14 implementation of a scripted role play in Play Performance class. Then, what the
students  learn  also  represents  the  implementation  and  perception  on  the  use  of  a scripted role play in  Play  Performance class.  Besides the perception, speaking is
the other point that would be explained further.
2. Speaking
In this part, there are some theories which are related to speaking.
a. The Nature of Speaking
Johnson  and  Morrow  1983  state  that  speaking  skill  or  oral communication  is  typified  as  an  activity  involving  two  or  more  people  as  the
hearers  and  speakers  having  to  react  to  what  they  are  and  make  their contributions.  It  means  that  the  person  who  is  speaking  should  have  at  least  one
listener. The speaker speaks to the listener and the listener listens to the speaker, just like having a conversation with friends in daily life. Brown and Yule 1983
also explain that speaking is to express the need-request, information, and service. Speaking  is  not  only  producing  sounds  but  also  a  process  of  transferring  the
messages to the person that the speaker is talking to. In  this  research  the  term  speaking
related to the students’ self confidence and  students’  pronunciation.  To  practice  speaking  in  English,  the  language
learners  need  to  boost  their  speaking  confidence  by  developing  their  learning strategies. It is because the more learning strategies language learners develop the
greater  confidence  they  will  gain  Nunan,  1999.  Hence,  building  the  speaking confidence is needed to improve the speaking ability through practicing since the
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
