To address reduced physical education (PE) in elementary schools, a 12-week physical activity protocol was tested on 5-12-year-old, primarily African American, girls (n = 226) and boys (n = 344) at 14 YMCA after-school care sites. The 3 times/week, 45-min session curriculum included cardiovascular, resistance, and flexibility training, in which all children could participate simultaneously, and a behavioral skills education component. After-school counselors, formerly untrained in PE methods, administered the sessions, with periodic supervision by YMCA wellness staff members. Analyses of the eight Age x Sex subsamples indicated significant improvements on body composition, strength, and endurance, both within-groups and when predicted changes due to maturation were accounted for. Exercise barriers self-efficacy significantly increased in subsamples of 9-10- and 11-12-year-old girls only. The need for replication across ethnic groups was suggested. Limitations and the need for extension of research on supplementation of elementary school PE were discussed. 相似文献

Translating basic sciences into a clinical framework has been approached through the implementation of various teaching techniques aimed at using a patient case scenario to facilitate learning. These techniques present students with a specific patient case and lead the students to discuss physiological processes through analysis of provided data supported by independent learning and research. However, no literature exists that describes a reverse teaching methodology in which students are given disease diagnosis and then asked to construct a patient case. This article discusses an explorative learning approach introduced in the gross anatomy course in which students were asked to use clinical skills and reasoning to create a patient case. The online knowledge‐sharing portal utilizing MediaWiki provided a necessary base for students in completing their task. Teams were given 4 weeks to complete their written online project with weekly feedback provided by 3rd year teaching assistants using the Wiki discussion page. A survey was performed to assess competence regarding a patient write up and oral presentation. Skills that the teams acquired through the completion of this project will benefit future patient interactions. This project also emphasized and reinforced the importance of effective communication, leadership, and teamwork. This study shows that a clinical anatomy project that incorporates explorative learning can be an effective way of introducing students to the skills needed for patient write ups and oral presentations. Furthermore this approach to learning allows students to excel during their clinical years and to correlate anatomy to clinical diagnoses.

AbstractThe purpose of this research was to compare the beliefs and attitudes of teachers using the flipped versus the traditional class model. Survey and interview data were collected from a matched sample of in-service teachers representing both models from a large suburban southeastern Texas school district. The Attitude Towards Technology Scale, the Frequency of Involvement in Technology Scale, the Technology Comfort Scale, and the Technology and Teaching Efficacy Scale were administered to compare the beliefs and attitudes of teachers. Additionally, one-on-one interviews further explored the teacher beliefs and attitudes associated with the impact of technology on student engagement. Findings suggest that flipped classroom teachers have higher technology and teaching efficacy, greater comfort levels using technology, higher frequency of involvement in technology, more positive attitudes toward technology, and greater levels of student engagement. 相似文献

SummaryAt the archaeological site of Gordion, Turkey, all registered ceramics are routinely desalinated. The standard desalination treatment was investigated by the author with a view to minimizing damage to the ceramics, as well as the amount of water used and the time taken for desalination. An equation that standardizes conductivity measurements in disparate desalination situations is presented. A series of experiments was performed to clarify the behavior of salts at Gordion. Two variables which directly affect the amount of water needed for desalination were considered: the frequency of water changes and the weight-to-volume ratio. The experimental results were compared to on-site experience, and a revised endpoint for desalination is proposed. 相似文献

The profession of school psychology has been impacted by the response to intervention (RTI) model in various ways. RTI data are being used to make decisions regarding academic and behavioral interventions and to make eligibility determinations in comprehensive evaluations conducted by multidisciplinary teams. A survey of almost 400 school psychologist practitioners reveals a changing landscape in terms of school psychologists’ methods of determining eligibility for specific learning disabilities (SLD) in RTI site and non‐RTI site schools. The survey also brings to light differences between numbers of initial evaluations and levels of challenge and job satisfaction. Implications of these changes and future directions for research are discussed. 相似文献

The first enantioselective assembly of sandwich-shaped organo molecules has been achieved by conducting dual asymmetric Suzuki-Miyaura couplings and nine other reactions. This work also presents the first fully C-C anchored multi-layer 3D chirality with optically pure enantiomers. As confirmed by X-ray diffraction analysis that this chiral framework is featured by a unique C2-symmetry in which a nearly parallel fashion consisting of three layers: top, middle and bottom aromatic rings. Unlike the documented planar or axial chirality, the present chirality shows its top and bottom layers restrict each other from free rotation, i.e., this multi-layer 3D chirality would not exist if either top or bottom layer is removed. Nearly all multi-layered compounds showed strong luminescence of different colors under UV irradiation, and several randomly selected samples displayed aggregation-induced emission (AIE) properties. This work is believed to have broad impacts on chemical, medicinal and material sciences including optoelectronic materials in future. 相似文献

This study was designed to investigate the convergent validity of individual clinical task interviews as presented by Piaget and Inhelder paired with three widely used group tests of cognitive development. These tests are designed to assess the acquisition of cognitive abilities. The three group test raw scores paired with summed raw scores on four concrete-formal task interviews yielded the following Pearson product-moment correlations: Reasoning Test (Ankney and Joyce), 0.43; Logical Reasoning Test (Burney), 0.61; Classroom Test of Formal Operations (Lawson), 0.37. The raw data was then ranked into cognitive level groups and presented on contingency tables. The following contingency coefficients were determined: Logical Reasoning Test, 0.52; Logical Reasoning Test (adjusted), 0.61; Classroom Test of Formal Operations, 0.50. This study reflects that the Reasoning Test tends to indicate lower cognitive levels of subjects when paired with summed scores on the clinical task interviews, whereas the Logical Reasoning Test and the Classroom Test of Formal Operations tend to indicate higher cognitive levels of subjects when paired with summed scores on the clinical task interviews. In each case the correlations do not appear to be sufficiently strong to warrant selection or categorization of an individual student based on his/her test performance. 相似文献
