在工业数字化技术迅速发展、自动化水平不断提升的驱动下,《热工测量仪表》课程存在传统教材内容滞后、课堂教学模式单一等问题。为了提升学生培养质量,本文通过分析热工测量仪表课程的教学痛点,提出了新工科数字化背景下的教学改革措施,构建“数字教材 + 研讨式课堂”新型授课模式,设计了“三维协同育人”的教学思路,通过网络平台编写数字化教材,实现课程内容的动态更新,并在线下课堂开展热工测量仪表新技术研讨,进行教与学的深度互动。形成“线上知识构建–线下实践应用”的教学闭环,为新工科数字化创新教学模式提供一定借鉴。Driven by the rapid development of industrial digital technology and the continuous improvement of automation level, there are some problems in the course of “Thermal Measurement Instrument”, such as the lag of traditional teaching materials and the single classroom teaching mode. In order to improve the quality of students’ training, this paper analyzes the teaching pain points of the course of thermal measurement instrument, puts forward the teaching reform measures under the background of new engineering digitalization, constructs a new teaching mode of “digital teaching material + seminar classroom”, designs the teaching idea of “three-dimensional collaborative education”, compiles digital teaching materials through the network platform, realizes the dynamic update of the course content and carries out the new technical discussion of thermal measurement instrument in the offline classroom and the deep interaction between teaching and learning. The teaching closed loop of “online knowledge construction - offline practical application” is formed, which provides some reference for the digital innovation teaching mode of new engineering.
