Rizkianto, Ilham; Zulkardi; Darmawijaya – Indonesian Mathematical Society Journal on Mathematics Education, 2013
Previous studies have provided that when learning shapes for the first time, young children tend to use the prototype as the reference point for comparisons, but often fail when doing so since they do not yet think about the defining attributes or the geometric properties of the shapes. Most of the time, elementary students learn geometric…

Kang, Helen W.; Zentall, Sydney S. – Educational Technology Research and Development, 2011
This study hypothesized that increased intensity of graphic information, presented in computer-generated instruction, could be differentially beneficial for students with hyperactivity and inattention by improving their ability to sustain attention and hold information in-mind. To this purpose, 18 2nd-4th grade students, recruited from general…

Anderson, Nancy Canavan; Gavin, M. Katherine; Dailey, Judith; Stone, Walter; Vuolo, Janice – National Council of Teachers of Mathematics, 2005
This book follows students' natural progression from measuring with informal or nonstandard units to using standard units to measure such attributes as length, weight, angle, and temperature. Activities extend students' learning to the measurement of two- and three-dimensional objects. Students work in a variety of lively real-world contexts,…
