Three-dimensional Interpretation of the "Open Classroom" of Practice Education: Historical Logic,Value Implication and Practice Approach

The "open classroom" of practical education serves as a vital bridge connecting the "educational field" with the "social field" in building a strong education nation in the new era. Grounded in historical logic and structured through a "three-dimensional framework", this study systematically traces the evolution of practice education from ancient "unity of knowledge and action" to contemporary "holistic education", revealing its historical progression from instrumental rationality to value rationality and ultimately ecological rationality. Focusing on the contemporary context and integrating the goals of building a strong education nation with digital transformation, it elucidates the groundbreaking advancements of the "open classroom" in fostering collaborative education stakeholders, integrating domains, and empowering through technology. Addressing practical needs, the research constructs implementation pathways through three dimensions: individual development, educational innovation, and social service. This study aims to provide theoretical references and actionable guidance for optimizing the practice education system, helping resolve current challenges in its implementation.
