In this study the authors investigate whether a whole-class educational blog could facilitate culturally relevant instruction and authentic intellectual work in U.S. history. Qualitative data were collected and analyzed that included student comments posted to an educational blog, classroom observations, and follow-up interviews. Based on the analysis, the authors determined four major findings: (a) Students were able to engage in historical analysis while working in the blog environment when it was focused on a single source and included a hard scaffold; (b) when students situated the activities in relevant cultural experiences, they were able to better use their prior knowledge;(c) a variety of affordances related to blogging encouraged and supported students as they completed their work; and (d) the blogging activities were constrained by the limits of students' literacy and historical skills, and the limits of technology.
