English skills, the 'four skills' of listening, speaking, reading, and writing and other skills such as pronunciation, grammar, vocabulary, and spelling all play a role in effective English communication. The amount of attention you give to each skill area will depend both the level of your learners as well as their situational needs. Generally beginners, especially those who are nonliterate, benefit most from listening and speaking instruction with relatively little work on reading and writing. As fluency increases, the amount of reading and writing in your lessons may also increase. With advanced learners, up to half of your lesson time can be spent on written skills, although your learners may wish to keep their focus weighted toward oral communication if that is a greater need.
