  摘 要:“虚拟化技术”课程是云计算技术应用专业核心课程。针对目前课程内容与岗位需求脱节、课堂教学单向灌输、考核方式单一等问题,从教学内容、教学模式和考核机制等方面开展了课程教学改革探索,提出了适合“虚拟化技术”课程的新方法:基于工作岗位、1+X证书的内容以及云计算大赛的内容重构了课程内容;提出了基于三阶段的线上与线下相结合的混合式教学模式;构建了过程性评价和总结性评价相结合的考核方法。该教学改革实践证明,提出的方法激发了学生学习的兴趣,提高了学生的学习能力,改进了教学质量,取得了良好的教学效果,对人才培养具有参考价值。

  Abstract: “Virtualization technology” course is the core course of cloud computing technology application major. In view of the current problems such as the disconnection between the course content and the job demand, one-way indoctrination of classroom teaching, and single assessment method, the course teaching reform is explored from the aspects of teaching content, teaching mode, and assessment mechanism, and new methods suitable for the “virtualization technology” course is proposed: the course content is reconstructed based on the job position, the content of 1+X certificates, and the content of cloud computing competition; a blended teaching mode based on the combination of online and offline teaching in three stages is proposed; an assessment method combining process evaluation and summary evaluation is constructed. The teaching reform practice has proved that the proposed method has stimulated students’ interest in learning, improved students’ learning ability, improved teaching quality, achieved good teaching results, and has reference value for talent training.
  Keywords: teaching reform; virtualization technology; blended teaching; teaching evaluation

  近年恚随着云计算、大数据、人工智能、区块链等新一代信息技术逐渐应用到课堂教学中,混合式教学在国内外许多高校中蓬勃开展和广泛应用。为了提升混合式教学的教学质量,很多学者在教学理论、教学模式,教学方法等方面对混合式教学进行了研究[1-3]。混合式教学模式也应用到了实际教学中,例如,文献[4]针对无机及分析化学课程为例,提出了以学生为中心,教师为主导的三位一体的混合式教学方法;文献[5]以高校的工业微生物学课程为例,基于超星泛雅网络教学平台,建立集网络课堂和数字化资源为一体的智能教学体系;文献[6]以“船舶锅炉水位控制综合实验”课程教学为例,基于“翻转课堂+雨课堂+MOOC”的教学模式,开展了教学内容、教学设计、考核机制等方面的研究。这些研究成果不仅值得学习和借鉴,而且成为本文研究的理论基础。
  1 课程基本情况
  “虚拟化技术”是云计算技术应用专业核心课程,该课内容包括服务器管理、网络、存储等方面的知识,范围比较广,理论知识难,学生不易理解;在实操过程中,软件对硬件资源要求高,操作复杂,学生不易掌握。授课方式以教师为中心,教师讲授为主,教学过程中学生参与度不高,课堂气氛沉闷,课堂纪律差,缺少活力,学生主动思考问题的积极性不高,逐渐对该课程的学习失去兴趣。在对学生考核方面,以考试分数为主,经常出现“考前背”的情况,没有达到对学生考核的目的。
