The aim of this longitudinal research is to examine the development process of scientific and consistent knowledge structures of first, second, and third-grade students in middle school within the concepts of melting and dissolution according to conceptual change theories at the end of the education and training processes carried out in…

Purpose: Previous studies examining the inter-relations between serial and discrete naming with reading have found that the ability to efficiently process multiple items presented in a sequence (indexed by serial naming) is a unique predictor of word- and text-reading fluency. However, conclusions have been tempered by the concurrent nature of the…

Math achievement is an important predictor of progression to later science, technology, engineering, and math (STEM) education and careers. However, attitudinal factors also play a role, and interventions attempting to improve math attitudes may be important for increasing the number of STEM-aspiring students. To design effective interventions, it…

Longitudinal models of individual growth typically emphasize between-person predictors of change but ignore how growth may vary "within" persons because each person contributes only one point at each time to the model. In contrast, modeling growth with multi-item assessments allows evaluation of how relative item performance may shift…

Longitudinal models typically emphasize between-person predictors of change but ignore how growth varies "within" persons because each person contributes only one data point at each time. In contrast, modeling growth with multi-item assessments allows evaluation of how relative item performance may shift over time. While traditionally…

The problem addressed in the study is the significant numbers of elementary school students who fail to demonstrate proficiency in reading/language arts as determined by the Georgia Milestones English Language Arts Test. The purpose of this basic qualitative study was to investigate teachers' perceptions of effective research-based parental…

The goal of this study was to evaluate the impact of IXL on early literacy development, as measured by the Star Early Literacy Assessment. Using a pretest-posttest design, we analyzed data from 2,959 kindergarten through 3rd-grade students in an Oklahoma school district during the 2021-22 school year. We found positive and statistically…

This study explored the role of growth in the executive components of working memory (WM) on second language (L2) mathematical problem-solving in elementary school children who are emerging bilinguals whose first language (L1) is Spanish. To this end, children (N = 429) in Grades 1, 2, and 3 at Wave 1 were administered a battery of math, reading,…

This study examined the impact of a commonly adopted elementary universal social-emotional learning program, Second Step, on student social-emotional and academic outcomes following 2 years of implementation. The cluster-randomized wait-list control trial included 61 schools, 321 teachers, and 8,941 early elementary students across 2 states, with…

The authors investigated the differential effect of retention on the development of academic achievement from grades 1 to 5 on children retained in grade 1 over 6 years. Growth mixture model (GMM) analyses supported the existence of two distinct trajectory groups of retained children for both reading and math among 125 ethnically and…

This randomized controlled field trial examined the efficacy of the Responsive Classroom (RC) approach on student achievement. Schools (n = 24) were randomized into intervention and control conditions; 2,904 children were studied from end of second to fifth grade. Students at schools assigned to the RC condition did not outperform students at…

This exploratory study examined the contribution of the "RC" Approach over a two-year period. The "RC" Approach integrates social and academic learning in order to produce classroom environments that are conducive to learning by integrating social and academic learning. Two questions are addressed. First, how does teachers' use of "RC" practices…
