Abstract: According to relevant requirements of engineering accreditation, the teaching mode of digital electronic experiments course is explored with project-based teaching as the main line to improve engineering ability. The course is carried out on a small digital system decomposed into several unit circuits. Each unit circuit is set as experimental unit containing the key points of digital electronic technique course. Finally, the digital system is completed by assembling and adjusting all experimental units. This teaching mode helps students improve their ability of constructing digital system to carry out experimental research, improve their ability of analyzing experimental data and writing experimental reports, and preliminarily train students' ability to solve complex engineering problems.

Key words: Digital electronic technique experiment, Project-based teaching, Experimental teaching reform, Engineering accreditation
