Historically in the U.S., support for oral methods prevailed until dissatisfaction with the continued low reading levels of deaf students prompted many to revolt against oral English-based methods and advocate for the use of a signed language. The assumption of some who supported the use of a signed language versus spoken English was it is the language (i.e., English) instead of the communication mode (i.e., speech) that presents special difficulty for deaf children, and that signed languages (i.e., American Sign Language) are learned more easily than traditionally spoken languages, including English. A number of systems of manually coded English were developed that incorporated signs borrowed from American Sign Language, the word order of English, and additional invented signs to convey morphological elements such as plurals and affixes. Proponents believed that these systems allowed students to develop English vocabulary and syntax. Examples of these systems included: Seeing Essential English or SEE I (Anthony, 1971), Signing Exact English or SEE II (Gustason, Pfetzing, & Zawolkow, 1972), and Signed English (Bornstein, Saulnier,& Hamilton, 1973-1984). These systems have been in widespread use. However, reading levels of deaf students today are virtually the same as they were in the mid-1960s.
