This article examines the development and ultimate demise of the Ultranet, a major ICT infrastructure project in the education system of the Australian State of Victoria. The case is interesting as it was a very large project, intended for 1500 schools and funded to $180 m (Au). The study traces the design and implementation of the project as a socio-technical innovation in education. Although there are examples of how this project worked very well, its uptake was less than anticipated. The study found that potential benefits from a very large project like this can be nullified by a number of factors including: change in sponsorship of the project, an over emphasis on security concerns, failure to enrol crucial stakeholders and a naive assumption by technologists that technology with potential benefits will always be accepted. The study also found that technology projects must be delivered where a need exists and one that, most importantly, is recognised by the stakeholders. This will also be the case in other education systems around the world. If resources are not to be wasted the problem must be clearly identified and its need accepted before a solution is proposed. The Victorian Government finally abandoned the Ultranet in June 2013.  相似文献

Sharing folktales with young children offers an array of opportunities. These stories have universal appeal, abate fears, support divergent thinking, and connect generations. Eleven newest renditions of classic tales are reviewed and recommended.  相似文献

Parents are viewed as children’s first literacy teachers. As such, they are often encouraged to book share and read with their young children. Low literate parents may lack not only basic reading skills, but also second order skills related to sharing books successfully. Early childhood professionals are encouraged to form a dynamic, reciprocal relationship with parents wherein everyone learns and supports the literacy needs of children. Seventeen current children’s books are reviewed and recommended for sharing with children and families.  相似文献

This article explores how children can learn about environmental sciences through place-based education and children’s literature. Recent studies suggest that there is a lack of environmental science knowledge among citizens of all ages. Scholars and educators recommend introducing young children to the places in which they live to create an impact on how they will view and respect the natural world as adults. Selection and use of developmentally appropriate and scientifically accurate literature can be an effective tool to help children understand their place in and connections to the natural world. Guidelines for selecting place-based literature are presented using the Midwest United States as an example. Twelve children’s books are recommended and reviewed.  相似文献

We describe the development and administration of a recently introduced computer-based test of writing skills. This test asks the examinee to edit a writing passage presented on a computer screen. To do this, the examinee moves a cursor to a suspect section of the passage and chooses from a list of alternative ways o f rewriting that section. Any or all parts o f the passage can be changed, as often as the examinee likes. An able examinee identifies and fixes errors in grammar, organization, and style, whereas a less able examinee may leave errors untouched, replace an error with another error, or even introduce errors where none existed previously. All these response alternatives contrive to present both obvious and subtle scoring difficulties. These difficulties were attacked through the combined use of option weighting and the sequential probability ratio test, the result o f which is to classify examinees into several discrete ability groups. Item calibration was enabled by augmenting sparse pretest samples through data meiosis, in which response vectors were randomly recombined to produce offspring that retained much of the character of their parents. These procedures are described, and operational examples are offered.  相似文献

The aim of this study was to examine the effect of fatigue from maximal tennis hitting on skilled tennis performance. Eighteen senior county tennis players (9 males, 9 females) volunteered to participate in the study. Their mean ( - s x -macron ) age and body mass were as follows: males 20.7 - 0.9 years and 60.6 - 2.7 kg respectively, females 21.7 - 0.6 years and 71.5 - 1.8 kg respectively. The players undertook two performance tests, both against a tennis ball serving machine, on an indoor tennis surface: (1) a pre- and post-skill test of groundstrokes and service; (2) the Loughborough Intermittent Tennis Test (4 min work plus 40 s recovery) to volitional fatigue. Body mass decreased by 1.5% ( P ? 0.0001). Mean heart rates differed between rest, post-warm-up and all intermittent test values ( P ? 0.01), between the pre- and post-skill tests ( P ? 0.0001) and between bouts and recoveries ( P ? 0.01). Peak blood glucose and lactate concentrations were 5.9 mmol· l -1 (50% into the intermittent tennis test) and 9.6 - 0.9 mmol· l -1 (25% into the test) respectively. Mean time to volitional fatigue was 35.4 - 4.6 min. Groundstroke hitting accuracy decreased by 69% from start to volitional fatigue in the intermittent test ( P ? 0.01). Service accuracy to the right court declined by 30% after the intermittent tennis test. The results of this study suggest that fatigue was accompanied by a decline in some but not all tennis skills.  相似文献
