 The science and engineering courses include lecture and laboratory education, either in the same course(s) or in separate courses.However, some professors and educators believe that engineering programs should change to focus more on professional engineering practice, and engineering courses should be taught more by professional engineering practitioners and not by engineering researchers.Many engineering degree programs admit students directly as first-year; for those who don't students by the end of the first or second year as an engineering student should decide what specialization they would like to study.
