Abstract： This paper proposes a localized inteligent teaching system based on LangChain and DeepSeek-7B-R1， aiming tosolve thechalengesofasynchronous programmingcomprehensionandDOMoperationerordetectionin JavaScript and jQuery teaching.Toaddresstheconflictsamong semanticunderstanding，privacysecurityandhardwarerequirements in traditional solutions，this paper designs a dual-engine architecture （rule pre-screening + LLMfine-tuning） thatintegratesdynamic ASTparsing andan enhancedRAGretrieval mechanism，constructinga teaching Knowledge Graphcovering 57typesof typical errors.Experiments demonstrate that thesystemachieves anaverage response time of 2.8 seconds on NVIDIA RTX 3060 device，and the teaching suggestion accuracy reaching 91 . 2 % ，witha 4 3 . 7 % improvement over conventionalLSTM approaches. Deployment in corporate internal training scenarios verifes its capabilityto enhance learner problem-solving eficiency by 41 % whilereducingteachermanual intervention by 76 % .Thisresearch provides the firsthigh-precisionand localized intelligent teaching framework supporting consumer-grade hardware for the programming education field， with open-source core components to lower development barriers.
