Preparation and Practicing for a Teaching Case to the Efficiency Evaluation of Marine Economy Based on the DEAP Software

In order to overcome the shortcoming of emphasis on theory and contempt for practice in traditional mathematics teaching, a teaching case for quantitative study on the efficiency evaluation of marine economy, which combines mathematics, economics and computer software, is given based on the sum-up for the process of designing, preparation and implementation in our own research and practice. It elementary makes up the lack of teaching cases on quantitative study of marine aspects. By summarizing the experience of the case teaching practice, it is suggested in this paper that a successful case should focus on authenticity, universality, opening and pertinence.
