Project DELTA: Digital Environments for the Learning and Teaching of Algebra
Research Foundation of City University of New York
Project DELTA is a collaboration involving City University of New York, the Freudenthal Institute, and Horizon Research, Inc. Project DELTA will extend an existing library of 17 interactive CD-ROM digital learning environments on numbers and operations by adding an algebra strand. Each of the digital environments features classroom sessions that allow for exploration of a mathematics topic, children learning over time, and teachers' instructional techniques. HRI is leading the project's research on the impact of the new algebra materials on teacher development.
