On average, Florida students earn only half of the points possible in the statistics content area of the state's annual mathematics assessment. Leaders in Broward County Public Schools, a large, diverse, urban school district, viewed changes to statistics curriculum and instruction as one way to address this issue. This study randomly assigned 40…

Broward County Public Schools (BCPS) has identified low student achievement in statistics in the middle grades as a critical concern. It has also expressed concern that statistics instruction does not meet the level of cognitive complexity described in the state curriculum standards. This randomized controlled trial in 40 BCPS middle schools…

These are the appendixes for the report "Effects of an Inquiry-Oriented Curriculum and Professional Development Program on Grade 7 Students' Understanding of Statistics and on Statistics Instruction." This cluster-randomized controlled trial compared the Supporting Teacher Enactment of the Probability and Statistics Standards (STEPSS)…

This study examined the heterogeneity of literacy profiles for adolescents with and without a specific learning disability (SLD) in the U.S. state of Florida Student subgroups displaying common patterns of performance in word-level skills and reading comprehension were identified through latent profile analysis. Results indicate most of the total…

This study aimed to describe 1-year changes in students' vocabulary in written narratives. Secondary aims included examination of accuracy and the relationship between lexical diversity and achievement. Participants included 749 students in first through eighth grades. Within-subjects 1-year change in diversity, productivity, and accuracy was…

This investigation examined the structural relations among latent variables of language, decoding, and reading comprehension, invariance of the patterns of predictions, and unique and common variance over two years in grade cohorts 5 to 6, 7 to 8, and 9 to 10. Participants were 321 students in grade 5 in six elementary schools, 299 students in…

Academic discourse communities and learning circles are characterized by collaboration, sharing commonalities in terms of social interactions and language. The discourse of these communities is composed of jargon, common terminologies, and similarities in how they construe and communicate meaning. This study examines the extent to which discourse…

Educators, researchers, and policy makers concerned about college under-enrollment among underserved groups of students have traditionally focused reform efforts at the high school level. Over the last several decades, however, there has been a growing interest in improving college readiness beginning at the elementary level. Recently, the…

Adolescents' attitudes predict sexual behavior; therefore, attitudes are targeted in sexually transmitted infection (STI) and pregnancy prevention programs. However, attitudes and behaviors do not always align. Young adolescents who have had penile vaginal intercourse (PVI) and have attitudes supportive of PVI have two risk factors for future…

We study the usage of a self-guided online tutoring platform called Algebra Nation, which is widely by middle school and high school students who take the End-of-Course Algebra I exam at the end of the school year. This article aims to study how the platform contributes to increasing students' exam scores by examining users' logs over a three year…

In a typical mathematics course, the material is divided into many lessons, and each lesson is followed by an assignment consisting of practice problems. Most commonly, each assignment consists solely of problems on the preceding lesson. For example, a lesson on ratios might be followed by an assignment with 12 problems on ratios. In other words,…

Large numbers of qualified students do not apply to and enroll in college. Yet, earning a college degree is one of the primary pathways for economic success and is increasingly required for good jobs and high wages. A number of programs and practices aim to improve college readiness and enrollment, including "Take Stock in Children's®…

Researchers attempting to show that music has positive effects on children need to understand and control for preexisting differences between those who do and do not select into musical participation in the first place. Within a large-scale, communitywide, prospective, longitudinal study of predominantly low-income, ethnically diverse students (N…

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…
