The document discusses perspectives on teacher education knowledge bases from Deng & Luke and Habermas. It summarizes that Deng & Luke emphasize the importance of theoretical knowledge and practical experience. They identify three knowledge concepts: disciplinary, practical, and experimental. Habermas identifies three areas of knowledge: analytical, hermeneutic, and critical. He also discusses a theory of communicative and action-oriented model with three knowledge interests. Both perspectives imply teacher education should incorporate experiential learning and critical reflection to develop effective teaching practices.
