The purpose of this quasi-experimental quantitative study was to determine whether the supplemental phonics program, Fundations, improved reading skills over time. Ehri's theory of orthographic mapping served as the theoretical framework for this study. Archival data from 254 second grade students who did, or did not, participate in the…

In-person tutoring has been shown to improve academic achievement. Though less well-researched, virtual tutoring has also shown a positive effect on achievement but has only been studied in grade five or above. We present findings from the first randomized controlled trial of virtual tutoring for young children (grades K-2). Students were assigned…

Most private schools in India follow the Alphabet-Spelling method to teach reading in English. This approach bypasses letter-sound correspondences and focuses on rote memorization and sight-word recognition. In an effort to provide students with more recent evidence-based practices in reading instruction, this study examined how phonics-based…

Identifying effective means of ameliorating achievement gaps and addressing literacy deficits is essential. Computer-assisted instruction (CAI) is one avenue for providing this effective instruction to the students that can most benefit from it. In the current study, kindergarten students in a public school district in Illinois received…

There were 42 Teach for America (TFA) members who had student schedules in both the October 2022 and February 2023 periods. Of those, 33 teachers instructed grades and subjects where students participated in the statewide assessment. The goal of this Research Brief is to estimate the instructional effectiveness of the TFA members in 2022-2023 as…

The universal role of phonological processing skills for reading acquisition has been established in many different languages including Arabic. However, in Arabic little knowledge exists about the development of wide-range of phonological tasks and about the correlations between them. We longitudinally studied the developmental trends and…

LXD Research analyzed data from 945 students in kindergarten who were Below or Well Below Benchmark at the beginning of the year and participated in using the Phonological Awareness (PA) Lessons Deluxe Package as an intervention in CA in Fall 2021. The product is a Tier 2 or Tier 3 intervention for grades K-2 that includes lessons and…

In this technical report, we present results of classification accuracy analyses to identify cut scores to optimize sensitivity and specificity for the easyCBM literacy assessments in Kindergarten through Grade 2. In conducting these analyses, we used the following approach: We kept sensitivity above 0.80 and maximized specificity from there. If…

The purpose of this study was to investigate Spanish-speaking multilingual learner (MLL) students' long-term academic outcomes after participation in an early childhood education (ECE) program with English instruction. The study included 359 Spanish-speaking MLLs who qualified for Free and Reduced Lunch from Grade 1 to Grade 6. Participants…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

This reports examines the Fall 2017 early reading performance of students who attended the Austin Independent School District's English learner summer school program in June 2017.

This project tested the effects of adding instruction of trios of children in patterning, mathematics, early literacy, or social studies to ongoing instruction in kindergartens. Children were randomly assigned to trios which were randomly assigned to one of four kinds of instruction. A quarter of the trios received patterning instruction with a…

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…

This study investigated the impact of a computer-adaptive reading program, Waterford Early Learning (WEL), in an elementary school in Indiana. The study investigated how educational technology, specifically computer-assisted instruction (CAI), would impact the literacy scores of kindergarten students when paired with traditional instruction:…

Recent work examining science test performance in the earliest grades of school has demonstrated that science test score gaps by race/ethnicity are apparent as early as kindergarten and that, in a number of cases, the racial/ethnic test score gaps in science are significantly larger than the corresponding gaps in reading or mathematics. This study…
