Compared to competitive runners, recreational runners appear to be more prone to injuries, which have been associated with foot strike patterns. Surprisingly, only few studies had examined the foot strike patterns outside laboratories. Therefore, this study compared the foot strike patterns in recreational runners at outdoor tracks with previously reported data. We also investigated the relationship between foot strike pattern, speed, and footwear in this cohort. Among 434 recreational runners analysed, 89.6% of them landed with rearfoot strike (RFS). Only 6.9 and 3.5% landed with midfoot and forefoot, respectively. A significant shift towards non-RFS was observed in our cohort, when compared with previously reported data. When speed increased by 1 m/s, the odds of having forefoot strike and midfoot strike relative to RFS increased by 2.3 times and 2.6 times, respectively. Runners were 9.2 times more likely to run with a forefoot strike in minimalists compared to regular running shoes, although 70% of runners in minimalists continued to use a RFS. These findings suggest that foot strike pattern may differ across running conditions and runners should consider these factors in order to mitigate potential injury. 相似文献

The present study examined the role of verbal working memory (memory span and tongue-twister), two-character Chinese pseudoword reading (two tasks), rapid automatized naming (RAN) (letters and numbers), and phonological segmentation (deletion of rimes and onsets) in inferential text comprehension in Chinese in 31 less competent comprehenders compared with 37 reading comprehension control students and 23 chronological age controls. It was hypothesized that the target students would perform poorly on these cognitive and linguistic tasks as compared with their controls. Furthermore, verbal working memory and pseudoword reading would explain a considerable amount of individual variation in Chinese text comprehension. RAN would have a nonsignificant role in text comprehension. Structural equation analyses and hierarchical multiple regression analyses generally upheld these hypotheses. Our findings support current literature of the role of verbal working memory in reading comprehension found in English. The results, however, suggest differential role of the constructs and the tasks in reading comprehension and provide some answers for comprehension impairment in Chinese students. 相似文献

Under the new four-year undergraduate programme, a general education framework titled ‘General University Requirements’ (GUR) has been developed and implemented since 2012/2013 at Hong Kong Polytechnic University (PolyU). To evaluate the implementation and effectiveness of the GUR in its first year, focus group interviews with students were carried out. In 13 focus groups, 62 first-year students from eight faculties/schools who took GUR subjects in 2012/2013 academic year were interviewed by trained researchers. Results showed that students generally had good perceptions of the GUR in terms of the subject content, teaching methods and the overall effectiveness of the subjects. The interactive teaching and learning initiatives adopted in GUR subjects were particularly appreciated, although students expressed minor concerns on the administration of GUR subjects. The results suggest that the first-year implementation of the GUR at PolyU was generally smooth and successful from the perspectives of the students. 相似文献

This study investigated how peer comments made using a video annotation tool (VAT) through an online learning community improved student-teachers’ level of reflective thinking and communication competence throughout the simulated (i.e., role-play) context of consultation practice. Eighty student-teachers from two classes of the course “Comprehensive School Guidance” participated in this study, and all recorded two videos for their tripartite practice on parent consultation for self-evaluation and peer comment. Forty student-teachers were in the comparison class and provided general comments to their peers on the learning platform, while those in the experimental class used the VAT on the learning platform to provide specific comments to their peers. Two post-practice online questionnaires and reflective journal entries, which aimed to measure communication competence and reflective thinking ability, were administered to the student-teachers after the first and second consultation practice. The reflective journal entries were segmented into units of analysis that were scored using a 4-level model of reflective thinking (from 1 to 4), with a higher score indicating demonstration of a higher level of reflective thinking for that particular segment. Both the number of reflective notes made and the average level of reflective thinking in student-teachers’ journal entries were indicators of reflective thinking ability. Two mixed ANOVAs were conducted to examine whether student-teachers in the experimental (VAT) class improved their reflective thinking ability and communication competence more significantly than those in the comparison (non-VAT) class. The results showed that student-teachers in both the VAT and non-VAT classes had statistically higher scores for communication competence and reflective thinking in the second role-play practice. Student-teachers with the support of VAT, in comparison to those without, significantly improved their average reflective thinking ability. Focus group interviews were also conducted to investigate how VAT could support student-teachers’ learning process and to learn their perceptions of the strengths and limitations of the VAT. The results indicated that the VAT could enhance student-teachers’ learning by reducing communication barriers created by the tendency to avoid direct observations of peers’ weaknesses, enhancing reflection-in-action during practice, and contextualizing written comments by referring to specific video segments. However, student-teachers felt that the VAT should also allow users to draw on the video screens.

