An "intelligent" system for constructing computer-assisted pattern drills to be used in second language instruction is proposed. First, some of the difficulties in designing intelligent error analysis are discussed briefly. Two major approaches to error analysis in computer-assisted instruction, pattern matching and parsing, are described, and…

Elliptical sentence structures, i.e., restrictive sentences, play a decisive role in both the conventional and programmed approaches to foreign language instruction. Basic to both these approaches are four distinct phases: presentation, drill, contextualization, and testing. However, it has been proven that the learning process can be maximized…
