Background: Acute physical activity breaks lasting 10--60 min have been related to positive effects on student focus and academic performance. The aim of this study was to evaluate the impact of repeated brief physical activity-infused academic lessons (1-5 min) on student retention and on-task behavior. Methods: One class from each K-2 grade…

Non-formal education (NFE) has a role to play in the education of marginalised groups such as out-of-school adults. NFE is based in the discourse of lifelong learning with its agenda of economic growth and active citizenship. This discourse requires moving beyond traditional conceptualisations of primary, secondary and tertiary education to…

Background: Obstructive sleep apnea (OSA) is chronic disorder that contributes to multiple physiological and psychological conditions. Obstructive sleep apnea contributes to high rates of morbidity and mortality and has substantial impacts on both health care costs and the quality of life for affected individuals and their families. Healthcare…

The majority of studies examining the language and literacy skills of second generation immigrant bilingual children have focused on the breadth of lexical knowledge in populations with a low level of involvement in literacy activities. This study extends previous work in three ways. First, we focused on a sample of second generation immigrant…

This survey study investigated the effects of the National Association of School Psychologists PREPaRE Workshop 2 training on workshop participants. PREPaRE is a comprehensive crisis prevention and intervention model that is specifically designed for schools. This study evaluated the impact of the PREPaRE model and the training of school…

In 2007, Lisa Carter created the Total Instructional Alignment system--a process that aligns standards, curriculum, assessment, and instruction. Employed in several hundred school systems, the TIA process is a successful professional development program. The researcher developed an instrument to measure the success of the TIA process with the…

Possessing sufficient nutritional knowledge is a necessary component in the prevention and treatment of obesity. A solid understanding of nutrition can help people make appropriate food selections and can also help correct irrational ideas or myths people may believe about food. It is a challenge to provide this information to children in ways…

Understanding an arithmetic operation implies, at minimum, knowing the direction of effects that the operation produces. However, many children and adults, even those who execute arithmetic procedures correctly, may lack this knowledge on some operations and types of numbers. To test this hypothesis, we presented preservice teachers (Study 1),…

Educators often use manipulatives when teaching mathematics because manipulatives are assumed to promote learning. However, research indicates that instructional variables impact the effectiveness of manipulatives. In this article, the authors consider the relations between two instructional characteristics: (a) level of instructional guidance and…

The main objective of this study was to investigate empirically if promoting a multimedia package enhances content knowledge in essay writing of 80 junior English translation students at a University in Karaj, Iran; plus, whether the learners' writing content improve due to the presence of the multimedia package or not.

We compared 5 different statistics (i.e., G index, gamma, "d'", sensitivity, specificity) used in the social sciences and medical diagnosis literatures to assess calibration accuracy in order to examine the relationship among them and to explore whether one statistic provided a best fitting general measure of accuracy. College…

In this study, a progressive-learning approach to physics, based on knowledge-building pedagogy, was compared to a content-centered approach in which explanations, experiments, and discussions are centered on the transmission of knowledge. Forty-six students attending the first year of high school participated in this study over a whole school…

Science education researchers recently turned their attention to exploring views about nature of science (NOS). A large body of research indicates that both students and teachers have many naïve views about the NOS. Unfortunately, less attention has been directed at the issue of exploring the views of the scientists. Also, the little research in…

This study examines the relative instructional efficiency of virtual and physical fraction manipulatives. More specifically, this study uses a randomized experiment to determine if differences in students' knowledge of fractions magnitude exist when students use virtual rather than physical manipulatives to learn basic fraction concepts.…

This study investigated whether and, if so, how metacognitive knowledge can be assessed validly in students with special educational needs in a large-scale assessment like the German National Educational Panel Study. In total, 804 sixth-grade students including both regular school students attending the lowest track of secondary education…
