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

A learning strategies program emphasizing primary (text-oriented), and support (affective) strategies was evaluated. Participants were given training in one of two sequences: primary-support or support-primary. A no-treatment group served as a control. In general, the results revealed that strategy training significantly improved performance on both text-processing and self-report measures. The primary-support group typically scored higher than the support-primary group on the text-processing measures. Conversely, the support-primary group reported more positive responses on the self-report measures. Long-term follow-up results are also presented. 相似文献

This study evaluates the use of full-text databases amongst 425 undergraduate and graduate students in western New York. A review of literature implicated convenience, time issues, article retrieval option knowledge, and the appreciation and understanding of research article quality as potential predictors of full-text reliance. These variables were then evaluated via survey response and frequency counts, by conducting correlations, a one-way ANOVA, and stepwise regression analyses. The findings suggested that convenience, appreciation and understanding of research quality, and time management issues played a significant role in the prediction of student full-text reliance. These findings as well as the relationships among independent variables are discussed. Implications for instruction are then addressed. 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

The widespread use of handheld computers and other mobile devices in the healthcare environment and their potential for providing access to information has prompted health sciences librarians everywhere to learn more about this technology. Early in 2001, the Health Sciences Library (HSL) at the University of North Carolina at Chapel Hill began exploring ways to support mobile computing. This paper describes the four basic approaches taken by the librarians that helped establish the HSL as a leader in the area of mobile technologies. 相似文献
