Douglas Llewellyn focuses on teaching science through an inquiry-based process, showing teachers how to implement inquiry using the three "Rs" of inquiry—restructuring, retooling, and reculturing. Inquire Within helps teachers design inquiries for their students and also provides ready-to-use inquiry lessons. Updates to the Third Edition include:

• Alignment with the new Common Core State Standards and the Next Generation Science Standards


• A central focus on making and defending scientific arguments (i.e. argumentation)


• Guidance on developing the prerequisite attitude and mindset for becoming an inquiry- and argument-based teacher


• How to balance the meaning (the disposition) as well as the mechanics (the how-to) of inquiry and argumentation


• Background on self-directed learning


• Practice in climbing the ladder of professional improvement


• Many new vignettes of inquiry and argument-based activities that integrate language arts with science.


• New sections tie inquiry-based instruction to classroom management, language literacy, the nature of science, multiple intelligence, communication skills, and scientific argumentation.


• The Third Edition is now closely aligned with Teaching High School Science Through Inquiry and Argumentation
