Direct linkWeiland, Christina; Wolfe, Christopher B.; Hurwitz, Michael D.; Clements, Douglas H.; Sarama, Julie H.; Yoshikawa, Hirokazu – Educational Psychology, 2012
In recent years, there has been increased interest in improving early mathematics curricula and instruction. Subsequently, there has also been a rise in demand for better early mathematics assessments, as most current measures are limited in their content and/or their sensitivity to detect differences in early mathematics development among young…

Peer reviewedBattista, Michael T.; Clements, Douglas H.; Arnoff, Judy; Battista, Kathryn; Van Auken Borrow, Caroline – Journal for Research in Mathematics Education, 1998
Defines spatial structuring as the mental operation of constructing an organization or form for an object/set of objects. Examines in detail students' structuring and enumeration of two-dimensional rectangular arrays of squares. Concludes that many students do not see row-by-column structure. Describes various levels of sophistication in students'…

Peer reviewedClements, Douglas H.; Swaminathan, Sudha; Hannibal, Mary Anne Zeitler; Sarama, Julie – Journal for Research in Mathematics Education, 1999
Investigates, by conducting individual clinical interviews of 97 children ages 3 to 6, the criteria preschool children use to distinguish members of a class of shapes from other figures, emphasizing identification and descriptions of shapes and reasons for these identifications. Concludes that young children initially form schemas on the basis of…

Barrett, Jeffrey E.; Clements, Douglas H. – Cognition and Instruction, 2003
This article describes how children build increasingly abstract knowledge of linear measurement, emphasizing ways they relate space and number. Assessments indicate children struggle to understand measurement, especially concepts related to complex paths as in perimeter tasks. This article draws on developmental accounts of children's knowledge of…

Peer reviewedClements, Douglas H.; Battista, Michael T. – Journal for Research in Mathematics Education, 1990
Presented is a study which focused on using turtle graphics programing for geometric problem solving. The goal was to investigate changes in children's mathematical knowledge and results indicate that the LOGO environment enriched children's geometric conceptualizations and sophistication of their geometric thinking.

Although geometry and spatial reasoning are important as a way to interpret and reflect on the physical environment and also form the foundation for learning mathematics and other subjects, many early childhood and primary school teachers spend little time instructing their students in these areas. This paper examines how young children learn…
