ability  in  using  an  adequate  number  of  lexical  units  words  to  accomplish pragmatic purposes
Besides,  the  micro-skills  of  speaking  also  cover  the  ability  in producing fluent speech  at  different  rates of delivery, monitoring  one
’s own oral  production  and  use  various  strategic  devices,  producing  speech  in
natural  constituents, expressing a particular meaning in different grammatical forms, and using cohesive devices in spoken discourse.
Meanwhile, from those microskills of speaking stated by Brown, there are  some  skills  that  I  implemented  in  teaching  the  students  of  SMK
Muhammadiyah 3 Klaten Tengah. The microskills are: 1.
Using grammatical word classes nouns, verbs, etc., systems e.g. tense, agreement,  pluralization,  word  order,  patterns,  rules,  and  elliptical
forms. 2.
Producing  speech  in  natural  constituents:  in  appropriate  phrases,  pause groups, breathe groups, and sentence constituents.
f. Input
Input  is  very  important  for  students  because  it  can  give  them  the knowledge  needed  when  they  are  learning  to  speak  English.  The  general
term  of  input  might  include  a  variety  of  student  and  teacher  characteristics, such  as  intelligence,  sex,  personality,  general  learning  or  teacher  style,
previous  experience,  motivation,  attitudes,  and  so  on.  Brown  2007:  293 states  that  input  is  simply  the  process  of  comprehending  language  listening
and reading. Also, Krashen  1982  defines  that  optimal  input  should  be comprehensible,  be    interesting  and    or    relevant,    not    be  grammatically
sequenced,  and  be  in  sufficient  quantity.  It  is  because  if  the  leaner  can  be
exposed to input having to  these features, it is considered acquisition is more
likely to occur.
Moreover,  it  is  a  well-known  fact  that  audio-visual  materials  are  a great  help  in  stimulating  and  facilitating  the  learning  of  a  foreign  language.
According  to  Wright  1976:1  many  media  and  many  styles  of  visual presentation are useful to the language learner as long as they are used at the
right  time,  in  the  right  place.  In  language  learning  and  teaching  process, learner  use  his  eyes  as  well  as  his  ears;  but  his  eyes  are  basic  in  learning.
River  1981:399  claims  that  it  clearly  contributes  to  the  understanding  of another culture by providing vicarious contact with speakers of the language,
through both audio and visual means.
Finally, it is very clear that input is very needed by the students to be able  to  speak  English.  Without  any  input  received,  it  is  impossible  for  the
students  to  do  role  play.  They  will  not  know  how  to  produce  and  speak  the correct  English  utterances  for  their  role  play.  So,  in  providing  the  students
with  the  good,  appropriate,  and  clear  examples  of  role  play,  the  researcher
decided to use video as the input. g.
Video
One  of  the  most  appreciated  materials  applied  to  language  learning and  teaching  is  video.  According  to  Cakir  2006,  video  provides  authentic
language  input  for  the  students.  It  shows  them  how  people  behave  in  the culture  whose  language  they  are  learning  by  bringing  into  the  classroom  a
wide  range  of  communicative  situations  and  also  helps  to  promote comprehension.  Video  makes  meaning  clearer  by illustrating  relationships in
a way that is not possible with words, which proves a well-known saying that a picture is worth thousand words.
Moreover,  Harmer  2001:  282  claims  that  video  can  give  students realistic  models  to  imitate  for  role-play;  can  increase  awareness  of  other
cultures  by  allowing  the  students  to  look  at  situation  far  beyond  their classroom, creation and motivation. Also, there are three basics type of video
which can readily be used in class: off-air programmes, real world videos, and language learning videos.
1. Off-air programmes
Off-air  programmes  are  programmes  that  are  recorded  from  a television  channel.  When  using  this  kind  of  video  as  an  input  for
our  students,  we  have  to  the  make  sure  that  the  programmes  are engaging  for  our  students,  have  a  sensible  length,  and  easy  to
understand.  All  television  programmes  also  have  copyright restrictions  which  vary  from  country  to  county,  so  it  is  very
important to know what that law is and realise that breaking it can have serious consequences.
2. Real-world videos
There  is  no  reason  why  we  and  our  students  should  not  use separately  published  videotape  material  such  as  features  films,
exercise’s  manual  or  comedy  that  there  are  no  copyright
restrictions for doing this. However, once again,  we need to  make our choice based on the length, how engaging and comprehensible
the extract is likely to be. 3.
Language learning videos Many  publishers  now  produce  video  to  accompany  coursebooks.
The main advantage of specially made video is that they have been designed  with  students  at  a  particular  level  in  mind.  They  are
comprehensible, designed to appea l the students’ topic interest, and
multi-use. Furthermore,  in  teaching  the  students  of  grade  X  Nursing  class  of
SMK  Muhammadiyah  3  Klaten  Tengah,  I  used  the  real-world  videos.  The videos that I used entitled at the doctor and the doctor and the patient. The first
video  was  about  a  nurse  that  making  an  appointment  for  a  patient  who  was going to see the doctor. Then, the second video was about a doctor who was
threating his patient in a hospital. However,  even  though  video  is  a  good  input  for  students  in  learning
English,  there  are  some  disadvantages  of  video  that  should  be  taken  into account.  The  main  disadvantages  are  cost,  inconvenience,  maintenance  and
some cases, fear of technology. Additionally, the sound and vision, quality of the  copies  or  home-produced  materials  may  not  be  ideal.  So,  the  teacher
should be well-trained on using and exploiting the video. The teacher can also be a controller, an assessor, an organizer, a prompter and a participant as well.
