“electric control and PLC” is a specified course with much practicability. Its teaching content comes from producing practice. As the application field is extending, the content of courseware becomes more and more abundant. Therefore, to emphasize practical teaching and to reform the course generally has been imperative under the situation.in this paper, a new system of PLC Three-dimensional Teaching was adopt. The experience and methods in terms of making proper teaching objectives, optimizing teaching content, improving teaching manner, stressing practical teaching and training practical ability, were proposed in this paper, through experimental teaching, course design, production practice and integrated training, the students’ engineering practice ability and creative ability have been improved dramatically. this did a significative exploration on improving teaching level and culturing engineering technology persons with high diathesis.
