The document summarizes William Doll Jr.'s alternative to the traditional 3 Rs curriculum model called the 4 Rs model. The 4 Rs include richness, recursion, relations, and rigor. Richness refers to curriculum depth with possibilities and lived experiences. Recursion involves reflection and viewing learning as a loop. Relations focuses on connections within and between curricula and using narration and dialogue. Rigor means searching for alternatives and hidden assumptions. The document discusses how each R could be incorporated into classrooms and reflections that the traditional curriculum does not fully align with the 4 Rs approach.
