小学语文教学的人文精神     

杨冰  李如 《重庆第二师范学院学报》2011,24(5):166-169

人文精神的缺失是我国基础教育存在的严重弊端。本文列举了小学语文教学人文教育缺失状况,提出在小学语文教学中进行人文精神的渗透,必须立足课堂、拓展课外;植根教材、走向生活;重视朗读、紧扣情感;尊重个性、注重体验。  相似文献   

从同质公平到差异公平——美国基础教育财政政策中公平理念的转变、应用与启示     

付建军 《广东广播电视大学学报》2011,20(4):88-92

20世纪90年代后期,美国基础教育财政体制实现了从“公平性财政”向“充足性财政”的转变。从“公平性财政”到“充足性财政”凸显了内涵于美国基础教育财政政策中公平理念从同质向差异的转化,这种从同质公平向差异公平的理念转化具体表现为美国基础教育财政政策中“充足性财政政策”的产生和运用。“充足性财政政策”降低了美国基础教育中的财政分配不公平程度,为中国的义务教育财政改革提供了借鉴可能。  相似文献   

基础教育阶段英语教师的课堂结课艺术     

夏莲茹 《南阳师范学院学报》2011,10(7):103-105

作为课堂教学的最后一个环节,结课艺术对语言教师的课堂教学效果起着画龙点睛的作用。好的结课是巩固课堂教学内容、保证教学效果和开发学生智力的良机。本文论述了结课艺术在英语课堂教学中的作用,探讨了归纳总结、竞赛、激励、首尾呼应等艺术性的结课方法,从而给广大语言教师提供了有用的教学启示。  相似文献

NiCo_2O_4纳米结构阵列的水热合成与氧析出特性研究     

陈传胜  张作胜  陈伟杰  乔浏 《安徽职业技术学院学报》2020,(1):16-19,41

钴酸镍纳米材料具有良好的电催化氧析出反应(Oxygen Evolution Reaction,OER)活性,是一种很有发展潜力的非贵金属电催化材料。文章以碳纤维纸为基底,采用水热合成的方法对纳米结构钴酸镍的生长进行了系统的研究,分别考察了生长温度、前驱体浓度和配比、生长时间对产物的形貌、尺寸、物相结构、OER电化学性能的影响,通过对比分析后发现在生长温度100℃、生长时间5h、镍钴比为2:1时所获得的多孔片状钴酸镍纳米结构具有最佳的OER特性。  相似文献   

Evaluation of adverse drug reaction formatting in drug information mobile phone applications     

Sean M. McConachie  Dena Berri  Jewel Konja  Christopher A. Giuliano 《Journal of the Medical Library Association》2022,110(1):81

Objective:To evaluate the differences in presentation (formatting) of adverse drug reaction (ADR) information within drug monographs in commonly used drug information (DI) mobile device applications.Methods:A cross-sectional analysis of ADR formatting of twenty commonly prescribed oral medications within seven DI mobile applications was performed. Databases were assessed for ADR information, including presence of placebo comparisons, severity of ADR, onset of ADR, formatting of ADRs in percentile (quantitative) format or qualitative format, whether references were used to cite information, and whether ADRs are grouped by organ system. Data was collected by two study investigators and discrepancies were resolved via consensus.Results:The seven DI mobile applications varied significantly on every analyzed ADR variable with the exception of ADR onset, which was absent in all databases. Significant differences were found for variables known to impact clinical judgment such as placebo comparisons and qualitative versus quantitative formatting. Placebo comparisons were most common among monographs in Lexicomp (30%) but were absent among monographs within other applications. Quantitative information was commonly used in most databases but was absent in Epocrates. Qualitative formatting was present in all Epocrates and Micromedex applications but absent in the majority of other applications. Substantial variations were also found in severity and grouping information.Conclusion:Substantial variation in ADR formatting exists among the most common DI mobile applications. These differences may translate into alternative interpretations of medical information and thus impact clinical judgment. Health care librarians and clinicians should consider ADR formatting when choosing between DI applications.  相似文献   

Facilitators and Barriers to Movement Integration in Elementary Classrooms: A Systematic Review     

Robert Dan Michael  Cate A. Egan  Lynda Nilges  Ali Brian  Robert Johnson 《Research quarterly for exercise and sport》2019,90(2):151-162

Purpose: A systematic review was conducted to identify facilitators and barriers to movement integration (MI) in elementary school classrooms. Method: Online databases (Educational Resources Information Center, Google Scholar, PsycINFO, and PubMed) served as data sources for the study. Following the PRISMA guidelines, relevant published research on MI was identified and screened for inclusion in a qualitative synthesis. Content analysis of the included articles (N = 28) was used to identify themes of MI facilitators and barriers. Facilitators and barriers were then categorized using a social-ecological framework. Results: A total of 12 themes of MI facilitators and barriers were identified and categorized into two social-ecological levels: institutional factors (e.g., administrative support, resources) and intrapersonal factors (e.g., teacher confidence, ease of implementation). Conclusion: This review can inform research and practice aimed at supporting the implementation of MI in elementary classrooms.  相似文献
