Recenzii
Children’s misunderstandings about mathematics ideas stand in their ways to learn mathematics well and effectively in elementary schools. Common Mistakes in Teaching Elementary Math and How to Avoid Them, is the first book, I know, that directly explains teachers’ own misunderstandings about mathematics ideas, how they reproduce them among their students, and more importantly, what they can do to address these issues in their mathematics teaching. Dr. Liu accomplished all the above successfully by engaging readers in experiencing what teachers do and how students react in elementary classrooms using a series of stories. A great book for mathematics teachers, teacher educators, and policy makers.
----Jian Wang, Helen DeVitt Jones Chair in Teacher Education, Texas Tech University
This book appeals to pre-service and elementary teachers who are not math content knowledge experts. Fuchang Liu offers a "quick-fix" for those elementary teachers who are aware that they are struggling as math teachers, and are seeking help.
