Drawing on experiences in his social studies classroom, Houman Harouni evaluates both the challenges and possibilities of helping high school students develop critical research skills. The author describes how he used Wikipedia to design classroom activities that address issues of authorship, neutrality, and reliability in information gathering. The online encyclopedia is often lamented by teachers, scholars, and librarians, but its widespread use necessitates a new approach to teaching research. In describing the experience, Harouni concludes that teaching research skills in the contemporary context requires ongoing observations of the research strategies and practices students already employ as well as the active engagement of student interest and background knowledge.
