There is, no doubt, untapped potential in using technological tools to enhance the understanding of science concepts. This study examines the potential by observing 7th and 8th grade middle school students’ (n = 23) use of portable data collection devices in a nine-week elective class, Exploring Technologies. Students’ use of the data collection devices and subsequent interactions were traced through audiocassette and videocassette recordings, field notes, and student artifacts. The culminating activity for the course was a scientific investigation that required students to use the technologies to answer student-selected research questions. To illustrate the use of technology as a mediatory tool, an inquiry investigation of three student groups is described. In examining the three groups of middle school students the researchers encountered specific evidence of technology maximizing students’ science learning. The students were able to use the portable data collection devices in their investigations as they discussed scientific ideas related to temperature and heat. The study’s findings indicated that the three student groups were able to use the tools to conduct scientific inquiry and engage in scientific discourse. Further research on instructional approaches that allow students to develop expertise by using technology as tools to construct knowledge about complex phenomena is encouraged.  相似文献   

Towards an implementation framework for business intelligence in healthcare     

Neil Foshay  Craig Kuziemsky 《International Journal of Information Management》2014

As healthcare organizations continue to be asked to do more with less, access to information is essential for sound evidence-based decision making. Business intelligence (BI) systems are designed to deliver decision-support information and have been repeatedly shown to provide value to organizations. Many healthcare organizations have yet to implement BI systems and no existing research provides a healthcare-specific framework to guide implementation. To address this research gap, we employ a case study in a Canadian Health Authority in order to address three questions: (1) what are the most significant adverse impacts to the organization's decision processes and outcomes attributable to a lack of decision-support capabilities? (2) what are the root causes of these impacts, and what workarounds do they necessitate? and (3) in light of the issues identified, what are the key considerations for healthcare organizations in the early stages of BI implementation? Using the concept of co-agency as a guide we identified significant decision-related adverse impacts and their root causes. We found strong management support, the right skill sets and an information-oriented culture to be key implementation considerations. Our major contribution is a framework for defining and prioritizing decision-support information needs in the context of healthcare-specific processes.  相似文献

Effect of ischemic preconditioning on repeated sprint ability in team sport athletes     

Neil Gibson  Ben Mahony  Claire Tracey  Samantha Fawkner  Andrew Murray 《Journal of sports sciences》2015,33(11):1182-1188

This study investigated whether ischemic preconditioning (IPC) in a trained population affected repeated sprint performance. A secondary aim was to assess responses according to gender. Sixteen (nine females and seven males) well trained team sport athletes took part in a randomised crossover study design. Participants underwent an IPC and placebo treatment involving three periods of 5 min occlusion applied unilaterally (3 × 5 min occlusion to each leg) at either 220 mmHg or 50 mmHg. Each period of occlusion was followed by 5 min reperfusion. Following treatment 5 × 6 s maximal effort sprints were undertaken on a cycle ergometer against 7.5% body mass, each interspersed by 24 s recovery. Measured parameters included peak power, total power, percentage decrement, post-exercise blood lactate and ratings of perceived exertion. Nor within subject main effect for IPC was observed, neither was there an interaction effect with gender. Effect sizes were trivial (ES < 0.2) with the exception of a moderate (ES < 1.2) change in post-exercise blood lactate in the female cohort (1.6 ± 0.4 mmol^?1 lower following IPC). Results suggest no benefit to team sport players in utilising IPC as a means of enhancing repeated sprint performance. A lower blood lactate response in female participants following IPC may suggest improved blood flow through vasodilation.  相似文献

Navigating puberty,identity, and race among transnationally,transracially adopted Korean American adolescents     

Christine S. Wu  Adam Y. Kim  Eleanor K. Seaton  Rona Carter  Richard M. Lee 《Child development》2023,94(3):768-778

This exploratory study examined the relation between pubertal timing and dimensions of ethnic-racial identity among adopted Korean Americans raised transracially in White families. The study also examined whether internalized racism moderated the association between pubertal timing and ethnic-racial identity. Adopted Korean American adolescents (N = 202; 108 females; ages 13–19 years) completed measures of pubertal development, ethnic-racial identity, and internalized racism in 2007. There was no significant main effect of pubertal timing for either male or female adolescents. Internalized racism moderated the relation between pubertal timing and ethnic-racial identity clarity (B = −.16, p = .015) among male adolescents. Specifically, earlier pubertal timing was significantly associated with lower ethnic-racial identity clarity for male adolescents with higher levels of internalized racism.  相似文献

The Impact of Neighborhood,Family, and Individual Risk Factors on Toddlers’ Disruptive Behavior     

Amy E. Heberle  Yolanda M. Thomas  Robert L. Wagmiller  Margaret J. Briggs‐Gowan  Alice S. Carter 《Child development》2014,85(5):2046-2061

Disadvantaged neighborhoods confer risk for behavior problems in school‐aged children but their impact in toddlerhood is unknown. Relations between toddlers’ disruptive behavior and neighborhood disadvantage, family disadvantage, violence or conflict exposure, parent depressive symptoms, and parenting behavior were examined using multilevel, multigroup (girl–boy) models. Participants were 1,204 families (mean child age = 24.7 months). Unique associations between disruptive behavior and all risk factors were observed, but the effect of neighborhood disadvantage was negligible when all of the more proximal factors were accounted for. The results suggest both that children in disadvantaged neighborhoods are at greater risk of behavior problems than children in nondisadvantaged neighborhoods and that optimal prevention/intervention work with these children will attend to proximal risk factors.  相似文献   

Paying for quality? Associations between private school income,performance and use of resources          下载免费PDF全文

Peter Davies  Neil M. Davies 《British Educational Research Journal》2014,40(3):421-440

Education policy in England has explicitly aimed to remodel state schools in the image of independent, private, schools. However, the body of research evidence on the operation of private schools is very small. Critics have frequently argued that, in contrast to state schools, private schools use resources efficiently because their autonomy gives them freedom to make efficient choices in response to market pressures. We investigated the resource allocation decisions of income private schools using data from their financial accounts. We report the associations of private school spending and performance and teacher and non‐teacher numbers, teacher salaries and regional earnings. Schools with higher fees had more teachers and non‐teachers per pupil, but similar average staff wages to schools with lower income. Yet we found little evidence that achievement was associated with resource use in English private schools. That is, we found no evidence to support the view that financial autonomy enabled flexibility in using resources to promote higher achievement.  相似文献
