At a time when many are preoccupied with big data, this refreshing focus on small data - the focused observations made which can change the way we think about something - is both refreshing and inspiring. Given teaching and learning is about relationships - the relationship between students and their instructor, students and their peers and students and the body of knowledge, which provides the basis of work - subtle changes in these relationships can signal major changes to teaching, learning, technology and assessment. Though this book is not explicitly about learning and higher education, implicitly it is. It is full of stories, practical examples and illustrations of how an observation can lead to the transformation of something as commonplace as Pepsi or Lego. This book will get you thinking.
