“知行合一”是明代思想家王守仁提出的认识论与实践论之间的辩证关系。在现代音乐课堂的实践教育中,“知行合一”观点的课堂渗透同样能引发教师对音乐教育的目的、途径的思考。本文通过对职业中专学校中音乐教学课堂教育中其观点的运用,反驳了某些学者认为“知先于行”、“知重于行”等观点的误区。 “Unity of knowledge and practice ” is the dialectical relationship between epistemology and practice put forward by the Ming Dynasty thinker Wang Shouren. In the practice education of modern music classroom, the classroom penetration of “knowledge and practice” can also lead teachers to think about the purpose and approach of music education. This article refutes the misunderstandings that some scholars think of “prior knowledge” and “emphasis on knowledge” through the application of its viewpoint in the classroom teaching of music education in vocational technical secondary schools.
