A number of writers have drawn attention to the increasing importance of language in social life in ‘new times’ and Fairclough has referred to ‘discourse driven’ social change. These conditions have led to an increase in the use of various forms of discourse analysis in policy analysis. This paper explores the possibilities of using Critical Discourse Analysis (CDA) in critical policy research in education, drawing on a larger research project which is investigating the equity implications of Education Queensland’s reform agenda. It is argued that, in the context of new times, CDA is of particular value in documenting multiple and competing discourses in policy texts, in highlighting marginalized and hybrid discourses, and in documenting discursive shifts in policy implementation processes. The last part of the paper discusses how such research might be used by policy activists inside and outside education department bureaucracies to further social democratic goals.  相似文献

Children living in poverty are 1.3 times as likely as non‐poor children to experience reading difficulties and lack key oral experiences that contribute to early literacy development. The purpose of this research was to study the effects of viewing commercially available educational television with closed captions. Seventy second‐ and third‐grade economically disadvantaged children living in urban locations participated in this experimental research design. Children were randomly assigned to view videos with or without closed captions. Captions helped children recognise and read more words, identify the meaning of those words, generate inferences regarding programme content and transfer these skills to a normative code‐related skill task. Risk status moderated word recognition performance: those at risk benefited from captions while those who were not at risk recognised more words when captions were absent.  相似文献

We assessed the effects on basketball free throw performance of two types of verbal directions with an external attentional focus. Novices (n = 16) were pre-tested on free throw performance and assigned to two groups of similar ability (n = 8 in each). Both groups received verbal instructions with an external focus on either movement dynamics (movement form) or movement effects (e.g. ball trajectory relative to basket). The participants also observed a skilled model performing the task on either a small or large screen monitor, to ascertain the effects of visual presentation mode on task performance. After observation of six videotaped trials, all participants were given a post-test. Visual search patterns were monitored during observation and cross-referenced with performance on the pre- and post-test. Group effects were noted for verbal instructions and image size on visual search strategies and free throw performance. The 'movement effects' group saw a significant improvement in outcome scores between the pre-test and post-test. These results supported evidence that this group spent more viewing time on information outside the body than the 'movement dynamics' group. Image size affected both groups equally with more fixations of shorter duration when viewing the small screen. The results support the benefits of instructions when observing a model with an external focus on movement effects, not dynamics.  相似文献

Different methods of ball carrying can be used when a player runs with the ball in rugby union. We examined how three methods of ball carrying influenced sprinting speed: using both hands, under the left arm and under the right arm. These methods were compared with running without the ball. Our aim was to determine which method of ball carrying optimizes sprinting speed. Altogether, 48 rugby union players (age 21 +/- 2 years, height 1.83 +/- 0.1 m, body mass 85.3 +/- 12 kg, body fat 14 +/- 5%; mean +/- s) were recruited. The players performed twelve 30-m sprints in total (each player performed three trials under each of three methods of carrying the ball and sprinting without the ball). The design of the study was a form of Latin rectangle, balanced across the trial order for each of the methods and for pairwise combinations of the methods in blocks of four per trial. Each sprint consisted of a 10-m rolling start, followed by a 20-m timed section using electronic timing gates. Compared with sprinting 20 m without the ball (2.58 +/- 0.16 s), using both hands (2.62 +/- 0.16 s) led to a significantly slower time (P < 0.05). Sprinting 20 m with the ball under the left arm (2.61 +/- 0.15 s) or under the right arm (2.60 +/- 0.17 s) was significantly quicker than when using 'both hands' (P < 0.05), and both these methods were significantly slower than when running without the ball (P < 0.05). Accordingly, running with the ball in both hands led to the greatest decrement in sprinting performance, although carrying the ball under one arm also reduced the players' sprinting ability. Our results indicate that to gain a speed advantage players should carry the ball under one arm.  相似文献
