Lexical Analysis Identifies Different Lexical Units in a _______
A teacher in her grammar class introduces the grammar item in a text and in single sentences and draws the attention of learners to its use through lots of examples and activities by learners. Once the learners are able to use the language item in context, she familiarizes the rules of the grammatical in order to internalize the form. What is this process of teaching-learning grammar known as?
Arul Rahul, a teacher in his grammar class introduces rules of the grammar item, voice and tenses first and makes them understand how the form behaves and how to use it contexts. He then gives lots of tasks for learners to practice the language item. What is this process of teaching-learning grammar known as?
