LXD Research was engaged by 95 Percent Group to conduct a third-party, mixed-methods efficacy study of their 95 Phonics Core Program (95 PCP) to evaluate the impact on fourth and fifth grade literacy outcomes over the school year 2023-2024. LXD analyzed the formative assessment data from i-Ready, focusing on overall scale scores, subdomains, and…

The purpose of this study is to analyze discipline based art education and choice based art education. Discipline based art education is a teacher directed approach and choice based art education is a student centered approach. During the study I implemented these two teaching/learning approaches, collected and analyzed data, and reported the…

Saint Edmond's Academy is a small, independent, Catholic school in Wilmington, Delaware. Students in Grades 4 to 7 are falling below their peers in other independent schools on standardized tests in mathematics, specifically the Educational Advisory Company Comprehensive Testing Program assessment. Within the scope of this work, my goal was to…

This study investigated the accuracy of three fraction measures (i.e., fraction number line estimation accuracy, general fraction concepts, and fraction arithmetic) for screening fourth graders who might be at risk for mathematics difficulties. Receiver operating characteristic (ROC) curve analyses assessed diagnostic accuracy of the fraction…

This chapter situates fraction learning within the integrated theory of numerical development. We argue that the understanding of numerical magnitudes for whole numbers as well as for fractions is critical to fraction learning in particular and mathematics achievement more generally. Results from the Delaware Longitudinal Study, which examined…

Third grade is a critical checkpoint in a child's educational journey. By the end of third grade, children need literacy skills that prepare them for increasing curriculum demands in fourth grade and beyond. Students who are not reading on grade level by this point are significantly more likely to drop out of high school or fail to graduate on…

The goal of the present article is to synthesize findings to date from the Delaware Longitudinal Study of Fraction Learning. The study followed a large cohort of children (N = 536) between Grades 3 and 6. The findings showed that many students, especially those with diagnosed learning disabilities, made minimal growth in fraction knowledge and…

This mixed-methods study was designed to understand the perceptions of K-5 elementary educators in regard to social studies, methods of instruction, and the amount of instructional time spent on social studies in relation to other core subjects. The descriptive study utilized a cross-sectional survey design to understand the perceptions of 153 K-5…

"Odyssey® Math" is a web-based program developed by Compass Learning® for mathematics instruction in grades K-8. The online program includes a mathematics curriculum and formative assessments designed to support differentiated and data-driven instruction. Based on assessment results, the program generates an individualized sequence of…

Business leaders in Delaware cannot find the science, technology, engineering and mathematics (STEM) talent they need to stay competitive. Students' lagging performance in K-12 is a critical reason why. The good news is that the nation's most effective STEM education programs can help turn the tide. Delaware students have already made real…

The study featured in this What Works Clearinghouse (WWC) Quick Review examined whether exposure to "Odyssey[R] Math," a web-based mathematics curriculum and assessment tool, improved mathematics achievement of fourth-grade students. The study analyzed data from 2,456 fourth-grade students in 122 classrooms in 32 elementary schools in…

Prevalence rates for bullying victimization among children with disabilities have varied greatly in the research literature. Two reasons for such variability were the focus of this study: (a) rates vary as a function of disability type, and (b) rates vary based on the bullying measure and criteria used to classify students as bullying victims. The…

The purpose of the present study was to reveal the developmental pathway from third grade cognitive competencies to sixth grade conceptual and procedural fraction knowledge through the intervening whole numerical skills at fifth grade. The study used empirical data that come from 536 students in nine schools across two Delaware public school…

Developmental predictors of children's fraction concepts and procedures at the end of fourth grade were investigated in a 2-year longitudinal study. Participants were 357 children who started the study in third grade. Attentive behavior, language, nonverbal reasoning, number line estimation, calculation fluency, and reading fluency each…

The purpose of this study was to identify the impact the Girls on the Run (GOTR) program had on the New Castle County, Delaware, third, fourth, and fifth grade girls who participated in the spring 2011 season. Specifically, this study examined short-term changes in the participants as they related to self-esteem, body image, physical activity…
