When classroom observations are increasingly used for accountability and evaluation purposes, a deeper understanding of the psychometric properties of such measurement tools is needed. The present study took a unique approach to examine the psychometric properties of a commonly used classroom observation measure by testing the reliability of…

LXD Research conducted a study to evaluate the impact of the Zaner-Bloser Kickstart: Number Sense program, a math intervention designed to enhance foundational math skills among first and second-grade students in an Oregon school district over a three-year period from spring 2019 to Spring 2023. The program was implemented in two schools, engaging…

This study utilized a partially nested randomized control design to investigate the impact of Fusion, a first-grade math intervention. Blocking on classrooms, students were randomly assigned to one of the three conditions: a Fusion two-student group, a Fusion five student group, or a no-treatment control group. Two primary research questions were…

This study utilized a partially nested randomized control design to investigate the impact of Fusion, a first grade math intervention. Blocking on classrooms, students were randomly assigned to one of three conditions: a Fusion two student group, a Fusion five student group, or a no treatment control group. Two primary research questions were…

Running Records provide a standardized method for recording and assessing students' oral reading behaviors and are excellent formative assessment tools to guide instructional decision-making. This study expands on prior Running Record reliability work by evaluating the extent to which external raters and teachers consistently assessed students'…

The purpose of this mixed methods study was to determine the effects of a tutorial program on first-grade children's reading skills and their tutors' (also preservice teachers) knowledge of reading instruction. Participants consisted of a group of 30 first-grade children served in the program and a control group of 30 children. Literacy…

To investigate whether child × instruction effects contribute to mathematics gains in first grade, we conducted a cluster randomized controlled trial with 454 (205 treatment; 249 control) students in 28 classrooms. Classrooms were randomly assigned to implement Math Peer Assisted Learning Strategies (Math PALS) to supplement Saxon Math or Saxon…

The Flynn effect, which advocated that there was a rise in the global IQ score, was widely accepted by the relevant scientific community. However, there are recent research findings that this effect has been reversed. In this study, both Flynn and anti-Flynn effects were investigated. The purpose of this study is to analyze students' general,…

Early literacy proficiency is a crucial predictor of later reading success, but research in this area often overlooks the unique challenges faced by English Learners (EL). This study addressed a significant gap in the literature by investigating the relationships between Dynamic Indicators of Basic Early Literacy Skills (DIBELS) scores, English…

This study used hierarchical linear modeling to examine the relationship between an internet-based mathematics formative assessment and data from a mathematics summative assessment for primary grade learners (ages 5-7). Results showed a positive relationship between formative assessment data related to the concepts of counting and decomposing…

Students who receive English Learner (EL) services at Forest Oak Elementary School in Newark, Delaware, do so through a pull-out model of instruction. They meet with an EL coach in a separate setting for instruction on reading, writing, speaking, and listening in English. A first-grade teacher at Forest Oak Elementary School participated in this…

Genetic studies show that children's reading achievement is in part genetically influenced, and intervention studies show that reading achievement can be increased by environmental interventions. However, correlational and mean-level analytic strategies are rarely integrated into achievement research, potentially leading to misinterpretation of…

State legislators recognized that students in the United States continue to struggle with reading and have begun implementing laws requiring schools to use science of reading-aligned curriculum when teaching reading (Schwartz, 2022). Many students lack the foundational skills to even begin learning how to read in grades K-3 (Kuhfeld et al., 2022).…

There is no final consensus regarding which covariates should be used (in addition to prior achievement) when estimating value-added (VA) scores to evaluate a school's effectiveness. Therefore, we examined the sensitivity of evaluations of schools' effectiveness in math and language achievement to covariate selection in the applied VA model. Four…

Social capital is widely cited as benefiting children's school performance, but close inspection of existing research yields inconsistent findings. Focusing on intergenerational closure among parents of children in the same school, this article draws from a field experiment to test the effects of social capital on children's achievement in reading…
