Abstract: [Purposes]Addressing the “three highs and three difficulties”(high cost,high difficulty,high risk; difficult implementation,difficult observation,difficult reproduction)in practical teaching for surveying and mapping majors,as well as the inadequacy of traditional blended learning in meeting students' online skill acquisition needs,this study explores a novel teaching model tailored to cultivating high-quality technical talents through the deep integration of virtual simulation technology with education.[Methods]Firstly,the core connotation of the “dual-blended”practical teaching model is explicitly proposed,namely the integration of virtual and real environments and the blending of online and offline approaches.Secondly,the content framework of this model is designed from three dimensions—resources,activities,and evaluation—while the teaching process is restructured into three stages: “pre-learning,mid-term reinforcement,and post-transfer.”Finally,the model's feasibility and effectiveness are validated through teaching practice.[Findings]The results demonstrate that this model effectively overcomes the bottleneck of online practical teaching,establishes a learning environment supporting students' repeated skill training,facilitates the systematic integration of their knowledge and skill systems,and achieves the organic unity of three-dimensional teaching objectives: knowledge acquisition,skill application,and professional competence.[Conclusions] As both an inheritance and innovation of traditional blended learning,this model provides an operable theoretical framework and practical pathway for cultivating technical talents in higher education institutions.
