Abstract: In response to the problems of weak student autonomy, shallow integration of industry and education, and low integration of technology in traditional statistical data analysis experimental teaching, this article constructs a three-dimensional experimental teaching system that integrates ideological and political education, technology, and industry and education, and is driven by problems, projects, and practices in three dimensions: laboratory, base, and off campus. By optimizing the curriculum structure, innovating teaching models, integrating digital resources, building“dual teacher”teams, and improving evaluation mechanisms, five reform paths have significantly enhanced students' data innovation abilities. Practice has shown that this model effectively solves the problem of the disconnect between experimental teaching and industry demand, providing a reference for cultivating data analysis talents with both morality and talent.

Key words: Experimental teaching reform, “Triple fusion”, “Three dimensional drive”, “Trinity”, Data analysis capability, Cultivation of innovative ability
