我国师范教育的历史省思——20世纪前半叶中国师范教育发展研究

中国师范教育在其110年的发展过程中,既有成功的经验,也有失败的教训。110年来师范教育发展的教训有:未能形成中国特色的师范教育理论,导致师范教育行而不远;速成师范过多,影响师范教育长远发展;对基础教育研究过少,导致毕业生无法适应教学;管理制度弹性过大,导致制度形同虚设。

Maintaining the anonymity of cadavers in medical education: Historic relic or educational and ethical necessity?

Throughout the modern history of anatomical dissection by medical and other health science students, cadavers have been anonymized. This has meant that students have been provided with limited, if any, information on the identities or medical histories of those they are dissecting. While there was little way around this when the bodies were unclaimed, this need not be the case when the bodies have been donated. However, with a few exceptions, no efforts have been made to change this model. Recent attempts to move anatomy teaching in a more humanistic direction, by emphasizing the cadaver as the students' first patient and with the growth of commemoration services following the dissecting process, raise the question of whether cadavers should continue to be anonymized. In laying a basis for discussion of this matter, we outline what appear to be the virtues of anonymity, and the form that alternatives to anonymity might take. The options identified are nonidentification, low information; nonidentification, moderate information; and identification, full information. The virtues and drawbacks of each of these possibilities are assessed by analyzing their value for students, and also for donors and their families. Policy issues raised by alternatives are also considered. This article provides a basis for continued discussion and suggestions for further research in this area.

Using Formative & Summative Assessment to Evaluate Library Instruction in an Online First Year Writing Course

Ensuring quality library instruction in an online-exclusive First Year Writing (FYW) course is important and challenging. Assessing what the students learned and how is equally important. The authors collaborate and co-teach the information literacy portion of an online-exclusive second semester FYW course at the University of Tennessee at Chattanooga. To teach information literacy skills, the authors developed tutorial videos, worksheets, and a Librarian AMA (Ask Me Anything) discussion forum for the students. The authors completed formative and summative assessments to measure the efficacy of the activities. This article explores their assessment, findings, and recommendations.     

The role of occupational identity in negotiating traumatic experiences: the case of a rural fire department

Firefighters are routinely exposed to situations involving contact with deceased or injured children, burned and seriously injured bodies, and high-uncertainty calls. Thus, many firefighters suffer debilitating consequences including depression, dysfunctional drinking, and posttraumatic stress disorder. Using an identity tensions framework, we sought to understand the challenges firefighters encounter as they cope with exposure to traumatic events. We interviewed 27 members of a rural fire department and used a constant comparative method to analyze their responses. We found trauma was induced when occupational identity intersected futile situations and those involving children; tensions emerged between traditional and newer, emergent firefighting cultures; and firefighters experience tensions in negotiating how and when to express emotion. Based on these findings, we offer a number of practical implications centering on an occupational identity tensions framework to encourage reflexivity in firefighters and moving beyond older, enduring stereotypes of what it means to be a firefighter.
