AbstractTo cultivate applied talents with innovativeconsciousness and practical hands-on ability,the application foundation of the three-level teaching modelof“cognition,practical training,hands-onoperation”introducedin the Bioinformatics course of Plant Protection major was analyzed,and carriedout teaching reform practice.Theapplication foundation includes three levels.Atthecognition level,students mainlylearn the basic theoretical knowledge to cultivatetheir interestin learning;；atthepractical training level,cultivatepracticalabilities throughcaseanalysis, simulated data operations,and other methods;atthe hands-on level,cultivate the ability to solve problems through innovative experiments，scientificresearch projects.Intermsof teachingreformpractice,integratingprofesional theoretical knowledge atthecognitivelevel,constructing interdisciplinary knowledge systems,and innovatingteaching methods；strengthenpractical skilsatthepractical training level，design training projectswith plantprotection characteristics,improve training facilitiesand teaching staff；promote interdisciplinary innovationpracticesatthe hands-onoperation level,facilitate theintegrationof scientificresearch projectswith learning,andparticipate in interdisciplinary competitionactivities.Inaddition,adopting diversified evaluation methods，emphasizingoutcome based evaluation,introducing studentself-evaluationand peer evaluation,and establishing acomprehensive evaluation file. The practical results shows that the teaching reform has produced good results,with 90% of students proficiently mastering the practical operation skills ofcommonlyused tols in thecourse,such as sequence alignment,evolutionary tree construction,andtheuseofbiologicaldatabases;a totalof16 studentteams have apliedandbeenapproved for the university level innovation training program basedontheir course learning achievements.Thisarticle provides references forcultivating more high qualityand information-based inteligent plant protection talents.
