学前教育中羌文化传承的“生态语境”与“叙事体验”探究     

来嫔  杨达 《康定民族师范高等专科学校学报》2015,24(2)

羌文化是多元文化中的重要一支,却面临着羌语濒危,文化主体、文化传承“生态语境”缺失,文化传承行为严重失衡等现实困境.学前儿童是未来文化主体,教育是人类文化得以传承的主要途径,学前教育是实施民族文化传承教育的关键期和重要期,学前教育中羌文化传承“语境”损毁而导致羌文化传承教育弱化.因此,塑造学前教育羌文化传承的“生态语境”,突围羌文化传承困境,实施学前儿童羌文化传承“叙事体验”教育,是学前教育羌文化传承的有效建设和重要驱动.  相似文献   

Examining the Rule of Thumb of Not Using Multilevel Modeling: The “Design Effect Smaller Than Two” Rule     

Mark H. C. Lai  Oi-man Kwok 《Journal of Experimental Education》2015,83(3):423-438

Educational researchers commonly use the rule of thumb of “design effect smaller than 2” as the justification of not accounting for the multilevel or clustered structure in their data. The rule, however, has not yet been systematically studied in previous research. In the present study, we generated data from three different models (which differ in the location of the clustering effect). With a 3 (design effect) × 5 (cluster size) × 4 (number of clusters) Monte Carlo simulation study we found that the rule should not be applied when researchers: (a) are interested in the effects of higher-level predictors, or (b) have a cluster size less than 10. Implications of the findings and limitations of the study are discussed.  相似文献

Disambiguation and co-authorship networks of the U.S. patent inventor database (1975–2010)     

Guan-Cheng Li  Ronald Lai  Alexander D’Amour  David M. Doolin  Ye Sun  Vetle I. Torvik  Amy Z. Yu  Lee Fleming 《Research Policy》2014

Research into invention, innovation policy, and technology strategy can greatly benefit from an accurate understanding of inventor careers. The United States Patent and Trademark Office does not provide unique inventor identifiers, however, making large-scale studies challenging. Many scholars of innovation have implemented ad-hoc disambiguation methods based on string similarity thresholds and string comparison matching; such methods have been shown to be vulnerable to a number of problems that can adversely affect research results. The authors address this issue contributing (1) an application of the Author-ity disambiguation approach (0170 and 0175) to the US utility patent database, (2) a new iterative blocking scheme that expands the match space of this algorithm while maintaining scalability, (3) a public posting of the algorithm and code, and (4) a public posting of the results of the algorithm in the form of a database of inventors and their associated patents. The paper provides an overview of the disambiguation method, assesses its accuracy, and calculates network measures based on co-authorship and collaboration variables. It illustrates the potential for large-scale innovation studies across time and space with visualizations of inventor mobility across the United States. The complete input and results data from the original disambiguation are available at (http://dvn.iq.harvard.edu/dvn/dv/patent); revised data described here are at (http://funglab.berkeley.edu/pub/disamb_no_postpolishing.csv); original and revised code is available at (https://github.com/funginstitute/disambiguator); visualizations of inventor mobility are at (http://funglab.berkeley.edu/mobility/).  相似文献
