“新工科”背景下电弧离子镀教学实验设计及混合式教学研究

Study on Experimental Design and Blended Teaching of Arc Ion Plating under the Background of “New Engineering”

摘要: 随着科学的发展与进步，新工科应运而生。新工科的推行直接关乎到了国家未来的战略布局。作为基础技术之一的真空技术已被广泛运用到半导体、电子等新兴领域中，已成为对理工科大学生进行基础教学中不可或缺的一部分。真空阴极电弧离子镀膜实验是一门可以帮助理工科学生认识真空现象、掌握真空组成、了解真空获得、利用真空优势的专业实验。为了能更好地完成实验教学任务，更好地契合新工科背景下的教学实验要求，本文从教学内容、教学方法等方面开展了真空阴极电弧离子镀膜课程教学改革探索。在实验教学方案设计方面，根据新工科教学需求，在教学内容和教学过程中重点细化了电弧离子镀设备的真空系统构成、真空获得。在教学方面，引入了“混合式教学”的教学模式，结合“翻转课堂”理念，变传统的以教师为中心的教学模式为以学生为中心，教师为引导者的工程教学模式，提高了学生课堂的参与度。合理优化了成绩评价机制，拓展了学生的发散思维，提升了学生的创新能力。

Abstract: New engineering is a new concept put forward with the progress of science and technology. The implementation of the new engineering strategy related to the national strategic layout. As one of the basic technologies, vacuum technology has been widely used in emerging fields such as semi-conductors and electronics, and has become an indispensable part of basic teaching for science and engineering students. Arc ion plating experiment is a professional experiment that can help science and engineering students to understand the phenomenon of vacuum, master the composition of vacuum, understand the acquisition of vacuum, and make use of the advantages of vacuum. In order to better complete the experimental teaching task and better meet the requirements of teaching experiments under the background of new engineering, this paper carried out the teaching reform of vacuum negative arc ion plating course from the aspects of teaching content and teaching methods. According to the teaching demand of new engineering, the vacuum system composition and vacuum acquisition of arc ion plating equipment are mainly refined in the teaching content and teaching process. In terms of teaching, combined with the concept of “flipped classroom”, introduced the teaching model of “blended teaching”, changed the traditional teacher-centered teaching model into a student-centered engineering teaching model with teachers as guides, and improved the participation of students in class. It optimizes the achievement evaluation mechanism, expands students’ divergent thinking, and improves students’ innovation ability.
