Examining Physics Graduate Teaching Assistants’ Pedagogical Content Knowledge for Teaching a New Physics Curriculum

In this study, we investigated the pedagogical content knowledge (PCK) that physics graduate teaching assistants (TAs) developed in the context of teaching a new introductory physics curriculum, Matter and Interactions (M&I). M&I is an innovative introductory physics course that emphasizes a unified framework for understanding the world and presents physics through a few fundamental principles rather than exposing students to concepts through a series of derived equations. Through a qualitative, multiple case study research design, data were collected from multiple sources: non-participant observations, digitally recorded video, semi-structured interviews, TAs?? written reflections, and researchers?? field notes. The TAs?? PCK included three components: (a) knowledge of M&I curriculum goals, (b) knowledge of instructional strategies appropriate to the M&I course, and (c) knowledge of students?? learning. This study shows the complexity of adopting curriculum reforms and the necessity to support the faculty??s and TAs?? knowledge development when a novel science curriculum is adopted.     

Teachers’ sources of knowledge for field trip practices

Teachers draw from many personal and professional experiences when organising and leading field trips. In order to identify the influences on teachers?? field trip practices, I used surveys, interviews, artifacts and observations gathered from teachers who led trips to an aquarium. Findings clarified the types of influence and the impact that these influences had on practice. For example, teachers adapted knowledge acquired for use in their field trips from four types of training (1) informal mentoring, (2) past experience on various trips, (3) various outdoor education training and (4) traditional classroom education training. A focus was the nature of each of these training types and how teachers acquire and adapt their knowledge. Previous research has shown that, while a variety of cognitive and affective outcomes often results from field trips, there is also a pattern of underutilised resources and missed learning opportunities during trips. This study offers insight regarding strengths and weaknesses of teachers?? preparation for leading field trips by documenting how and what skills are learned and applied. Therefore the findings presented here are suggestive of ways in which efforts to formally support and enhance teachers?? trip-leading skills by means of professional development might build on teachers?? existing sources of knowledge.     

工作场所学习与绩效:整合教学、研究与咨询的实践领域——访罗纳德·雅各布斯教授

在终身学习理念的影响下,工作场所自然成为学习的重要空间。一般而言,工作场所学习的时间比学校学习的时间还要漫长,因此,对工作场所学习这一研究领域的重要性怎么强调也不为过。个体可以通过工作场所学习实现自我价值、促进其生涯的发展;组织可以通过工作场所学习提升整体的竞争力和实现其持续性发展;当社会的经济和结构处于转型阶段,工作场所学习更成为促进个体和组织适应环境变化和主动创新的重要措施。借在美国学习的机会,笔者访谈了人力资源开发领域的著名学者雅各布斯(Ronald L.Jacobs)博士,他在访谈中论述了多个与人力资源开发专业相关的问题,并认为工作场所学习与绩效咨询是人力资源开发重要的实践领域,他整合了在该领域的教学经验、研究主题和咨询项目,实现了三者的互动和连通,多维度地促进该领域的发展。雅各布斯博士,美国伊利诺伊大学厄巴纳-香槟分校(University of Illinois at Urbana-Champaign,简称UIUC)人力资源开发专业教授,另外还担任该校教育学院国际事务处主任一职,他在各类期刊发表了百余篇论文,出版了六本人力资源开发方面的书籍。1994年,雅各布斯博士获得了由美国培训与开发协会(ASTD)颁发的教学科技研究奖;1995年,人力资源开发学会(AHRD)表彰了他在学术上对人力资源开发领域的卓越贡献。从1998年到2001年,他担任《人力资源开发季刊》(Human Resource Development Quarterly)(SSCI来源期刊,且为人力资源开发领域的主要学术期刊)的主编,现在仍担任该杂志的客座编辑。雅各布斯博士还担任ASTD工作场所学习与绩效(Workplace Learning and Performance)认证机构的顾问委员,并于2012年当选为新一届人力资源开发学会主席。雅各布斯博士早在1987年就提出"结构化在职培训"这一概念,并著有《员工岗位培训手册》(StructuredOn-the-Job Training),该书成为很多人力资源开发实践者和培训师的参考书,且被翻译为简体中文、繁体中文、韩文与阿拉伯文等多种语言,他早期的研究着重于研究结构化在职培训的经济效益,协助组织做出与培训相关的决定。目前,韩国就业及劳动部已在全国范围内实施大规模"结构化在职培训"试行计划,以帮助本国中小型企业提高竞争力。雅各布斯博士在人力资源开发领域整合了系统理论、工作场所学习、绩效咨询等理念,并在ISO10015培训质量标准中完善了绩效分析与投资报酬率等概念。雅各布斯博士曾受邀至荷兰乌特列支大学、台湾师范大学、新加坡南洋理工大学、华东师范大学等高校担任客座教授或特聘教授。他有三十多位博士学生现供职于全球各大学人力资源开发及相关领域的教授。雅各布斯博士多年来积极参与对实践的指导工作,他为许多企业组织与政府机构提供过咨询,包括通用汽车、荷兰航空公司、雅培、现代汽车、希捷、莫顿盐业、科威特国家石油公司、沙特阿拉伯国家石油公司等。雅各布斯博士参与的咨询项目通过开发工作场所绩效系统来满足对员工的能力需求,擅长采用合作研究整合其咨询活动、学术研究和教学为一体。雅各布斯博士喜欢航海、高尔夫,以及他在伊利湖畔别墅的夏日时光。     

