes and perceptions of professional development (PD) and…

Equivalence is a concept that comes up across the entire K-12 grade span and in many different areas of mathematics. Students who are bureaucratically designated as "English Learners" can explore equivalence across their K-12 academic careers while developing language to connect ideas. Drawing on what is known generally from theory and…

Teachers' beliefs, knowledge, and decisions can affect the way teachers teach, and, consequently, what students learn. Self-efficacy beliefs may also interact with beliefs about the most appropriate and effective teaching and the selection of instructional practices to implement. We examined the relationships among teachers' mathematics…

Over the past two decades, the landscape of research on mathematics teacher educators (MTE) has grown considerably. One particular area of interest has focused on the knowledge needed by MTEs for their work with preservice K-8 teachers (PTs). In an effort to understand this varied landscape, we conducted an extensive review of research on…

Delve into the transformative journey of teachers and administrators from a rural school district as they bring "Principles to Actions" to life. Pawnee City Public Schools believes effective teaching affects student learning and implemented a successful district-wide plan to improve student learning through the eight Mathematics Teaching…

Research has demonstrated strong relations between spatial skill and mathematics across ages and in both typical and atypical populations, suggesting that a significant proportion of variance in mathematics performance can be explained by variance in spatial skill. Why do these relations exist and how do they develop? Studies of dimensionality in…

We describe here lessons learned in designing an early algebra curriculum to measure early algebra's impact on children's algebra readiness for middle grades. The curriculum was developed to supplement regular mathematics instruction in Grades K-5. Lessons learned centered around the importance of several key factors, including using conceptual…

Math proficiency in the elementary grades is one component to ensuring a highly qualified science, math, engineering, and technology workforce. The literature indicates that teachers of those early years greatly impact their students' future attitudes and abilities in the STEM fields. Therefore, it is critical that administrators, teacher…

This meta-analysis synthesized research on math performance outcomes for English learners (EL) as a function of language-focused (math vocabulary) interventions. We included group and single-subject design studies with children from kindergarten to 8th grade (3,766 students for group, 30 for single-subject). Group studies yielded a mean Hedges' g…

This study explored how two professional development approaches to reforming math instruction with different mechanisms for fostering change might have valuable synergies when used in tandem to support take-up, i.e., teachers' acceptance, adoption, and incorporation of ideas into practice. This investigation of Practice-Based Professional…

The authors who are mathematics teacher educators, have found that classifying, composing, and transforming shapes (in particular, rotations and reflections) are areas of difficulty for adults as well as for children. However, these are also some of the most important geometric ideas. They are fundamental topics in the K-8 Geometry and Measurement…

The development of proofs and argumentation is one of the major standards for mathematical practices in K-12 education that researchers and practitioners alike are continuing to improve. Further, the use of discourse is considered essential in the learning of mathematical concepts at these levels. However, K-12 educators continue to confound how…
