Elevating clinical practice in mathematics education has potential to greatly transform the preparation of effective mathematics teachers. In the current climate of education, clinical practice includes: (1) traditional undergraduates in an educator preparation program, (2) post-baccalaureate individuals who have a degree in another field who are working on their initial teacher license, and (3) teachers in residency programs where full-time teachers are simultaneously earning their license. This book provides cases of all three groups with an emphasis on how clinical practices and course work effectively prepares effective mathematics teachers. This book showcases 51 examples of clinical practice in mathematics education. The cases are organized in chapters with each chapter focused on one of the National Council for Teachers of Mathematics Effective Teaching Practices (NCTM, 2014). Each chapter includes cases aligned to the 8 Teaching Practices with discussion questions and an example clinical practice activity.
