Adolescents' Disciplinary Use of Evidence, Argumentative Strategies, and Organizational Structure in Writing About Historical Controversies

This study considers how adolescents compose historical arguments, and it identifies theoretically grounded predictors of the quality of their essays. Using data from a larger study on the effects of a federally funded Teaching American History grant on student learning, we analyzed students' written responses to document-based questions at the 8th grade (n = 44) and the 11th (n = 47). We report how students use evidence (a hallmark of historical thinking), how students structure their historical arguments, and what kinds of argumentative strategies they use when writing about historical controversies. In general, better writers cite more evidence in their arguments than weaker writers, and older students demonstrate how to situate evidence in ways that are consistent with the discipline. Both the structure of students' arguments and their use of evidence were predictive of the overall quality of their essays. Finally, students' use of argumentation strategies revealed patterns relevant to the historical topic and sources in question, as well as to differences related to writing skill. In our sample, better writers used strategies based on facts and evidence from the documents more so than weaker writers and demonstrated the capacity to contextualize and corroborate evidence in their arguments.
