Measuring scientific contributions with modified fractional counting     

Gunnar Sivertsen  Ronald Rousseau  Lin Zhang 《Journal of Informetrics》2019,13(2):679-694

We develop and propose a new counting method at the aggregate level for contributions to scientific publications called modified fractional counting (MFC). We show that, compared to traditional complete-normalized fractional counting, it eliminates the extreme differences in contributions over time that otherwise occur between scientists that mainly publish alone or in small groups and those that publish with large groups of co-authors. As an extra benefit we find that scientists in different areas of research turn out to have comparable average contributions to scientific articles. We test the method on scientists at Norway’s largest universities and find that, at an aggregate level, it indeed supports comparability across different co-authorship practices as well as between areas of research. MFC is thereby useful whenever the research output from institutions with different research profiles are compared, as e.g., in the Leiden Ranking. Finally, as MFC is actually a family of indicators, depending on a sensitivity parameter, it can be adapted to the circumstances.  相似文献

学者学术影响力评价指标的优选与学术行为特点的国内外比较     

杜建  张玢  李阳  唐小利  许培扬 《图书情报工作》2011,55(10):98-143

以中国医学科学院73位从事临床科研的博士生导师为样本,分析不同学术年龄组在各学术影响力指标上的表现差异,并采用方差分析和相关性分析辅助优选指标。得到的优选指标包括发文量、总被引次数、篇均被引次数、h指数、A指数、g指数和累计影响因子,其中与“平均量”相关的篇均被引次数、A指数更适合于评价中国高水平学者的学术表现;而m熵指数不太适合于评价中国学者的国际影响力;中国科研人员的评价应该注意学术年龄这一因素。  相似文献   

图书馆评估研究综述     

向远媛 《江苏图书馆学报》2011,(1):59-61,16

图书馆评估一直是图书馆界研究的热点问题之一,研究成果主要集中在5个方面：图书馆评估定义的理论探讨、图书馆评估的主体探讨、图书馆评估的客体探讨、图书馆评估指标体系编制、图书馆评估过程与方法。图书馆评估应逐渐转向以用户为中心的思想和价值理念,针对图书馆工作的目标和实质内容,提升评估标准,建立适合我国国情的准确有效和可持续发展的评估体系和评估方法。  相似文献   

基于NCI的“985工程”高校学科的学术影响力评价     

李峰  缪亚军  戚巍 《科学学与科学技术管理》2011,32(10)

采用“标准影响力”（NCI）方法对“985工程”高校的自然科学、生命及医药科学、工程与技术科学三大学科领域进行评价,发现各学科的学术影响力总体水平不高。基于NCI的学科评价结果不仅能衡量学校之间的相对差距,还能衡量相应学科与世界一流学科的差距,同时具有诊断性和战略性的特点。  相似文献

采用过氧化氢作为氧化剂制备聚合硫酸铁,探讨了硫酸用量、过氧化氢用量、反应温度这三个反应条件对产品各项质量指标的影响。结果表明,当硫酸与硫酸亚铁的摩尔比在0.31～0.41之间,过氧化氢与硫酸亚铁的摩尔比为2∶1,反应温度控制在20～35℃之间,制备所得的聚合硫酸铁的各项质量指标均符合国家标准。  相似文献   

A Study of Learning Behavioral Engagement in Live Teaching     

LIU Sizhuo  LI Shuang  HUANG Jiajing 《Frontiers of Education in China》2022,17(1):69

Based on the related theories and research results of learning behavioral engagement, this study constructed an evaluation framework of learning behavioral engagement in live teaching, which included 24 indicators in three dimensions: compliance with norms, learning participation and social participation. A small-class live English learning for younger students on the ClassIn was taken as a case study program. Five younger students attended this English learning course of 16 lessons totaling 950 minutes. The preset indicators were preliminarily examined based on the teaching records and the recorded course data. Then, experts in the field of educational technology were invited to develop the learning behavioral engagement dimensions and indicator weightings by using the Analytic Hierarchy Process, and to determine the evaluation indicator system for the evaluation of learning behavioral engagement. Finally, based on this framework, the characteristics of learning behavioral engagement of the case course were analyzed, and the influences of students’ individual factors, teaching and environmental factors on learning behavioral engagement in live teaching were investigated.  相似文献

Personal learning environments: design and use / Los entornos personales de aprendizaje en la educación superior: del diseño al uso     

César Coll  Anna Engel  Alexandra Saz  Alfonso Bustos 《Cultura y Educación》2014,26(4):775-801

Abstract

This study focuses on the uses that two groups of higher education students make of technological resources offered by an institution to build their own personal learning environments. The main thesis is that these uses depend on the techno-pedagogical design of the teaching and learning process in which the technological resources are framed. In order to explore and illustrate this thesis two instructional sequences have been analysed. Both use the same technological design, the Elgg platform, which allows users to select and organize a set of resources or widgets according to their interests and needs. The results show that in both cases the uses that students make of technology are related to the characteristics and requirements of the particular techno-pedagogical designs. We conclude that the key is not to offer technological resources to the students so they can build their own personal learning environments, but to design activities that attract and induce them to build these personal environments and to guide and support the process of construction.  相似文献
