The difference between TSG and Grammar in context is that TSG was used to teach student in a better way of learning grammar, is a set of assumption about how grammar usage is best learned rather than a specific course of study. However, grammar in context will allow learners to see how rules can be used in sentences. Teaching grammar is to show how language Works. Context-based grammar holds an important place for effective learning. Grammar changes because the needs of its speakers change. New technologies, new products, and new experiences requires new words to refer to them clearly and efficiently. Many of the changes that occur in language begin with teens and young adults. As young people interact with others their own age, their language grows to include words, phrases, and constructions that are different from those of the older generation.It will be more motivating for learners if grammar is taught in context as students will have an opportunity to know how the new grammar structures work. Grammar rules are made easier if they are given in a context and teaching grammar in context gives an accuracy in the target language.
