Through the analysis of survey and interview data, we investigated the attitudes and perceptions of 32 multilingual teachers of Spanish in Belize, a code-switching (CS) context where Spanish is in intense contact with English and Belizean Kriol. More specifically, we examined teachers’ and students’ attitudes toward Spanish and CS and teachers’ perceptions vis-à-vis students’ attitudes toward Spanish instruction. The study revealed that whereas some teachers held negative views of Northern Belizean Spanish, they did not markedly perceive standard Spanish as “better” than the local variety of Belizean Spanish. The analysis also showed that most teachers had a positive predisposition to the use of CS as a pedagogical tool in their classrooms, a finding that suggests that ultra-normative attitudes toward Spanish varieties are not prevalent among these educators. In view of students’ attitudes, teachers concurred that students had overwhelmingly negative attitudes toward standard Spanish, in line with previous findings. We argue that educational reforms and status-planning efforts are vital to destigmatize Spanish and to promote its maintenance alongside Belizean Kriol and English. 相似文献

Drawing on linguistic anthropological notions of language ideologies and sociolinguistic approaches to stance, this study examines the meaning-making resources through which Spanish heritage language (HL) learners orient toward ideological perspectives on language value and linguistic expertise in classroom interaction. Part of a larger ethnographic study, data in the present study include about 26 hours of audio and video recordings from three different intermediate Spanish HL classrooms and filmed interviews with the students. The analysis indicates that discourses of legitimacy and expertise are embodied within multiple levels of classroom interaction, including affective stancetaking, expert/novice positioning, and the reframing of both ascribed social positions and previous discourse. Results suggest that the role of language ideologies in HL learning can be better understood through an examination of stancetaking in interaction and that the construction of different kinds of expertise should be an important consideration in the development of HL instructional practices. 相似文献

Motivation, which is one of the individual differences, contributes a lot to the success and failure in second language learning. This essay focus on the discussion of the definition, types, effect and implications of motivation in second language learning with the aim of promoting learners' learning proficiency. 相似文献

The paper addresses severalethical issues in online communication researchin light of digital ontology as well as theepistemological questions raised by theblurring boundary between fact and theory inthis field. The concept of ontology is used ina Heideggerian sense as related to the humancapacity of world construction on the basis ofthe givenness of our being-in-the-world.Ethical dilemmas of Internet research thusarise from the tension between bodily existenceand the proper object of research, i.e., onlineexistence. The following issues are beingconsidered: online identity, online language,online consent and confidentiality. We alsoargue that research ethics in the US followsthe utilitarian tradition, while Europeanresearchers are deontologically oriented. Aguideline of best practice in online researchethics is proposed. 相似文献

In this paper, we propose a new language model, namely, a dependency structure language model, for topic detection and tracking (TDT) to compensate for weakness of unigram and bigram language models. The dependency structure language model is based on the Chow expansion theory and the dependency parse tree generated by a linguistic parser. So, long-distance dependencies can be naturally captured by the dependency structure language model. We carried out extensive experiments to verify the proposed model on topic tracking and link detection in TDT. In both cases, the dependency structure language models perform better than strong baseline approaches. 相似文献

美国伯克莱大学近年来开发设计的语义工具———入口词表模块(EVM),目标是实现自然语言到受控语言的转换。本文详细介绍了EVM的创建过程和实现机制,首先利用数据检索代理和清洗代理从远程数据库中下载记录;然后抽取代理和构建代理利用下载的数据,采用统计学的方法计算自然语言词汇和受控语言词汇之间的关系,构建关联词典;最后由桌面代理和领域代理提供给用户感兴趣的领域,帮助用户进行检索。另外还列举了目前已经建立的几种模块,如INSPEC、MEDLINE、PATENTS等。最后还提出了这一项目未来需要改进的工作。 相似文献
