Managing physical education lessons: an interactional approach

Physical education (PE) lessons involve complex and dynamic interactive sequences between students, equipment and teacher. The potential for unexpected and/or unintended events is relatively large, a point reflected in an increasing amount of scholarship dealing with classroom management (CM). This scholarship further suggests that unexpected and disruptive events negatively impact on learning and can have deleterious effects on teacher health. Despite considerable potential for these kinds of events, many PE lessons occur in structured, organized ways. The broad purpose of this paper is to consider how classroom action becomes ordered in PE contexts. To this end, an interactional approach is put forward including the specific analytic concepts of directives, epistemic authority and deontic authority. To exemplify the approach, the micro-dynamics of a situation in which a group of students are building a human pyramid is examined. The examination draws attention to: how the teacher engages in a series of interactions with the students to move the sequence forward; how the students themselves achieve order through their interactions with one another; and how the characteristics of the activity help to organize the students' behaviors and limit possibilities for action. The discussion is located against a backdrop of current CM scholarship. Reference is also made to two aspects of social context: the increasing prominence of managerial discourse in educational arenas and the significance of student-centeredness in pedagogical theory. Both aspects appear to influence how order can be achieved in PE today. The analysis raises issues related to pedagogy, management and authority which are addressed in the final two sections of the paper.     

Setting the Stage and Keeping Sane: Implementing ArchivesSpace at the University of Minnesota

As the University of Minnesota's Archives and Special Collections began the daunting task of migrating into ArchivesSpace over 5,000 finding aids from fifteen different units, a clearly defined workflow provided clarity and success. This article outlines how staff developed an implementation timeline and workflow, harnessed support from partners in IT, provided training, and what the benchmarks to success were. By sharing this well-documented and thought-out implementation workflow, it can provide guidance as others try to navigate the many moving parts of implementing new collection management technology.     

Maximum Product,Even Less Process: Increasing Efficiencies in Archival Processing Using ArchivesSpace

As the archival profession has adapted to new challenges and adopted modern practices like More Product, Less Process, the University of Minnesota has embraced these changes. Even so, implementing new practices can take time and effort. With the adoption of ArchivesSpace in 2016, the University found itself being fast-tracked to even more efficient methods for establishing physical and intellectual control over collections. This article will examine the case studies of two large collections that were in the midst of being processed when ArchivesSpace was implemented at the University of Minnesota. How did the switch to ArchivesSpace impact the processing of these collections, and how will these experiences impact the future of archival processing at the University?     

The Florida Geographic Data Library: Lessons Learned and Workflows for Geospatial Data Management

The University of Florida GeoPlan Center has been organizing, standardizing, and distributing geospatial data since 1998 through the Florida Geographic Data Library (FGDL), a collection of Florida geospatial data from various agencies, as well as data developed in-house. With funding from the Florida Department of Transportation (FDOT), FGDL serves as a public distribution mechanism for hundreds of Florida geospatial data layers. Since 2004, FGDL layers have formed the data foundation for FDOT's interagency application known as efficient transportation decision making (ETDM), which facilitates the review and permitting process for proposed transportation projects. Data layers are standardized and inspected to ensure that the data are adequate for use in analysis and decision making. To efficiently manage the geospatial data and workflows, a quality assurance/quality control (QAQC) process and relational database schema was developed to track the standardization procedures, lineage, versioning, and archiving of the data layers. This article details the history of the Florida Geographic Data Library, challenges of managing a large geospatial data repository, development of a QAQC process and database schema, and lessons learned.

高校招生中“加分降线投档”政策之分析

“享受加分考生名单、录取结果要公示”,是高校招生要实现公开、公平与公正政策的表现之一。从公共政策和理性的视角审视,“加分降线投档”政策是政府为了解决招生过程中出现的特殊群体问题而制定的具体政策,具有公共政策的特质,对教育行动具有导向作用；该政策也是人们充分运用理性的结果,既能体现工具理性,也虑及价值平衡问题,给价值理性留有一定空间。     

工业化中期阶段的城乡收入差距平抑机制的建构

城乡居民收入存在差距,是世界各国工业化进程中普遍存在的基本事实,但城乡居民收入差距的过分扩大,会导致一系列不利于经济发展的后果,必须努力寻求城乡收入差距的平抑机制。我国当前城乡收入差距的平抑机制包括:调整国民收入分配格局,加大财政对农业、农村、农民的支持力度;进行制度创新,为平抑城乡收入差距提供制度保障;推进工业化、城镇化进程,转移农村富余劳动力;积极推进农业产业化经营,拓展农业内部增收渠道。

Reflectors as online extraverts?

Increasingly, online learning is perceived as an effective method of instruction. Much recent educational research has focused on examining the purposes and situations for which online education is best suited. In this paper, students enrolled in two online courses are compared with their peers enrolled in equivalent classroom‐based courses to investigate aspects of the relationship between learning style and mode of delivery. Student satisfaction measures are taken from participants in both modes of delivery and compared with student learning style. Feedback from the ‘Reflector’ learning style demonstrates higher satisfaction levels with the online mode of delivery compared with their matched counterparts following equivalent classroom‐based courses. Therefore, whilst ‘Reflectors’ might be regarded as Introverts in the traditional classroom setting, the additional time for reflection offered by online delivery makes this group more likely to contribute to online discussion, report higher satisfaction levels and generally behave more like online Extraverts.
