[Objective] Ideological and political curriculum can integrate professional curriculum with ideological and political education, highlighting the purpose of moral education in collaborative education. However, in the process of practical teaching, there are some problems in the online courses of new engineering, such as insufficient exploration of ideological and political education elements, outdated ideological and political cases, and the lack of evaluation of ideological and political education effect. [Methods] For the classroom ideological and political teaching of Probability Theory and Mathematical Statistics, this paper proposes a curriculum ideological and political teaching method based on ADDIE model. Taking ADDIE model as the core, this method reconstructs the ideological and political module in teaching objectives and teaching content and evaluates the teaching effect from the dimensions of teaching standard, student acceptability, and professional compatibility in online ideological and political teaching cases. [Results] The evaluation results show that this method can stimulate students’ cognitive emotion and improve their acceptance of classroom ideological and political education. [Conclusion] The above methods effectively strengthen students’ consciousness of ideological and political autonomous learning and make a difference in their cognitive degree and emotional cognitive experience with the P value of 0.004 and 0.009 respectively. Students’ acknowledgement on online political and ideological education reaches 78.4%, which is a satisfactory teaching effect.
