理想第二类超导体的临界场

借助Ｇｉｎｚｂｕｒｇ－Ｌａｕｄａｕ理论，阐述了理想第二类超导体处于混合态的临界场，并得出下临界场Ｈｃ１与穿透深度λ、相干长度ξ有关，上临界场Ｈｃ２与参量α有关的结论。     

竞走运动员“阈值速度”的研究

为不断提高竞走运动员的训练水平,通过对运动员血液中乳酸含量的分析,求出其运动强度达乳酸阈时的速度(即“阈值速度”),对提高竞走运动员有氧代谢能力的训练有重要意义。研究发现运动员血乳酸浓度总体位置达3mmol/L 左右时,出现非线性临界点。达临界点时的“阈值速度”与运动成绩、比赛速度呈高度相关;临界点时的平均心率为162次/分。本文采用坐标作图方法求得乳酸阈值及“阈值速度”。     

An Australian Proposal for Doing Critical Literacy Assessment: The Case of Writing

In this article we present current thinking and practices in Queens land, Australia, about how to do critical literacy assessment in the English classroom. In taking this focus, we propose and discuss a framework that brings together interest in text analysis and social practices. Then, we apply the framework showing how it can be used to generate writing tasks and assessment criteria that are consistent with critical pedagogy. Finally, the challenges of moving to a socially critical, discourse‐oriented approach to assessment are considered.     

二语习得的关键期假说及对外语教学的启示

本文回顾了20世纪60年代以来对二语习得关键期的研究,从赞成派和反对派两方面为此理论提供依据,并指出第三种可能:二语习得可能存在多重关键期,即存在多个关键期在不同时期影响语言习得的不同方面。指出成人外语教学应实施不同的教学策略,利用成人外语学习的优势采用相应的教学方法,以达到最佳的学习效果。     

Sports-based Text Sets: Fostering Critical Literacy at the Intersections of Sport and Society

Sports culture is central to the lives of many students, whether they participate in athletic competitions or sports fandom. Unfortunately, sports culture also reflects many sociopolitical issues and inequities that impinge upon our greater society in the present day (e.g., domestic violence, racism). For those reasons, sports-based text sets—diverse collections of texts about figures, events, and happenings in sports culture—stand to support teachers in honoring students' knowledge of and interests in sports culture while also facilitating critical literacy practices through the investigation of inequities that ail both sport and society. This article introduces the notion of a sports-based text set, addresses the types of texts that might be featured in such a set, and presents ideas for exploring specific texts with students, using the issue of inequitable compensation for male and female athletes as an example.     

‘We are more than EFL teachers – we are educators’: emancipating EFL student-teachers through photovoice

The prevailing pedagogical orientations of English as a foreign language (EFL) education in Spain oppress learners intellectually in ways that are counterproductive to their learning. As a reaction to this, 129 EFL student-teachers (STs) took part during the 2013/14, 2014/15, and 2015/16 academic years in a workshop which drew on the methodology of participatory action research and on photovoice as a data-creating strategy, in order to emancipate these STs intellectually, boost their EFL development, and offer an alternative critical model for their future EFL teaching. The research was assessed collectively through a variety of qualitative strategies. Results showed that the photovoice workshop created a rich and meaningful context for EFL learning, one which enabled the STs to fully actualize their intellectual potential by producing knowledge collectively, thereby setting a memorable educational example for their own future teaching.     

Introducing veteran critical theory

Research on student veterans is in an infant state. As veterans continue to enroll in institutions of higher education, researchers must explore new ways of knowing student veterans. It is not enough to only describe and model this growing demographic, researchers must also have a tool for criticism and question. The next in an important tradition of emancipatory paradigms, this article suggests a critical theory built on current critical conversations but adapted for the unique characteristics of the student veteran. The article defines the need for a critical theory (Veteran Critical Theory), explains 11 tenets for this new theory, and discusses how these tenets could be used by administrators, faculty, student affairs professionals, and students in the higher education community.     

技术批判理论视域下《美国国家教育技术计划》文本分析

技术的不断进步对教育领域相关政策的制定起着越来越重要的作用.《美国国家教育技术计划》是提高技术在教育中应用的纲领性文件.从技术批判理论的视角出发,通过文本分析的研究方法,揭示出技术影响下蕴含在教育领域中一种追求效率的技术理性思维,具体表现为基于数据分析的真理判定、基于技术系统的社会秩序、基于技术素养的教育目的.文章借鉴技术批判理论的观点,试图探求解决当下教育政策文本中过于追求技术理性的问题,实现理性与艺术的结合.据此,对我国教育技术政策制定提供一定的启示,包括关注时代合理性诉求,反思人文不合理问题,权衡技术与人的关系.
