Joey and Mary, along with three other children and the teacher, are seated at one of several tables having their snack. Mary's plate has no crackers. Giggling, Mary begins poking at Joey's plate, which still has crackers, as if she intends to snatch one. The teacher asks, “Mary, would you like more crackers?” Mary continues the poking action during the interchange and responds, “Yes.” The teacher directs Mary, saying, “Get a package of crackers from the supply table and see if other tables need additional crackers. If you would like more, then get three crackers for yourself”.  相似文献

The results of a survey of secondary English Shakespeare teaching in one local education authority are reported. Centralised control of curriculum content in English is discussed in relation to findings about how much Shakespeare teaching is done and which plays teachers selected. The suggestion is made that recent controversy about content direction has deflected attention from the more important issues of methods of teaching and in‐service education.  相似文献

Abstract This paper investigates the meaningful choices in intonation made by young children. A category system for classifying choices is outlined and an experiment is reported in which randomly selected groups of 41/2‐5 year‐olds heard and retold stories in different situations. Results indicate that all groups distinguished narrative from other forms of discourse and drew upon intonation resources appropriately. Differences were found between recalling a story with pictures and one without, suggesting that these are different cognitive tasks and that children make different selections from choices available to them.  相似文献

Like all public libraries, rural public libraries in the Appalachian region can play a significant role in the economic development of their communities. Economic development in rural communities potentially benefit from many of the same resources and services all enjoy at public libraries, including free and public Internet access, space, education, question answering, and materials on many business-related subjects. This article reports survey findings of current activities that rural public libraries perform in one state, namely the state of Tennessee, as a case study to apply the lessons and insights to other parts of the United States. The discussion includes assessment of activities and some recommendations to streamline and stimulate all public libraries in conducting this assistance efficiently.  相似文献

Key points

  • New forms of human/machine dialogue are emerging as robots understand vast amounts of content rather than simply indexing content as strings of characters.
  • Recognizing strings of characters as entities (e.g. = names = authors) allows for meaningful associations between entities and reasoning over these relationships.
  • Web‐scale adoption of the Semantic Web approach has been slow because it is too complex to implement and does not scale.
  • User intent, discovered through conversational models of human–computer interaction, allows for a deeper understanding of exactly what researchers are looking for.
  • Personal agents hold the promise of finding information that we will find useful before we have started to look for it.
  • Publishers can use Academic Knowledge APIs to interpret academic user queries and find rich information from the Microsoft Academic Graph.

Graded exercise tests are commonly used to assess peak physiological capacities of athletes. However, unlike time trials, these tests do not provide performance information. The aim of this study was to examine the peak physiological responses of female outrigger canoeists to a 1000-m ergometer time trial and compare the time-trial performance to two graded exercise tests performed at increments of 7.5 W each minute and 15 W each two minutes respectively. 17 trained female outrigger canoeists completed the time trial on an outrigger canoe ergometer with heart rate (HR), stroke rate, power output, and oxygen consumption (VO2) determined every 15 s. The mean (+/- s) time-trial time was 359 +/- 33 s, with a mean power output of 65 +/- 16 W and mean stroke rate of 56 +/- 4 strokes min(-1). Mean values for peak VO2, peak heart rate, and mean heart rate were 3.17 +/- 0.67 litres min(-1), 177 +/- 11 beats min(-1), and 164 +/- 12 beats min(-1) respectively. Compared with the graded exercise tests, the time-trial elicited similar values for peak heart rate, peak power output, peak blood lactate concentration, and peak VO2. As a time trial is sport-specific and can simultaneously quantify sprint performance and peak physiological responses in outrigger canoeing, it is suggested that a time trial be used by coaches for crew selection as it doubles as a reliable performance measure and a protocol for monitoring peak aerobic capacity of female outrigger canoeists.  相似文献
