Addition of fractions is an important foundation for students to experience success in mathematics. This mixed-methods study was conducted to measure the effectiveness of robotics as a mathematics manipulative with seventh grade students. Two groups of students were established: control and treatment. The control group received teacher-centered…

The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

Engineering and integrated STEM experiences are being promoted at the K-12 level to increase interest and retention in STEM and to reinforce learning of mathematics and science content. However, research is still emerging regarding best practices for curriculum development, student impacts, and transfer of knowledge across disciplines. The purpose…

This report examines how students are performing across the entire 2020-2021 school year in reading and mathematics during the pandemic. Based on insights from millions of student assessments, the report explores key questions effected by COVID-19 in education, including: (1) How much did students grow during the 2020-2021 school year compared…

Today's classroom is the continuation of America as "the melting pot". Within this educational setting is an increased emphasis on student mathematical success as well as the acquisition of the English language by foreign-born students, whose families have come as an actualization of the American dream. Educators are striving to find…

One of the primary goals of teacher education is to aid preservice candidates in formulating a personal philosophy of teaching that is research-based. Teacher candidates should recognize that their philosophy of teaching and learning must be grounded in research-affirmed theory, certain dimensions of which (e.g., motivation) are critical to…

California's shift towards continuous improvement in education makes understanding how districts and schools can learn to improve a more pressing question than ever. The CORE Improvement Community (CIC), a network of California school districts engaged in learning about improvement together, is an important testing ground to learn about what this…

In spring 2015 Mississippi began testing the college readiness of all grade 11 public high school students and found that approximately 18 percent were ready for college math, a percentage that had changed little by 2017/18. This study examined: (1) the sequences of math courses that Mississippi students took in grades 6-11; (2) the math…

In explaining academic achievement, school climate and social belonging (connectedness, identification) emerge as important variables. However, both constructs are rarely explored in one model. In the current study, a social psychological framework based on the social identity perspective (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987) is…

Over the past thirty years, policies have been enacted at the local and state levels to reform mathematics instruction to be student-centered (see Cohen & Ball, 1990; Resnick, Stein, & Coon, 2008). Despite the wave of instructional reforms, several critical gaps remain in our understanding of student-centered mathematics instruction.…

In this study we investigated how 200 students in seventh grade (mean age = 12.38 years) solved simple addition problems and if the way they performed simple addition was related to their achievement in mathematics. Four performance groups were identified: proficient, almost proficient, inaccurate min counting and accurate min counting. More than…

Individual growth curves yield insights about growth that are not available from any other methodology; and developmental scales based on conjoint measurement models provide unique interpretive advantages for investigations of academic growth. The advantages are apparent when: (1) 15 consecutive statewide reading growth curves are annotated with…

Many (quasi-)experimental studies show that students tend to learn more in classes with better peers. However, the (presumably numerous) factors mediating the positive relationship between peer and own achievement have received less attention in the literature. I present evidence on one particular transmission channel: teachers tend to grade…

The literature suggests that while the number of students attending virtual charter schools continues to grow in Pennsylvania, math student academic performance in 6th and 7th-grade math in students attending cyber charter schools falls well below the state average. Although it is tempting to assume that the concern of summer slide would be…

This randomized controlled study investigated the efficacy of a Tier 1 intervention, schema-based instruction (SBI), designed to help students with and without mathematics difficulties (MD) develop proportional reasoning. Twenty seventh-grade teachers/classrooms were randomly assigned to a treatment (SBI) or control (business-as-usual) condition.…
