英语作文自动评价反馈对学生词汇修改的影响——以批改网为例

71英语作文自动评价反馈对学生词汇修改的影响*——以批改网为例黄爱琼 张文霞(清华大学 外文系,北京 100084)摘要:文章通过对调查问卷、总结报告和访谈记录的分析,对37名学生基于英语作文自动评价(Automated Writing Evaluation ,AWE )反馈的写作过程进行了探讨,并以批改网为例,重点研究了AWE 提供的词汇反馈点和AWE 提供的反馈对学生的词汇修改的影响这两个问题。
文章研究的结果表明,批改网提供的词汇反馈点主要为学习资源反馈点,给予的词汇警示和词汇错误反馈点主要集中于名词、冠词、动词和搭配错误;学生比较关注批改网反馈给予的词汇错误和词汇警示,反馈有助于提升文本词汇的多样性和复杂性,学生对涉及单词、搭配/短语的反馈比较满意。
此外,文章还讨论了AWE 反馈影响学生词汇修改的相关因素,以期有针对性地发挥AWE 反馈的积极作用,提升学生的英文写作水平,更好地开展大学英语写作教学。
关键词:作文自动评价反馈;大学英语;词汇修改;批改网【中图分类号】G40-057 【文献标识码】A 【论文编号】1009—8097(2018)07—0071—08 【DOI 】10.3969/j.issn.1009-8097.2018.07.011在当前国内的英语写作教学中,教师批改作文的工作量大,无法提供及时有效的反馈[1]。
杨永林等[2]提到英语教师批改作文的三项基本功是“准确判断、精准修改、合理建议”,而要满足这三项标准需要3~5年的严格训练,因此“有必要借助智能化的文章批改利器,来缓解这个问题”。
相较于传统的教师反馈,人工智能(Artificial Intelligence ,AI )辅助批改作文和计算机辅助语言测试具有既省时又省力的经济价值[3],因而在当代英语教学中得以迅速推广。
随着AI 的不断开发利用,尤其是利用计算机技术对作文进行评估和记分[4]的AWE 的研发和应用,使计算机辅助英语教学和测试的局限性得以逐渐突破,说和写的潜力(即输出性能力)得以深入挖掘和利用。
ai 批英语作文

AI助力英语作文批改:提升写作技能的新时代In the age of technology, artificial intelligence (AI) has made significant strides in various fields, including education. One such application of AI is in the realm of essay grading, particularly when it comes to English compositions. AI-based essay grading tools have the potential to revolutionize the way students learn and improve their writing skills.Firstly, AI grading tools can provide instant feedback to students, enabling them to identify and correct errors promptly. Unlike traditional grading methods that often take days or even weeks, AI tools can analyze and provide feedback on essays almost instantaneously. This prompt feedback loop allows students to iterate on their writing and refine their ideas more efficiently.Moreover, AI grading tools can provide detailed feedback on various aspects of writing, such as grammar, vocabulary, sentence structure, and content coherence. These tools are not just limited to surface-level errors; they can also analyze the depth and quality of content,offering insights into areas where students can improve. This comprehensive feedback helps students to develop a more nuanced understanding of their writing strengths and weaknesses.Additionally, AI grading tools can adapt to the unique writing styles and preferences of individual students. By analyzing a student's past writing, these tools canidentify patterns and trends, allowing them to provide more personalized feedback. This personalization ensures that each student receives feedback that is tailored to their needs and helps them to develop their unique writing voice. However, it is important to note that while AI grading tools offer significant advantages, they