Higher education reform has become the hot topic in higher education circles and society nearly 10 years. Extroverted and introverted personality traits are inseparable with the growth environment, so we analyzed detailedly the usual psychological change status, the usual personality traits and the reasons of causing personality changes in every schooling year. At present, the cultivation of personality is usually ignored by the teachers of science and engineering colleges, so the free development of personality for students would make them more and more introverted and put their into a vicious cycle. Then we put forward the necessity of the cultivation of extraverted talents, that is, the goal of education is to cultivate the graduates with higher comprehensive quality and strong social adaptation ability. At the end, we discussed the method to cultivate the extraverted talents and emphasized the guidance role and ideas of teacher in the cultivation. The viewpoints and methods put forward by us can give the references for other teachers and readers.