This longitudinal study examined the relationship between pedagogical continuity in literacy education and early literacy development by comparing Chinese children in Hong Kong and Shenzhen. Stratified random sampling was used to select 24 preschool and Primary 1 classes in four communities catering to middle‐class families in each city. The 24 teachers were interviewed about their teaching methods and views on pedagogical continuity in individual sessions. Further, their teaching activities were videotaped over a period of a week. Their students (n = 758) completed a Chinese literacy attainment test at the beginning and at the end of the same academic year. Analyses indicated that Hong Kong students outperformed their Shenzhen counterparts in Chinese literacy attainment, at both preschool and primary levels, concurrently and longitudinally. This suggests that the holistic approach followed in Hong Kong might have a more positive impact on children's literacy development than the approach followed in Shenzhen. Implications of the findings for early childhood curriculum reform are discussed. 相似文献

The reading attainment of the 3,875 primary 4 Hong Kong primary school students participating in the 2011 Progress in International Reading Literacy Study ranked first among 49 countries and regions surveyed worldwide. Analysis of the association between (a) participating students’ reading attainment and (b) responses to questionnaires completed by the students and their parents revealed that classroom teaching, the school curriculum, the reader’s social and economic background and support from home had all helped shape reading performance. It is not unusual for school students in many Asian countries to receive after-school tuition in various areas of the curriculum to boost performance in impending examinations. The study reported here focussed (1) on the Chinese language reading attainment of students who had attended private tutoring classes after school in this subject against the scores of fellow students who had not and (2) asking whether such after-school tutoring had been of any notable benefit to their reading. Although a majority of the parents questioned said they paid for extra tuition for their children after school, analyses of the data found there was a statistically significant difference between the scores of students who received extra tuition and those who did not, the score of the latter group being superior. It is suggested that the Hong Kong education authorities reassure parents about the quality of teaching in primary schools and publicly pronounce on the potential value of after-school private tutoring. 相似文献

This study investigated whether child exuberance, an aspect of temperament related to emotion regulation, moderates the well-documented association between high parenting stress and increased risk for internalizing and externalizing problems during the preschool years. At 42 months of age child exuberance was observed in 256 children (47% girls) and maternal self-reports on parenting stress were obtained. At 48 months internalizing and externalizing problems were assessed through reports from both parents. Indeed, higher maternal parenting stress increased the risk for internalizing problems, and this association was more pronounced among children with high levels of exuberance. Existent emotion regulation difficulties in highly exuberant children may further heighten the risk conveyed by an unfavorable caregiving environment for developing internalizing problems. 相似文献

We investigated the effects of enhancing orthographic knowledge on the spelling of Chinese characters and words in 131 eight-year-old
Chinese children at risk for dyslexia. The traditional approach (37 children) emphasizing memory and repeated writing was
the control condition. The analytic and synthetic approach (ASA, 33 children) stressed insight into character structure. The
integrated analytic and synthetic approach added to ASA self-correction and metacognitive activities (INA, 61 children). The
children were first asked to write down as many words as possible associated with pictures of home, school, and community;
the correctly written words formed the baseline information. The children were then instructed by their classroom teachers
in six especially designed short texts and assessed in eight measurable bujian or radical tasks subserving three constructs: morpheme completion, bujian analysis and synthesis and bujian compounding.
Multivariate analyses of variance showed that the children in the INA condition outperformed those in the other conditions
in three of the measurable bujian tasks. A confirmatory factor analysis verified the stability of the eight tasks and their
clustering into three constructs. From these results, we tentatively propose a “bujian sensitivity hypothesis” as a means
of helping young Chinese children at risk for spelling disorders. 相似文献

The development of widely applicable point-of-care sensing and diagnostic devices can benefit from simple and inexpensive fabrication techniques that expedite the design, testing, and implementation of lab-on-a-chip devices. In particular, electrodes integrated within microfluidic devices enable the use of electrochemical techniques for the label-free detection of relevant analytes. This work presents a novel, simple, and cost-effective bench-top approach for the integration of high surface area three-dimensional structured electrodes fabricated on polystyrene (PS) within poly(dimethylsiloxane) (PDMS)-based microfluidics. Optimization of PS-PDMS bonding results in integrated devices that perform well under pressure and fluidic flow stress. Furthermore, the fabrication and bonding processes are shown to have no effect on sensing electrode performance. Finally, the on-chip sensing capabilities of a three-electrode electrochemical cell are demonstrated with a model redox compound, where the high surface area structured electrodes exhibit ultra-high sensitivity. We propose that the developed approach can significantly expedite and reduce the cost of fabrication of sensing devices where arrays of functionalized electrodes can be used for point-of-care analysis and diagnostics. 相似文献

Reading literacy of fourth‐grade students in Hong Kong showed a remarkable improvement from 2001 to 2006 as shown by international PIRLS studies. This study identified various aspects of the teacher factor contributing to the significant improvement among students. A total of 4,712 students and 144 teachers from 144 schools were randomly selected using probability proportional‐to‐size technique to receive the Reading Assessment Test and complete the Teacher's Questionnaire, respectively. A number of items pertaining to teachers' instructional strategies and activities, opportunities for students to read various types of materials, practices on assessment, and professional preparation and perception, were found to be significantly correlated with the outcome of students' reading literacy. Stepwise regression procedure revealed four significant predictors for students' overall reading achievement. The most powerful predictor was the use of materials from other subjects as reading resources. Suggestions to improve quality of teaching of reading and further studies are made. 相似文献
