Abstract: Discrete Mathematics is the core basic course of computer science and technology, which is beneficial to the improvement of students' abstract thinking ability, logical thinking ability and inductive construction ability with the characteristics of strong theory, high abstraction and single assessment method.In view of the above problems , according to the structural model of results-oriented education OBE, which organizes, implements and evaluates education with expected learning output as the center, the idea of carrying out teaching reform in discrete mathematics by using OBE is put forward in this paper. In order to achieve the training objectives and graduation requirements, teaching reform and practice have been carried out from the aspects of teaching content design, teaching method innovation and assessment method improvement, so that students can use the basic principles of discrete mathematics to solve engineering problems, thus realizing the goal of "student-centered and graduate-oriented".

Key words: Discrete mathematics, OBE concept, Teaching reform
