**This open access book is the product of ICMI Study 22 Task Design in
Mathematics Education. The study offers a state-of-the-art summary of
relevant research and goes beyond that to develop new insights and new
areas of knowledge and study about task design. The authors represent a
wide range of countries and cultures and are leading researchers,
teachers and designers. In particular, the authors develop explicit
understandings of the opportunities and difficulties involved in
designing and implementing tasks and of the interfaces between the
teaching, researching and designing roles - recognising that these might
be undertaken by the same person or by completely separate teams. Tasks
generate the activity through which learners meet mathematical concepts,
ideas, strategies and learn to use and develop mathematical thinking and
modes of enquiry. Teaching includes the selection, modification, design,
sequencing, installation, observation and evaluation of tasks. The book
illustrates how task design is core to effective teaching, whether the
task is a complex, extended, investigation or a small part of a lesson;
whether it is part of a curriculum system, such as a textbook, or
promotes free standing activity; whether the task comes from published
source or is devised by the teacher or the student.
