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…

The purpose of this study is to investigate the effects of a ubiquitous problem-based learning system (UPBLS) on students' question-raising performance in field inquiry activities. An experiment was conducted on an elementary school natural science course. A total of 43 sixth and fifth grade elementary students divided into experienced and…

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…

Our research was oriented to test the effects of a structured program of cooperative learning in Physical Education classes with students in grades 5 and 6 of primary school, with and without previous experience with this methodology. In a second phase we sought to determine how students perceived the received classes for a time later. We analysed…

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…

Most growth models implicitly assume that test scores have been vertically scaled. What may not be widely appreciated are the different choices that must be made when creating a vertical score scale. In this paper empirical patterns of growth in student achievement are compared as a function of different approaches to creating a vertical scale.…

This investigation examined the effects of currently available word prediction software programs that support phonetic/inventive spelling on the quality of journal writing by six students with severe writing and/or spelling difficulties in grades three through six during a month-long summer writing program. A changing conditions single-subject…

The present study examined outcomes on the Tennessee Comprehensive Assessment Program/Achievement Test (TCAP/AT) for the KIPP:DIAMOND Academy (KIPP:DA), which is in its second year of operation. Importantly, as in Year 1, a rigorous quasi-experimental research design was employed, in which each KIPP:DA student was individually matched to a highly…
