Lesson study, especially when conducted with support from targeted resources, is often identified as a potentially effective means to support teacher learning. In this study, 80 school-based teams of educators, representing 80 classrooms of third- or fourth-grade students in the US, were randomly assigned to one of four conditions: lesson study…

As parents, communities, educators, and policymakers continue to assess the impact of the COVID-19 pandemic on student learning in America, many have turned to recently released results from the National Assessment of Educational Progress (NAEP). NAEP measures what students know and what they can do in several tested subjects, including reading,…

In October 2023, the California Department of Education released test scores for all students in Grades 3-8 and 11 for the 2022-23 school year. These results represent an opportunity to analyze whether and to what extent student learning has rebounded after the dramatic declines in scores resulting from the COVID-19 pandemic and related school…

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 "striving learner" students who were assigned to use i-Ready Personalized Instruction (Treatment students) and "striving learner" students assigned to only receive i-Ready…

Cognitive, numeracy, and motivational factors have been implicated in math achievement. However, few studies have investigated these factors simultaneously and in middle childhood, limiting our understanding of the relative contributions of these factors during an important developmental period. The current study investigated how one numeracy,…

Explore Learning contracted with LearnPlatform, a third-party edtech research company, to examine the relationship between student usage of Frax and math learning outcomes. Frax is a game-based, adaptive technology designed using the latest research on effective fractions instruction to support all learners in meeting early standards for fractions…

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…

A randomized controlled trial group design study funded by IES NCR Grant R305A090527 was conducted in which 16,307 3rd, 4th, and 5th grade students in 52 school grade-level clusters were randomly assigned to receive ST Math (program revision Gen3), a supplemental mathematics software instructional intervention, or to a business-as-usual…

The purpose of this quantitative correlational study was to ascertain the degree to which a relationship exists between teacher-reported technology integration in the classroom and student math achievement of classrooms containing third through fifth grade students in one Southern California school district, as measured by a standardized…

This study finds that, breaking with decades of slow improvement, U.S. reading and math scores on the National Assessment of Educational Progress (NAEP) and other assessments have seen historic declines since most states implemented national Common Core English and math curriculum standards six years ago. This descriptive analysis is designed to…

Resilience, as defined by the literature, deals with the relationship between individuals and their environment. This capstone project followed elementary students over a three-year period to investigate and determine the impact a co-teaching intervention model has on resilience, grade-point average (GPA), state testing scores in English language…

The research featured in this paper is part of the CORE-PACE Research Partnership, which is focused on producing research that informs continuous improvement in the CORE districts as well as policy and practice in California and beyond. In this report, the authors used data from multiple interim assessments to examine how the rate of student…

Many math students, both EL and non-EL, struggle to reach the level of proficiency on California state tests which is required since the passage of NCLB in 2002 (California Department of Education, 2012). In California only 34% of students scored at the level of proficiency or above in 2011 (National Assessment for Educational Progress, 2012). The…

We estimate relative achievement effects of the four most commonly adopted elementary mathematics textbooks in the fall of 2008 and fall of 2009 in California. Our findings indicate that one book, Houghton Mifflin's "California Math," is more effective than the other three, raising student achievement by 0.05 to 0.08 student-level…

The Early Fractions Test is a paper-pencil test designed to measure mathematics achievement of third- and fourth-grade students in the domain of fractions. The purpose, or intended use, of the Early Fractions Test is to serve as a student pretest covariate and a test of baseline equivalence in the larger study. In this report, we discuss our…
