Abstract: Ordinary differential equation is a closely integrated discipline of applied mathematics and pure mathematics, it’s a basic course for mathematics majors and one of the teaching module of advanced mathematics for science and engineering compulsory courses. We reformed the teaching mode under the guidance of the OBE concept and the problem existing in the teaching process, based on the new model of the BOPPPS and PAD classroom, this paper showed the design of teaching unit about“the first order linear differential equation and their applications”. On the foundation of effective teaching structure, we led students to take part in learning process and improve the learning effect. In the end, we gathered up the effect and feedback of the teaching reform.

Key words: OBE, BOPPPS, PAD classroom, Blended teaching model, Ordinary differential equation, Practical research
