Previous Study THEORETICAL FRAMEWORK
Demonstration technique emphasize toward learning visually. In learning vocabulary through it, the students and teacher can use by mime, gesture, or action. In
one of books tell about demonstration technique by mime, action, and gesture is one of examples of vocabulary teaching technique because the vocabulary becomes easy
if presented in this way. According to Harmer in previous explain , “Action, in
particular, is probably better explained by mime. Concepts like running or smoking are easy to present in this way; so are ways of walking, expressions, prepositions, and
times.” It is teaching vocabulary by using demonstration technique through mime, action, or action, which is will help the teacher or students explain the vocabulary
with hand or body movement. Another resource from one of journals, demonstration technique involves the teacher and the students showing, which is how to do
something. Demonstration can be done to be effective with both large and small groups. The other words that teaching vocabulary through demonstration technique
will help the teacher or students to introduce new words easily and it make the students active in the classroom. It is caused this way more effective which is the
teacher just as facilitator and the students doing social interaction in learning process, than other conventional techniques.
To sum up based on all descriptions above, the writer assumes basically vocabulary is knowledge of word mean and it is important part of in learning foreign
language. Mastery of vocabulary will help the students’ problem who cannot be able
in English fluently. Therefore, learning vocabulary in English is very important factor. But remember that the teacher has to make the students become interest and
make them enjoy and easy when learn English vocabulary. So, the teacher has to be creative in using teaching technique. One of the teaching techniques is by using
demonstration technique. In here, the teacher and students can do something in introducing the English words by mime, action, or gesture. Therefore, demonstration
technique gives good impact to stimulus in improving the students’ vocabulary
because the students learning by doing and has social interaction in learning process.
It differences with other techniques that usually just emphasize students’ memorize
individually in learning vocabulary.
