This 2‐year longitudinal study examined both concurrent and longitudinal relations of a variety of reading‐related cognitive tasks and Chinese word reading and word dictation among 187 Hong Kong Chinese kindergarteners aged 4–6. Homophone awareness, visual skills and syllable awareness were all uniquely associated with Chinese word reading across time, with age, vocabulary knowledge and nonverbal IQ statistically controlled. Only visual skill and syllable deletion uniquely explained early Chinese word dictation, however. Results extend previous research on cognitive correlates of Chinese literacy and highlight the small but unique contribution of homophone awareness for early reading acquisition in Chinese.  相似文献

This study investigated the relationship between school sex education and sexual health behaviours at first sex and later in adulthood, using nationally representative data. Respondents were adults from the 2010 Irish Contraception and Crisis Pregnancy Survey, a cross-sectional survey designed to assess knowledge, attitudes and behaviours relating to sex, contraception and pregnancy in Ireland. Results indicate that respondents who received sex education were more likely to have first sex at an older age and use contraception on this occasion. Sex education also significantly increased the likelihood of using contraception at first sex, when first sex occurred before 17 years of age. The effect of sex education and sexual health behaviours into adulthood was also investigated. Sex education increased the likelihood of having a history of sexually transmitted infection testing and decreased the likelihood of having experienced a crisis pregnancy. No association was found between sex education and contraception use over the past year. Findings suggest that sex education is an important factor in the context of first sex and later sexual health, and programmes should continue to equip young people as they make immediate sexual behaviour decisions and further sexual health-related decisions throughout their lifespan.  相似文献

The purpose of this investigation was to compare valgus/varus knee angles during various jumps and lower body strength between males and females relative to body mass. Seventeen recreationally active females (age: 21.94 ± 2.59 years; height: 1.67 ± 0.05 m; mass: 64.42 ± 8.39 kg; percent body fat: 26.89 ± 6.26%; squat one-repetition maximum: 66.18 ± 19.47 kg; squat to body mass ratio: 1.03 ± 0.28) and 13 recreationally active males (age: 21.69 ± 1.65 years; height: 1.77 ± 0.07 m; mass: 72.39 ± 9.23 kg; percent body fat: 13.15 ± 5.18%; squat one-repetition maximum: 115.77 ± 30.40 kg; squat to body mass ratio: 1.59 ± 0.31) performed a one-repetition maximum in the squat and three of each of the following jumps: countermovement jump, 30 cm drop jump, 45 cm drop jump, and 60 cm drop jump. Knee angles were analysed using videography and body composition was analysed by dual-energy X-ray absorptiometry to allow for squat to body mass ratio and squat to fat free mass ratio to be calculated. Significant differences (P ≤ 0.05) were found between male and female one-repetition maximum, male and female squat to body mass ratio, and male and female squat to fat free mass ratio. Significant differences were found between male and female varus/valgus knee positions during maximum flexion of the right and left leg in the countermovement jump, drop jump from 30 cm, drop jump from 45 cm, and drop jump from 60 cm. Correlations between varus/valgus knee angles and squat to body mass ratio for all jumps displayed moderate, non-significant relationships (countermovement jump: r = 0.445; drop jump from 30 cm: r = 0.448; drop jump from 45 cm: r = 0.449; drop jump from 60 cm: r = 0.439). In conclusion, males and females have significantly different lower body strength and varus/valgus knee position when landing from jumps.  相似文献

A key consideration when giving any computerized adaptive test (CAT) is how much adaptation is present when the test is used in practice. This study introduces a new framework to measure the amount of adaptation of Rasch‐based CATs based on looking at the differences between the selected item locations (Rasch item difficulty parameters) of the administered items and target item locations determined from provisional ability estimates at the start of each item. Several new indices based on this framework are introduced and compared to previously suggested measures of adaptation using simulated and real test data. Results from the simulation indicate that some previously suggested indices are not as sensitive to changes in item pool size and the use of constraints as the new indices and may not work as well under different item selection rules. The simulation study and real data example also illustrate the utility of using the new indices to measure adaptation at both a group and individual level. Discussion is provided on how one may use several of the indices to measure adaptation of Rasch‐based CATs in practice.  相似文献

It is becoming increasingly clear that the concepts of open government data (OGD) and co-creation are related; however, there is currently only limited empirical material available exploring the link between the two. This paper aims to help clarify the relationship between these two concepts by exploring a recently coined phenomenon: OGD-driven co-created public services. These services 1) utilize or are driven by OGD; 2) are co-created by stakeholders from different groups; and 3) produce public value for society. Due to the relative newness of the phenomenon an inductive exploratory case study is undertaken on Chicago's use of OGD in the co-creation of their food safety inspection forecasting model. This model forecasts critical food safety violations at food serving establishments and sends inspectors to the highest risk establishments first. The results of this exploratory work led to the discovery of a ‘perfect storm’ of six factors that seem to play a key role in allowing OGD-driven public service co-creation to take place. These factors are motivated stakeholders, innovative leaders, proper communication, an existing OGD portal, external funding, and agile development.  相似文献

Medical students at the Cleveland Clinic Lerner College of Medicine of Case Western Reserve University receive instruction from a resident at the cadaver during their anatomy course. As discussed by McBride and Drake in this issue of ASE, residents teaching in the anatomy course at his institution who satisfy specific requirements qualify for an academic appointment as a Clinical Instructor.  相似文献

Although empirical research in academic areas provides support for both a 3-factor as well as a 4-factor achievement goal model, both models were proposed and tested with a collegiate sample. Little is known about the generalizability of either model with high school level samples. This study was designed to examine whether the 3-factor model (Mastery Goals, Performance-Approach Goals, and Performance-Avoidance Goals) or the 4-factor model (Mastery-Approach Goals, Mastery-Avoidance Goals, Performance-Approach Goals, and Performance-Avoidance Goals) is appropriate in high school physical education settings. The factorial validity of the models and internal consistency reliability were tested with confirmatory factor analysis, invariance testing, and tests of internal consistency across 2 samples. The results reveal that the items from the 4-factor achievement goal model can produce internally consistent and valid scores for high school students in physical education settings; the 4-factor model provides a better fit to the data than the 3-factor model. The multistep invariance analysis, however, reveals only metric invariance across 2 school samples.  相似文献

This study examined and compared the critical thinking dispositions (CT) of 218 American and 234 Chinese preservice physical education teachers. All were juniors or seniors and enrolled in physical education secondary teaching methods classes at the time of the study. Results provided evidence of a positive endorsement toward CT by the American sample, and a slight resistance by the Chinese participants on two of the four subscales from the California Critical Thinking Dispositions Inventory (CCTDI). The American sample scored significantly higher on two of the four subscales. Some of the differences between the two populations may stem from the duality of individualism-collectivism represented in Western and Asian cultures, respectively. Similarities noted between the two populations in CT dispositions, however, appear to transcend cultural differences and may serve as the basis for future research.  相似文献
