The current study examined changes and continuities in how 11 secondary teacher preparation programs and 743 preservice teachers conceptualized the content and sequence of field-based teacher preparation. Although curricula and candidates differed regarding the knowledge each deemed as most relevant for field-based preparation, they largely agreed on the types of learning activities considered as most meaningful for the acquisition of that knowledge base. Possible explanations for these discrepancies and continuities are discussed. (Contains 4 tables.)
