After being released Alexander did pioneering work in the field of language policy and planning in South Africa from the early 1980s via organisations such as
The Project for the Study of Alternative Education in South Africa (PRAESA), as well as the LANGTAG process. He was influential in respect to language policy development with various government departments, including Education. His most recent work was focused on the tension between multilingualism and the hegemony of English in the public sphere. He founded and was director of PRAESA from 1992 until the end of 2011 and a member of the Interim Governing Board of the
African Academy of Languages. In 1981, he was appointed Director of the South African Committee for Higher Education (SACHED). At the time of his death, he had retired from being director of PRAESA at the University of Cape Town. Alexander received the
Linguapax Prize for 2008. The prize is awarded annually (since 2000) in recognition of contributions to linguistic diversity and multilingual education. The citation noted that he had devoted more than twenty years of his professional life to defend and preserve multilingualism in the post-apartheid South Africa and had become one of the major advocates of linguistic diversity. ==Death==
