This study draws on recent research on the central role of representation in learning. While there has been considerable research
on students’ understanding of evaporation, the representational issues entailed in this understanding have not been investigated
in depth. The study explored students’ engagement with evaporation phenomena through various representational modes. The study
indicates how a focus on representation can provide fresh insights into the conceptual task involved in learning science through
an investigation of students’ responses to a structured classroom sequence and subsequent interviews over a year. A case study
of one child’s learning demonstrates the way conceptual advances are integrally connected with the development of representational
modes. The findings suggest that teacher-mediated negotiation of representational issues as students construct different modal
accounts can support enriched learning by enabling both (a) richer conceptual understanding by students, and (b) enhanced
teacher insights into students’ thinking. 相似文献

The purpose of this study is threefold: first, to describe the characteristics of child abuse and neglect on a major Indian reservation; second, to examine the impact of a community team approach to child abuse and neglect as measured by the incidence of reported abuse and neglect and admissions for emergency foster care; and third, to make recommendations for actions to close the gaps in child welfare services to Indian children living on reservations. 相似文献

ABSTRACTThe health, wellbeing and employability of university students are key considerations within higher education. In response, interest in student resilience is on the rise. Reviews of contemporary resilience literature highlight both conceptual and methodological weaknesses, issues which hamper attempts to design effective resilience interventions. To inform the design of a student resilience program, to be piloted at three Australian universities, a scoping review of resilience specific to the higher education context was undertaken. Searches of three electronic databases (PsychINFO, CINAHL and ProQuest) were conducted. Seventy-two peer-reviewed articles published between 2007 and 2017 were included in the review. While the review reaffirms the conceptual and methodological issues found in previous resilience research, it provides a useful critique of key issues in relation to university student resilience and interventions to enhance students’ resilience. Recommendations for educators and researchers are provided. 相似文献

An experiment with 72 three-year-olds investigated whether encoding events while seeing iconic gestures boosts children's memory representation of these events. The events, shown in videos of actors moving in an unusual manner, were presented with either iconic gestures depicting how the actors performed these actions, interactive gestures, or no gesture. In a recognition memory task, children in the iconic gesture condition remembered actors and actions better than children in the control conditions. Iconic gestures were categorized based on how much of the actors was represented by the hands (feet, legs, or body). Only iconic hand-as-body gestures boosted actor memory. Thus, seeing iconic gestures while encoding events facilitates children's memory of those aspects of events that are schematically highlighted by gesture. 相似文献

The influence of sociocultural factors (ethnicity, socioeconomic status, father absence, and family size) on special education eligibility was examined for three ethnic groups. A multiple regression procedure was used to analyze the data on 300 students referred for evaluation and found to be either not eligible for services or eligible for services as mentally retarded or learning disabled. Results indicated that only socioeconomic status and ethnicity made a significant contribution to the prediction of all three groups. Individually, father absence and family size did not contribute to the prediction of special education eligibility. Results of this study suggest that legislative mandates to control for sociocultural factors in the determination of special education eligibility have been only partially successful. 相似文献

Funding agencies in Canada are attempting to break down the organizational boundaries between disciplines to promote interdisciplinary
research and foster the integration of the social sciences into the health research field. This paper explores the extent
to which biomedical and clinician scientists’ perceptions of social science research operate as a cultural boundary to the
inclusion of social scientists into this field. Results indicated that cultural boundaries may impede social scientists’ entry
into the health research field through three modalities: (1) biomedical and clinician scientists’ unfavourable and ambivalent
posture towards social science research; (2) their opposition to a resource increase for the social sciences; and (3) clinician
scientists procedural assessment criteria for social science. The paper also discusses the merits and limitations of Tom Gieryn’s
concept of boundary-work for studying social dynamics within the field of science.
