| Abstract | 写作是重要的语言输出形式之一, 英语写作也是英语学习及英语考试的重要组成部分。二语习得中，主要使用准确性、流利性和复杂性三个指标衡量写作语言能力的发展。其中，复杂性通常包括句法复杂性和词汇复杂性。
本调查研究以输出理论和动态系统理论为基础，旨在分析英语学习者写作中的句法复杂性与词汇复杂性的纵向发展轨迹，主要回答以下两个问题：（1）通过一个学期的写作练习，学生的英语作文句法复杂性呈现怎样的变化模式？（2）通过一个学期的写作练习，学生的英语作文词汇复杂性呈现怎样的变化模式？本调查采用六项指标测量句法复杂性；采用两项指标测量词汇复杂性。
本调查的发现主要包括以下四个方面：（1）经过一学期的写作训练，学生的英语写作句法复杂性有增长趋势，轨迹呈非线性发展。（2）词汇复杂性有增长趋势，轨迹呈非线性发展。（3）句法长度指标的发展轨迹基本呈线性发展，其他指标的轨迹均呈非线性发展，每项指标的发展轨迹都不相同。（4）批改网系统提供的反馈中，学生比较认可的修改意见集中在词汇，语法方面，故促进了学生词汇复杂性的提高。本调查结果及发现对英语写作教学有实际意义及教学启示。 |
| Other Abstract | Writing is one of the most important language output forms, and English writing is an essential and important part of English examinations. In SLA (second language acquisition), language proficiency is always measured by accuracy, fluency and complexity. Complexity usually includes syntactic and lexical complexity. As to syntactic complexity, researchers put forward different definitions which share some common points in measurement indicators, such as length of T-unit, sentence embedded degree and structural type range. As to lexical complexity, its definitions mainly comprise lexical variation and sophistication. In recent years, researches on writing complexity are increasing gradually. Some researchers discuss the writing complexity development of learners at different grades or levels, while others study the writing complexity development from the perspective of topics, learners’ background, or teaching methods.
Based on the Output Theory and Dynamic Systems Theory, the present research aims at investigating the change of learners’ writing complexity, specifically, the development path of syntactic complexity and lexical complexity, and attempts to answer the following two questions: (1) Through a semester’s writing practice, how does syntactic complexity of students’ writings change? (2) Through a semester’s writing practice, how does lexical complexity of students’ writings change? Research materials are collected from the Pigai website, on which thirty students have finished fifteen writings during one semester, while seven of them, that is, once every two weeks, are chosen. A questionnaire is administered to investigate students’ familiarity of writing topics and their attitudes and opinions toward writing practices during the semester. Six indicators are adopted to calculate syntactic complexity: Mean Length of T-unit (MLT), Mean Length of Clause (MLC), T-unit Complexity Ratio (C/T), Dependent Clause Ratio (DC/C), Verb Phrase per T-unit (VP/T) and Complex Nonimals per T-unit (CN/T). Two indicators are adopted to calculate lexical complexity: Type-Token Ratio (TTR) and Lexical Frequency Profile (LFP). With regard to statistics, SPSS 11.5 is used to make data analyses involved in each indicator; and office software Word and Excel are used to handle the data and draw the development curves. Results show that the developmental paths of syntactic and lexical complexity are almost non-linear and fluctuant. Moreover, the results prove the dy... |
