This paper aims to explore how to effectively improve the teaching quality of data structures and algorithms under the guidance of the concept of outcome based education (OBE). OBE

as an advanced educational concept

emphasizes on centering on students' learning achievements

clarifying teaching objectives

designing teaching process in reverse

and ensuring the realization of teaching objectives through continuous evaluation and feedback mechanism. Aiming at the core course of computer science

data structure and algorithm

this paper first analyzes its teaching status and challenges

and then constructs the curriculum design framework based on OBE concept. It elaborates the setting of teaching objectives

the organization of teaching content

the innovation of teaching methods

and the evaluation strategy of the achievement of curriculum objectives. Finally

the effectiveness of this model is verified by a practical case

and further optimization suggestions are put forward.
