Teaching Slang and Idioms To undertake and complete an ESL course
 To undertake and complete an ESL course would normally allow the  successful student to gain benefit from the ability to access the  English speaking world. By covering the four domains of speaking,  understanding, reading and writing a student would be able to  undertake activities such as answering conversational questions,  following a menu and writing a cheque. However, many students who  have completed a course containing these four basic domains of  language learning would continue to struggle when attempting to  fully interact and participate with other 1st language English  speakers. The main reason for this would be that they have not  included in their studies the learning of slang and idioms that  frequent the communication of 1st language English speakers.
This higher level language learning of slang and idioms would then  allow students greater access and ability to communicate at the same  level as other English speakers and undertake fundamental activities  such as following newspaper articles/TV programmes, participating in  humorous conversations and understanding song lyrics to name a few.  Unfortunately educators do not always recognise the need to include  the teaching of these higher level language skills of slang and  idiom as part of their teaching.
Idioms such as 'pull your socks up', 'I've got butterflies in my  stomach' and 'it's raining cats and dogs' would normally interpreted  literally by the inexperienced English language learner and thus  would cause embarrassment as they failed to realise the intended  meaning of 'try harder', 'I'm nervous' and 'raining hard' of the  above stated examples. Slang is used by all speakers of English and  can be specific to their individual profile. Slang is used in  business, the media, for example, 'kids' (for children), by  teenagers, for example, 'I'm landed' (for happy) and the elderly,  for example, 'leccy' (for electric). To be able to interact with all  those that use slang it is important for students to become  accustomed with the most commonly used terms because they would  otherwise miss fundamental aspects of the interaction if they are  not familiar with the terms.
There are increasing teaching materials available on the market for  teaching idioms and slang such as those by Winslow Press, which  highlights the increasing need to introduce this aspect of language  to all those wishing to learn. Actual examples of American movies  and song lyrics could also be used as a way of introducing slang and  idioms to students together with encouraging students to bring in  their own examples of phrases they do not understand in the context  they arise from. This is a particular problem with idioms and slang  because their intended meaning often has no relevance to the context  in which they are used. Students will often have to use rote  learning of the true meaning of slang and idiom most commonly used  before they can be understood in context. But as slang and idioms  often have an informal and humorous tone to them, the teaching of  them can provide a light hearted break to the often formal teaching  of basic speaking, listening, reading and writing lessons. Also,  once learnt, the students will benefit from increased confidence in  being able to fully interact and communicate rather than just simply  being a passive participant in English interactions.
In conclusion, the current approach to the teaching of language  using the typical four domains of language should be reviewed.   Teachers and students need to view language learning as a complete  holistic approach where the focus is on functional communication.  This approach would then need to encompass in each of these domains,  a higher level language element where the use of slang and idioms  when speaking, listening, reading and writing is a fundamental  aspect.
