基层电大教师的专业身份危机   总被引：1，自引：0，他引：1  

陈胜兵  梁德深 《现代远程教育研究》2011,(3):66-71

由于电大运作模式的弊端、教师管理的失范、实践理念的偏差和教师专业发展的滞后造成了基层电大教师身份的内部分化和外部泛化的＂身份危机＂。基层电大教师的教学工作和课程开发明显分离,网络教学新的特征和内涵进一步细化了电大教师的角色,教师岗位职能的细化使教师角色同一化,基层电大大量的管理工作进一步泛化了教师的角色,这些都不利于教师的专业发展。基层电大应通过纯化教师角色和控制教师工作量来提高外部认同度,通过建立教师专业发展标准和教学知识评价机制、重视教学理念的先进性、强调教学创新能力来提高内部认同度。  相似文献

An analysis of the nature of classroom activities: A comparative study of an immersion English class and a non-immersion English class in the mainland of China     

Xiaohua Liang 《Frontiers of Education in China》2011,6(2):310-330

This study was designed to investigate the nature of activities in an immersion English class and a non-immersion English class in the mainland of China, and to find out the differences between these two types of class through data gained from observation and interviews. Spoken discourse analysis was used to analyze the data, where Engeström??s activity complex system was used as the analytical framework to examine the nature of activities in the two types of classes. The results showed that it is the dynamic and situated nature of activity that makes a difference between the activities in these two classes. The interaction among the activity components, the social relations emerging through the process, the use of target language as the main mediational tool, and the subject content revealed in the activities enhance our emic understanding of the nature of activities. Implications can be drawn for English language teaching and for students?? English language learning for the schools in the mainland of China. This study contributes to both immersion education and classroom interaction.  相似文献

Guideposts and Roadblocks to the Career-Long Scholarly Engagement of Physical Education Teacher Education Faculty     

Catherine P. Berei  Erica Pratt  Melissa Parker  Kevin Shephard  Tanjian Liang  Udon Nampai 《Research quarterly for exercise and sport》2017,88(4):455-467

Purpose: Scholarship is essential for the growth and development of the physical education field. Over time, scholarship expectations have changed, forcing faculty members to alter time spent for research, teaching, and service. Social-cognitive career theory (SCCT) presents a model for understanding performance and persistence in an occupational environment. The interconnected aspects of SCCT have different emphasis related to self-efficacy, outcome expectations, or personal goals pursuit. This study explored physical education teacher education (PETE) faculty members’ continuing engagement in scholarly activity through SCCT. Method: Data collection included interviews with 9 senior PETE faculty members who met the criteria for “productive scholars over time.” Curriculum vitae were collected to verify productivity. Results: Data analysis revealed guidepost themes that included collaborating, finding balance, defining a research process, and maintaining a strong work ethic. Roadblocks encountered included other obligations and lack of support for research. Conclusions: Participants demonstrated strong self-efficacy; held high, positive expectations for success; and set very specific, clear, and deliberate goals. Participant behavior was moderated by their personal attributes (capacity to build relationships, set goals, and maintain interest and passion) and was tempered by the environments in which they worked. Fostering similar behaviors has the potential to guide future and current PETE faculty members in creating supportive and encouraging atmospheres for sustained productivity. The lack of literature relating to this topic warrants the need for more research exploring the influential factors and benefits gained from sustained scholarly productivity over time for PETE faculty members.  相似文献   

有氧体育锻炼与大学生执行功能关系的“剂量效应”研究     

刘俊一 《北京体育大学学报》2017,40(1):58-64

摘要：目的：探讨有氧体育锻炼与执行功能的“剂量效应”。方法：采用追踪研究设计，以270名大学生为被试，按性别、锻炼强度、频率、时间分成18个实验组，进行16周有氧功率自行车锻炼计划。使用Flanker任务、2-back任务和More-odd shifting任务在锻炼前、1次锻炼后、8周、12周和16周分别测试被试的抑制、刷新和转换功能，考察有氧体育锻炼对执行功能的影响。结果：强度、频率和时间对执行功能提高的贡献分别为0.927、0.872、0.813；强度主效应下，男大学生执行功能改善效果为大强度>中等强度>小强度，女性则为中等强度>小强度>大强度；频率主效应下，男、女大学生改善效果为高频率>中等频率>小频率；时间主效应下，男、女大学生改善效果为16周>12周>8周>4周>1次。结论：小强度高频率有氧体育锻炼适用于女大学生的运动干预方案，中等强度中等频率则适用于男大学生的运动干预方案，且以12周为单元周期。  相似文献   

