Research shows that assuming a test scale is equal-interval can be problematic, especially when the assessment is being used to achieve a policy aim like evaluating growth over time. However, little research considers whether teacher value added is sensitive to the underlying test scale, and in particular whether treating an ordinal scale as…

This teaching experiment provided students with continuous engagement in a problem-solving based instructional approach during one mathematics unit. Three sections of sixth-grade mathematics were sampled from a school in Florida, U.S.A. and one section was randomly assigned to experience teaching through problem solving. Students' problem-solving…

The purpose of this study was to determine the effectiveness of an instructional package, Self-Regulated Strategy Development, a cognitive strategy instructional model (POW + TREE), in combination with video self-modeling (VSM) on the improvement on the written expression of three third-grade students with learning disabilities (LD). This…

This study defines subpopulation item parameter drift (SIPD) as a change in item parameters over time that is dependent on subpopulations of examinees, and hypothesizes that the presence of SIPD in anchor items is associated with bias and/or lack of invariance in three psychometric outcomes. Results show that SIPD in anchor items is associated…

In this study, we compare the teacher quality distributions in charter schools and traditional public schools, and examine mechanisms that might explain cross-sector differences in teacher effectiveness as measured by teacher value-added scores using school and teacher level data from Florida. We have three main findings. First, we find that…

Underachievement among gifted students is a paradox that frustrates educators because of the significant disparity between students' potential and their performance. Complicating the issue is the highly individualized nature of the underperformance, which must take into consideration factors of student culture, socio-economic status, motivation,…

A typical mathematics assignment consists primarily of practice problems requiring the strategy introduced in the immediately preceding lesson (e.g., a dozen problems that are solved by using the Pythagorean theorem). This means that students know which strategy is needed to solve each problem before they read the problem. In an alternative…

This empirical mixed methods study examines educators' understandings of student risk factors. The research was conducted in a Title 1 combination middle high school in the Florida panhandle that had been open for three years and had received a grade of F school in each of these years. In Florida, schools are graded according to the Florida…

Randomized experiments are often considered the strongest designs to study the impact of educational interventions. Perhaps the most prevalent class of designs used in large scale education experiments is the cluster randomized design in which entire schools are assigned to treatments. In cluster randomized trials (CRTs) that assign schools to…

This case study conducted with 1,425 middle school students in Palm Beach County, Florida, included a treatment group receiving GIS instruction (256) and a control group without GIS instruction (1,169). Quantitative analyses on standardized test scores indicated that inclusion of GIS in middle school curriculum had a significant effect on student…

In this mixed method research, we examined the effects of reading and singing software program (RSSP) as a reading intervention on struggling readers' reading achievement as measured by the Florida Comprehensive Assessment Test, the high stakes state test administered in the state of Florida, at one elementary school. Our team defined struggling…

When lotteries are infeasible, researchers must rely on observational methods to estimate charter effectiveness at raising student test scores. Considerable attention has been paid to observational studies by the Stanford Center for Research on Education Outcomes (CREDO), which have analyzed charter performance in 27 states. However, the…

Previous research has demonstrated a correlation between student demographic factors and standardized test scores in Florida. The researcher examined the impact teacher beliefs and instructional practices had on students' performance on Florida Comprehensive Reading Assessment Test in 10th grade. Teachers at four schools with a majority of at-risk…

This study focuses on three case studies of three Florida teachers' action research projects focusing on improving at-risk students' literacy skills through innovative instructional technology, culturally-relevant poetry and bilingual teaching. The teachers, White, African American and Latina, describe their research journeys, the literacy…

Singing exaggerates the language of reading. The students find their voices in the rhythm and bounce of language by using music as an alternative technological approach to reading. A concurrent mixed methods study was conducted to investigate the use of an interactive sing-to-read program Tune Into Reading (Electronic Learning Products, 2006)…
