Session Type: Symposium
Although fractions concepts play a critical role in the learning of algebra, students continue to fail at the mastery of fractions. This prompted the National Council of Teachers of Mathematics and the National Mathematics Advisory Panel to independently label fractions as one of the key areas for emphasis in the upper elementary and middle school mathematics curricula. This session highlights the recent findings of research groups from EDC, Carnegie Mellon University, Vanderbilt University, AIR and MDRC that are conducting long-term research projects about fractions. The individual papers presented in the session address research questions related to assessment development, technology development, and teacher professional development.
