Labor education plays a key role in the development of the practical skills and professional qualifications of students and can help shape good citizens as well. This paper employs the structural equation model technique to analyze the existing situation regarding the cultivation of professional ethics and practical skills among students of a specific educational institution. On the basis of empirical data, the structural equation model is built connecting the cultivation of professional ethics with that of practical skills. In the proposed model, the directional relations and specific forms of manifestation depending on geometric thinking are quantified. As a result of empirical studies, it becomes clear that the impact of labor education on the development of the students’ professional ethics and practical skills is significant. Therefore, educational institutions need to theoretically understand the importance of labor education, to improve the relevant curriculum and to introduce a greater proportion of practical training with new content and methods. Moreover, it is recommended that labor education be promoted through the creation of labor culture in the campus environment.
