Based on the observation and interview above, the expressive function is often used in her classroom. Teacher B feels that changing the expressive sentence
into Indonesian language is suitable. But, I do not think so. The expressive function can be changed into English without changing the purpose. The teacher
can use English expression in the classroom to express her feelings. In addition, it can make the students more familiar with the English expression that the teacher
used.
7. Poetic function
Last function of code switching which was found in the observations is poetic function. Poetic function is used when the speaker switches their language
into the other language in informal way. It includes jokes, stories, even ice breaker. This function was found in each teacher once. Teacher A used poetic
function once in 0,5 while teacher B used this function once in 0,45. Teacher A used this function in the third observation while explaining
descriptive text about Tukul Arwana, Indonesian comedian artist. The finding of
poetic function was presented in dialogue below,
T: ……. Who is that? S: Tukul
T: Okay Tukul Riyanto. Bukan Priyanto. „He‟s Tukul Riyanto not
Priyanto‟ S: laugh

Teacher A inserted jokes in the middle of explaining the descriptive text by saying
„bukan‟ instead of „he‟s not‟. Teacher B also inserted jokes in her teaching which was found in the first observation. She said,
S: Makan bu „Eating ma‟am‟
T: Emangnya kamu „It‟s you. Not us
This function was used by both teachers to make the students laugh in the middle of learning process. It made them relax and enjoy the lesson even not
bored while learning. This function also explained by teacher A in the interview, “I use jokes in Bahasa Indonesia, because if I used jokes in
English, I don‟t think they will understand. In addition, it can get their attention and refresh their mind for a while. So, they will not get stress and
under pressure. So, I need some jokes to make them more relax and I used English since they are not familiar with English jokes.”Teacher A,

“I insert some jokes in Indonesian language because sometimes they don‟t understand when we use English to joke. I want to use English,
but if I say it in English they like, „What?‟ There is no reaction.”Teacher B, Interview, July 10

, 2015 Both of the teachers explained the same reason why they used jokes in
Indonesian language. It is because the students cannot understand English jokes. In addition, they are not familiar with English jokes. I also think that joke is quite
important in learning process. But, I don‟t agree that this function is useful for
learning. It will be much better if the teacher can reduce the Indonesian language slowly. It is useful to enrich the students‟ English vocabulary in enhancing
English learning.
