Abstract: The "Outcome-based Education(OBE)" is an education concept advocating reverse design, which focuses on what abilities students acquire and what they can do after learning. Starting from students’ graduation criteria, the design of the course of "College English Listening and Speaking" specifies the teaching goals, reconstructs the teaching content and innovates the evaluation approach. By making full use of Tronclass, the university’s online teaching platform, the study aims to establish an O2O blended learning mode and divides the teaching process into three parts: pre-class preview and evaluation, in-class internalization of knowledge and after-class feedback and advancement according to the flipped classroom. In the aspect of students’ assessment, with the help of the mechanism of timely and effective supervision, feedback and evaluation, the mode combines O2O formative evaluation and final summative evaluation to keep improving the teaching quality.

Key words: OBE, College English listening and speaking, Blended learning mode
