Mark Prensky's book of essays is ideal for all K-12 educators. This work illustrates the breadth of his thinking about technology and 21st century learning, and is organized into two sections that address: 1) Rethinking Education and Learning for the 21st Century 2) 21st Century Learning and Technology in the Classroom (instructional methods, curriculum, strategies, use of technology tools such as YouTube, etc.) Some essays, like Blame Our Young? or Use Their Passion!, are very brief (a page or so) and are intended to ask a question or inspire new thinking. Others are more detailed and grounded in research, such as Digital Natives, Digital Immigrants, Part II: Do They Really Think Differently? Each entry is intended to inspire thinking, stimulate conversation, and challenge educators to improve teaching and learning for today's students.
