Congratulations to Tasos, Di and Rebecca on the publication of their book Researching and Using Progressions (Trajectories) in Mathematics Education.
This book, edited by Tasos, Di and Rebecca, has its origins in independent but parallel work in Australia and the United States over the last 10 to 15 years. It was prompted by a research seminar at the 2017 PME Conference in Singapore that brought the contributors to this volume together to consider the development and use of evidence-based learning progressions/trajectories in mathematics education, their basis in theory, their focus and scale, and the methods used to identify and validate them. In this volume they elaborate on their work to consider what is meant by learning progressions/trajectories and explore a range of issues associated with their development, implementation, evaluation, and on-going review. Implications for curriculum design and future research in this field are also considered.
A number of distinguished academics from the US and Australia have contributed research chapters.
This book is Volume 3 of the BRILL/SENSE Series Global Education in the 21st Century edited by Tasos Barkatsas.
Congratulations to all involved.
