The document provides an overview of a presentation by Deborah Kozdras on using artifacts in trace-based cases for teaching history. It discusses using artifacts as traces of the past to spark questions from students and have them investigate the context around when, where, who, how, and why regarding the artifact. Examples are provided of using an earthenware sculpture of a horse from China to discuss the importance of horses to the Han Dynasty and the development of the Silk Road. Guiding questions are suggested for how to structure an investigation and argument around an artifact. Resources like timelines, textbooks, poems, and articles are recommended to supplement the students' research.
