Despite concerted efforts to improve educational practices through reform, classroom implementation remains a persistent challenge. This theoretical article draws on recent work in cultural sociology to offer a fresh perspective on this problem. It introduces a framework that differentiates between declarative, procedural, and public forms of culture, highlighting their unique mechanisms of internalization and enactment. This multidimensional understanding of culture reveals the cognitive challenges inherent in translating reform principles into classroom practices. More specifically, the article contends that the common assumptions of convertibility and transferability between these forms of culture underlie the limited success of many reform initiatives. By attending to the cognitive dimensions of cultural dynamics, the proposed framework opens new avenues for understanding and addressing the difficulties of educational change. This article concluded with an agenda for future research to test and refine the framework.
