Phenomenological Study Of The Significance Of Recess And Brain Breaks During The Instructional Day From The Perspective Of Elementary Teachers, Laura Knight
Doctoral Dissertations and Projects
The purpose of this phenomenological qualitative study was to collect the perceptions of elementary teachers on the influence of recess and brain breaks on students within the instructional day capturing the essence of their voice through analysis. Participants included 10 teachers at Smith School District (pseudonym used) in the southeastern United States of America. One of the theories guiding this study was Maslow’s Hierarchy of Needs (Maslow, 1954) as it was in question whether elementary teachers perceive that students must have their need for physical movement met in order for optimal learning to occur. Another theory guiding this study was …

Background: Use of mobile (MP) and cordless phones (CP) is common among young children, but whether the resulting radiofrequency exposure affects development of cognitive skills is not known. Small changes have been found in older children. This study focused on children's exposures to MP and CP and cognitive development. The hypothesis was that children who used these phones would display differences in cognitive function compared to those who did not. Methods: We recruited 619 fourth-grade students (8-11 years) from 37 schools around Melbourne and Wollongong, Australia. Participants completed a short questionnaire, a computerised cognitive test battery, and the Stroop colour-word …

Cannabis use has been associated with impaired cognition during acute intoxication as well as in the unintoxicated state in long-term users. However, the evidence has been mixed and contested, and no systematic reviews of the literature on neuropsychological task-based measures of cognition have been conducted in an attempt to synthesize the findings. We systematically review the empirical research published in the past decade (from January 2004 to February 2015) on acute and chronic effects of cannabis and cannabinoids and on persistence or recovery after abstinence. We summarize the findings into the major categories of the cognitive domains investigated, considering sample …
Students' Reasoning Around The Functional Relationship, Michele Carney, Angela Crawford
Students' Reasoning Around The Functional Relationship, Michele Carney, Angela Crawford
Curriculum, Instruction, and Foundational Studies Faculty Publications and Presentations
Proportional reasoning is related to flexible use of the scalar and functional relationships that exist in proportional situations. More specifically, in regard to the functional relationship, students’ understanding of the multiplicative comparison that exists between two quantities in a ratio is a key concept. We conducted student interviews with 12 high performing students to examine their conception of the functional relationship. Analyses provided initial evidence that the majority of students did not conceive of the multiplicative comparison when solving problems designed to press the functional relationship, indicating students’ written work that makes use of the functional relationship should not imply …
