Abstract: "Pictorial turn" has led sensitive qualitative researchers to consider images as qualitative research data, on the basis of which image interpretation methods have gradually developed. The visual attributes of the teaching space and the imaging method have natural relevance. Symbolic symbols, metaphorical forms and facts in the teaching space express the "tacit knowledge" and "conventions" in education. The interpretation process from the explicit "facts" and"forms" to "tacit knowledge" is Erwin Panofsky's translation process from Iconography to Iconology. The study used Panofsky's Iconology method to analyze the teaching space pictures of D primary school from 1988 to 2018. In the pre-iconography layer, D primary school is gradually changing in terms of teaching media, space rights, student learning methods and teacher roles. In the iconography layer, teachers' acceptance and internalization of modern educational concepts, the importance of school institutions to the principles of intuitive teaching, the pursuit of educational modernization and the practice of the new curriculum reform concepts have contributed to the above changes. In the iconology layer, the modern information technology revolution, the modern education ideological trend baptism and the education funding policy in China are the deep social reasons for the transformation of the teaching space.
