This study examines informal hypothesis testing in the context of drawing inferences of underlying probability distributions. Through a small-scale teaching experiment of three lessons, the study explores how fifth-grade students distinguish a non-uniform probability distribution from uniform probability distributions in a data-rich learning…

In this study, we examined and compared volume and volume-related lessons in two common core aligned U.S. textbook series and Korean elementary textbooks. Because of the importance of textbooks in the lesson enactment process, examining what textbooks offer to students and teachers is important. Since different parts of a textbook provide…

Overall mathematics proficiency of fourth graders in the U.S. continues to be poor and students falling at or below the 25th percentile display declining performance (NCES, 2017), which suggests the need for schools to provide supplemental intervention supports as soon as skill gaps are observed. Unfortunately, there is a paucity of small group…

The contribution focuses on issues related to the implementation of formative assessment methods into inquiry based teaching, by means of issues related to solving twelve multiple-step arithmetic word problems based on operations with natural and rational numbers. These word problems have multiple correct solution procedures and the presented…

This review protocol guides the review of research that informs the What Works Clearinghouse (WWC) "Preparing Young Children for School" practice guide and related intervention reports. The review protocol is used in conjunction with version 4.1 of the "WWC Standards Handbook" and "WWC Procedures Handbook." The new…

This paper examines the impact of increasing teacher salaries on student outcomes by exploiting variation from the "50K The First Day" campaign that established a $50K salary floor for new teachers across New Jersey school districts. Using school-level data from 2003 to 2019, we employ a staggered difference-in-differences (DiD) approach…

Direct Behavior Rating (DBR) has been proposed as a promising approach to assess student behavioral progress in classroom settings. The current study examines raters and occasions as well as their interactions as sources of error in the use of DBR--Multi-Item Scales (DBR-MIS) and DBR--Single-Item Scales (DBR-SIS) for academically engaged (AE) and…

Long-standing and ongoing calls exist for making mathematics meaningful, relevant, and applicable outside the classroom. Major mathematics education organizations (National Council of Teachers of Mathematics [NCTM], National Council of Supervisors of Mathematics [NCSM], Association of Mathematics Teacher Educators [AMTE], TODOS: Mathematics for…

Despite the rapid development of motion-based technologies, their role in embodied learning remains ambivalent. This study aimed at investigating the potential added value of motion-based technologies in the context of geometry elementary education. An explanatory sequential design was adopted, composed of two phases. First, an experiment was…

The purpose of this qualitative descriptive study is to examine how 3rd-8th grade teachers describe their use of educational technology for experiential learning in mathematics in the Southwestern United States. David Kolb et al. (2001) experiential learning theory guided the two research questions on the level of use and how teachers described…

Mathematics Anxiety (MA) and Mathematics Teaching Self-Efficacy (MTSE) have been reported as factors related to teachers' mathematics instruction. This study investigated MA and MTSE in in-service elementary teachers' virtual mathematics instruction. A comparative case study design was used to understand the relationship between MA, MTSE, and…

In conjunction with the Council of Chief State School Officers (CCSSO) and governors across the nation, the initial drafts of the Common Core State Standards (CCSS) were introduced in 2009 with the final draft being released in 2010. With a goal of eliminating stagnant academic progress, the Standards were written to outline precisely what…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction on math achievement, as measured by SBA scores. We compared students in schools using i-Ready Personalized Instruction school-wide (Treatment students) and students who only received i-Ready Diagnostic assessments and who were in schools only partially…

Educational technology (EdTech) designers need to ensure population validity as they attempt to meet the individual needs of all students. EdTech researchers often have access to larger and more diverse samples of student data to test replication across broad demographic contexts as compared to either the small-scale experiments or the larger…

Mathematics educators and researchers have advocated for the use of manipulatives to teach mathematics for decades. The purpose of this article is to provide illustrative uses of a readily available manipulative rather than a complete list. From an Australian perspective, Pop-it fidget toys can be used across the mathematics curriculum. This paper…
