Assignments that engage students in inquiry topics of their own choosing contribute to motivation and thus to learning. Very often the topics chosen (particularly by high school students) are considered controversial by school administration, parents, community organizations, and others. This practical book discusses the processes, actions, and policies needed to support and encourage high school students in that type of inquiry. Building trusting relationships over time with administration and the school community will be stressed as a way to build a community of true inquiry in your school and library. Classroom teachers and high school librarians will value the advice and scaffolding techniques presented that will enable their school and high school library to become a safe place for student inquiry into issues of their own choosing- controversial or not. The author draws on her 30-plus years as a high school librarian, deeply concerned with the intellectual freedom of the researchers in her library media center and with offering help and reassurance to those trying to implement school library programs that allow all voices to be heard. Grades 9-12.
