In this paper, the teaching practice of “Experiment of information display technology” is carried out. The concept of “breakpoint check” is borrowed from the computer program editing and running debugging, and the digital teaching and assessment method of combining virtual and real is proposed by reasonably setting the check breakpoint and teaching resources, and using the rain classroom platform, which is committed to accurately evaluating the students’ knowledge level and ability level. At the same time, through the integration of teachers’ scientific research projects and local enterprise internships, students are encouraged to recreate the knowledge they have learned. The innovation method proposed in this paper is expected to provide experience and reference for the construction of experimental courses.
