When we administered the Test of Understanding of Vectors (TUV) to students who were completing a physics university remedial course (which covers subjects of a traditional high school physics course), we observed that they had considerable difficulties in interpreting the dot product as a projection. As a result of this, we decided to design a…

This quantitative study examined the effect of a student's entry point into a school district and his/her performance on the New York State English Language Arts and Integrated Algebras Regents Exams. The subjects of this study were students assigned to the 2010 and 2011 cohorts from one Long Island school district. Three entry points were…

This study examined the academic impact in reading and mathematics when Collaborative, Co-Teaching Team Model of high incidence special education student service delivery implemented in a suburban school district. This study hypothesized that the implementation of an inclusive collaborative co-teaching model of service delivery could possibly…

The goal of this study is to explore and characterize the effects of using a dynamic graphing utility (DGU) on conceptual understanding and attitudes toward mathematics, measured by the responses of college algebra students to an attitude survey and concepts assessment. Two sections of college algebra taught by the primary researcher are included…

The purpose of this quantitative, causal-comparative study was to compare the effect elementary music and visual arts lessons had on third through sixth grade standardized mathematics test scores. Inferential statistics were used to compare the differences between test scores of students who took in-school, elementary, music instruction during the…

Despite the growing popularity of diagnostic classification models (e.g., Rupp, Templin, & Henson, 2010) in educational and psychological measurement, methods for testing their absolute goodness-of-fit to real data remain relatively underdeveloped. For tests of reasonable length and for realistic sample size, full-information test statistics…

In this study we examined the effectiveness of a mobile game called MathDash for improving computational fluency as compared to a conventional drill and practice approach with computerized multiple-choice test items. An optical brain imaging method called functional near-infrared spectroscopy (fNIR) was utilized to assess changes in neural…

As states consider how their accountability systems will change under the Every Student Succeeds Act (ESSA), they face important decisions about which high school assessments to incorporate, what content their assessments will measure, which tests all students will take, and how rigorous those assessments will be. The purpose of this brief is to…

Academic preparedness, executive function abilities, and positive relationships with teachers have each been shown to be uniquely important for school readiness and success in the early elementary grades. Few studies, however, have examined the joint influence of these readiness variables on early school outcomes. Using data from a prospective…

This study aimed at (a) constructing a reliable and valid test to assess Ecuadorian 4-5-year olds' number and arithmetic skills; (b) providing empirical data on Ecuadorian 4-5-year olds' number and arithmetic skills; and (c) confronting these children's actual performances with the performances expected by national experts in this domain. We…

The purpose of this study was to examine how school schedules can or cannot be justified through the perspective of student performance on state core content assessments and occupational skills standards assessments. This study utilized the Theory of Power in Education when considering school schedules as a means to student success on core content…

Units of measure are critical in many scientific fields. While instructors often note that students struggle with units, little research has been conducted about the nature and extent of these difficulties or why they exist. We investigated calculus students' unit use in area and volume computations. Seventy-three percent of students gave…

Out-of-level testing refers to the practice of assessing a student with a test that is intended for students at a higher or lower grade level. Although the appropriateness of out-of-level testing for accountability purposes has been questioned by educators and policymakers, incorporating out-of-level items in formative assessments for accurate…

Research Findings: The focus of this study was to construct and validate 12 brief early numeracy assessment tasks that measure the skills and concepts identified as key to early mathematics development by the National Council of Teachers of Mathematics (2006) and the National Mathematics Advisory Panel (2008)-as well as critical developmental…

At the University of Louisville, a large, urban institution in the south-east United States, undergraduate engineering students take their mathematics courses from the school of engineering. In the fall of their freshman year, engineering students take "Engineering Analysis I," a calculus-based engineering analysis course. After the…
