This paper presents a literature review of empirical research related to the use and effect of online social annotation (SA) tools in higher education settings. SA technology is an emerging educational technology that has not yet been extensively used and examined in education. As such, the research focusing on this technology is still very limited. The literature review has aimed at presenting a comprehensive list of SA empirical studies not limited to a particular research method or study domain. Out of more than 90 articles that were initially found, only 16 studies met the inclusion criteria. Among the included studies were eight experimental or quasi-experimental studies and eight evaluation/survey studies. The SA empirical research has provided some evidence regarding the potential effectiveness of integrating social annotation tools into learning activities. Findings from the gathered literature were synthesized to provide recommendations for using SA technology in educational settings. 相似文献

We propose answer extraction and ranking strategies for definitional question answering using linguistic features and definition terminology. A passage expansion technique based on simple anaphora resolution is introduced to retrieve more informative sentences, and a phrase extraction method based on syntactic information of the sentences is proposed to generate a more concise answer. In order to rank the phrases, we use several evidences including external definitions and definition terminology. Although external definitions are useful, it is obvious that they cannot cover all the possible targets. The definition terminology score which reflects how the phrase is definition-like is devised to assist the incomplete external definitions. Experimental results show that the proposed answer extraction and ranking method are effective and also show that our proposed system is comparable to state-of-the-art systems. 相似文献

The purpose of this study was to examine the effect of case studies on learning outcomes, attitudes toward instructions, and team shared mental models (SMM) in a team-based learning environment in an undergraduate educational psychology course. Approximately 105 students who participated in this study were randomly assigned to either a case-study method or a knowledge-representation method. Students in the case-study treatment group received a case study after instruction, while students in the knowledge-representation treatment group engaged in an activity that did not involve problem solving. It was hypothesized that students in the case-study group would have higher learning outcomes scores, higher attitudes scores, and greater team SMM than students in the knowledge-representation group. Overall, the case-study method was effective as indicated by generally higher learning outcomes and more positive attitudes for the case-study treatment group as compared to the knowledge-representation group. It might be important to consider the order in which each of the instructional methods is given. 相似文献

This study focused on Corporate Social Responsibility (CSR) within agribusiness – an industry confronted with particularly high expectations from its societal environment. This study examined the effects of transparency signaling and its interaction with the nature of CSR on publics’ evaluation of an agribusiness company with regards to perceived integrity, perceived competence, and company reputation. Our findings showed that high transparency signaling led to higher perceived integrity, but there were no significant effects on perceived competence and company reputation. Moreover, the effects of transparency signaling were moderated by the nature of CSR on company reputation. The study also revealed that perceived integrity influenced the relationship between transparency and company reputation, while perceived competence was not influenced by transparency signaling. Researchers discuss the implications of these findings for communication professionals sharing CSR information, especially for high involvement industries like food and agriculture. 相似文献

This article describes a group of Druze preschool and kindergarten teachers from Northern Israel who participated in an in-service
course in their community. The focus of the training experience was to improve the social climate of the classroom by implementing
a life-world approach. Analysis of their reports shows that the children’s meaningful learning, improved emotional coping
with ordinary hardships, and mutual social support are a product of intervention that involves multiple, interrelated activity
channels: staff collaboration, guided small group discussions, informal discussions, cooperation with parents and community
agents, and free play. Each activity channel is associated with a compatible, dominant, learning modality and a predominant
interpersonal process—free play, for example, is mainly associated with free inquiry and discourse among children, whereas
group activity is also likely to be associated with learning guided by educators. 相似文献
