Research on the Construction and Application of International Chinese Teachers' Professional Competence Evaluation Model Based on Multimodal Data Fusion

Conducting professional competency evaluation of international Chinese language teachers is an important measure to promote the standardization of the international Chinese language teaching staff, and strengthen the construction of the International Chinese Language Education standard system. With the digital development of the International Chinese Language Education, new generation information technologies have provided new paths for the professional competency evaluation of this teachers. According to "Professional Competence Standards for International Chinese Language Teachers", this paper divides the relevant multimodal data into basic information data layer, environmental situation data layer and behavior characteristic data layer, and constructs the evaluation model from four levels: multimodal data collection, data preprocessing, fusion calculation and analytical applications. Research has shown that this evaluation model helps Chinese teachers continuously improve their ability profile and enhance their professional competence in a continuous, contextualized, and dynamic evaluation process. Based on the evaluation results, it helps to drive evidence-based decision-making in education management, establishing intelligent intervention mechanisms, and achieving personalized resource recommendations, which can serve teachers' development, providing a good teacher guarantee for the high-quality and connotative development of international Chinese language education.
