场依存性、场独立性与商务英语阅读教学

不同的学习目标、不同的学习任务和不同的学习环境,需要不同的认知风格和学习策略。在商务英语阅读教学中,关注学生的个别差异,利用认知风格中的场独立性和场依存性的理论指导阅读教学有其重要意义。教师的教学应结合学生的认知方式的特点,以培养提高学生的阅读理解能力。教师对学生认知方式的了解和尊重,能使自己的教学特点与学生的需要有机地联系起来,建立良好的师生关系,根据学生的认知特点因材施教,就能取得好的教学效果。     

Dialogic processes that enable student teachers' learning about pupil learning in mentoring conversations in a Lesson Study field practice

This study investigates dialogic processes in student teachers' mentoring conversations in field practice, where Lesson Study (LS) was used as a context for establishing a dialogic learning community in one student group in science. We apply an analytical framework associated with Sociocultural Discourse Analysis to identify utterances that have the potential to create a dialogic space and contribute to ‘interthinking’ among the participants. The findings show the important role of the mentor teacher as a facilitator and a ‘knowledgeable other’, challenging the student teachers to reflect on chosen activities using predictions and detailed observations related to pupils' learning.     

文本内外的双重幻灭——关于《生死场》、《呼兰河传》和《小城三月》的连续性解读

站在女性关注的立场,萧红的《生死场》、《呼兰河传》和《小城三月》这三部作品之间有着紧密的连续性。一方面,顺着作品本身的思路,这三部小说表达着萧红对于女性由受压迫到觉醒再到幻灭的命运的思考,另一方面,联系萧红的亲身经历,这三部小说又埋藏着她自身理想一步步破灭的悲剧。文本内的被思考者和文本外的思考者的双重悲剧呼吁着整个社会和女性自身对女性独立给予更多的关注和更大的空间。

Bridging In-school and Out-of-school Learning: Formal, Non-Formal, and Informal Education

The present paper thoroughly examines how one can effectively bridge in-school and out-of-school learning. The first part discusses the difficulty in defining out-of-school learning. It proposes to distinguish three types of learning: formal, informal, and non-formal. The second part raises the question of whether out-of-school learning should be dealt with in the in-school system, in view of the fact that we experience informal learning anyway as well as considering the disadvantages and difficulties teachers are confronted with when planning and carrying out scientific fieldtrips. The voices of the teachers, the students, and the non-formal institution staff are heard to provide insights into the problem. The third part discusses the cognitive and affective aspects of non-formal learning. The fourth part presents some models explaining scientific fieldtrip learning and based on those models, suggests a novel explanation. The fifth part offers some recommendations of how to bridge in and out-of-school learning. The paper closes with some practical ideas as to how one can bring the theory described in the paper into practice. It is hoped that this paper will provide educators with an insight so that they will be able to fully exploit the great potential that scientific field trips may offer.

网络科技信息结构化监测的思路和技术方法实现

网络科技信息具有开源、发布及时等特点,目前已成为战略情报监测的重要资源。但这类资源又具有非结构化、无语义描述等特点,如何将Web信息从非结构的自由信息转为可分析的结构化、语义化信息成为一个亟需解决的问题。针对这一问题,笔者提出了网络科技信息结构化监测的思路方法。这一方法通过知识抽取技术,从网络信息资源中抽取出嵌在其中的知识对象以及对象间的相互关系,将自由文本转换为结构化的可计算的知识单元,在此基础上构建各类监测模型,进而实现对研究领域的态势监测。基于这一思路,笔者开发了“网络科技信息自动监测系统”,并基于监测数据所形成的语义资源,进行了监测态势分析实验。图 6。表1。参考文献16。     

关于中国近代史上限的几点思考

“近代”一词有两种含义，指时间或社会发展形态。中国史学界“近代”、“现代”说法的指称对象虽渐趋一致，但实际教学、科研中，二者相混，难以硬性规范。“近代”应明确为指半殖民地半封建社会史，其上限以鸦片战争为标志，但只具相对意义，近代史时段－鸦片战争至中华人民共和国成立，亦不能作僵化理解，应根据具体研究对象来确定研究的时空范围，淡化“上限”概念，拓展中国近代史研究视野，在理为 宏大的历史时空中考察中国近代社会历史的走向，将是中国近代史学科新的突破和发展的契机。
