It is proposed by Ministry of Education to have at least one-year internship in factory during four-year college education and training of excellent engineers, so for most pilot majors, the fourth school year is set as internship period. However it has been proved that learning of more theoretical courses that are supposed to be finished in advance has put much burden on students; meanwhile, long-time internship in welding workshop would also bring safety concerns. All of these factors make it difficult to proceed well. For the current problems we have encountered during students' internship, cultivating mode of outstanding engineers, aiming at cooperative improvement both in theoretical and practical ability, has been brought out and implemented based on the cognitive development of human. It is indicates that students' learning initiative is being mobilized and their ability is also being improved greatly through the cooperative improvement mode. KEYWORD: Excellent engineers; internship; theoretical knowledge; practice ability; coordinate improvement
