Many U.S. students possess only a weak knowledge of fraction arithmetic. I hypothesize that textbooks are a critical reason for students' poor performance on fraction arithmetic. This is not because of what textbooks contain but rather because of what they lack. Distributions of fraction arithmetic problems in textbooks are imbalanced, with…

This multi-method case study explored the actual and perceived mathematical growth, as measured by the counting and measuring, problem writing tasks (CaMPWTs) and focus student interviews respectively, of fifth graders at Catherine Elementary Middle School as they completed tasks designed specifically to scaffold the development of a set of math…

This study examined English as a foreign language (EFL) spelling development amongst 233 fifth-grade, eighth-grade and 10th-grade Hebrew first-language speakers to examine effects of English orthographic exposure on spelling. Good and poor speller differences were examined regarding the acquisition of novel phonemes (/ae/, /?/ and /?/) and…

This article uses a regression discontinuity approach to study the influence of New York City's school grading policy on student math and English language arts (ELA) achievement. We find evidence that students in schools receiving a failing grade realized positive effects in English in the 1st year of sanction, but we find no statistically…

In this paper, we present a closer look at the student achievement trends in the District of Columbia between 2006-07 and 2012-13. We have three main conclusions. First, we find that overall, math scores in the District have improved. The improvements in reading scores during this time frame, however, were primarily limited to the first year after…

The Massachusetts Expanded Learning Time (ELT) initiative was established in 2005 with planning grants that allowed a limited number of schools to explore a redesign of their respective schedules and add time to their day or year. Participating schools are required to expand learning time by at least 300 hours per academic year to improve student…

Community schools are an approach that has been adopted to respond to this educational crisis. By partnering with local agencies, community schools provide students and families with access to healthcare services, educational enhancement and recreational opportunities, family economic supports such as workforce development and income tax…
