Schools need evidence-based guidance on which measures in mathematics, administered under what particular set of conditions (e.g., time of year), provide the most useful prediction. The purpose of this study was to examine decision accuracy among commonly used screening measures with a priority toward identifying the least costly screening…

Background: Cluster randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

This study investigated longitudinal pathways leading from early spatial skills in first-grade girls to their fifth-grade analytical math reasoning abilities (N = 138). First-grade assessments included spatial skills, verbal skills, addition/subtraction skills, and frequency of choice of a decomposition or retrieval strategy on the…

Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

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…

This case study addresses two major priorities of the Boston Foundation--health and education. Since the 2007 publication of the "Understanding Boston" report "The Boston Paradox: Lots of Health Care, Not Enough Health," the Boston Foundation has worked to draw attention to the epidemic of preventable chronic disease that not…

This brief describes a quasi-experimental study of Word Generation, conducted in public middle schools in Boston. Word Generation is a robust vocabulary intervention that is implemented across key subject areas. The purpose of the program is to enhance students' vocabulary in support of improved reading comprehension. The brief outlines the…

"Identifying Success in Schools and Programs for English Language Learners in Boston Public Schools," of which this report is one part, is a project commissioned by the Boston Public Schools as part of this process of change set in motion by the intervention of the state and the federal governments on behalf of Boston's English language…

English language learners (ELLs), their teachers, and the schools and programs where they are enrolled face a triple challenge: (1) students must be taught and learn English at a level of proficiency high enough to allow them access to academic content; (2) students must be taught and learn academic content at a level comparable to that of English…

This pamphlet explains a child's Massachusetts Comprehensive Assessment System (MCAS) "Student Report for Parents/Guardians." In spring 1999, more than 210,000 students from grades 4, 8, and 10 in Massachusetts took the state's MCAS tests. All public students in grades 4, 8, and 10 are required to participate, and the Education Reform…

The Second International Conference on Educational Data Mining (EDM2009) was held at the University of Cordoba, Spain, on July 1-3, 2009. EDM brings together researchers from computer science, education, psychology, psychometrics, and statistics to analyze large data sets to answer educational research questions. The increase in instrumented…
