DEM MAJOR DESCRIPTORS

audiovisual-aids in dem

Descriptors are controlled vocabulary terms or subject headings from the Thesaurus of ERIC Descriptors, used to group documents on similar topics.

Major Descriptors (DEM) denote primary topics and are preceded by an asterisk in displayed records. Although you can search with the DEM field abbreviation, all Descriptors display with the DE field label.

For most precise results, search Descriptors as hyphenated, "bound" phrases. Hyphenate single-word Descriptors, such as dyslexia- in de, to limit the search to the single-word Descriptor.
