A stress management program was evaluated in sixth-grade classes of an urban public and a suburban parochial school. Sample 1, from the urban public school, and Sample 2, from the suburban parochial school, received pre- and posttests. Sample 3, from the suburban parochial school, was divided into pretest-only and posttest-only groups. Six self-esteem and 1 each stress and social-skills children's self-ratings and 1 each teachers' ratings of children's overall stress management and stress measures were used. All 10 measures showed improvement in the Samples 1 and 2 independently. Findings in Sample 2 replicated the positive effects in Sample 1. In both sixth-grade classes, children's stress level (self- and teachers' ratings), children's social skills and self-esteem self-ratings, and teachers' ratings of children's stress management skills improved significantly. Sample 3 posttest-only group scores did not differ significantly from the posttest scores of Sample 1 and 2 children. Rival hypotheses (e.g., history, maturation, testing) appeared implausible. Results support using skills-oriented stress management programs in regular grade school classes. 相似文献

Much literature has been devoted to theoretical explanations of the learning processes of older adults and to the methods of teaching best utilized in older populations. However, there has been less focus on the education of older adults who reside in assisted and independent living communities (AICs), especially with regards to information and communication technology (ICT) education. The purpose of this study is to determine whether participants' attitudes and views towards computers and the Internet are affected as a result of participating in an eight-week training program designed to enhance computer and Internet use among older adults in such communities. Specifically, we examine if ICT education specially designed for AIC residents results in more positive attitudes towards ICTs and a perceived decrease in factors that may limit or prevent computer and Internet use. We discuss the implications of these results for enhancing the quality of life for older adults in AICs and make recommendations for those seeking to decrease digital inequality among older adults in these communities through their own ICT classes. 相似文献

This study replicates research on the efficacy of a repeated reading intervention with word-level instruction for students in Grades 2 and 3 with low to moderate fluency skills, examines differences between treatment implementers, and tests unique contributions of treatment-related variables on outcomes. Students from 13 schools were randomly assigned to dyads; dyads were randomly assigned to treatment or control conditions. Schools were matched into treatment implementer groups (teachers or paraeducators) at study onset. Tutoring occurred during school hours for 15 weeks (M = 25.5 hr). Multilevel model results showed treatment students (n = 98) gained more than controls (n = 104) on measures of letter-sound knowledge (d = .41), fluency (d = .37–.38), and comprehension (d = .30–.31); students tutored by teachers gained more than their paraeducator-tutored peers on word reading and fluency. Finally, dyads tutored with greater fidelity gained more in word reading and fluency; dyads that read more complex words in their texts gained less on letter-sounds, fluency, and comprehension. 相似文献

This study examines the nature of teacher participation in the context of a video club. Video clubs are professional development meetings in which teachers watch and discuss excerpts of video from their classrooms. In this study, I adopt a situative perspective to examine how teachers develop in their participation to accomplish the goals of the video club. In particular, I examine the roles participants play and explore teachers' participation in four roles that correspond with key goals of the video club. Analysis revealed that teachers' participation shifted in qualitatively different ways over time, with the teachers coming to prompt the group to discuss student mathematical thinking, to propose a variety of interpretations of student ideas, to build on one another's ideas, and to challenge one another's thinking in order to advance the group's conversations. This analysis suggests that the group learned how to participate in roles central to accomplishing the goals of the video club. Studying teacher learning through a lens of participation provides insight into the ways in which teachers coordinate themselves to engage with the goals of professional development and has implications for designing professional development that helps teachers develop practices for teaching mathematics for understanding. 相似文献

Using Total Communication With Young Children With Down Syndrome: A Literature Review and Case Study
This paper presents a literature review regarding language abilities of children with Down syndrome and presents a case study concerning the effectiveness of using Total Communication with a young child with Down syndrome. The prevalence of expressive language delays in children with Down syndrome highlights the need to develop early interventions to promote language development. The existing literature on the usefulness of Total Communication as an intervention method with children and adults with special needs is documented and a rationale for the use of Total Communication with children with Down syndrome is presented. In the case study, a single subject simultaneous treatment design was used which involved introducing 20 words during free play (10 oral and 10 Total Communication), which were matched on phonetic complexity and reinforcement value. Results indicated that comprehension was not differentially affected by the type of communication approach used. However, expressively the child was able to use manual signs many months before any understandable words were produced. The use of manual signs did not inhibit use of speech. The results of this case study suggest that the early use of Total Communication can be an effective transitional mode of communication for at least some children with Down syndrome. Further research is needed to explore individual differences between children with Down syndrome and to identify factors that predict those children who benefit most from the use of Total Communication. 相似文献

The aim of this investigation was to examine the role of social relationships in the home as predictors of social functioning in the first years of school. Longitudinal data gathered on 156 children from urban, low-income families were used to examine the unique contributions of mother-child attachment classification at ages 1 and 2 years, the child's relationship with another adult caregiver, the child's closeness to a sibling, and the child's status in the family relative to siblings between ages 3 and 4 years, to teacher reports of their own relationship to the child and the child's social skills in the classroom and peer relations. The role of family-based relationships as possible protective factors for children at social or demographic risk for problems in school was also tested. Results indicate that quality of different family relationships provides relatively independent and complementary information about early social functioning in school, with more limited evidence for compensatory or protective processes at work. 相似文献

This article reports the results of research to determine if a significant interactive effect exists between students' lingual background (English as a primary language [EPL] versus English as a secondary language [ESL]) and question format on students' examination scores. Students were administered examinations made up of four subtests covering the same subject matter. The subtests were composed of four question formats: multiple choice quantitative, multiple choice theoretical, open-ended quantitative, and open-ended essay questions. Based on analysis of variance and analysis of covariance, significant differences were observed between EPL and ESL students depending on the type of question on the examination. 相似文献