should not completely replace human grading. Human graders still have the ability to understand and interpret the nuances of language and writing that AI tools may miss. Moreover, human graders can provide emotional support and encouragement that is crucial for students' motivation and engagement.In conclusion, AI-based essay grading tools hold great promise for enhancing students' writing skills. These toolsprovide instant, detailed, and personalized feedback, enabling students to improve their writing efficiency and quality. However, they should be used as complements to human grading rather than replacements. By leveraging the power of AI, we can usher in a new era of writing instruction that is more efficient, personalized, and engaging for students.**AI助力英语作文批改:提升学生写作技能的新时代** 在科技日新月异的时代,人工智能(AI)已在各个领域取得了显著进展,其中包括教育领域。

人工智能智慧批改作文800字

人工智能智慧批改作文800字英文回答:Artificial intelligence (AI) has revolutionized various aspects of our lives, and one of its applications is intelligent essay grading. This technology utilizes machine learning algorithms to analyze and evaluate essays, providing feedback and scores to students. Let's delve into the advantages and challenges of AI-powered essay grading.Firstly, AI can save teachers' time and effort. Grading a large number of essays can be a time-consuming task for educators. With AI, essays can be graded automatically and instantaneously, freeing up teachers to focus on other important aspects of their work. This efficiency allows for faster feedback, enabling students to learn from their mistakes and improve their writing skills more effectively.Additionally, AI-powered essay grading can provide consistent and unbiased evaluations. Human grading can beinfluenced by various factors, such as mood, personal preferences, or even handwriting. AI, on the other hand, follows a set of predefined criteria and evaluates essays objectively. This ensures fairness in the grading process and eliminates potential biases.Moreover, AI can offer personalized feedback to students. By analyzing the content, structure, and grammar of an essay, AI algorithms can identify specific areas for improvement. This tailored feedback helps students understand their strengths and weaknesses, enabling them to focus on specific aspects of their writing that need improvement. This individualized approach enhances the learning experience and fosters students' growth.However, AI-powered essay grading also faces some challenges. One major concern is the ability to accurately assess the quality of complex and creative writing. While AI algorithms can effectively