Teaching Fractions through Situations: A Fundamental Experiment

From the reviews:

 

“This book, intended for teachers, mathematics education researchers, and mathematicians, is about developing and teaching a curriculum for teaching fractions. … the book describes three ‘adventures’ –– the adventure of the researchers while discovering and testing a curriculum for rational number learning, developed using the theory of didactical situations (Chapter 4), the adventure of the teachers implementing that curriculum (Chapter 3), and the adventures of the students experiencing that curriculum (Chapter 2).” (Annie Selden, MAA Reviews, February, 2014)
