ABSTRACTFace, understood as public image, exerts critical influence on interpersonal communication. Incorporating insight from cultural neuroscience, a number of potential mismatches with regard to facework are revealed when methodologies originated from the West are applied in a different context. This paper examines culturally appropriate face strategies in cooperative learning among Vietnamese learners. Our results show that discussion outcomes increase when self-face and other-face are confirmed and group-face is mildly confronted in form of intergroup competition. The paper indicates that educational methods underpinned by fundamental psychological assumptions based on Western values should be adjusted to be culturally appropriate for contexts in which it is applied. 相似文献

This case study explores how a group of Grade 9 students engaged in sociopolitical discourses and actions in a science class in a mostly indigenous student school in Nepal. The study used sociopolitical consciousness (SPC) as a framework to document and understand indigenous students’ SPC-oriented science interactions and subsequent social change actions. We used ethnographic methods of data collection over 6 months. The study focused on the actions of 4 girls and 2 boys belonging to the indigenous Tharu group. Data were analyzed using iterative qualitative methods. The study findings show that students are capable of engaging in critical thinking, critical reflecting, and taking actions for social change. Additionally, students are competent to link their experiences with social, structural, and political discrimination to the relevant science content they learn. The study presents four thematic findings related to SPC and science teaching and learning: Fostering social justice awareness in science class, fostering structural understanding of inequities in sickle cell disease, fostering sociopolitical actions for sickle cell disease, and the teacher's activist pedagogy for SPC in science learning. Implications of the study are that culturally relevant pedagogy helps indigenous students to become sociopolitically more aware of the links between science and social change. Adding aspects of critical pedagogies in science teaching could encourage students to become more sociopolitically reflective about science learning. 相似文献

数学教师知识的合理建构是培养高素质数学教师队伍的关键因素之一,而职前阶段是数学教师知识建构的起始阶段。在我国基础教育数学课程改革向纵深发展的时候,关于职前阶段数学教师知识的模型和合理建构的基本途径问题仍值得我们探讨和思考。 相似文献

近几年来,各高校图书馆都纷纷建设统一检索平台,比如上海交通大学的"思源探索",北京大学的"未名学术搜索"等,都试图通过统一检索平台给读者带来知识服务。但这些检索平台还未能解决输入关键词的语义联想以及检索平台的元数据更新问题,这也会产生很多实际问题。为了解决这些问题,就必须要在统一检索平台中引入语义网的相关技术,从而在细节上完善统一检索平台,真正为读者提供一站式的检索平台。 相似文献

Employing metasynthesis as a method, this study examined 52 empirical articles on culturally relevant and responsive science education in K‐12 settings to determine the nature and scope of complementarity between culturally responsive and inquiry‐based science practices (i.e., science and engineering practices identified in the National Research Council's Framework for K‐12 Science Education). The findings from this study indicate several areas of complementarity. Most often, the inquiry‐based practices Obtaining, Evaluating, and Communicating Information, Constructing Explanations and Designing Solutions, and Developing and Using Models were used to advance culturally responsive instruction and assessment. The use and development of models, in particular, allowed students to explore scientific concepts through families’ funds of knowledge and explain content from Western science and Indigenous Knowledge perspectives. Moreover, students frequently Analyzed and Interpreted Data when interrogating science content in sociopolitical consciousness‐raising experiences, such as identifying pollution and asthma incidences in an urban area according to neighborhood location. Specific inquiry‐based practices were underutilized when advancing culturally responsive science instruction, though. For example, Using Mathematics and Computational Thinking and Engaging in Argument from Evidence were infrequently encountered. However, culturally responsive engineering‐related practices were most often connected with these, and thus, represent potential areas for future complementarity, particularly as the United States embraces the Next Generation Science Standards. In considering innovative directions for advancing equitable science education, several possibilities are discussed in light of the findings of this study.© 2017 Wiley Periodicals, Inc.

ABSTRACT. Institutional repositories (IRs) provide storage and access to digitally produced scholarship. In order to improve storage and access to these materials, it is important for the creators to describe the contents adequately. Following generally accepted best practices in terms of file formats is encouraged, as is providing basic metadata about the content of the items. Some of the benefits of utilizing IRs include the provision of unique identifiers for digital projects and files, institutional commitment to preserving the files, and increased access through metadata protocols. Collaboration between creators and librarians is encouraged to ensure that standards are followed when appropriate, and that metadata is of the highest quality to ensure good preservation and access to the content. 相似文献

规模经济理论被应用于大学适度规模研究,是基于大学资源优化配置后能产生规模效益的认识,已经采用的研究方法主要有：统计成本分析法、适生存检验法和MR与MC分析法。规模经济理论及研究方法的局限性及高等教育的特殊性,使得大学最小有效规模或最佳规模的研究结果有很大差异。因此,大学在选择适度规模时应综合考虑基本办学条件、学校发展定位、教育市场需求等约束条件,根据自身资源利用与再生潜力确立一个相对合理的规模区间。 相似文献
