The digital literacy debate: an investigation of digital propensity and information and communication technology 总被引:1,自引:0,他引:1

Research suggests students’ use of information and communication technology (ICT) may be more a matter of digital literacy
and access rather than a generational trait. We sought to identify ICT preferences of post-secondary students (N = 580) through a Digital Propensity Index (DPI), investigating communication methods, Internet practices and the creation
of online content. Age, gender and socioeconomic status were examined as factors which might explain why students use ICT.
Results suggest age is a factor in ICT use but that it is not the most important consideration; the gender gap and gaps between
socioeconomic groups in terms of ICT use may be closing. The findings raise a variety of implications for institutions training
pre-service teachers, curriculum developers designing instructional materials and educational leaders developing ICT policy
for schools. 相似文献

The purpose of this paper is to describe the procedures and the analysis of an instrument designed to measure preservice teachers’
ability to develop appropriate 5E learning cycle lesson plans. The 5E inquiry lesson plan (ILP) rubric is comprised of 12 items with a scoring range of zero to four points per item. Content validity was determined
through the expertise of a panel of five science educators. Sixty six preservice teachers enrolled in elementary science methods
at three universities prepared lesson plans, which were scored by their instructors using the ILP rubric. Using a Pearson
two-tailed correlation, inter-rater reliability was established at a value of 0.83. An exploratory factor analysis provided
evidence of construct validity, with three factors. The factors included (1) explore, (2) engage/explain/elaborate, and (3)
evaluate. In addition, a secondary analysis revealed the means and standard deviations of the students' performance on each
of the phases of the 5E that include: engage, explore, explain, elaborate, and evaluate. The engage item held the highest
mean rating, and the evaluation items had the lowest mean ratings. Examination of the instrument's structure in light of the
5E phases is discussed and provides directions for future revisions and research. 相似文献

This paper contributes to arguments for the potential of Giddens’ structuration theory in educational research. It illustrates how ‘conceptual schemes’ from structuration theory were applied to the author’s empirical research on a type of alternative educational practice in India, ‘private school outreach’. It shows how Giddens’ concepts of ‘social system’, ‘structure’ and ‘agency’ helped to conceptualize private school outreach, and how ‘constraint’ and ‘ontological security’ offered explanations of apparent contradictions in private school outreach practice within the context of the reasons and motivations of actors. It also argues that when schools attempt to do things differently, contradictions may occur because the same ‘rules and resources’ that are drawn on in the production of alternative practice are drawn on in the reproduction of practice. Finally, acknowledging the debates around structuration theory, some of its key criticisms are addressed in relation to the empirical application. 相似文献

Research Findings: The current study examined achievement motivation orientation in preschool-age children from low- and middle-income families. Participants were 126 children who were attending an urban Head Start site or a private preschool. Children's motivation orientation was assessed as being performance oriented or mastery oriented using a challenging puzzle task (Smiley &; Dweck, 1994). Children's verbalizations during the task were coded into performance concern, disengaged, and negative self-evaluation categories. Logistic regression and Mann-Whitney U analyses were conducted to examine differences between income groups in motivation orientation and verbalizations. Patterns of motivation orientation in preschool-age children from low- and middle-income families did not differ after controlling for differences in age and puzzle-solving ability. However, children from low-income families made a significantly higher proportion of performance-related verbalizations while working on the task. Practice or Policy: The findings support the examination of children's private speech as a way to assess cognitive processes underlying achievement motivation. In addition to providing a novel way to identify differences in achievement motivation that may be useful for teachers and researchers, the findings suggest the potential utility of designing interventions that promote positive private speech as a way of supporting mastery-oriented motivation in young children. 相似文献

The existing literature suggests that crank inertial load has little effect on the responses of untrained cyclists. However, it would be useful to be aware of any possible effect in the trained population, particularly considering the many laboratory-based studies that are conducted using relatively low-inertia ergometers. Ten competitive cyclists (mean VO(2max) = 62.7 ml x kg(-1) x min(-1), s = 6.1) attended the human performance laboratories at the University of Wolverhampton. Each cyclist completed two 7-min trials, at two separate inertial loads, in a counterbalanced order. The inertial loads used were 94.2 kg x m(2) (high-inertia trial) and 2.4 kg x m(2) (low-inertia trial). Several physiological and biomechanical measures were undertaken. There were no differences between inertial loads for mean peak torque, mean minimum torque, oxygen uptake, blood lactate concentration or perceived exertion. Several measures showed intra-individual variability with blood lactate concentration and mean minimum torque, demonstrating coefficients of variation > 10%. However, the results presented here are mostly consistent with previous work in suggesting that crank inertial load has little direct effect on either physiology or propulsion biomechanics during steady-state cycling, at least when cadence is controlled. 相似文献

By 1837, the sporting landscape of England was populated by a number of professional pedestrians who competed in a range of events that were extensively covered in the sporting press. These men distinguished themselves from their competitors through their use of ‘colours’ and a range of different athletic clothing. In the later stages of the nineteenth century, the dominance of the professional athlete was challenged through the formation of clubs and associations by a public-school- and university-educated middle class. The somatotype and clothing strategies of the Victorian athlete altered as a result. Their assumption of an innate physical superiority, allied to a preference for the all-rounder with his elegance and style, rather than the muscular, specialized sporting bodies of working-class professionals, were important features of an amateur ethos which drew much of its references from the Classical world. Through a discussion of how middle-class amateur athletes used Classical precedents, science and clothing to create the ‘university athlete’ and the ‘university costume’, in order to reinforce the distinctions between their own bodies and those of the professionals, this paper explores the transition from pedestrianism to organized athletics. 相似文献
