在电脑与网络技术日益发达的今天，对外汉语写作教学也不可避免地受到了一些影响。既往有研究成果表明，留学生最常用的写作策略是工具策略。带着新环境下工具策略的变化及影响等诸多疑问，本文以留学生写作策略为研究方向，以工具策略为重心，通过工具策略问卷、写作需求问卷等一系列调查，深入分析工具策略变化的过程和现象，以期为写作教师及相关研究者提供有价值的信息，适时调整教学策略、教学模式、教学内容等要素，为学生提供一个高效、实用的学习体验。 本文首先对对外汉语写作教学及留学生学习策略的既往研究做了综述，列举了较为重要的专著和论文。 接着是基于问卷的写作工具策略分析。数据显示被调查者，在日常生活学习中，手写汉字的机会稍多于电脑输入，但是认为自己电脑输入速度更快的学生，明显多于手写；常用电脑的学生，出现负相关（常用电脑，但是用电脑输入速度慢）的情况比较少，而常用手写的学生，正相关（常用手写，且写手输入速度快）与负相关比率近似。可见倾向于电脑写，更易于产生马太效应的积累优势，倾向于手写则更易受环境影响产生动态变化。近半数学生对电脑输入汉字有一种主观期待，更倾向于认为用电脑输入汉字比手写简单，但仍有较多学生对两种方式产生的写作成果持不偏向的态度，说明部分学生对电脑输入的信心不足，还需要更多锻炼。 然后分析留学生工具策略变化产生的影响，主要体现在写作过程方面从“构思-查词典-写作-修改”到“网络搜索-比较资源-整理思路-写作-修改”；在写作语言方面选词范围扩大，易造成词汇的误用等；在写作目的方面，网络环境为有分享意愿的人提供了更多主动的写作体验。由此总结工具策略变化所带来的正面影响，如提高输入速度，减轻写作压力，增加写作素材和参照范例，扩大写作的实用性和交流的范围等；以及负面影响，如忽视手写汉字的训练会影响对汉字的掌握，出现同音错误，助长抄袭的不良习惯等。结合一篇电脑输入习作实例分析目前缺乏汉字电脑输入技巧指导的影响，主要体现在作文格式、标点符号的输入及文段引用方面。 接下来通过写作需求问卷了解学生的学习目的、写作习惯以及对教师的预期等主观因素，结合工具策略问卷的数据，从教学资源、教学方式、教材编写、练习及测试、评改与反馈等方面介绍实际教学中的尝试。

With the increasingly development of the computer and network technology，writing of teaching Chinese as a foreign language (TCAFL) is inevitably influenced. Some studies show that students prefer to use tool strategy rather than the other writing strategy. What happened during these changes and what did these changes cause then? To answer the question，this article made in-depth analysis on the tools strategy based on several surveys from the direction of writing strategy and expect to provide some practical information.Firstly this article reviews about previous studies on writing teaching and learning strategy of TCAFL, collecting important monographs and articles.Then based on the questionnaire, we find that more students prefer to use handwriting but much more students consider computer as a faster tool; students who often use computer can use it skillfully but if they often wrote by hand, we can not give a certain conclusion. So there is a superiority correlation with computer writing and a movement with handwriting under different circumstances. Nearly half of the students have certain expectations in computer input, who consider which is easier, but there are still a lot remained neutral because of the lack of confidence of computer input, who need more exercise.Then this article analyzes the impact of tools strategy change, mainly embodied in the writing process from "idea - dictionary - writing – to amend" to "Internet - resources compare - idea arrangement - writing - to amend". There are some positive effects, such as to improve input speed, to relieve pressure, to increase materials and reference example, etc; And negative effects, such as to ignore the importance of handwriting, homophones errors, etc. According to an example analysis of computer input to find the influence out of inadequate computer input skill training. And through themes in the questionnaires like learning purpose, writing habits and the expectation to teachers, this article analyzes the impact of these changes in aspect of teaching resources, teaching method, textbook, practice and testing, to provide some practical methods and materials.
