Subject Taxonomy

Core Subject Taxonomy for Mathematical Sciences Education

• Mathematical Sciences Conference Group on Digital Educational Resources
• Math Gateway Partners Group

This taxonomy is based on the Math NSDL Taxonomy Committee Report, April 2, 2002, with draft changes proposed for Section 9 by CAUSE, May 16, 2004. Further changes to Section 9 were approved by the Math Gateway Partners Group, April 29, 2005

The first two levels of this taxonomy are used for classifying JOMA documents by subject matter.  A fuller indication of the meanings of those levels may be obtained by scanning the deeper levels.
