摘　　要：虚拟场馆学习具有不受时空限制的优势,然而在虚拟场馆中学习者容易出现游离现象。对此,文章首先以“人体生命科学”虚拟场馆为实验平台,以东北地区Z大学临床医学专业的2030名大一学生为研究对象,获取了2000名大学生的有效样本数据。之后,文章采用模糊C均值聚类法对学习者进行分类,采用滞后序列分析法转换学习行为序列,采用随机森林算法识别学习者类型和分析行为重要性,得到场馆学习高沉浸型、场馆学习中沉浸型、场馆学习低沉浸型、场馆学习游离型四类学习者,并选出了17种对学习成绩影响较大的学习行为序列。在此基础上,文章设计了虚拟场馆学习行为干预机制并进行了干预效果分析,以期在虚拟场馆教学中为有需要帮扶的低沉浸、游离型场馆学习者提供有效教学干预,从而提升场馆学习者的学习水平和知识掌握程度,并为虚拟场馆在高校的应用提供借鉴。Virtual venue learning has the advantage of not being restricted by time and space,but learners are prone to be free-floating in virtual venues.Therefore,the paper firstly took the virtual venue of“Human Life Science”as the experimental platform,and chose 2030 freshmen majoring in clinical medicine in Z University in northeast China as research subjects,and obtained valid sample data of 2000 university students.After that,the fuzzy C clustering method was employed to classify learners,and the lag sequence analysis was used to transform learning behavior sequences,and random forest algorithm was adopted to recognize the types of learners and analyze the importance of behaviors.Further,four types of learners,namely,high-immersion venue learning,medium-immersion venue learning,low-immersion venue learning,and free-floating venue learning,were obtained,and 17 kinds of learning behavior sequences that had great influence on learning achievement were selected.Based on this,the paper designed an intervention mechanism of learning behaviors in virtual venues and analyzed the intervention effect,in order to provide effective instructional interventions for low-immersion and free-floating learners in virtual venues who needed help in teaching,and further improve the learning level and knowledge mastery of venue learners,and provide reference for the application of virtual venue in colleges and universities.
