The Dynamic Development Of Central Asian Advanced Chinese Proficiency Learner Writing Vocabulary

Dynamic system theory pays attention to the differences of individuals and the interaction of internal components.It regards the development of language as a changing adaptive system,which provides excellent paradigms and methods for analyzing complex second language systems.Based on the theory of dynamic system,this paper analyzes and sorts out the research status of the output of writing vocabulary,and finally determines that the senior Chinese level of Chinese students majoring in Chinese international education of the school of international cultural exchange of Northwest Normal University is the research object,and compared with the Chinese Level Standard of International Chinese Education.Accurate,investigate the compositions of four advanced Chinese proficiency learners in central Asia for one semester,supplemented by retrospective interviews and teacher interviews,focusing on the similarities and differences in the use of vocabulary by four advanced Chinese-level learners in central Asia in a semester;the change path of vocabulary complexity,vocabulary accuracy and vocabulary diversity;and central Asia three questions about vocabulary teaching for advanced Chinese proficiency learners.On the basis of observing and analyzing each dimension of learner’s vocabulary complexity,vocabulary accuracy and vocabulary diversity,with the help of mobile extremum graphs,Monte Carlo simulation and other tools are used to find out the key micro-changes of learners in the stage transition,judge the correlation and influence of dimensions,and comprehensively describe learner’s writing words.The different development paths of the sink and the relationship between various dimensions.First,advanced Chinese-level learners in central Asia show nonlinear and individual differences in vocabulary learning and use,indicating that the learner’s vocabulary system is still in a certain change and has not been fully stable,and the vocabulary development system will still be very volatile,which will show a strong nonLinear development characteristics and individual differences;they also show certain commonalities,such as the phenomenon of vocabulary plateau in vocabulary learning and use;lexical diversity develops significantly with the growth of learning time,and class symbols increase significantly;a more accurate understanding of vocabulary meaning has a positive direction for learner’s vocabulary complexity and accuracy.Second,learners’ vocabulary complexity,vocabulary accuracy and vocabulary diversity change irregularly in a single dimension.The correlation between different dimensions is mainly based on the competition of vocabulary accuracy and complexity and diversity,which produces rich changes over time and presents dynamic complexity.Based on the above conclusions,it is proposed to pay attention to learner differences and carry out differentiated personalized vocabulary teaching;attach importance to vocabulary meaning understanding and build a combined aggregated vocabulary knowledge network;pay attention to the development of vocabulary dimensions and highlight the advantages of supportive and relevant vocabulary learning.
