Twenty-five first-year preservice teachers attending a university in the Midwest of the United States of America participated in a whole-class-setting study aimed at investigating their knowledge of how they made sense of fraction concepts and operations, and how the development of this knowledge was facilitated during a mathematics education…

The ability for students to understand numbers and other mathematical symbols is a crucial part of success in mathematics. Accordingly, it is important for researchers to understand the nature of symbolic number processing -- the connections between a symbol or collection of symbols that convey numerical information (e.g., Arabic digits,…

When counting, the final word used to tag the final item in a set represents the cardinality, or total number, of the set. Understanding of this concept serves as a foundation for children's basic mathematical skills, such as arithmetic. However, little is known about how variations in the early learning environment affect children's understanding…

Research on preservice teacher learning has often focused on coursework and course related field experiences, and not as much on the learning that takes place during student teaching field experiences. Since preservice student teachers are engaged with children on a daily basis, attention to their own students' thinking should be viewed as a means…
