The quality of teaching in mechanical engineering greatly depends on the practical application of the fundamental theory taught. During COVID-19, limited access to in-class lectures, practical courses with demonstrator plants, and active student participation forced us to transform our teaching strategy in a limited time. For class sizes of between ~15 and ~700 students, we share our successful transformation strategy in teaching, including different additional interactive formats, supporting materials, and technologies. Furthermore, we present a collection of suitable tools, their functions, advantages, disadvantages, and feedback from three sources to provide profound assessment and adaptation criteria in digital teaching. Using quantitative evaluations of four lectures in automation and information systems over the past five years, we highlight the experience from the students' perspective and evaluate our digital teaching methods compared to well-established in-class formats. This compilation of causes and consequences clarifies the effort involved in achieving the result and discusses the potential of digital teaching or hybrid teaching in engineering.      «
