Abstract: Aiming at the problems and difficulties in the teaching of information theory and coding course,this paper puts forward measures for experimental teaching which was based on the concept of CDIO engineering education.The teaching of a main project runs through the course.The main project can be decomposed into several subprojects,corresponding to a certain course knowledge unit.Each subproject is iteratively implemented in four stages:task conception,program design,task implementation and operation display.It has the characteristics of system integration,teacher guidance and project regression.Practice has proved that the program organically combines theoretical teaching with practical teaching,effectively mobilizing students' subjective initiative,and promoting knowledge acquisition and comprehensive ability improvement.
