Second-graders engaged in complex reading, writing, and thinking about Rosa Parks and the Montgomery Bus Boycott. Close readings of secondary and primary sources situated students to discover incongruencies between what is reported within trade-books and what is revealed within historical documents. Scaffolding directed students' scrutiny of secondary sources for historical gaps and of primary sources for historical significance. The scaffolding was differentiated for both text-based and visually oriented primary sources. The assessment--creation of a faux primary source--was discipline-specific and completed through peer- and teacher-led review. Students demonstrated historical literacy, thinking, and argumentation during different phases of this guided inquiry. Teachers and researchers can gain rich, nuanced understandings from examining classroom-based learning.
