On the Application and Value Reinvention of AI Technology in Composition Instruction: A Case Study of Teaching the Third-Grade Composition “My Plant Friend”

Composition instruction is the core component of language teaching, yet it has long been hampered by challenges such as imprecise guidance, delayed feedback, and difficulty in personalization. The maturation of artificial intelligence (AI) technology offers a novel solution to overcome these obstacles. This paper aims to systematically organize and specifically introduce AI technologies applicable to composition instruction (such as NLP and AES) along with their corresponding software. It further analyzes practical implementation methods and implementation pathways through a teaching case study of the lesson “My Plant Friend” from the third-grade lower semester curriculum. Practice demonstrates that AI technology—through scenario creation, targeted recommendations, real-time assistance, and data-driven assessment—can effectively establish a new paradigm for efficient and precise composition instruction, providing educators with practical modern teaching tools.
