The present study sought to identify cognitive abilities that might distinguish Hong Kong Chinese adolescents with dyslexia and to assess how these abilities were associated with Chinese word reading, word dictation, and reading comprehension. The cognitive skills of interest were morphological awareness, visual-orthographic knowledge, rapid naming, and verbal working memory. A total of 90 junior secondary school students, 30 dyslexic, 30 chronological age controls, and 30 reading level controls was tested on a range of cognitive and literacy tasks. Dyslexic students were less competent than the control students in all cognitive and literacy measures. The regression analyses also showed that verbal working memory, rapid naming, morphological awareness, and visual-orthographic knowledge were significantly associated with literacy performance. Findings underscore the importance of these cognitive skills for Chinese literacy acquisition. Overall, this study highlights the persistent difficulties of Chinese dyslexic adolescents who seem to have multiple causes for reading and spelling difficulties. 相似文献

Student contribution in asynchronous online discussion: a review of the research and empirical exploration 总被引:1,自引:0,他引:1
The increasingly prevalent use of Internet in schools and homes has resulted in asynchronous online discussion becoming an
increasingly common means to facilitate dialogue between instructors and students, as well as students and students beyond
the boundaries of their physical classrooms. This article is organized into two main sections. In the first section, we review
50 empirical studies in order to identify the factors leading to limited student contribution. Limited student contribution
is defined as students making few or no postings, or students exhibiting surface-level thinking or low-level knowledge construction
in online discussions. We then identify the various empirically based guidelines to address the factors. In the second section,
we discuss three potential guideline dilemmas that educators may encounter: (a) use of grades, (b) use of number of posting
guideline, and (c) instructor-facilitation. These are guidelines where previous empirical research shows mixed results when
they are implemented. Acknowledging the dilemmas is essential for educators and researchers to make informed decisions about
the discussion guidelines they are considering implementing. Finally, we report two exploratory case studies on student-facilitation
that we conducted. Using students as facilitators may be an alternative solution to educators who wish to avoid the instructor-facilitation
guideline dilemma. 相似文献

Software for calculating blood lactate endurance markers 总被引:2,自引:2,他引:0

Blood lactate markers are used as summary measures of the underlying model of an athlete's blood lactate response to increasing work rate. Exercise physiologists use these endurance markers, typically corresponding to a work rate in the region of high curvature in the lactate curve, to predict and compare endurance ability. A short theoretical background of the commonly used markers is given and algorithms provided for their calculation. To date, no free software exists that allows the sports scientist to calculate these markers. In this paper, software is introduced for precisely this purpose that will calculate a variety of lactate markers for an individual athlete, an athlete at different instants (e.g. across a season), and simultaneously for a squad. 相似文献

The persistence and generality of the contextual interference (CI) effect was tested using a rapid sequential aiming task. Participants (N=48) practiced three movement patterns for three blocks of 18 trials under a blocked (BL) or random (RA) schedule. Movement patterns were displayed and KR provided throughout practice and testing. A 24-hr delayed knowledge of results (KR) retention test included three blocks of 18 trials, followed by a transfer test of a single new movement pattern. In contradiction of the CI effect, RA practice provided an advantage for RA retention only, not BL retention. Furthermore, group differences at transfer were not persistent. Hence, RA practice does not necessarily provide enhanced, context-free learning, but it is essential training for task switching. Overall the findings reveal limited persistence and generality of the CI effect. 相似文献

To provide a method for graduate engineers to acquire advanced degrees, some industrial organizations have instituted a part-time employee program. The difficulties encountered by an industry, an employee and an educational institution which have been involved in such a program are indicated in this paper. Suggestions are made, which should improve the benefits derived from such a program. Since programs of this type will provide a better qualified technical force for industry and the nation, they deserve the attention of educators at this time. Greater cooperation between industry and educational institutions will provide a benefit to all. 相似文献

This article argues that an enlightened, inclusive vision of universal service is possible by learning lessons from disability. Telecommunications policy has historically built in norms that needlessly exclude people who are regarded as having a disability and therefore being outside of the mainstream. Accordingly, universal service policies focus on availability and affordability of telecommunications services, rather than on their accessibility and functionality. The article shows how rethinking universal service through disability can lead to inclusive policies that benefit everybody. 相似文献
