Laboratory work is so much important in the engineering education. But laboratory work program at most domestic engineering education institutes is still poor and could not have been actively improved and reinforced due to the difficulty in preparing the necessary fund, facilities, professional personnel and so on. The school of mechanical engineering in Pusan National University, sponsored by the national special engineering education project, has poured intensive and strong efforts into improving and strengthening laboratory work program in the courses of education. In this paper, the brief content of the improved laboratory work program and the established system for putting through the program effectively are introduced around the topics such as the integrating laboratory work of mechanical/electronic/computer engineerings, systematic managing and progressive deepening of the laboratory level through the classification of the laboratory works, education system for putting through efficiently the program for a large mass of students and program for encouraging the creativity.