Library as the Technology Hub for the Health Sciences

Abstract

Academic health sciences libraries have an important role in facilitating the use of technology in health sciences curricula. Serving as a technology hub, the library supports, advocates, and provides access to new technologies. The library introduces many faculty and students to new technology tools, techniques, and equipment for new multimedia creation. As the technology hub grows and expands, library personnel can provide expertise, which demonstrates the library's value in leading the exploration of new technology, including Do-It-Yourself multimedia tools, virtual reality, virtual anatomy, and 3D printing.     

Managing Dualities in Planned Change Initiatives

Dualities play an important role in creating the conditions for change and managing planned change initiatives. Building on Seo, Putnam, and Bartunek's (2003) work, this study focuses on the dualities associated with managing change processes. A case study of a planned change process called the Circle of Prosperity Initiative, a multi-stakeholder dialogue designed to bring information technology to Indian country, was analyzed. Three dualities emerged regarding the structuring and management of the change initiative: (1) inclusion–exclusion, (2) preservation–change, and (3) centrality–parity. The findings suggested that these dualities were managed using Seo et al.'s (2003) strategy of connection. Notably, the strategy of connection relied heavily on the ability of change agents to set context within and between the different phases of the initiative and involved three specific practices for setting context setting: (1) commonplacing, (2) bounded mutuality, and (3) reflexive positioning.     

Graduate Teaching Assistants’ Knowledge Development for Teaching a Novel Physics Curriculum

Matter and Interactions (M&I) has recently been adopted as a novel introductory physics course that focuses on the application of a small number of fundamental physical principles to the atomic and molecular nature of matter. This study investigated how five physics teaching assistants (TAs) developed professional knowledge for teaching from their teaching experiences. Specifically, we explored what experiences influenced their knowledge development for teaching the innovative introductory physics course, M&I. Through a qualitative, multiple case study research design, data was collected from multiple sources: non-participant observations, digitally recorded video, semistructured interviews, TAs’ written reflections, and researchers’ field notes. As TA’s progressed through the semester, two experiences emerged as having a significant role in their development of knowledge for teaching M&I: (1) setting teaching, learning, and curriculum goals for their classes; and (2) encountering dilemmas of teaching and learning. The results of this study will contribute to future preparation of the innovative introductory physics course as well as other college level science courses.     

TRAGEDY AND THE MEANING OF SCHOOL SHOOTINGS

School shootings are traumatic events that cause a community to question itself, its values, and its educational systems. In this article Bryan Warnick, Benjamin Johnson, and Samuel Rocha explore the meanings of school shootings by examining three recent books on school violence. Topics that grow out of these books include (1) how school shootings might be seen as ceremonial rituals, (2) how schools come to be seen as appropriate places for shootings, and (3) how advice to educators relating to school shootings might change the practice of teaching. The authors present various ways of understanding school shootings that may eventually prove helpful, but they also highlight the problems, tensions, and contradictions associated with each position. In the end, the authors argue, the circumstances surrounding school shootings demonstrate the need for the “tragic sense” in education. This need for the tragic sense, while manifest in many different areas of schooling, is exemplified most clearly in targeted school shootings.     

Homesickness as a construct of the migrant experience

This paper is an exploration of the concept of homesickness and the migrant's relation to the idea of home. It draws on the writer's personal experience of Caribbean migration—discussing different phases and facets in the evolution of the construct that includes notions of essence and hybridity. It suggests how a return to ‘home’ and roots can broaden the understanding of what it means to inhabit the modern world—and also help in the continuous process of reconstructing identity.
