15 confidence  is  learned  through  process  Goel,  2012.  Besides,  Klein  1986
confirms that adult learners are capable of improving pronunciation by practicing the  speaking  English.  In  the  next  section,  the  researcher  wants  to  explain  the
development of speaking ability.
b. Development of Speaking Ability
According to Harmer 1998, there are two elements of speaking. The first element is knowledge of language features and the second element is the ability to
process  information.  Knowledge  of  language  features  includes  the  ability  to produce  individual  phoneme,  to  use  fluent  connected-speech,  expresses  devices,
lexical  and  grammar,  and  negotiation  language.  Then,  the  ability  to  produce information includes language processing, interacting with others, and on the spot
information processing. Willis  1981  suggests  several  activities  that  can  be  used  to  improve  the
students’  speaking  ability.  They  are  conversation  drill,  using  picture  cues, imaginary  situations,  and  role  play.  In  this  study,  the  researcher  focuses  on  the
role play as the activity which can improve students’ speaking ability. A role play teaches  the  students  to  be  confident  in  speaking  in  front  of  people.  Teaching
speaking is the next section explained by the researcher.
c. Teaching Speaking
The  goal  of  teaching  speaking  skill  is  to  communicate  efficiently.  The students  should  be  able  to  make  themselves  understood,  using  their  current
16 proficiency to the fullest. They should try to avoid confusing in the message due
to faulty pronunciation, grammar, or vocabulary, and to observe the social cultural rules that apply in each communication situation Burnkart, 1998, p.2.
Rivers  1968  states  the  teaching  of  speaking  skill  is  more  demanding  on the  teacher  than  teaching  of  any  other  language  skills.  It  is  important  to  the
teachers to give an opportunity for students to practice speaking. Bailey  Savage 1994 suggest five principles in teaching speaking, as follows:
1 Awareness  of  the  differences  between  second  language  and  foreign
language learning context
A foreign language is one where the target language is not the language of communication  in  society.  The  challenge  of  teaching  speaking  in  the  foreign
language learning context is that the students will not have many opportunities to use  the  target  language  outside  the  classroom  because  the  target  language  is  not
the  language  of  communication  in  community.  Meanwhile,  the  challenge  of teaching  speaking  in  second  language  learning  is  that  language  is  the
communication language in society, the students’ speaking ability is  quite good but  sometimes  their  speech  seems  to  stop  developing  when  they  still  do  some
language errors.
2 Giving students practice in fluency and accuracy
In  the  language  learning,  the  students  must  develop  their  fluency  and accuracy by using the opportunities to speak. To help them develop those things,
the  teacher  should  minimize  to  interrupt  them.  The  teacher  should  give  them
17 feedback  after  finishing  their  speaking  therefore  the  students  could  not  be  afraid
of speaking and making errors.
3 The  importance  of  group  work  or  pair  work,  and  limiting  teacher
talks
In  teaching  speaking,  the  teacher  should  limit  the  talking  in  front  of  the classroom. However, the teacher should give the opportunities for the students to
talk. Bailey  Savage 1994 state that the pair works and group works activities can  be  used  to  increase  the  amount  of  time  that  the  learners  get  to  speak  in  the
target  language  during  lessons.  Therefore  a  pair  work  or  a  group  work  makes students learn to speak the language effectively.
4 Involving negotiation for meaning
The negotiation for meaning is the interaction to communicate in the target language in order to understand and to be understood. The teacher should provide
time which involves the process that is called negotiation for meaning.
5 Involving  guidance  and  practice  in  both  transactional  and
interactional speaking
The  difference  between  the  transactional  and  interactional  speaking  is  on the purpose. The purpose of  the transactional  is  primarily on the meaning of the
message but the interactional speaking is focusing on maintaining and establishing social relationship. The next section will discuss the nature of role play.
3. Scripted Role Play
In this part, there are some theories related to scripted role play.
