Abstract: Based on the training plan of Science and engineering specialty, this paper collects, analyzes and explains the teaching process and results by means of questionnaire, to establish the teaching evaluation mechanism of probability theory and mathematical statistics based on OBE (achievement-oriented) educational concept. Non-rich probability theory and mathematical statistics teaching evaluation mechanism. To some extent, it solves the problem of monotonous method and single subject in teaching evaluation mechanism of probability theory and mathematical statistics.

Key words: OBE educational concept, Probability theory and mathematical statistics, College public mathematics course, Learning status, Teaching evaluation mechanism, Teaching evaluation mechanism design
