The development of reading skills in language minority (LM) learners, particularly during the middle school years, remains
unclear despite the increasing need for educators to serve this rapidly growing population. In this study, the English reading
comprehension growth of middle school LM learners was investigated using a longitudinal design and the simple view of reading
as a theoretical framework. Students were assessed at four time points between fifth and seventh grades on standardized measures
of listening comprehension, word reading, and reading comprehension. Individual growth modeling revealed that both listening
comprehension and word reading assessed in fifth grade predicted the elevation of students’ developmental trajectories in
reading comprehension. However, neither skill predicted students’ growth in reading comprehension, and there was no significant
variation across children in growth rates, indicating that students in seventh grade remained on a trajectory established
in fifth grade. The implications of the slowing rate of reading comprehension development during the middle school years are
discussed. 相似文献

Using Necessary Information to Identify Item Dependence in Passage-Based Reading Comprehension Tests
Applications of traditional unidimensional item response theory models to passage-based reading comprehension assessment data have been criticized based on potential violations of local independence. However, simple rules for determining dependency, such as including all items associated with a particular passage, may overestimate the dependency that actually exists among the items. The current study proposed a more refined method based on cognitive principles and substantive theories to determine those items that pose a threat. Specifically, the use of common necessary information from text was examined as a contributor of local dependence. Cognitively similar item pairs, those with connected necessary information, had higher local dependence values than item pairs with no connected necessary information. Results suggest that focusing on necessary information may be useful to some extent for understanding and managing item dependence for passage-based reading comprehension tests. 相似文献

Strong arguments have been made for early intervention for child problems, stating that early is more effective than later, as the brain is more malleable, and costs are lower. However, there is scant evidence from trials to support this hypothesis, which we therefore tested in two well-powered, state-of-the-art meta-analyses with complementary strengths: (a) Individual participant data (IPD) meta-analysis of European trials of Incredible Years parenting intervention (k = 13, n = 1696; age = 2–11); (b) Larger, trial-level robust variance estimation meta-analysis of a wider range of parenting programs (k = 156, n = 13,378, Mage = 2–10) for reducing disruptive behavior. Both analyses found no evidence that intervention earlier in childhood was more effective; programs targeted at a narrower age range were no more effective than general ones. 相似文献

This study aims to determine if biomechanically informed injury prevention training can reduce associated factors of anterior cruciate ligament injury risk among a general female athletic population. Female community-level team sport athletes, split into intervention (n = 8) and comparison groups (n = 10), completed a sidestepping movement assessment prior to and following a 9-week training period, in which kinetic, kinematic and neuromuscular data were collected. The intervention group completed a biomechanically informed training protocol, consisting of plyometric, resistance and balance exercises, adjunct to normal training, for 15–20 min twice a week. Following the 9-week intervention, total activation of the muscles crossing the knee (n = 7) decreased for both the training (? ?15.02%, d = 0.45) and comparison (? ?9.68%, d = 0.47) groups. This decrease was accompanied by elevated peak knee valgus (? +27.78%, d = ?0.36) and internal rotation moments (? +37.50%, d = ?0.56) in the comparison group, suggesting that female community athletes are at an increased risk of injury after a season of play. Peak knee valgus and internal rotation knee moments among athletes who participated in training intervention did not change over the intervention period. Results suggest participation in a biomechanically informed training intervention may mitigate the apparent deleterious effects of community-level sport participation. 相似文献

A dynamic model of the breast during exercise 总被引:1,自引:1,他引:0
The aim of this paper is to develop a method to determine the material characteristics of bras that could limit breast motion
during exercise. A single participant ran on a treadmill at 10 km h−1 wearing either a sports bra, an everyday bra or no bra. The relative motion between the suprasternal notch and the breast
was recorded using a passive marker system at 200 Hz and was modelled as forced damped-harmonic motion with a linear spring
and damper, with the driving force provided by the suprasternal notch. The spring and damper values were found by matching
the model to the experimental data. It was found that both the damping and stiffness values increased with the use of an everyday
bra, and increased further still with the use of a sports bra. The stiffness parameter, however, was shown to be the most
important criterion for minimisation of the breast motion. The model predicted that an increase in breast mass from 100 to
700 g (a 32A-cup to a 32F-cup) increased the vertical motion of the unsupported breast by around 70% when running and 30%
when walking. This was reduced with an everyday bra and further reduced with the high stiffness sports bra. Although predictions
were sensible, the model requires further verification with a cohort of participants. 相似文献

This study focuses on a secondary English classroom in an East London school, and the multimodal nature of the students’ construction of the literary heritage text Macbeth, specifically in their dramatic reinterpretation of Act 1, Scene 7, where Lady Macbeth persuades Macbeth to pursue his ambitions and kill the current king, Duncan. From this classroom event, this study goes on to explore how a social semiotic reading can reveal insights into school students’ learning and recreation of this text. 相似文献