evaluate grammar, spelling, and basic structure, they may struggle to understand and appreciate nuanced arguments or creative expressions. This limitation highlights the importance of human involvementin the grading process, as teachers can provide valuable insights and feedback that AI may not capture.In conclusion, AI-powered essay grading offers numerous benefits, including time-saving, unbiased evaluations, and personalized feedback. However, it is important to recognize the limitations of AI in assessing complex writing. Therefore, a hybrid approach that combines AI technology with human expertise seems to be the most effective method for intelligent essay grading.中文回答:人工智能(AI)已经在我们生活的各个方面带来了革命性的变化,智能批改作文就是其中之一。

77一、英语写作现状在很多英语考试中,英语作文裸考现象很普遍。
尤其是中学学生,由于学习科目较多,时间和精力有限,而写一篇作文耗时耗力,写完后又得不到老师及时细致的批改反馈,严重挫伤了学生练习写作的积极性。
学生通常都是在考前练习几篇写作题目,或者背诵范文。
目前,英语师生人数比例失衡严重,学生多,英语老师少,再加上老师的教务、科研等工作,英语作文经常面临老师布置习题,但难以有效大量批改的问题。
进一步导致学生英语写作水平较差,作文均分不及格。
近几年实施的新高考英语改革提升了英语作文分数,增加了作文篇数,强调对学生应用能力的培养,作文分值由原来的15-25分提升到35-40分。
在大部分高校,写作是公共英语课程主要考核方式之一。
北京市海淀区英语教研员刘晓波曾说过,“得作文者得天下”。
英语写作在英语教学和考试中越来越重要,提升英语写作水平对提升学生英语综合能力的重要性不言而喻。
二、批改网是什么批改网是一款能够提供即时反馈的英语作文智能批改系统批改网是一款智能批改英语作文的在线服务系统,能够有效提高教师的批改工作效率,提高学生的英语写作能力。
对于学生而言,批改网能够在1秒内对作文给出分数、批改网:英语作文智能批改□文/张跃北京语言智能研究院执行院长、批改网创始人。
硕士毕业于东北大学,曾任职于微软亚洲研究院和奇虎360公司,从事自然语言处理和搜索相关技术研究。
目前专注于英语作文的智能批改相关研究,其团队开发的批改网已累计批改作文超过5.3亿篇,已被6000多所学校、2000多万名学生所使用。
张 跃随着人工智能的介入,传统的教育模式正在发生巨大的变化,深度学习、自然语言处理等技术让固有的教与学方式产生了新的变革,智能化的教学方式为个性化教学提供了新的可能性。
本文以批改网的英语作文智能批改系统为例,阐述智能化教育是如何突破传统教育模式在时间与空间上的限制,为学生提供更为公平、有趣、个性化的教育的。
76图1:英语作文在批改网批改后的反馈评语和按句点评的反馈。
该系统拥有192个以上的评分维度,通过机器学习可以使用测试环境下的评分要求,并且给予庞大的标准语料库,对学生文中包括中式英文在内的语言问题进行精准判断,并给出修改反馈。
批改原理批改网是由北京词网科技有限公司完全自主研发的英文作文智能批改系统,其核心功能为英语作文智能评分与点评,使用到的核心技术有自然语言处理(NLP,Natural Language Processing)技术、深度学习技术、云计算技术等。
其中批改网是NLP 技术的典型应用,大量综合应用词性标注、句法分析、自然语言生成、文本分类、信息检索、信息抽取、文字蕴含等对应的处理技术和研究成果。
批改功能的批改原理为将用户提交的学习者语料用数据处理后和标准语料数据(母语用户语言资源库)进行比对分析,测量出两者之间的“距离”数据。
然后用一定的分析规则将“距离”映射转化为用户可理解的分数、总评语、按句评语等反馈内容。
映射转化时则依据的是192个语言分析维度。
所以从直观上讲,一篇作文距离标准语料库越远,分数越低,反之则分数越高,如图2所示。
批改网系统体系结构批改网系统主要分为5大模块,分别为:作文分析模块、对比模块、打分模块、数据挖掘模块和知识运维库模块,具体如下:作文分析模块:主要对作文进行整体的分析,分析内容包括词汇、词块、搭配、句型等内容;对比模块:根据作文分析模块分析到的内容,调用知识运维库里相应的数据与作文内容进行对比,找出作文存在的亮点及不足点,并给出相应提示;打分模块:系统在对作文进行分析对比后,会根据教师设置的打分权重对作文进行打分;数据挖掘统计模块:数据挖掘统计模块主要是统计系统对作文的分析结果,并对分析结果进行整理,生成详细的图文报表;7879知识运维库模块:主要为系统对比模块运行提供数据支持。
用户可以将自己的经验提交到知识库里,系统会自动将其记录并用于作文对比,用户提供的数据越多,提供的分析反馈就越详细,学生获得的知识也就越多。
按句点评及中式英文识别技术能够即时给出文章全面的按句点评反馈是批改网一个重要的技术创新点,批改网采用大数据分析、深度学习等技术对大量的学习者语料数据和标注语料数据进行对比分析,得出一个可实时更新且记录的语言粒度更细、规模更大,并可以识别由于文化差异造成的语言用法问题(如中式英文)的知识库(错误库)。
在批改网中用户提交的待分析文章被标注处理后,批改引擎会先根据知识库(错误库)中记录的各种语言分析规则点分析文中语言特点,并自动生成各种情况的反馈内容,最终形成文章批改后的按句点评内容,而每一篇被分析过的学习者文章也会最终进入学习者语料库,进一步丰富学习者语料库。
