摘要
本文以210名不同汉语水平的韩语母语者为研究对象,采用相关和多重回归的统计方法,首先从总体上考察词汇多样性、词汇复杂性、词汇正确性、汉字正确性、语法正确性、句法复杂性6个语言特征与写作成绩、内容质量评分的关系,然后考察内容质量评分和写作成绩的相关关系,最后考察语言水平对6个语言测量指标和写作成绩关系的影响效应。研究发现,从总体上看,6个语言特征均与写作成绩、内容质量评分显著相关,并且都能显著预测写作成绩,其中汉字正确性、语法正确性和词汇正确性贡献程度最大,且前两者达到中等效应量。除词汇多样性外,其他5个语言特征都能显著预测内容质量评分,其中词汇复杂性贡献程度最大,达到中等效应量。内容质量评分和写作成绩达到高相关。另外,研究还发现语言水平与汉字正确性存在交互效应,与中高级水平相比,初级水平汉字正确性对写作成绩的预测作用更大。与此同时,本文结合学生作文表现、对评分员的访谈以及对测量指标内部构念的分析,对造成语言各维度对写作成绩和内容质量分数不同贡献程度的原因以及写作质量和内容质量的关系进行了相应的质性分析。
This research involves 210 South Korean speakers who are of different Chinese levels.A correlation and a linear regression analysis are conducted to explore the relationship between six language features(lexical diversity,lexical sophistication,lexical accuracy,Chinese character accuracy,grammar accuracy,and syntactic sophistication),writing score and content score.Then the relationship between content score and writing score is explored,which is in turn followed by an analysis of the effect of Chinese level on the relationship between language features and writing score.The results show that all six language features are significantly correlated with writing score and content score and can predict writing score effectively.Of the six features,Chinese character accuracy,grammar accuracy and lexical accuracy contribute the most,with the former two achieving medium effect size.Except lexical diversity,the other five language features can all predict content score,lexical sophistication contributing the most to achieve medium effect size.We also find high correlation between content score and writing score,as well as interaction effect between language level and character accuracy,in that character accuracy best predicts writing score on the basic level.In the mean time,by combining students' writing performance,interview with scorers,and an examination of the internal construct of measure indices,we make a quality analysis of the reasons for the different contributions of language features to writing score and content score,and the relationship between writing quality and content quality.
