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…

While the ongoing academic impacts of the COVID pandemic in grades 3-8 has been well documented, far less is known about its effects on students who were in pre-K or kindergarten when the pandemic started in March 2020. In this brief, we focus on students who were in first and second grade in the 2021-22 school year, and for whom the majority of…

SC TEACHER's research mission includes publishing yearly reports that detail the South Carolina educator workforce, sharing insights with educators themselves, policymakers, community members, and other stakeholders. This report is an annual review of the state's public school teacher workforce. Analysis in this study uses statewide data from…

We present two types of validity evidence to support inferences and decisions about use of easyCBMs in relation to state testing programs. The first type involves the use of Benchmarks in reading to use in making predictions of performance on the Smarter Balanced (SB) test. These predictions can be made both well in advance (several months) or…

The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, "Student achievement in 2021-22: Cause for hope and continued urgency." The authors investigated two main research questions in this brief: (1) How do achievement gains…

Analysis of consistent Zearn Math users and a comparable group of non-users in District of Columbia Public Schools (DCPS) shows that students who used Zearn Math consistently had higher levels of academic growth than similar students with low- or no-usage. This analysis used two quasi-experimental methods, Coarsened Exact Matching (CEM) and fixed…

Double-dosing in math expands the time for students to learn by having them enroll in two (or occasionally more) math courses during the regular school day. Although the practice can take different forms and be used at different grade levels (Chait, Muller, Goldware, & Housman, 2007; Nomi & Allensworth, 2009), most research on…

The purpose of this technical appendix is to share detailed results and more fully describe the sample and methods used to produce the research brief, "COVID's Impact on Science Achievement: Trends from 2019 through 2024. We investigated three main research questions in this brief: 1) How did science achievement in 2021 and 2024 compare to…

The purpose of this study was to compare student growth of SCSD-7 students on the MAP (Measures of Academic Progress) reading assessment to otherwise similar students who did not use Istation. This study followed two cohorts of elementary school students over three years (2016-17 through 2018-19) to assess the effect of Istation on reading…

Contemporary state math standards emphasize that students must demonstrate an understanding of the mathematical ideas underlying the computations that have typically been the core of the elementary school math curriculum. The standards have put an increased emphasis on the study of fractions in upper elementary grades, which are the years during…

These are the appendixes for the report, "English Proficiency and the Pandemic: How Texas English Learner Students Fared during the COVID-19 Pandemic. REL 2023-144." This study examined levels of English proficiency before and during the COVID-19 pandemic among English learner students in grades 3-12 in Texas. In 2020-2021, nearly…

Does student-teacher match quality exist? Prior work has documented large disparities in teachers' impacts across student types but has not distinguished between sorting and causal effects as the drivers of these disparities. I propose a disparate value-added model and derive a novel measure of teacher quality--revealed comparative advantage--that…

The 2018 NSSME+ was based on a national probability sample of schools and computer science, mathematics, and science teachers in grades K-12 in the 50 states and the District of Columbia. The sample was designed to yield national estimates of course offerings and enrollment, teacher background preparation, textbook usage, instructional techniques,…

The Intercultural Development Research Association (IDRA) was awarded an Education Innovation and Research (EIR) Early Phase grant from the U.S. Department of Education in 2017 to develop, implement, and test a promising program to improve student achievement and educational progress for high-need students: Reenergizing Leadership to Achieve…

The project, "Oxford Improving Numeracy and Literacy Programme," was delivered by Oxford University Department of Education. This evaluation tested two different initiatives with Year 2 children: "Mathematics and Reasoning" and "Literacy and Morphemes." The "Mathematics and Reasoning" programme aimed to…
