An Algorithmic Approach to Error Correction: An Empirical Study.

The article presents the effectiveness of using an algorithmic approach to error correction. This is a research to help Hong Kong English-as-a-second-language (ESL) learners overcome lexico-grammatical problems. Ten error types were used for the experiment with one set of remedial instructional materials designed for each. More than 450 secondary and tertiary level students were administered with pretests, posttests, and delayed posttest. A plenary review meeting was organized to gather feedback for the effectiveness of the approach.
