一种模拟职业技能鉴定的云班课随机组卷

A Random Test Paper of Cloud Classs Based on Simulated Vocational Skills Appraisal

大量的模拟测试训练是提高职业技能鉴定理论考试成绩的必要手段,基于智能手机的云班课APP已得到广泛应用,但其组卷需从题库手工选题,知识点的选取难以均衡分布,甚至重复抽取,通过分析题库资源构建的标准格式,将题库按科目分类整理,以Visual LISP语言为开发工具,应用Active交互技术导入Excel题库,设计无重复的随机抽取函数,基于该函数,分别从分类题库资源随机抽题,实现了高效均衡无重复的随机组卷。实践表明,云班课的随机组卷测验的应用,提高了学生的学习积极性,大幅提高了考试通过率。

A large number of simulated test training is the necessary means to improve the theoretical test re-sults of vocational skills appraisal.App based on smart phones has been widely used in cloud class.However,the test papers need to be manually selected from the question bank,and the selection of knowledge points is difficult to balance distribution,even repeated extraction,etc.By analyzing the standard format of question bank resources construction,the paper can be divided into three parts:this paper classifies the item bank according to the subject,uses Visual LISP language as the development tool,applies Active interactive technology to import Excel item bank,designs non-repetitive random extraction function,and based on this function,randomly extracts questions from the resource of the item bank,realizes efficient and balanced non-repetitive random test paper formation.Practice shows that the application of random test paper in cloud class has improved students’learning en-thusiasm and greatly improved the passing rate of the examination.
