Book excerpt: This book introduces the concept of Inquiry Graphics, which positions graphics as significant and integrated tools of inquiry in higher education teaching and research. Simply put, the book explores the nuances of thinking and learning with digital images as types of graphics. Although the amount of images in modern life is overwhelming, they have been scarcely explored and understood as integral to concept and knowledge development within higher education practice. This book reflects on why and how digital photographs can be adapted and used in teaching and research contexts. It provides practical examples and applications, as well as theoretical foundations, building on a range of perspectives, such as Peircean triadic sign and approaches to conceptual development. Ultimately, it builds on diverse approaches to make a case for exploring knowledge and analysing concepts and images in a non-dualist and pluralist manner. This unique book will appeal to scholars and students in education studies and educational research, media and communication, and anyone interested in applied semiotics, visual and multimodal pedagogy and learning.
