The goal of Smithsonian Science for North and South Carolina Classrooms was to provide teachers with ongoing, differentiated professional development and research-based curricular materials to improve elementary student achievement in science, mathematics, and reading. This work used an inquiry-based science curriculum, Smithsonian Science for the…

The purpose of this quantitative, ex post facto study was to determine the difference in students' LEAP ELA achievement scores in grades 3-5 based on the teacher's level of dyslexia knowledge. This study used the Phonological Deficit Theory (PDT) and the Criterion Referenced Assessment Theory (CRT) as its foundation. PDT describes the levels of…

Standardized testing is generally regarded in schools today as the primary way to measure and determine student achievement. Student performance determines the degree to which schools, teachers, and students are identified as being successful. The problem being investigated by this study was that all students are spending too much classroom…

The problem addressed in this study was that in response to low standardized test scores, instructional strategies were required to be implemented in English Language Arts (ELA), but teachers in Grades 1 through 5 in the study site experienced challenges using these strategies to meet student learning needs. The explored teachers' experiences and…

As result of several federal policies over the last few decades, accountability measures for student learning and success have increased tremendously. Therefore, many school districts, including East Tennessee School District which was the subject of this study, implemented district-wide benchmark testing such as the Collaborative Assessment…

The Conover Solution is a nonparametric method used to analyze relative growth in students' achievement on state tests administered on two or more occasions. However, there has been very little research assessing the robustness of this method in the presence of missing data. Using vertically scaled and non-vertically scaled data from the math…

School closures due to the COVID-19 pandemic raised concerns about increases in educational inequality. We examined the magnitude of the impact of the first school closure for vulnerable student groups in particular. This study was conducted among 886 Grade 3-5 students in the Netherlands in schools serving a high percentage of students from…

Math programming that includes assessments to predict standardized mathematics scores can help evaluate student performance and growth during the academic year. ACALETICS® is a highly interactive, culturally inclusive mathematics program that utilizes posttests as continuous comprehensive assessments to evaluate student mathematical knowledge.…

The topic for this dissertation was the effects arts have on standardized test scores of math. The research problem compared the students who had fine arts integrated into the curriculum and those that did not. This study included six target schools that have primarily African American students. The six-city schools studied were the third through…

This study details the quantitative impact of educator leadership on student achievement outcomes for over 9,200 students in 398 fourth, fifth, and sixth grade classrooms within the Chula Vista Elementary School District, across 44 schools. Although the phenomenon of teacher leadership has been the subject of qualitative research for many decades,…

This article contributes to the larger narrative around what makes a mathematics professional development (PD) successful and in what ways. We share a research-based PD model that was implemented in elementary schools in an urban school district for 3 years. The model uses a pseudo lesson study approach and emphasizes standards-based instruction.…

Research suggests that executive function, motivation, transcription, and composition processes are implicated in the writing quality and productivity of children with and without learning difficulties. However, numerous components embedded within these constructs create both conceptual and empirical challenges to the study of written expression.…

Purpose: A growing trend in instructional improvement efforts is the use of formative assessment informed by research-based developmental trajectories of how students gain deeper understanding of subject matter content over time. This article reports the findings of a large-scale experimental study of an innovative mathematics professional…

Background: Over the last twenty years, retention has increased in popularity with policymakers who are concerned with student achievement and aim to end social promotion (i.e., the practice of advancing a student to the next grade level although they have not yet met the academic expectations of their current grade level). Despite calls to expand…

Four-parameter models have received increasing psychometric attention in recent years, as a reduced upper asymptote for item characteristic curves can be appealing for measurement applications such as adaptive testing and person-fit assessment. However, applications can be challenging due to the large number of parameters in the model. In this…
