发布时间：2018-11-08 14:27

【摘要】：当今英语已经成为世界上最广泛使用的语言。因为在各种交际活动中“听”占据了近一半的比例,越来越多的人开始意识到听力在英语学习中的重要性。新闻凭借其发音标准、获取便利等特点,逐渐被当作英语听力的学习材料。英语新闻已经引起了众多学者的关注,学者们从英语新闻特征和英语新闻教学的角度进行研究。现代教育观主张以学习者为中心,自适应学习作为一种以学习者为中心的学习方式,学习者可以根据自身兴趣和能力获得最优且最合适的学习材料。有些学者致力于自适应学习系统的设计、搭建与评价等,还有一些研究人员尝试搭建英语新闻语料库和英语新闻学习系统。随着信息技术的迅速发展,英语新闻自适应学习系统的开发与投入教学成为可能。本研究从英语学习者的角度出发,以探索高效提升其英语听力水平的途径为目的,搭建以英语新闻作为学习材料的自适应学习系统。本研究基于三个理论而展开,即教学过程最优化理论,建构主义理论和最近发展区理论,这些理论都注重个性化学习,强调对不同层次的学生采用不同的教材和方法。我们开发的自适应学习系统以英语新闻语料库为数据支撑,尊重学习者的个体差异,把学习者不同的需求、兴趣和能力等作为提供学习和听力资源的依据。该英语新闻自适应学习系统可以实现与学习者的互动,学习进度的自主调整,根据学习者的意愿提供自适应材料,对学习效果做出自适应评价,并匹配合适的听力练习。系统的操作流程简单方便,界面简洁明晰,学习者注册登录后,选择相关模块进行练习学习,系统记录学习情况,推送不同的学习材料。系统中的新闻语料库包含新闻、听力题和学习材料三个部分。语料库中的所有新闻都来源于知名且权威的渠道,学习材料则为新闻文体特征、新闻词汇、新闻结构和时事背景。为了便于检索,我们对新闻语料进行了分类和标注。英语新闻自适应学习系统有利于提升人们对以学习者为中心的教育的认知度,营造个性化的学习环境,为自主学习的实施搭建平台。而且,该系统还有助于提升学习者的英语听力能力,使学习过程更有针对性、更高效,同时为教师讲授听力课程和实施分层教学提供便捷且有效的资源。
[Abstract]:Nowadays English has become the most widely used language in the world. As listening accounts for nearly half of all communicative activities, more and more people are beginning to realize the importance of listening in English learning. News is gradually used as English listening materials because of its pronunciation standard and convenience. English news has attracted the attention of many scholars, who have studied the characteristics of English news and the teaching of English news. Modern view of education advocates learner-centered, adaptive learning as a learner-centered learning approach, learners can according to their own interests and abilities to obtain the best and most appropriate learning materials. Some scholars devote themselves to the design, construction and evaluation of adaptive learning systems, and some researchers try to build English news corpus and English news learning system. With the rapid development of information technology, it is possible to develop and put into teaching English news adaptive learning system. From the point of view of English learners, this study aims to explore ways to improve their listening proficiency efficiently and to build an adaptive learning system with English news as the learning material. This study is based on three theories: the theory of optimization of teaching process, the theory of constructivism and the theory of proximal development area. These theories all focus on individualized learning and emphasize the use of different teaching materials and methods for students of different levels. The adaptive learning system is based on the English News Corpus. It respects the individual differences of learners and takes the different needs, interests and abilities of learners as the basis for providing learning and listening resources. The English news adaptive learning system can realize the interaction with the learners, adjust the learning progress autonomously, provide adaptive materials according to the learners' wishes, make an adaptive evaluation of the learning effect and match the appropriate listening exercises. The operation flow of the system is simple and convenient, and the interface is simple and clear. After the learners sign up, they choose the relevant modules to practice and study, and the system records the learning situation and pushes different learning materials. The news corpus includes three parts: news, listening questions and learning materials. All the news in the corpus comes from well-known and authoritative channels, and the learning materials are news stylistic features, news vocabulary, news structure and current affairs background. In order to facilitate retrieval, we classify and annotate the news corpus. English news adaptive learning system is helpful to enhance people's awareness of learner-centered education, create a personalized learning environment, and build a platform for the implementation of autonomous learning. Moreover, the system can improve learners' listening ability, make the learning process more targeted and efficient, and provide convenient and effective resources for teachers to teach listening courses and implement hierarchical teaching.
