Developmental trajectories of personal and collective self-concept were examined among American Indian adolescents. Personal self-concept (self-esteem) and collective self-concept (American Indian identity, Euro-American identity, community-mindedness) were assessed 6 times over 3 years in 4 cohorts of adolescents from 3 American Indian cultural groups (N=1,252). An accelerated longitudinal design was used to estimate developmental trajectories from 14 to 19 years; parallel-process and covariate models were used to examine variation in trajectories. Both personal and collective self-concepts were generally positive and showed small gains; they were moderately related to one another and differentially related to cultural group, gender, and perceived social support. The findings highlight the complexity of self-concept for American Indian youth and the significance of both personal and collective identity.  相似文献

The purpose of this longitudinal case study was to closely examine one deaf child's experience with a cochlear implant and his speech, language, and communication skills from kindergarten through middle and high school using both developmental and sociocultural frameworks. The target child was one of the first children to receive a cochlear implant in the United States in 1988, when he was 5 years of age. The developmental analysis revealed that prior to receiving a cochlear implant the child demonstrated profound delays in speech and language skill development. His speech and language skills grew slowly during the first 3-4 years following implantation, very rapidly from about 5 through 7 years postimplantation, then slowed to rates that were highly similar to same-age peers with normal hearing. The sociocultural analysis revealed that the child's communicative competence improved; that he used sign language but use of sign language decreased as his oral communication skills improved; that as his oral communication skills improved, the adults talked and directed the topic of conversation less frequently; and that topics became less concrete and more personal over time. The results of this study indicate that we may learn more about how to support children who use cochlear implants by examining what they are saying as well as how they are saying it.  相似文献

BACKGROUND: The Internet is a valuable information tool, but users often struggle to locate good quality information from within the vast amount of information available. OBJECTIVE: The aim of the study was to identify the online information resources available to assist students develop Internet searching skills, and to explore the students' priorities in online guides. METHODS: A qualitative approach was adopted with two phases. The first was a structured search of available online study skills resources. The second comprised 10 group interviews with a total of 60 students at all stages of five undergraduate health and social care related courses at a UK university. RESULTS: The study found that there were good online guides available, but that, perversely, the better guides tended to require the best searching skills to locate them. A few students were enthusiastic about using online support, however the majority felt that if they had the skills to locate such resources they wouldn't use a study guide to improve these skills, and if they did not have the skills they would not think of using an online guide to develop them. CONCLUSIONS: Students wanted assistance when they had problems or questions, rather than sites that offered structured learning experiences. Personal support rather than virtual support was also considered to be most important to the students in this study.  相似文献

<正> 近些年来,国內许多图书情报部门相继建立起自己的国际联机文献检索终端系统。其中绝大多数均采用电传机作为联机哑终端。由于过低的传输波特率,使得联机的时间无味地拖长。显然这对检索结果毫无益处,却给用戶增加了很高的检索费用。加之检索人员业务水平的限制,宣传不力等等原因,使得大批用戶根本不敢问津,许多单位不惜外汇重金投资,但使用效益却非常低。目前,国外绝大多数的联机哑终端已为微机所作的智能终端取代。本文就如何使用微型计算机进行联机检索作一较为详细的叙述,旨在为那些准备或正在进行向微机转化的同行们提供一些帮助。  相似文献

The objective of this study was to describe prevalent informal sources of information about sex and examine associations between informal sources of information about sex and sexual risk outcomes among sexually experienced adolescents. Work involved the secondary analysis of data from the Minnesota Student Survey, a statewide survey to monitor priority risk and protective health behaviors. The study sample included 22,828 sexually experienced adolescents aged 13–20 years. Multivariate logistic regression analyses examined associations between adolescents' informal sources of information about sex and three sexual risk outcomes. Peers and siblings were the most commonly reported source of information about sex. Ninth-graders who reported parents or parents plus peers/siblings as a source of information about sex had significantly lower odds of having multiple sex partners in the past year. Ninth-graders who reported any informal source of information about sex had significantly lower odds of unprotected intercourse at last sex. Ninth-graders and 12th-graders who reported any informal source of information about sex had significantly lower odds of lifetime pregnancy involvement. Findings suggest information about sex from people in adolescents' everyday lives has the potential to diminish the likelihood of involvement in sexual risk behaviors. To maximize effectiveness, formal sex education programs should engage informal sources of information about sex in adolescents' everyday lives.  相似文献

Tzipora Jochsberger (1920–) educator, composer, and musicologist, dreamed of using the arts to introduce Jews to the richness of their heritage. The founder and director of the Hebrew Arts School in New York (1952–1986), Jochsberger's contributions deserve the attention of Jewish educators and artists who are looking to the arts to address the diverse needs of Jewish learners of all ages. A student of the Jewish Teachers’ Seminary in Wurzburg, Germany, Jochsberger was offered an opportunity that would not only save her life, but determine its direction as well. Using interviews, archival data, and Jochsberger's papers both published and unpublished, I have tried to examine her educational vision for the school she nurtured for more than thirty years, discovering in the process that the school was the product of a fortuitous shiddukh: the dream of a gifted Holocaust survivor and the idealism of American Hebraists, the ideologues of Ha'Noar Ha'lvri.  相似文献

In the field that investigates infectious brain diseases such as mad cow disease, the verbal and visual packaging of scientific visuals associated with identifying the agent, prion, its processes, and structure served the community ritual of establishing belief in a highly unorthodox phenomenon. Visual promotion fed into cultural expectations of single agents and simple processes, even though the actual agency and disease process have proven highly complex and perhaps unknowable.  相似文献

Public schools in the United States are predicated upon some common, albeit contested, understanding of a “normal” child. Such an identity comes with corresponding rules of behavior. In this study, we use identity politics as the primary lens through which to interpret the experiences of students at an alternative middle and high school. Through ethnographic field observational data and student interviews over a four-month period, we examine student narratives to inform the theoretical framework of this research. We conclude that the alternative school in this case study is a stigmatized space for students with spoiled identities (Goffman, 1963 Goffman, E. 1963. Stigma: Notes on the management of spoiled identity, Englewood Cliffs, NJ: Prentice-Hall.  [Google Scholar]). We offer implications for alternative schools in general and suggest that their design, by definition, can reinforce the stigmatized identity and its corresponding “deviant” behavior.  相似文献
