Discussion of problems in computer assisted instruction focuses on poorly written software and the role of computer programing. Use of computers without programing knowledge is discussed, and pragmatics is emphasized as the discipline needed to supplement syntax and semantics in the field of computer science.

Noting that expert computer systems respond to various contexts in terms of knowledge representation, this paper explains that heuristic rules of production, procedural representation, and frame representation have been adapted to such areas as medical diagnosis, signal interpretation, design and planning of electrical circuits and computer system…

Describes principles underlying ILLICO, a generic natural-language software tool for building larger applications for performing specific linguistic tasks such as analysis, synthesis, and guided composition. Shows to what extent this approach is relevant to the development of computer-assisted language-learning systems. (Author/VWL)

Presents methods for using the Longman Mini-Concordancer on tagged and parsed corpora rather than plain text corpora. The article discusses several aspects with models to be applied in the classroom as an aid to grammar learning. This paper suggests exercises suitable for teaching English to both native and nonnative speakers. (13 references)…

Discusses the need to provide learner-directed computer-assisted language learning (CALL) for mature students to perfect their English. Topics addressed include expert procedural knowledge, including lexical, grammatical, and discourse skills; and expert domain knowledge, including dictionaries and thesauri, tagged corpora, and discipline-specific…
