Learning English Language Grammar!

Many English learner especially Asian learner assume that learning English grammar is useless and old-fashioned.
That could be true, because the traditional way of Language Teaching was 'The Grammar Translation Method'. It is known as the Classical Method means classic! lol
A historical foundation of Language acquisition should be set in the context of a prevailing since of absence of possibility of communication between different language users.
Especially, Latin was taught by focusing on grammatical rules, memorization of vocabulary and of various declensions and conjugations, translations of texts, doing written exercises. That is why the method is called CLASSICAL METHOD.

To make a long story short, learning grammar is necessary for foreign language learners as long as they are not highly accustomed to the target language.
Many new language learners are willing to take language proficiency tests, such as TOEFL or the IELTS, in the case of English.
Those tests have Writing and Speaking sections. Without comprehension of the grammar of one's target language, it is impossible to study those sections, since knowing how to use the language possibly make the student to correct oneself his/her errors one made.
Although Richards & Rodgers pointed out, 'it has no advocates. It is a method for which there is no theory. There is no literature that offers a rationale or justification for it or that attempts to relate it to issues in linguistics, psychology, or educational theory.' they stressed that 'remembered with distaste by thousands of school learners, for whom foreign language learning meant a tedious experience of memorizing endless lists of unusable grammar rules and vocabulary and attempting to produce perfect translations of stilted or literary prose'.
It is the very first step in language learning to memorizing. And the next step could come to the level of self-correction.
As long as we, learners, are in the level of those two very basic, we cannot help giving effort on bearing the tunnel of these boring steps.
