Children living in poverty are 1.3 times as likely as non‐poor children to experience reading difficulties and lack key oral experiences that contribute to early literacy development. The purpose of this research was to study the effects of viewing commercially available educational television with closed captions. Seventy second‐ and third‐grade economically disadvantaged children living in urban locations participated in this experimental research design. Children were randomly assigned to view videos with or without closed captions. Captions helped children recognise and read more words, identify the meaning of those words, generate inferences regarding programme content and transfer these skills to a normative code‐related skill task. Risk status moderated word recognition performance: those at risk benefited from captions while those who were not at risk recognised more words when captions were absent. 相似文献

In this paper we present a new methodology for detecting differential item functioning (DIF). We introduce a DIF model, called the random item mixture (RIM), that is based on a Rasch model with random item difficulties (besides the common random person abilities). In addition, a mixture model is assumed for the item difficulties such that the items may belong to one of two classes: a DIF or a non-DIF class. The crucial difference between the DIF class and the non-DIF class is that the item difficulties in the DIF class may differ according to the observed person groups while they are equal across the person groups for the items from the non-DIF class. Statistical inference for the RIM is carried out in a Bayesian framework. The performance of the RIM is evaluated using a simulation study in which it is compared with traditional procedures, like the likelihood ratio test, the Mantel-Haenszel procedure and the standardized p -DIF procedure. In this comparison, the RIM performs better than the other methods. Finally, the usefulness of the model is also demonstrated on a real life data set. 相似文献

Changing lifestyles are having an impact on programs for young children. Recently these programs have adjusted to meet the
needs of children from one-parent homes, broken homes, and teen homes. Now children of mixed racial and ethnic backgrounds
are an ever-increasing phenomenon in programs.

In order to evaluate the gender differences on the experience of aging, 142 individuals 50 years of age and older completed an interview regarding experiences with another individual conveying the message that they were “old.” Interviewees were asked about the type of situation, the age and gender of the response person, and the perceived intent and feelings associated with the experience. Results showed that 72.3% of the experiences could be classified into one of three categories: discount/benefit, physical features/appearance, and performance. While no gender differences were found in the location/setting of the incident, the response person, or the age of the response person, findings indicated that for men, the incident was classified as a “benefit/discount,” while for women it was classified as “physical features/appearance.” In addition, the presumed intent of the situation was viewed as negative and hurtful by women, and both genders reported that the incident made them feel self-conscious and/or elicited a negative self-assessment. These results illustrate that the self-reported experiences that make one feel old and potentially change an individual's identity are important to understand in the context of growing older as a gendered experience. 相似文献
