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,…

The purpose of this study was to examine African American and Latino student perceptions on test-centered curricular protocols in the urban high school context. Data collection occurred through observations, classroom dialogue initiated by the researchers, and individual student interviews throughout an academic semester. Findings suggest that…

Expansion of the use of student test score data to measure teacher performance has fueled recent policy interest in using those data to measure the effects of school administrators as well. However, little research has considered the capacity of student performance data to uncover principal effects. Filling this gap, this article identifies…

Evidence that teachers' short-term instructional effects persist over time and predict substantial long-run impacts on students' lives provides much of the impetus for a wide range of educational reforms focused on identifying and responding to differences in teachers' value-added to student learning. However, relatively little research has…

Although prior research has documented differences in the distribution of teacher characteristics across schools serving different student populations, few studies have examined the extent to which teacher sorting occurs within schools. This study uses data from one large urban school district and compares the class assignments of teachers who…

A phenomenological case study by Counsell (2007) explored and investigated the phenomenon of what happened as Florida's A+ Plan intersected with the life histories of one beginning African American female third grade teacher and one veteran White female third grade teacher at demographically different school communities in one Florida school…

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 study examined achievement gains in reading and math for Hispanic middle school students with specific learning disabilities in inclusive versus segregated settings in a large urban school district. The authors report learning gains for students with and without disabilities in inclusive versus segregated settings. Results indicate no…

The purpose of this study was to examine the effects of a Tier 2 supplemental intervention focused on rational number equivalency concepts and applications on the mathematics performance of third-grade students with and without mathematics difficulties. The researcher used a pretest-posttest control group design and random assignment of 19…

Scholars have long argued that principals should be "instructional leaders," but few studies have empirically linked specific instructional leadership behaviors to school performance. This study examines the associations between leadership behaviors and student achievement gains using a unique data source: in-person, full-day…

This study investigated the impact of a range of variables as predictors of graduation potential for students with Specific Learning Disabilities (SLD) or Emotional Behavioral Disorders (EBD) within a large urban school district. These factors included the following characteristics and elements: (a) primary exceptionality, (b) gender, (c)…

The authors' purpose was to explore the effects of a supplementary, guided, silent reading intervention with 80 struggling third-grade readers who were retained at grade level as a result of poor performance on the reading portion of a criterion referenced state assessment. The students were distributed in 11 elementary schools in a large, urban…

Math Snacks animations and support materials were developed for use on the web and mobile technologies to teach ratio, proportion, scale factor, and number line concepts using a multi-modal approach. Included in Math Snacks are: Animations which promote the visualization of a concept image; written lessons which provide cognitive complexity for…

In this article, the author discusses the intensive support given to some of the lowest-performing schools in the Miami-Dade County, Florida. One of these schools is Miami Jackson High School, one of Florida's worst-performing schools. For two of the last three years, it has brought its state grade up from an F to a D. But now the initiative,…
