Research-based learning is newly established in 2000. It advocates for students’ independence in exploring, learning, selecting and determining solutions, and developing students' practical ability. It has become a hot spot in today's classroom teaching. Besides, if teachers apply research-based learning in teaching and leading students to research, a better outcome will come out. The application of research-based learning is also in favor to students’ overall development. I have studied on the necessity and feasibility of applying research-based learning in teaching maths, from concept, background, evolution process, teaching mode and social practice. The research result proves that research-based learning helps students learn knowledge and skills positively, applying what they learn in practice and solve practical problems, develop interest in learning, and moreover be ready for future after graduation.
