The background of this research was the importance of pronunciation to support the use of a language in a commuication. English, as an International language has quite different rules from our native language, Indonesian language. One of those rules is the matter of pronunciation. In English, there are long and short vowels. We can’t find this case in our language. Despite the fact that long & short vowels are important in pronouncing English words, our people sometimes feel difficult to pronounce them. Graphonics method is a new, simple, and innovative method that can be used to teach pronunciation. This method makes students easy to pronunce English words by recognizing the patterns of letters to represent certain sounds.
This research was conducted to respond the following questions:
1. How is the implementation of graphonics methods to facilitate 4th grade students of MI Al-Khoiriyyah 1 Semarang in the academic year of 2014/2015’ ability in pronouncing long & short vowels?
