介绍如何使用HTML 5中的video元素来播放视频文件,如何利用video元素的各种属性、事件与方法来定制属于自己的网页视频播放器。虽然目前很多主流浏览器都针对video元素提供了一个视频播放控件(在代码中可以通过使用video元素的controls属性来显示该控件),但是很多时候这个默认的播放控件并不能满足开发者或用户的某些特定需求,这就需要通过自己定义视频播放器来满足这种需求。 相似文献

Composite reading scores obtained from parents of 125 reading-disabled children and 125 matched control children who participated in the Colorado Family Reading Study were used to test the validity of self-reported reading problems. Parents who reported that they encountered serious difficulty learning to read had significantly lower reading scores than did those who reported no positive history of reading problems. Moreover, this difference was larger for parents of reading-disabled children than for those of controls. Thus, parental self-reports provide a valid index of reading problems. 相似文献

OBJECTIVE: This study aimed to profile the psychological and psychosocial characteristics of a group of Irish adolescents who had sexually abused other youngsters. METHOD: Levels of behavior problems, personal adjustment, anger management, and psychosocial adjustment were compared in 27 Irish adolescents with a history of sexually abusing another youngster (SA group), 20 clinical controls who had significant behavioral problems but no history of sexual offending (CC group), and 29 normal controls who were without significant psychological problems (NC group). Measures used included the Child Behavior Checklist (CBCL), the Youth Self-Report Form (YSR), selected scales from Beckett (1997) Adolescent Sex Offender Assessment Pack (ASOAP), and the Family Environment Scale (FES). RESULTS: Compared with the CC group, the SA group displayed fewer problems overall on the CBCL and the YSR. The SA group showed problems with self-esteem, emotional loneliness, and perspective-taking similar to those of the CC group, but their impulsivity scores were similar to those of the NC group. The locus of control scores of the SA group fell between those of the CC and NC groups. The SA group showed an anger management profile that fell at an intermediate position between those of the NC and CC groups. The SA group showed problematic family functioning in the areas of expressiveness, behavior control, and social support, similar to those of the CC group. Their difficulties with family cohesion were less severe than those of the CC group but worse than those of the NC group. CONCLUSIONS: Overall, the psychological adjustment of adolescents with a history of sexually abusing others was more problematic than that of normal controls but less problematic than that of youngsters who had significant behavioral problems but no history of sexual offending. 相似文献

A form of socially assisted group learning based on a modified version of reciprocal teaching for mathematics (Campione, Brown, & Connell, 1988) was evaluated in terms of its effectiveness in promoting fourth graders' solution of complex 2-step word problems. The emphasis in this method is for an adult tutor to elicit solution suggestions from students and to explore the multiple solutions in seeking group agreement. The method focuses attention both on world representations underlying numbers and on transfer of problem solution planning skills to children over time. The results were compared with those from a modeling-reinforcement tutoring control condition and a classroom activity control in a 10-week study of fourth graders' solution of 4 types of 2-step math word problems, constructed to avoid keywords. Individuals who received either type of training earned higher scores for all problem types than did controls on quizzes; children in the modified reciprocal teaching condition outscored those in the modeling condition on problems that required information to be added from outside the problem and on a quiz of mixed problem types. Subsequent analysis of solutions and videotaped math behaviors suggested that those in the socially assisted learning condition used labeled representations in problem solving more effectively and deduced implied information earlier and more often than those in the modeling condition. 相似文献

A large body of evidence shows that many of the academic difficulties Attention Deficit Hyperactivity Disorder (ADHD) children
have may be related to their problems in executive control. However, the particular case of expressive writing has not been
deeply explored. The present study examines the typical school exercise of writing a letter. Participants were 33 third, fourth,
and fifth graders referred by teachers for the presence of ADHD symptoms plus 33 controls. The task consisted of describing
an aspect of their life in the form of a letter. Texts of ADHD children were poorer than those of the controls for structure,
vocabulary, grammar, length, and accuracy. Furthermore, the difference persisted even when a guide was used to support the
writing task. However, the two groups were not significantly different in a metacognitive test measuring knowledge on critical
factors affecting expressive writing. Results show that ADHD children may encounter severe difficulties in expressive writing
that are not due to differences in knowledge about how to write. Educational implications are discussed. 相似文献

