Stripling, B. K. (2003). Inquiry-Based Learning. Curriculum Connections in the Library. Edited by Stripling, B. K. & Hughes-Hassell, S. Westport, CT: Libraries Unlimited.
Barbara Stripling (of Stripling’s Model of Inquiry fame) authored the first chapter in this book written to connect librarians and educators as collaborators in education. She is a foundational thinker in inquiry-based education, and her words on the approach are a fantastic starting point for anyone approaching the subject.
This chapter is the BEST thing I read in my research for INFO 250: content-rich, based in a history of education theory, deeply inspiring, and full of practical applications that feel manageable. Tracking it down is a bit tricky; I found a used copy of the book on Amazon for $4, and every chapter is gold. SO WORTH IT.
