中文学术图书的Altmetrics数据生成动机及数据可用性探析——以豆瓣读书平台“短评”为例     

魏佳文  韩毅 《图书情报工作》2021,65(2):98-106

[目的/意义] 探讨用户在“豆瓣读书”发布短评的动机,尝试判断短评作为图书影响力的评估指标是否有效,以期为中文学术图书评价的Altmetrics指标建构提供参考。[方法/过程] 以CBKCI统计报告公布的被引前十的古籍类中文学术图书为样本,采用扎根理论对样本图书在“豆瓣读书”网的1 142条“短评”进行分析,探究短评的产生动机及相应短评数据的可用性。[结果/结论] 用户产生短评的动机包括讨论、分享、消遣娱乐、外界压力、情感宣泄和资料获取6个主范畴。其中,“讨论”动机是最主要的动机,其两个子动机“表达与图书有关的个人经验或想法”和“表达对图书的见解或个人解释”占所有短评数据的四成以上,表明用户不是仅复制图书部分句子或章节,而是试图找到并传播图书最有价值的部分,此类短评数据可用以评价中文学术图书价值;而“分享” “消遣娱乐” “外界压力” “情感宣泄”和“资料获取”等动机相对来说难以较好地反映用户对图书的态度和认知,不宜纳入中文学术图书Altmetrics评价指标中。  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

Preanalytical phase--a continuous challenge for laboratory professionals     

Simundic AM  Lippi G 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2012,22(2):145-149

Preanalytical phase is the most vulnerable part of the total testing process and is considered to be among the greatest challenges to the laboratory professionals. However, preanalytical activities, management of unsuitable specimens and reporting policies are not fully standardized, nor harmonized worldwide. Several standards related to blood sampling and sample transportation and handling are available, but compliance to those guidelines is low, especially outside the laboratory and if blood sampling is done without the direct supervision of the laboratory staff. Furthermore, for some most critical procedures within the preanalytical phase, internationally accepted guidelines and recommendations as well as related quality measures are unfortunately unavailable. There is large heterogeneity in the criteria for sample rejection, the different strategies by which unacceptable samples are managed, processed and test results reported worldwide. Management of unacceptable specimens warrants therefore immediate harmonization. Alongside the challenging and long road of patient safety, preanalytical phase offers room for improvement, and Editors at Biochemia Medica Journal definitely hope to continue providing a respective mean for reporting studies on different preanalytical phase topics. With pleasure and delight we invite potential future authors to submit their articles examining the quality of various preanalytical activities to Biochemia Medica. We will keep nurturing this topic as our prominent feature and by this we hope to be able to deliver valid evidence for some future guidelines and recommendations.  相似文献
