The aim of ideological and political education is to guide students to set up correct values, understand and reform the world. Based on the characteristics of advanced mathematics course, this paper conducts teaching practice from three aspects: hierarchical teaching, integrated teaching and vivid teaching. With philosophical concepts as the “connotation” and mathematical analysis methods as the “form”, we integrate elements such as philosophy, current affairs, and outlook on life in ideological and political education into the curriculum of higher mathematics. Moreover, based on the knowledge structure of advanced mathematics, this paper introduces ideological and political elements based on chapters, completes the overall ideological and political curriculum design of advanced mathematics, and provides references for the teaching practice of advanced mathematics teachers.展开更多

The quality of practical teaching in data mining courses is an important aspect of cultivating professional competence. In order to further improve the quality of practical teaching in the course, this article will discuss the “dual classroom” teaching model of parallel company classroom and campus classroom. In the new model, the teaching content, instructors, academic evaluation, and teaching environment of practical teaching have been reformed. The questionnaire survey shows that: (1) The company classroom not only allows students to experience the real scenarios of company data mining, but also helps them understand the principles of algorithms better. (2) Students believe that online company classrooms are not only time-saving but also flexible. Company classroom is a useful supplement to campus classrooms. (3) Practical teaching under the “dual classroom” model receives positive feedback from students. Students are willing to recommend the company classroom to their classmates and friends.展开更多
