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…

Early detection of and relevant information on children's mathematical difficulties is important to initiate targeted teaching and intervention. This study investigated the extent to which strategy use in single-digit addition provides additional predictive information about 61 grade one children's (6-year-old) mathematical achievement 3 years…

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…

Over the last 62 years, mathematics reform has occurred due to a political push after results from a major survey or report were released stating that the United States scored lower than other countries. With each reform effort, teaching methods were changed to match the new initiative. Math curriculum was a key point in each of these reform…

Purpose: The purpose of this journal-ready dissertation was to determine the degree to which enrollment in a Title I, Part A school was related to the reading performance of Grade 4 students on the Texas state-mandated reading assessment. Specifically examined was the extent to which boys and girls enrolled in Title I, Part A schools and non-Title…

Linking score scales across different tests is considered speculative and fraught, even at the aggregate level. We introduce and illustrate validation methods for aggregate linkages, using the challenge of linking U.S. school district average test scores across states as a motivating example. We show that aggregate linkages can be validated both…

The purpose of this research was to examine the relationship between State of Texas Assessments of Academic Readiness (STAAR) reading and academic progress in the programs of Istation and Star Renaissance (Star Ren) in fourth grade special education students. Special education students in the selected school district appear to produce inconsistent…

Academic achievement and absenteeism are two areas that schools are held accountable. Helping families and communities understand the correlation between achievement and attendance is an essential part of improving attendance. The purpose of this research study was to compare student attendance and academic achievement on the CASE Benchmark exams…

The purpose of this quantitative study was to examine whether English as a Second Language (ESL) Hispanic students, attendance at Title I or Non-Title I schools, and percentage of Bilingual/ESL teachers on campus impacted academic performance as measured by standardized tests. With a rapidly expanding Hispanic population in Texas, it was prudent…

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…

Cheating detection is an important issue in standardized testing, especially in large-scale settings. Statistical approaches are often computationally intensive and require specialised software to conduct. We present a two-stage approach that quickly filters suspected groups using statistical testing on an IRT-based answer-copying index. We also…

National, state, and local governmental authorities have researched and reported the impacts of poverty on academic performance for multiple decades, providing guidance, legislation, accountability, equal access initiatives, and continuous monitoring for educators to address the ongoing dilemma. However, poverty performance achievement gaps are…

The focus on STEM has centered on knowledge use across multiple disciplines. However, there currently exists limited understanding of the relationship between the cognitive practices utilized across these disciplines as a function of performance on standardized assessments. Focusing on science and mathematics, we investigated the direct and…

After the passage of "No Child Left Behind," and especially after Obama-era Race to the Top initiatives, rising accountability for improved achievement and widespread dissatisfaction with the instructional value of statewide test reports led many school districts to purchase computer-adaptive "interim" testing systems. A common…

Meeting standardized test benchmarks is a challenge for elementary school students in Texas. The problem is that some elementary schools do not meet the performance standards of the fourth-grade STAAR state test average. Problem-based learning is a model used in schools to initiate problem-solving skills with a hands-on approach to real-world…
