Levels of Sophistication in Elementary Students Reasoning about Length
Battista, Michael T.
International Group for the Psychology of Mathematics Education, Paper presented at the 27th International Group for the Psychology of Mathematics Education Conference Held Jointly with the 25th PME-NA Conference (Honolulu, HI, Jul 13-18, 2003), v2 p73-80
Because cognition is the core substance of understanding and sense making, cognition-based assessment is essential for understanding and monitoring students' development of powerful mathematical thinking. The Cognition-Based Assessment System (CBAS) project is applying the results, theories, and methods of modern research in mathematics education to create an assessment system that can be used to assess in detail the cognitive underpinnings of the progress students make in developing understanding and mastery of core mathematical ideas in elementary school mathematics. In this report, I briefly describe initial CBAS research on the development of students' reasoning about length. [For complete proceedings, see ED500859.]
