The authors of this article are members of a subcommittee of the Mathematical Association's Teaching Committee. The subcommittee's brief is to prepare a pack of materials for primary school teachers to help them to teach Data Handling in the National Curriculum at Key Stages 1 and 2. This report is based on a review of existing mathematics schemes undertaken as part of the subcommittee's work.  相似文献

Direct and indirect measures were used to compare the written language abilities of three groups of college students: two with learning disabilities and one without learning disabilities. Main effects were found for group, but not gender. Differences between nonlearning disabled students (NLD) and those with learning disabilities (LD) in writing were evident on both types of measures. Performance by LD students with disabilities in an area other than writing differed depending on the type of measure and often was no different from either of the other two groups. The combined use of direct and indirect measures appeared most effective for examining the complexities of writing produced by all groups.  相似文献

This study focused on a cohousing community's use of consensus to make a decision about surfacing a parking area. It revealed that the community's use of consensus decision making allowed the residents to balance three goals: making an appropriate decision, meeting members' needs, and maintaining the community's well-being. Reaching agreement, however, was complicated by members' value differences and discontinuity in their participation. The analysis of this case reveals three qualities characteristic of the enactment of consensus: the role of structured communication within and between group meetings, a tension between maintaining process openness and reaching decision closure, and the expectation that group members will work within the consensus process. The analysis also highlights the importance of timing in the interpretation of conflict in a consensus-oriented group and the role of process change when a group reaches the limits of members' commitment to consensus.  相似文献

This study examines mistreatment through the perspectives of employees with different cultural backgrounds and positions in order to understand the ways in which some voices are muted and others are privileged. Mistreatment is interactional, distributive, procedural, or systemic abuse of employees taking place at both interpersonal and institutional levels on the basis of cultural diversity. Narrative analysis of semi-structured interviews with employees of a large research and development organization revealed three types of muted narratives used to respond to mistreatment (muted-but-engaged, angrily disengaged, and resigned) as well as one type of privileged response. The narratives provided evidence of two processes by which voices became muted: repeated silencing over time and silencing through ambiguity of policies.  相似文献

科技信息的开放获取已成为影响学术信息交流与科学发展的重大问题,深刻地影响到科技政策、科技支撑环境发展战略和科技信息服务模式。一大批科学家、科研机构和许多国家的科学管理与科研资助机构,都积极地推动科技信息的开放获取。他们或者制定开放获取政策、要求或鼓励科研人员提供科研成果的开放获取,或者支持开放出版期刊,或者建立机构开放存储库、支持本机构科研成果开放获取。通过这一系列的措施,科学界希望能够促进科研成果不受限制地广泛传播和自由获取、以及促进科研成果通过公共机制长期可靠保存和利用,以保障科技知识资产的国家保护和科研机构的知识资产管理。  相似文献
