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.     

新基础教育价值取向与减负

21世纪的教育，是以人为本的教育，是主体性、发展性教育，这也是基础教育所确立的新基础教育价值取向。用以新基础教育价值取向为核心而形成的新的教育质量观、学生观、人才观及评价观来指导教育实践，必将会减轻学生的学习负担。

Exploring anatomy and physiology using iPad applications

This study examined the use of iPads with anatomy applications (apps) in the laboratory sections of the largest undergraduate course at the university, Anatomy and Physiology, serving more than 300 students. The majority of these students were nursing, exercise science/physical education and biology majors. With a student survey (student opinion) and student practicum grades as metrics, this study determined whether the introduction of this novel mobile technology improved student grades and aided the students in learning the course material. The results indicated that students’ grades improved with the introduction of the iPads, and 78% of the students reported that the iPads facilitated their ability to learn the course material. There was a positive association between frequency of app use and standardized mastery of the course material, as students who used the apps more frequently scored higher and indicated that they felt as though they had learned the material more comprehensively. Owning or having an iPad at home did not have a significant effect on the learning of the material. The general consensus by students was that iPad anatomy apps should be used frequently to better develop student understanding of the course material.

用于计算离散分数阶傅立叶变换的MA-CDFRFT算法改进

基于中心类型DFT矩阵特征分解的MA-CDFRFT(Multiangle Centered Discrete Fractional Fourier Transform)算法在计算一组离散分数阶傅立叶变换DFRFT(Discrete Fractional Fourier Transform)时充分利用FFT运算来减小运算量。结合偶数点离散傅立叶变换DFT(Discrete Fourier Transform)运算的对称性原理，通过数学推导将MA-CDFRFT算法中的一维对称性扩展到频率和变换阶数的二维平面上。利用这个二维对称性原理，改进算法将原算法的主要计算量减小了一半左右。仿真测试结果证明了改进算法的正确性。