文化“双核”理论视阈下我国龙舟体育文化传承的内容逻辑及范式研究*     

周次保  王亮  魏瑶  刘明 《广州体育学院学报》2016,(3):33-38

从文化“双核”理论的视角看,我国龙舟体育文化的传承内容及范式是龙舟体育文化人才培养工作的关键问题之一.运用文献研究、问卷调查、专家访问、数理统计与逻辑分析等方法,对我国龙舟体育文化的传承内容及范式进行了深入探讨.结果表明:我国龙舟体育文化传承的主要内容包括龙舟精神文化、龙舟竞渡文化、龙舟教育文化、龙舟娱乐文化、龙舟物质文化与龙舟经贸文化等六类亚文化及其它们所涵盖的二十种具象文化.而我国龙舟体育文化传承的基本范式可概括为基于血缘关系的宗族传承范式、基于自在自发的民间传承范式、基于政府促进的社会培养范式与基于学校领域的教育培养方式.廓清上述龙舟文化的传承内容及范式对于当下我国龙舟体育文化传承人才培养工作面临的难题破解具有重要价值.  相似文献   

成本分担视角下我国体育资金承载力预判与多元化来源研究     

刘亮  付志华  王飞 《成都体育学院学报》2017,43(2)

论文回溯了我国体育资金来源的历史演变过程,从财政性体育经费与非财政性体育经费两个层面梳理了我国体育资金的来源现状.并结合发达国家体育经费来源变化趋势、我国经济发展转型、国家新型城镇化发展战略以及体育资金潜在需求预测的阐述,分析了我国当前体育资金来源结构的承载力,指出单一性的资金来源结构已经难以肩负起"十三五"期间建设"健康中国"的重任.论文在剖析体育资金成本分担理论与现实依据的基础上,从以下3个方面提出我国体育资金来源的政策性建议:(1)积极培育体育市场,唤醒"沉睡"的资金;(2)推进体育体制改革,撬动社会资本的力量;(3)引导公众体育消费观念,拓宽资金来源渠道.  相似文献   

Wearable skin-like optoelectronic systems with suppression of motion artifacts for cuff-less continuous blood pressure monitor     

Haicheng Li  Yinji Ma  Ziwei Liang  Zhouheng Wang  Yu Cao  Yuan Xu  Hua Zhou  Bingwei Lu  Ying Chen  Zhiyuan Han  Shisheng Cai  Xue Feng 《国家科学评论(英文版)》2020,7(5):849

According to the statistics of the World Health Organization, an estimated 17.9 million people die from cardiovascular diseases each year, representing 31% of all global deaths. Continuous non-invasive arterial pressure (CNAP) is essential for the management of cardiovascular diseases. However, it is difficult to achieve long-term CNAP monitoring with the daily use of current devices due to irritation of the skin as well as the lack of motion artifacts suppression. Here, we report a high-performance skin-like optoelectronic system integrated with ultra-thin flexible circuits to monitor CNAP. We introduce a theoretical model via the virtual work principle for predicting the precise blood pressure and suppressing motion artifacts, and propose optical difference in the frequency domain for stable optical measurements in terms of skin-like devices. We compare the results with the blood pressure acquired by invasive (intra-arterial) blood pressure monitoring for >1500 min in total on 44 subjects in an intensive care unit. The maximum absolute errors of diastolic and systolic blood pressure were ±7/±10 mm Hg, respectively, in immobilized, and ±10/±14 mm Hg, respectively, in walking scenarios. These strategies provide advanced blood pressure monitoring techniques, which would directly address an unmet clinical need or daily use for a highly vulnerable population.  相似文献   

日本町村聚落演变特征分析     

李亮  谈明洪 《中国科学院大学学报》2020,37(6):767-774

伴随快速城市化的乡村聚落的衰落是社会各界关注的一个焦点问题，为了缓解这种现状，国家提出乡村振兴战略。那么，在乡村振兴中如何看待村庄的衰减？如何合理布局村庄和促进乡村振兴呢？日本作为一个城市化高度发达的国家，经历了乡村衰落和町村合并，该历程可能对中国有所启示。分析日本过去近100年不同等级町（镇）村数量变化、人口数量变化、空间分布与变化特征，以及町村聚落变化的影响因素；然后从4个方面探讨日本的经验对中国的启示：1）町村规模越大，在时序上衰落（数量减少）越滞后，但2000年以后（城市化后期阶段）不同规模等级的町村都在减少；2）1980-2015年町村数量减少率由东北向西南递增。其中，减少率最高的区域为濑户内海两侧地区，均高于80%；3）1980-2015年町村人口增长的主要区域分布在都市地区（东京都都市圈、名古屋都市圈、大阪都市圈），且离都市圈越近人口增长率越高；4）城市化快速发展、町村合并及选择性的乡村振兴是导致町村变化的3大原因。  相似文献
