Vocabulary knowledge has been shown to be a predictor of academic success, posing a challenge for children and young people with language disorder. Language disorder can persist into adolescence and yet there is limited evidence on how to support the vocabulary skills of adolescents with language disorder in a mainstream setting. This article describes an experimental study aimed at investigating the feasibility of a whole‐class approach to increase the understanding and use of curriculum vocabulary in adolescents with language disorder. Ten curriculum words were taught by the science teacher using a phonological‐semantic approach, and 10 matched same‐topic words were taught using routine teaching practice. Progress was made post‐intervention in word knowledge of both low‐frequency experimental and control words, with significantly greater change in knowledge of the experimental words. Most students, and the teacher, viewed the phonological‐semantic word‐learning approach favourably. 相似文献

Learning transfer from training and development programs to the workplace is a central issue of concern for human resource development specialists. Action Reflection Learning™ (ARL™) is a form of action learning that places emphasis on the development of targeted competencies while teams of participants work on real problems which have been given to them by a sponsor. This article examines the kinds of learning and learning transfer that took place in an international food company that was striving to become a global organization. Data were collected through both field observation and formal interviews and analyzed by a team of researchers. Conclusions about the degree of transfer and the mechanisms and process supporting it are presented. 相似文献

The aims of this study were two-fold: (1) to consider the criterion-related validity of the multi-stage fitness test (MSFT) by comparing the predicted maximal oxygen uptake (.VO(2max)) and distance travelled with peak oxygen uptake (VO(2peak)) measured using a wheelchair ergometer (n = 24); and (2) to assess the reliability of the MSFT in a sub-sample of wheelchair athletes (n = 10) measured on two occasions. Twenty-four trained male wheelchair basketball players (mean age 29 years, s = 6) took part in the study. All participants performed a continuous incremental wheelchair ergometer test to volitional exhaustion to determine .VO(2peak), and the MSFT on an indoor wooden basketball court. Mean ergometer .VO(2peak) was 2.66 litres . min(-1) (s = 0.49) and peak heart rate was 188 beats . min(-1) (s = 10). The group mean MSFT distance travelled was 2056 m (s = 272) and mean peak heart rate was 186 beats . min(-1) (s = 11). Low to moderate correlations (rho = 0.39 to 0.58; 95% confidence interval [CI]: -0.02 to 0.69 and 0.23 to 0.80) were found between distance travelled in the MSFT and different expressions of wheelchair ergometer .VO(2peak). There was a mean bias of -1.9 beats . min(-1) (95% CI: -5.9 to 2.0) and standard error of measurement of 6.6 beats . min(-1) (95% CI: 5.4 to 8.8) between the ergometer and MSFT peak heart rates. A similar comparison of ergometer and predicted MSFT .VO(2peak) values revealed a large mean systematic bias of 15.3 ml . kg(-1) . min(-1) (95% CI: 13.2 to 17.4) and standard error of measurement of 3.5 ml . kg(-1) . min(-1) (95% CI: 2.8 to 4.6). Small standard errors of measurement for MSFT distance travelled (86 m; 95% CI: 59 to 157) and MSFT peak heart rate (2.4 beats . min(-1); 95% CI: 1.7 to 4.5) suggest that these variables can be measured reliably. The results suggest that the multi-stage fitness test provides reliable data with this population, but does not fully reflect the aerobic capacity of wheelchair athletes directly. 相似文献

The crystallization of soluble salts plays a significant role in the deterioration of porous cultural property. A common response to salt damage problems is to undertake treatments aimed at reducing the salt content of the affected object, most typically through the application of poultices. The process of poulticing is in theory relatively simple: the wet poultice material is applied to the surface of the object to be treated, and is kept in place for some period of time before being removed. However, in practice, the efficiency of the salt extraction, or even the location of salt accumulation post treatment is more difficult to predict. This paper examines the physical principles of salt ion and moisture transport by which poultices function, and shows how depending on the application methodology, these treatments can be divided into diffusion and advection-based methods. The maximum salt extraction efficiency, the depth to which this can be achieved, and the time scale required is estimated for each type of poulticing system, to gain a better understanding of their working properties and performance. Finally, the pros, cons and limitations of desalination treatments are discussed. 相似文献

Dynamic behaviour of soils used for natural turf sports surfaces 总被引:1,自引:0,他引:1
The modulus and damping properties of soils in compression are a function of soil type, water content, stress history and
loading rate. To model human–surface interaction with natural turf sports surfaces, stiffness and damping properties must
be determined at dynamic loading rates. Two contrasting soil types, a Sand and a Clay Loam, commonly used in sports surfaces
were loaded uniaxially to 2 kN at loading rates between 0.6 and 6 kN s−1 in modified dynamic soil testing apparatus. Soils were compacted prior to loading but initial cycles resulted in viscoplastic
deformation, with strain accumulation with repeated cycles of loading. Ultimately a resilient, viscoelastic steady-state equilibrium
with loading was established. Resilient modulus and damping ratio varied with soil type, water content, stress history and
increased significantly with loading rate. The resilient modulus of the Sand soil, typical of modern free-draining sand construction
natural turf sports surfaces, was significantly greater than that of a Clay Loam soil more characteristic of traditional natural
turf surfaces; reducing water content caused an increase in modulus and a decrease in damping ratio in the Clay Loam soil.
Determination of these properties provides initial data for the modelling natural turf surface behaviour in terms of both
ball and human interactions, with further research required to determine the effect of both grass roots and leaves on mechanical
behaviour. 相似文献

In the current research, we examined whether promoting an inclusive national ingroup that includes both immigrants and nonimmigrants would improve attitudes toward immigrants and immigration among members of receiving societies. We also determined whether one's nation of citizenship and individual differences in social dominance orientation would moderate the effects. Participants were 126 Canadian students and 282 German students, who completed a measure of social dominance orientation and were then asked to respond to a series of questions designed to heighten the salience of national identity (national identity), promote a national ingroup that includes immigrants (common national ingroup), or irrelevant questions (control). The dependent measures included attitudes toward immigrants and immigration, and subtle prejudice toward immigrants. Results revealed that the manipulation of a common national ingroup successfully promoted more positive attitudes toward immigrants and immigration among higher social dominance oriented Canadian participants, but tended to have detrimental effects on the attitudes of higher social dominance oriented German participants. Results are discussed in terms of the importance of considering the context in which groups are situated, as well as implications for developing strategies to promote harmony between immigrants and members of receiving societies. 相似文献
