Diagnostic E-Learning Trajectories Approach (DELTA)

Funded by the Boeing Corporation and the National Science Foundation

This is a major project to build diagnostic assessments, both paper-and-pencil and electronic, as well as diagnostic interview tools, for the learning trajectories identified by the Rational Number Reasoning Synthesis project, for students grades 3-8. Initially funded by the Boeing Corporation and more recently by the National Science Foundation, the project involves collaboration among our group at North Carolina State University, the Berkeley Evaluation and Assessment Research (BEAR) Center at the University of California, Wireless Generation, Inc., and local teachers.
