Abstract: This paper presents an idea of “engineering orientation, unit experiment, project synthesis” in the experimental course of electronic technology, from the practical significance of new engineering to experimental teaching reform. Then, a multi-layer experimental structure including basic simulation, base verification, extended and comprehensive design experiment is constructed, which forms an experimental teaching system of online-offline blending and basic-advanced integrated teaching. Teaching practice shows that the experimental design integrates experimental teaching and electronic design technology effectively, and highlights the high-order, innovation and challenge of experimental courses. It improves students’ engineering practice and innovation ability, and has important significance for the reform and implementation of experimental teaching under the new situation.
