This article examines the complex connections between literacy practices, the use of information and communication technologies (ICTs) and disadvantage. It reports the findings of a year-long study which investigated the ways in which four families use ICTs to engage with formal and informal literacy learning in home and school settings. The research set out to explore what it is about computer-mediated literacy practices at home and at school in disadvantaged communities that makes a difference in school success. The findings demonstrate that the 'socialisation' of the technology--its appropriation into existing family norms, values and lifestyles--varied from family to family. Having access to ICTs at home was not sufficient for the young people and their families to overcome the so-called 'digital divide'. The article concludes that old inequalities have not disappeared, but are playing out in new ways in the context of the networked society. 相似文献

An approach to essay grading based on signal detection theory (SDT) is presented. SDT offers a basis for understanding rater behavior with respect to the scoring of construct responses, in that it provides a theory of psychological processes underlying the raters' behavior. The approach also provides measures of the precision of the raters and the accuracy of classifications. An application of latent class SDT to essay grading is detailed, and similarities to and differences from item response theory (IRT) are noted. The validity and utility of classifications obtained from the SDT model and scores obtained from IRT models are compared. Validity coefficients were found to be about equal in magnitude across SDT and IRT models. Results from a simulation study of a 5-class SDT model with eight raters are also presented. 相似文献

Researchers investigating answer changing have consistently found the preponderance of changes on objective items to be from wrong to right, but little is understood about the mechanisms involved in this phenomenon. In this study, personal interviews were combined with instruction in answer-changing research to investigate further the processes involved in answer changing. Students changed answers and gained from changing, with those in the upper two thirds of the classes gaining the most. Each test-taking strategy produced a mean gain, but particular strategies were not significantly correlated with percentage of gain or percentage of change. Most students reported changing answers for thoughtful reasons such as rereading, rethinking, or remembering more information; very few changes were due to clerical errors. For each reason, most changes were wrong-to-right. We conclude that reconsideration of test items is probably underestimated in answer-changing studies. The role of memory should be considered in why people change and in how successful they judge their changing to have been. 相似文献

Supplemental instruction classes have been shown in many studies to enhance performance in the supported courses and even to improve graduation rates. Generally, there has been little evidence of a differential impact on students from different ethnic/racial backgrounds. At San Francisco State University, however, supplemental instruction in the Introductory Biology I class is associated with even more dramatic gains among students from underrepresented minority populations than the gains found among their peers. These gains do not seem to be the product of better students availing themselves of supplemental instruction or other outside factors. The Introductory Biology I class consists of a team-taught lecture component, taught in a large lecture classroom, and a laboratory component where students participate in smaller lab sections. Students are expected to master an understanding of basic concepts, content, and vocabulary in biology as well as gain laboratory investigation skills and experience applying scientific methodology. In this context, supplemental instruction classes are cooperative learning environments where students participate in learning activities that complement the course material, focusing on student misconceptions and difficulties, construction of a scaffolded knowledge base, applications involving problem solving, and articulation of constructs with peers. 相似文献

Income is not enough: incorporating material hardship into models of income associations with parenting and child development 总被引:2,自引:0,他引:2
Although research has clearly established that low family income has negative impacts on children's cognitive skills and social-emotional competence, less often is a family's experience of material hardship considered. Using the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (N=21,255), this study examined dual components of family income and material hardship along with parent mediators of stress, positive parenting, and investment as predictors of 6-year-old children's cognitive skills and social-emotional competence. Support was found for a model that identified unique parent-mediated paths from income to cognitive skills and from income and material hardship to social-emotional competence. The findings have implications for future study of family income and child development and for identification of promising targets for policy intervention. 相似文献

For this study, information on Who Bullies Who was collected from 54 school classes with 918 children (M age = 11) and 13,606 dyadic relations. Bullying and victimization were viewed separately from the point of view of the bully and the victim. The two perspectives were highly complementary. The probability of a bully-victim relationship was higher if the bully was more dominant than the victim, and if the victim was more vulnerable than the bully and more rejected by the class. In a bully-victim dyad, boys were more often the bullies. There was no finding of sex effect for victimization. Liking reduced and disliking increased the probability of a bully-victim relationship. 相似文献

本演讲探讨了欧洲早期艺复兴期间(大约1350—1700)为解读亚里士多德的(修辞学)中的论述所做出的努力,讨论了欧洲的注释在理解亚里士多德的(修辞学〉中所遇到的困难,关注了当时学意料之外的某些论争,并力图阐释引起这些论争的原因。作认为,人们力图阐释关于一种化的论述并力图从另一种化的需求和兴趣来解读这种论述的努力对中美两国具有重要意义,这些阐释所可能引发的结果也具有积极意义。作的这种解读对当今世界——对中国和“西方”国家富有更为广泛的意义——因为他在试图解读产生于一种化而被转译到另一种化的修辞学和传播学理论。作指出,在欧洲艺复兴时期,人们相信修辞学和社会很大程度上是一回事。修辞学能够使人们避免暴力、摆脱兽性,使许多不同人的思想统一起来,促成一种包容各种矛盾的和谐社会。修辞学使我们变得明。[第一段] 相似文献
