Abstract: Using the concept of "freezing point depression of dilute solutions" as a case study, this paper explores and implements a multidimensional interactive teaching model integrating "theory-experiment-ideological education-professional innovation." Through a blended online-offline approach incorporating problem-based/case-based learning, flipped classrooms, and group tasks, the model successfully combines theoretical instruction, experimental reinforcement, ideological education, and extracurricular expansion. The results demonstrate that this approach effectively enhances student engagement, fosters innovative thinking, and develops problem-solving skills while achieving comprehensive educational objectives.

Key words: Freezing point, Teaching, Ideological and political education, Innovate
