Computer Assisted Language Learning (CALL) has been in use as a learner centered method since 1960. In this paper an attempt is made to evolve a Remedial Grammar (RG) which enables the teacher to develop a repertoire of remedial activities based on the errors identified following Error Analysis (EA) for repeated presentation. The error types are considered as teaching/learning points. The present paper argues that CALL is the right model for effective remedial learning. Remedial Gmaster (RGm), an authoring package is introduced. This is an exclusive mode of error correction in which interlingual, intralingual, developmental, and global errors are dealt with. The syntactical problems due to the subtle difference between simple past and perfect tenses in English language use are discussed and CALL authoring package presented. 展开更多
