The task of teaching grammar in language courses is difficult because many American students lack a thorough grounding in the structure of their own language that could serve as a model framework for learning the grammar of another. It is helpful therefore for language teachers to stress parallel structures in the two languages, and to introduce grammar as early as the first day or two of class. No progression can take place without the tools that grammar provides. Although the particular instructional needs change with the learner's level, they do not end after 2 years of study. In order to progress towards mastery, grammar must play a part in all language activities on all levels. Various ways are suggested for facilitating grammar learning and strategies for reinforcement appropriate to different levels, without losing sight of the fact that grammar is only the skeleton. (LB)
