In 1992, ACDCA (Austrian Center for Didactics of Computer Algebra) began a conference series focusing on the use of symbolic calculation software in mathematics education. The first international conference dedicated to the use of the symbolic calculation software Derive took place in 1994. After that time, ACDCA and Derive conferences (to which the TI-92 symbolic calculator was added in 1996) were held in alternating years. In 2002, the two conferences were merged into one for the first time, in Vienna, Austria. In 2012, Derive conferences were renamed as "Conferences for CAS in Education & Research".
