Though corruption eradication has been voiced out for such a long time, people see that corruption is even getting wilder and expanding. As an extraordinary crime, corruption must be fought extraordinarily. While strict rule of law, severe punishment – even death penalty-, and possibly social exclusion may be applied to those proven to have committed corruption, awareness on the harms of corruption must be introduced to young generation to prevent them from committing such crime. English lessons at schools can be the place where the awareness is instilled through the various presentations of learning materials as reading passages, conversation practice, writing practice, even grammar practice. Because of the flexibility of the nature of language learning, English lesson at school has the potential to be developed in such a way that promotes fight against corruption. This paper will elaborate how this idea can be implemented. It will start with the discussion of character building, topic of fighting against corruption found in existing English schoolbooks, and then is followed by elaboration on how the topic can be presented in English classes.
