Starting from the network nature of the Chinese vocabulary system, we can construct various vocabulary networks. Teaching through the activation relationships between each node can help students restructure their mental lexicon and master more vocabulary within the same class time. The network-based construction teaching of Chinese psychological lexicon for international students based on the perspective of systems theory, represents an optimized teaching model within the existing curriculum framework. This approach emphasizes the increase of the proportion of vocabulary teaching in Chinese language classes. By integrating vocabulary network construction closely with skilled-based course teaching through centralized vocabulary instruction, it seamlessly blends into various stages of classroom introduction, lectures, practice, review, and assessment.