批改网使用概况截至目前,批改网已经在国内大学、中学的英语老师和学生间得到广泛使用,包括图2:批改网打分原理图3:批改网体系结构8081的学习效果。
即时反馈刺激学生自主学习行为的发生学生的学习受多方面因素的影响,其中主要是受学习动机的支配。
学习动机是指直接推动学生进行学习的一种内部动力,是激励和指引学生进行学习的一种需要。
在英语写作中,即时反馈能为学生提供学习动机,系统的即时反馈刺激学生不断修改、不断完善,以达到分数提高的目的。
而这种动机也可以理解为游戏攻关心态,学生整个写作提分的过程就像一个游戏闯关的过程,分数每提高一点,就像闯过一个关级,这对学生是一种激励,刺激学生自主学习行为的不断发生。
学生在批改网提交作文后,不仅能实时查看自己的成绩,还能查看自己在班级里的排名。
在一个寝室里,有的学生第一次提交就得到90多分,而有的学生只得到70多分,这个学生就努力修改以提高分数。
系统的即时反馈激励着学生不断修改,赶超他人,提升自己的写作成绩。
四、批改网使用案例分析批改网多元评价技术:清华大学张文霞教授的“五步作文法”清华大学外文系张文霞教授在英语写作与现代化教育技术相融合的教学研究方面进行了有效的理论和实践探讨。
她是清华大学最早将批改网引入本科英语写作教学的老师,特别是引入了人机共评的多维度、多模态写作评价模式实践,取得了良好的教学效果。
批改网支持多元的评价方式,通过“教师点评+同伴互评”的学习活动方式,有利于提高学习者的迁移学习能力。
教师以学习者的作文被自动批改后的评价结果为参考,进行人工批改、打分、写评语。
同时,教师通过“随机分配”和“指定分配”两种方式,发起同伴互评的在线教学活动,要求学习者在规定的时间内完成作文评价的任务。
张文霞[3]教授根据“以评促学”理论,在批改网多元评价技术的支持下设计了“单周写作,双周评议,其间多元反馈评改,然后阶段性反思自评”的过程化施教方案。
根据“社团学习”和“临近区域”理论,在课堂教学中,由教师和助教一比一配对的“教研团队”,以学生为中心,在一个学期中,通过师生团队协作共同提高写作技能。
基于批改网多元评价技术和过程化施教方案,张文霞教授向学生推行了“五步作文法”,如图6所示:清华大学、北京大学等众多名校已经将“批改网”融入日常教学,有来自全国6000所学校的20万名教师和2000万名学生使用批改网,累计批改作文超过5.3亿篇,批改网已然发展成为中国最大的英语写作学习平台。
每天都有几十万名学生在批改网上提交作文。
图4展示了学生在批改网上提交作文的实时动态:批改网能够即时批改学生作业,并通过时间轴的方式记录学习者的成长轨迹,以某位学生的一篇作文为例,经过150次的修改,该学生的作文分数从30分提升到73.5分。
三、即时反馈的重要性实现交互式学习中国人工智能学会理事长李德毅院士说过:“教育的本质就是交互认知 [1]。
”交互式学习是一种强调结合交际合作和电脑使用的新型教学方式。
批改网系统通过给学生提供即时反馈,让学生能够及时了解和修改错误点,通过“提交批改-获得反馈-修改完善”的循环,在与机器不断的交互中实现交互式学习。
提高学习效率,提升学习效果国家基础教育课程教材专家工作委员会委员、教育部《高中英语课程标准》修订组核心成员夏谷鸣曾表示,在英语学习中,如果没有指导性的建议和即时反馈,学生的学习行为大多是在同一水平的简单重复,导致同样的错误重复犯。
在二语习得领域有一个很著名的U-shape[2]理论,这个理论表明学生在掌握一个语言知识点时,通常会经历一个“对-错-对”的过程。
批改网能够即时批改学生作业,并通过时间轴的方式记录学习者的成长轨迹,有助于增强学习者的学习成就感和体验感。
学生在面对第一版分数相对较低的作文时,通过机器批改提示进行自主学习,作文成绩提升,在收到鼓励的同时,形成了习得的过程。
这极大地提高了学习效率,提高了学生图6: 张文霞教授的“五步作文法”[1]视频网址:https:///v_show/id_XMTY3MDc4OTY2MA==.html[2]Millians M. U-Shape Learning[J]. Encyclopedia of Child Behavior & Development, 2011:1525-1527.[3]张文霞,黄静:“构建信息技术在大学英语课程中的运用框架”[J].《现代教育技术》,2014,24(1):75-83图4:批改网用户实时提交数据(网址:/?a=pad3)图5:某位学生的作文成绩轨迹(修改次数:150次;分数:30—73.5分)8283该作文法让学生在完成作业的过程中,先在批改网上提交作文,并根据系统反馈修改作文,然后由同组同学互评,到助教点评,再到学生自己评价,最后由老师对文章做全面点评。
在循序渐进的交流学习中,每个人都能得到语料库、同学和老师的同时反馈,写作水平会得到较大提升。
这样的互动学习模式得到了同学们的广泛好评:“课堂很轻松,也能学到不少东西。
每次作文先自己写,然后在网上修改、同组互评,再经老师评审,受益颇丰。
”同时,清华大学还规定学生需根据批改网给出的反馈对作文进行修改,分数低于85分则不算提交了作文;在批改网上提交的作文分数低于90分者,不准参加论文和作文的答疑;批改网的作文成绩算入平时分,取最高4次作文成绩的平均分算作平时分,这也体现了形成性评估的教学方法。
批改网促进教育均衡发展:北京市朝阳区中考提分案例2015年至2016年,依托国家社科基金重大委托项目“语言大数据挖掘与文化价值发现”,批改网与北京市朝阳区多所学校开展了课题合作项目,针对该项目,批改网重点跟踪了23所学校,其中包括14所农村初中校和9所薄弱城市初中校。
通过让学生在批改网上进行写作训练,教师监督学生学习情况并调整改进英语写作教学方式方法,提升学生的写作积极性和自主学习能力。
在整个课题合作中,批改网收到北京市朝阳区的22460篇学生作文,涵盖了52所图7:批改网作文体检报告单中学,其中老师布置了713个题目,学生累积修改次数达到160599次,平均每人每篇作文修改约7.1次。
