The invention discloses an adaptive retrieval enhanced teaching case generation method. Firstly, a
knowledge graph strictly aligned with a subject
system is constructed, unification is completed in a subject category and case
knowledge unit level, and six types of elements including teaching objectives, ideological and political focuses, three forms, exercises, professional items and incentive wakeup are further standardized. Secondly, analyzing teacher requirements by the
case identification model, carrying out multi-path retrieval, evaluating the correlation and calculation overhead of candidate paths, and determining an optimal reference path; and then,
rewriting the triple in the candidate path into a
natural language, generating a corresponding case fragment according to an element driving generation model, implementing quality evaluation based on integrity,
clarity, consistency and compatibility, and finally synthesizing a teaching case with a complete structure. The method effectively inhibits model illusion and redundancy generation, significantly improves content accuracy and coherence, and is suitable for application scenarios such as course preparation and intelligent teaching assistance.
