Reflectors as online extraverts?     

Kevin Downing 《Educational studies》2004,30(3):265-276

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.  相似文献

浅谈初中数学作业的批改     

陈利涛 《中国基础教育研究》2007,3(8):151-151

批改作业是数学教学的一个重要组成部分。“全批全改”存在教师费时多、学生被动、师生双方获得的信息失真的问题。因此可以采用随堂批改作业、小组批改作业、教师抽查或面批，再由学生组成信息小组，及时交流信息的方法进行改革。  相似文献

Maintaining teachers’ face in the context of change: results from a study of Vietnamese college lecturers’ perceptions of face     

Thi Quynh Trang Nguyen 《Teachers and Teaching》2017,23(1):78-90

Gaining and saving face are very important in Vietnam as a mechanism of social control, including the professional behaviour of teachers. Interviews with 15 lecturers (aged 24–37) at a teacher training college in a Central Coast province of Vietnam illustrated the relationship between their concepts of face and their beliefs about good teaching. Most were still strongly influenced by traditional Confucian beliefs about the role and position of teachers, the nature of teachers’ knowledge and the relationship between teachers and students. On the other hand, some teachers also were aware of, and to a limited extent open to, more modern ideas that seemed to be related to broad social changes and reforms in approaches to teaching and learning in recent decades in Vietnam. The findings suggest that some teacher educators are uncertain about the value of traditional professional wisdom in the context of critical changes in society and in education. The research also suggests that the concepts of face and saving face are important for teachers’ sense of agency, and that Vietnamese educational authorities could increase the effectiveness of innovations in teacher education by paying attention to the influence of concepts of face on the teachers’ beliefs and behaviours.  相似文献   

论片面共犯的理论基础及其实践意义     

王娟 《丹东师专学报》2006,8(1):10-13

片面共犯应作为共同犯罪的一种特殊形式予以肯定。片面共犯区别于完全的共同犯罪，但有其存在的理论基础，符合共同犯罪的构成要件，并且当今的现实社会中存在着大量的片面共犯的现象。因此，应肯定片面共犯学说，完善共同犯罪理论。  相似文献
