In adult education, algebraic thinking can be a sense-making tool that introduces coherence among mathematical concepts for those who previously have had trouble learning math. Further, a modeling approach to algebra connects mathematics and the real world, demonstrating the usefulness of math to those who have seen it as just an academic…

How do children learn math--and why do some children struggle with it? The answers are in "Number Sense and Number Nonsense," a straightforward, reader-friendly book for education professionals and an invaluable multidisciplinary resource for researchers. More than a first-ever research synthesis, this highly accessible book brings math…

This is a report of an experiment performed to evaluate the effects of the teaching of non-decimal numeration systems in grades four and six.

Tests were given before a teaching session of five to…

This master's thesis was designed to construct a group-administered test of kindergarten and first-grade children's knowledge of the content of "Developing Mathematical Processes" Arithmetic Book I. From a list of behavioral objectives for Book I, 15 were selected as ones whose attainment could be measured in a group paper and pencil test. Eight…
