The mediating role of workplace social support on the relationship between trait emotional intelligence and teacher burnout

This study investigated the mediating effect of workplace social support on the relationship between trait emotional intelligence and teacher burnout among 307 Chinese middle school teachers. Structural equation modelling revealed a satisfactory fit between the data and our theoretical model. Workplace social support partially mediated the relationship between trait emotional intelligence and teacher burnout. Neither gender nor age moderated the relationship between trait emotional intelligence and teacher burnout. Emotional intelligence and workplace social support can protect teachers from teacher burnout. Thus, providing effective emotional intelligence training and creating supportive workplace conditions requires increased attention from education administrators.

Who's Doing What? Findability and Author-Supplied ETD Metadata in the Library Catalog

Kent State University Libraries’ electronic thesis and dissertation (ETD) cataloging process features contributions by authors, by the ETDcat application, and by catalogers. Who is doing what, and how much of it is findable in the library catalog? An empirical analysis is performed featuring simple frequencies within the KentLINK catalog, articulated by the use of a newly devised rubric. The researchers sought the degree to which the ETD authors, the applications, and the catalogers can supply accurate, findable metadata. Further development of combinatory cataloging processes is suggested. The method of examining the data and the rubric are provided as a framework for other metadata analysis.     

Searching for a New Way to Reach Patrons: A Search Engine Optimization Pilot Project at Binghamton University Libraries

ABSTRACT

Search engine use is one of the most popular online activities. According to a recent OCLC report, nearly all students start their electronic research using a search engine instead of the library Web site. Instead of viewing search engines as competition, however, librarians at Binghamton University Libraries decided to employ search engine optimization strategies to make their Web site more visible on the search engine result pages. Although search engine optimization is used frequently by commercial Web sites, few libraries have attempted to optimize their own sites. This article describes Binghamton University's experiences in developing and implementing an optimization pilot project. The research presented in this article has importance for libraries who may be considering an optimization project for their own sites.     

The agencement of taskification: On new forms of reading and writing in BYOD schools

Abstract

The proliferation of digital devices in educational settings has contributed to the decentralization of knowledge from teachers and established textbooks to fluid online personalized resources, and from blackboards as spaces of materialization of this knowledge to personal screens. In this new constellation, school practices such as reading, writing and note-taking take new forms. How are these practices reconfigured when centered around mobile digital devices? In this paper, we investigate routine lesson practices of a Bring Your Own Device (BYOD) school by means of an ethnographic observation. Adopting the term agencement as a heuristic device, we explore what practices are being constituted and how they are always in connection with one another. Moreover, we show that by practicing they produce different forms of action. We argue that in such a hybrid constellation, tasks find a different status beyond isolated and self-contained units for enhancing learning in different lessons. We introduce task-agencement, through which the task always entails a process of taskification that formats BYOD schools. With taskification, we mean that the task-agencement expands the domain in which tasks not only influence the organization and structure of lessons, but equally the very organization of the BYOD school by enacting a particular form of schooling. Finally, we propose a taskified form as a form of BYOD schooling that templates and formats how practices such as reading and writing, contextualization and introduction of the lesson are conducted.
