Exploring the paths of ideological and political education in the recommendation system course can help to cultivate students’ correct values and create a healthy social information environment. This paper is based on the task of cultivating virtue and nurturing people, and explores the corresponding paths of ideological and political education through analyzing the teaching problems and the teaching examples in the recommendation system course. Starting from the impact of outliers in collaborative filtering and the possibility of lying in explicit ratings, as well as the “cold start” Matthew effect and the user inertia in explicit ratings, two problem ideological and political paths — value orientation and moral literacy are respectively condensed. The study explores two example ideological and political paths — the Infiltration and Nurturing style and the Clarification-Actualization style, and provides the corresponding examples. This paper aims to provide a certain reference for cultivating high-quality talents with both morality and ability, and promote the ideological and political construction of recommendation system courses.
