(ICT) A Concordance Program (also known as a Concordancer) operates on a body of texts (a corpus) and is commonly used for compiling glossaries and dictionaries, e.g. by arranging every word in the text alphabetically or in order of frequency, together with its context. Concordance programs also play an important role in language learning and teaching, for example: (i) the teacher can use a concordance program to find examples of authentic usage to demonstrate a point of grammar, typical collocations, etc; (ii) the teacher can generate exercises based on examples drawn from a variety of corpora; (iii) language learners can work out rules of grammar and usage for themselves by searching for a particular key word in context (KWIC). Concordance programs form the basis of a methodology pioneered by Tim Johns, University of Birmingham, which he described as Data Driven Learning (DDL). See Module 2.4, Using concordance programs in the Modern Foreign Languages classroom, and Module 3.4, Corpus linguistics. See also: Data Driven Learning
