The geriatrics department of Zhongnan Hospital covers all subspecialties of internal medicine with six separated wards

so it is difficult to manage and teach the students who participate in standardized training for resident physicians. In the residents' standardized training of geriatrics department

the interactive support platform named micro-teaching assistant was applied to carry out teaching activities such as classroom check-in

classroom testing and classroom discussion of teaching rounds and small lectures. It not only effectively manages the teaching order

but also improves students' enthusiasm and autonomy by encouraging them to participate in classroom interaction actively. The case analysis quiz and interactive discussion have a good effect on consolidating and deepening the students' professional knowledge

and improving the ability of clinical analysis and problem solving. The attendance rates

class discussion and test scores were recorded in a real and objective way

so that teachers can observe the whole process of students' learning and then make a formative assessment. At the same time

teachers are urged to adjust the teaching contents and progress in time

so as to achieve the goal of promoting teaching and learning mutually.
