From the book reviews: "It is a comprehensive and well-written book with synergies across the areas of research and curriculum development ... . It therefore holds implications for researchers and practitioners at every grade level. ... A book of this breadth has a place on every researcher's shelf. ... For those considering carrying out research about student conceptions of matter, chemical structure or bonding, the chapters in this book covering these topics are exceedingly well referenced and provide new directions in research." (Marcy H. Towns, Studies in Science Education, July, 2014) "This substantial book, organised in six sections, offers 21 chapters emerging from a 2010 symposium held in Athens, Greece ... . any chemistry teacher digging into this book will find something of value to help them help their students to more clearly 'see' and understand the concept of matter." (Vanessa Kind, Education in Chemistry, March, 2014)
