1、 Research background

It was introduced that the COVID-19 led to the change of international Chinese education from offline to online, and online teaching became the new normal. Analyzed the characteristics, modes, and methods of online teaching, and discussed the difficulties and problems that exist in teaching. It is pointed out that overseas international students face problems such as being disconnected from the target language environment, inconvenient communication, and difficulties in obtaining information, and urgently need learning resources and tool support. There is a shortage of Chinese language learning dictionary resources, and resource construction work urgently needs to be carried out. The existing research lacks real-time data support for building Chinese learning dictionary resources that are suitable for new teaching models and cater to the needs and usage of international students at different levels and grades. This study aims to investigate the use of Chinese language learning dictionaries by international students in the context of online teaching, analyze the impact of online teaching on dictionary usage, and explore how to meet the dictionary usage needs of international students in the new situation.

2、 Survey Design and Implementation

This article introduces the survey design and implementation of the usage and demand of Chinese language learning dictionaries for international students in the online teaching environment. The survey is divided into two stages: questionnaire survey and interview. The questionnaire includes three parts: basic information, online learning and dictionary usage, and methods for coping with learning difficulties. Six universities in Northeast, North, and Southwest China were selected for convenience sampling, and a total of 198 valid questionnaires were received. The survey mainly targets students from Asian countries who have studied Chinese for more than one year. 87.38% of them have HSK level 3 or above, and their educational backgrounds are mainly undergraduate and graduate. After preliminary statistical analysis, a one-on-one structured interview was conducted with 12 international students, focusing on the impact of online teaching on dictionary use after the COVID-19 epidemic.

3、 Analysis of survey results

The situation and needs of international students using Chinese language learning dictionaries in the online teaching environment were analyzed through investigation and interviews. The characteristics discovered include: changes in teaching methods leading to an increase in the frequency of dictionary usage; There is a stratification in the dictionary usage needs of students at different levels of education and grades; Student dictionary query behavior exhibits strategic characteristics. Specifically, international students face many difficulties in online learning, such as network issues, lack of peer learning, and lack of concentration, which leads them to use dictionaries more frequently. The process evaluation indicators added by teachers have indirectly increased the frequency of dictionary usage. Students can easily access dictionaries anytime during online teaching.

4、 Conclusion and Suggestions

Research has found that online teaching has an impact on the use of Chinese language learning dictionaries by international students. Suggestions have been put forward to optimize the allocation of dictionary resources, strengthen the research on dictionary coding functions, and construct a dictionary resource matrix. Emphasizing that educated students become the main force of international students studying in China, it is necessary to pay attention to their "language learning+professional learning" needs, improve the efficiency of dictionary usage, develop dictionary tools with unique and specialized functions, and meet the needs of different learners.
