Kruskal algorithm, as a minimum spanning tree optimization analysis algorithm, has been well used in the field of industrial production to find the optimal parameters. In this study, an interactive teaching platform based on Kruskal algorithm is built based on the ecological aesthetic education theory. Secondly, based on multiple internet of things systems, through the analysis of the problems existing in traditional classroom teaching, combined with the characteristics of ecological aesthetic education, the interactive platform can automatically generate more efficient teaching courses and related methods. Finally, this study verifies the reliability and stability of the above platform through experiments and practices. The experimental results show that the application of the theory and method of ecological aesthetic education in the interactive teaching platform based on Kruskal algorithm achieves the combination of traditional classroom teaching and ecological aesthetic education and gives full play to the main role of students in the classroom.