Research findings: In order to assess the relations between sleep problems and temperament in infants, temperament ratings of 63 toddlers who presented with night waking problems were compared to those of 35 non-referred toddlers. An objective method to assess sleep patterns was used to validate the distinct sleep patterns of the two groups prior to the comparison of the temperament scales. Measures included: Toddler Temperament Questionnaire (TTQ) and the child's scales of the Parental Stress Index (PSI). On the TTQ, Night Wakers were rated as having lower sensory thresholds compared to the controls. Night Wakers were also rated as less adaptive than the controls. On the PSI, Night Wakers were rated as more distractible; less reinforcing; less adaptive and more demanding. Practice or policy: The results suggest that sleep disturbances in early childhood are closely associated with negative maternal perceptions of child temperament. It is proposed that early detection and treatment of sleep problems during early childhood may prevent some of the associated negative behavioral consequences. 相似文献

The Turner syndrome: cognitive deficits, affective discrimination, and behavior problems 总被引：5，自引：0，他引：5
Individuals with sex chromosomal anomalies are known to be at increased risk for learning problems and in some cases social or behavioral problems. Girls with an absent or structurally abnormal second sex chromosome (the Turner syndrome) have been found to have cognitive problem solving deficits and immature, inadequate social relationships. The present study attempted to link cognitive and social problems by assessing the girls' ability to process affective cues. 17 girls with karyotypes consistent with a diagnosis of Turner syndrome were compared to a group of 16 short-stature girls of comparable age, verbal intelligence scores, height, and family socioeconomic status on the Affective Discrimination Task, which required interpretation of affective intention from facial expression. The results revealed that the Turner syndrome girls were less accurate at inferring facial affect than the short-stature controls. Analyses revealed that the Turner syndrome girls performed more poorly on spatial, attentional, and short-term memory cognitive tasks and had more psychosocial problems than the short-stature controls. Ability to discriminate facial affect may be another area of cognitive weakness for girls with the Turner syndrome and may underlie the psychosocial problems found in this sample. 相似文献

Objective: Left-behind children have a high incidence of behavioral problems in some Eastern countries, especially China. We sought to assess the combined effects of physical neglect, a major embodiment of the left-behind phenomenon, and the trauma of being left behind on subsequent behavioral problems.Method: 776 children (including 600 left-behind children) aged 12–16 years were chosen by cluster sampling in rural China. The Childhood Trauma Questionnaire-Short Form and the Conners Teacher Rating Scale were used to evaluate physical neglect and behavioral problems.Results: Left-behind children experienced more physical neglect (mean difference = 0.63; 95%CI 0.15–1.10; P = 0.01) and were more inattentive (mean difference=0.11; 95%CI 0.03–0.19; P = 0.009) than non-left-behind children. Physically neglected left-behind children had higher scores for conduct problems, inattention, and hyperactivity index than non-left-behind without physical neglect group (P < 0.05 for each). Among left-behind children, physical neglect group had significantly more conduct problems than those of controls (mean difference=0.14; 95%CI 0.05–0.23; P = 0.008). Physically neglected non-left-behind children had higher scores for conduct problems than those of left-behind children without physical neglect (mean difference=0.31; 95%CI 0.13–0.47; P = 0.003). Among physically neglected children, left-behind children had significantly higher scores for inattention than those of non-left-behind children (mean difference=0.13; 95%CI 0.04–0.22; P = 0.037).Conclusion: Left-behind children have more behavioral problems than non-left-behind children. Physical neglect may result in more severe conduct problems than those associated with staying behind, and staying behind may lead to inattention. Exposure to both may lead to more obvious behavioral problems. Therefore, we should accord more attention to physically neglected and left-behind children. 相似文献

The association of reading disability with perceptuomotor problems has had a chequered history. This study examines the relationship between a new test of ocular dominance and reading and spelling ability in a group of 323 schoolchildren. Similar rates for unfixed ocular dominance were found for poor readers as in comparable studies. The rates of unstable ocular dominance did not differ between those with reading and spelling difficulties and controls. These findings in a ‘blind’ study question the role of this test of eye dominance as a diagnosis of ‘dyslexia’. 相似文献
