内容説明
"Early Fraction Learning" is centrally of interest to students and researchers in mathematics education, since it addresses one of that discipline's most vexing problems: why are fractions so difficult to learn and to teach? The book begins by asking: what is a fraction for a child? From there, it goes on to explore fraction learning of young children in a series of studies that early childhood educators, educational psychologists and cognitive scientists will find very informative and useful.
