Through the integration of technology, innovation and entrepreneurship education and the innovation of teaching methods, it aims to promote a fundamental change in teaching mode. In response to the challenges posed by the difficulties of technological integration, the transformation of educational philosophies, and the fusion of innovation and entrepreneurship, the paper suggests the construction of a smart education ecosystem. It advocates for leading changes in educational concepts and management mechanisms, deepening curriculum integration, and strengthening policy and resource support. Furthermore, it explores innovative pathways and strategies for addressing these challenges through diversified mixed teaching models.展开更多
