A Study On The Changes Of Korean Chinese Learners’ Cognate Phrase Acquisition In The Perspective Of Complex Dynamic Systems Theory

In recent years,exchanges between China and Korea have become more frequent,and the number of Korean learners has increased,so it is especially important to teach and research Korean learners in a nationalized way.Cognate phrases are a common type of phrases in Chinese,with distinctive form,unique language effect,and high usage frequency,and in recent years,the structure of cognate phrases in communicative use has become more complex and their language function has been further enhanced.However,there are few studies on the acquisition of cognate phrases by Korean Chinese learners,and it is difficult to guide the current practice of teaching cognate phrases in Chinese language teaching.Against this background,this paper investigates the acquisition patterns of Korean Chinese learners’ cognate phrases by using a corpus and other research methods supported by complex dynamic systems theory.Based on the corpus of different periods,we analyze the current situation of Korean Chinese learners’ use of cognate phrases and their tendency to complication,clarify the process of acquisition of cognate phrases by Chinese learners,and conduct a study on the change of acquisition to understand the trend of change,so as to find out the problems of Korean Chinese learners’ acquisition and explore the strategies of teaching cognate phrases accordingly.The article is divided into three parts,and the specific structure framework is as follows:The first part is the introduction,which mainly explains the background of the study,the current situation of the study,the research content and sources of the corpus,the research theory and research methods.The second part is the main body of the dissertation,which mainly includes five chapters.The first chapter examines the characteristic analysis and distribution of contemporary Chinese cognate phrases.This chapter briefly introduces the main features of cognate phrases,including composition,semantic and pragmatic analysis,and examines the use distribution of cognate phrases in contemporary Chinese in co-occurrence.Chapter 2 examines the acquisition of cognate phrases by Korean Chinese learners at the end of the 20 th century.Based on the theory of complex dynamic systems,this chapter provides a comprehensive analysis of the usage distribution,complexity and accuracy of learners’ cognate phrases during the period of corpus output,using the HSK corpus as the domain.Chapter 3 examines Korean Chinese learners’ cognate phrase acquisition at the beginning of the 21 st century.This chapter also takes the complex dynamic system theory as the entry point and uses the mediated corpus as the domain to analyze the distribution,complexity and accuracy of learners’ use of cognate phrases during the corpus production period.Chapter 4 presents the dynamic changes of Korean Chinese learners’ cognate phrase acquisition.Based on the corpus from two different periods,this chapter provides a comparative analysis of Korean Chinese learners’ acquisition of cognate phrases in four dimensions: acquisition type,acquisition order,acquisition complexity,and acquisition bias,in order to discover their acquisition trends and examine the influence of language development on learners’ acquisition.Chapter 5: Factors influencing Korean Chinese learners’ acquisition of cognate phrases and teaching suggestions.Based on the above analysis,this chapter discusses the main factors influencing Korean Chinese learners’ acquisition of cognate phrases from the dimensions of language,pedagogues and learners,and proposes strategies for teaching cognate phrases on this basis.The third part is the conclusion,which provides a comprehensive summary of the paper and points out the innovations and shortcomings of the existing research.It also briefly explains the research outlook in conjunction with the research findings.
