Based on the reform of CDIO educational mode and aimed at deepening the engineering education reform,taking the CDIO experimental class of computer science and technology as an example,the paper puts forward the personnel training program and makes a teaching plan that regards the project as center,changing the traditional teaching mode into "project practice,knowledge refinement and ability development".Make the engineering projects run through four years' teaching activities and strive to enable students to absorb professional knowledge from the perspective of solving practical engineering problems,mastering the engineering thinking methods to improve students' independent ability to analyze,understand and solve problems.
