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,…

In this study, the factorial invariance of the ASIS (Anadolu-Sak Intelligence Scale) was examined across time. Data were obtained from there groups of first-grade students who were administered the ASIS in 2020, 2021, and 2022. The analyses were conducted using multisample confirmatory factor analyses. Factorial invariance was tested with six…

This study investigated the effect of the motor game 'Exchequer Motor Game' (EMG) on first-grade children's Level of Geometric Thinking (LGT) and their post-learning mood tracking (PLMT). Thirty children (age 6.1 ± 0.7 years; physical education experience: 0.6 ± 0.4 years), classified at the "Visualization" stage of van Hiele's geometric…

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…

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…

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…

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…

There is considerable variability in the literacy assessments taken in Kindergarten through second grade, across schools and between multilingual learners and other students, and within students over time. This makes it difficult to study changes in students' acquisition of ELA skills in these formative years, or to evaluate policies and practices…

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…

This quantitative, causal-comparative research study investigated whether school configuration has an impact on the reading performance of sixth-grade students by comparing the End-of-Grade (EOG) reading assessment Grade Level Proficiency (GLP) scores of sixth-grade students in K-8 configured schools to sixth-grade students enrolled in 6-8 grade…

This study compared students' performance on Istation, a computer-based progress-monitoring tool, and easyCBM, a paper-pencil progress-monitoring tool. Participants included 106 students in Grades K-6 from a rural school in New Mexico. Teachers in these grade levels administered both assessments three times during the school year. Results…

This report describes the impact of the 2021 AISD multilingual summer school program on incoming kindergarten and 1st-grade emergent bilingual students' (N = 933) fall academic performance. Relative to matched comparison groups, students who attended summer school were significantly more likely to score on-track on TX-KEA in kindergarten. While…
