This article is a report of a meta-analysis on the question: “What are the effects of different instructional systems used in science teaching?” The studies utilized in this meta-analysis were identified by a process that included a systematic screening of all dissertations completed in the field of science education since 1950, an ERIC search of the literature, a systematic screening of selected research journals, and the standard procedure of identifying potentially relevant studies through examination of the bibliographies of the studies reviewed. In all, the 130 studies coded gave rise to 341 effect sizes. The mean effect size produced over all systems was 0.10 with a standard deviation of 0.41, indicating that, on the average, an innovative teaching system in this sample produced one-tenth of a standard deviation better performance than traditional science teaching. Particular kinds of teaching systems, however, produced results that varied from this overall result. Mean effect sizes were also computed by year of publication, form of publication, grade level, and subject matter.  相似文献

The nature of physical activity that benefits bone is traditionally thought to differ from that benefiting cardiovascular health. Accordingly, exercise recommendations for improving bone health and cardiovascular health are largely incongruent. Our aim was to determine the associations between high-impact physical activity participation and both cardiovascular disease risk factors and bone mass. We recruited 94 men and women (age 34.0?±?13.3 years) to undergo measures of cardiovascular disease risk (BMI, total cholesterol, fasting blood glucose, waist-to-hip ratio, and mean arterial pressure) and dual-energy X-ray absorptiometry (DXA XR-800, Norland) measures of bone mass (femoral neck, lumbar spine, and whole body BMD) and body composition (whole body lean mass and fat mass). Physical activity participation was estimated using the bone-specific physical activity questionnaire (BPAQ). Those in the upper tertile for current BPAQ score exhibited lower total cholesterol, waist-to-hip ratio, and mean arterial pressure than those in the lower tertiles (P?r?=??0.49 to 0.29, P?P?=?0.008), with BPAQ score predicting 6% of the variance in BMD (P?=?0.02). We conclude that high-impact physical activity as captured by the BPAQ may be beneficial for both bone health and for attenuating cardiovascular disease risk.  相似文献

This study investigated the relationship of locus-of-control orientations and task structure to the science problem-solving performance of 100 same-sex, sixth-grade student pairs. Pairs performed a four-variable problem-solving task, racing cylinders down a ramp in a series of trials to determine the 3 fastest of 18 different cylinders. The task was completed in one of two treatment conditions: the structured condition with moderate cuing and the unstructured condition with minimal cuing. Pairs completed an after-task assessment, predicting the results of proposed cylinder races, to measure the ability to understand and apply task concepts. Overall conclusions were: (1) There was no relationship between locus-of-control orientation and effectiveness of problem-solving strategy; (2) internality was significantly related to higher accuracy on task solutions and on after-task predictions; (3) there was no significant relationship between task structure and effectiveness of problem-solving strategy; (4) solutions to the task were more accurate in the unstructured task condition; (5) internality related to more accurate solutions in the unstructured task condition.  相似文献

Recent educational policy and practice have established an extended role for all subjects in addressing children and young peoples' academic and interpersonal development, with strategies facilitating key skills and wider learning across areas of Citizenship and Personal, Social and Health education providing an integrated approach to education and welfare. The significance of global development education within a holistic curriculum acknowledges the increased awareness of the interconnected nature of our relationship with each other and with the planet we share as world citizens. The arts have a strong track‐record in addressing such key issues – challenging hierarchical paradigms which reinforce prejudice and stereotyping, the arts encourage reflexive processes and critical engagement with diversity and pluralist perspectives. This article investigates curricular approaches to the global dimension within education in relation to theoretical perspectives and policies, presenting an intercultural art case study as a model of practice in engaging diverse participants in reflection on their own and others' experiences across a range of socio‐cultural contexts. Current political shifts reaffirming the centrality of the discrete disciplines over cross‐curricular practice could potentially undermine a more holistic approach to education. The article argues that policy and practice, implemented in response to changing political and philosophical ideology, must nevertheless maintain a commitment to fostering interdisciplinary values of cultural awareness. Such practice must form part of an inclusive internationalist educational vision, impacting on social cohesion.  相似文献
