4. Preliminary Field Testing
In this step, the researcher asked the feedback from the experts related to
the materials designed. The experts were the English teacher of SMK N 2 Depok, Sleman,
Yogyakarta  and  lecturer  from  English  Language  Education  Study Program  of  Sanata  Dharma  University.  The  preliminary  field-testing  was
conducted  by  analyzing  the  preliminary  form  or  the  draft  of  the  book  results which  are  distributed  to  the  experts  in  order  to  detect  the  weaknesses  in  the
designed  materials.  The  researcher  also  conducted  a  post-interview  with  both experts  to  make  the  feedback  clearer.  Table  4.7  showed  the  background  of  the
respondents.

The result of the interview was quite good. They said that the design was good, but  it still needed  a lot of improvements.  The teacher  said
“It is ok if you make a lot of mistakes because you are still beginner in this field.” Then both of
them criticize the same point. They said that they felt difficult to find correlation between  the  designed  materials  and  the  syllabus,  so  they  wished  that  the
researcher  paid  attention  to  it.  The  sample  of  the  questions  can  be  seen  on appendix E page 68. In addition, the researchers also obtained the data in a form
40 of  written  feedback  on  each  page  design.  Those  feedbacks  was  very  useful  to
improve the final design of the English speaking materials.
5. Main Product Revision
After  gathering  the  data  through  the  field-testing  step,  the  researcher revised the designed materials based on the evaluation and feedback results from
the experts. The revision was applied in order to produce a good design.
B. The Description of the Speaking Materials Design
This parts deal with the description of the designed materials. Because of the  limit  of  time,  the  designed  material  only  consist  of  4  units  and  could  not  be
implemented. Unit 1: We are surrounded by it
Unit 2: It’s not the technology, it’s how we use it Unit 3: I am the Boss
Unit 4: Learn through Music The  book  titled,
“ENGLISH  FOR  BRIGHTER  FUTURE”  designed  as  English learning materials for SMK N 2 Depok, Sleman, Yogyakarta grade XII. The level
of the difficulty that the researcher used is intermediate level. Unit 1 We are surrounded by it was made because the researcher want to
introduce their working place in the future. The word “it” in the subtitle “We are
surrounded by it” refers to industries. Unit 2 It’s not the technology, it’s how we use it was made because the researcher want to persuade the students to use the
