"We the People . . . Project Citizen," an instructional product, involves students in the selection and investigation of important public issues in their community and thus engages students in learning experiences designed to affect positively their civic development, which involves three basic components of democratic citizenship: (1) civic knowledge, (2) civic skills, and (3) civic dispositions.
