G. Research Procedures
1. Conducting library study
In the first, the writer studied the relevant theories and literatures. Since the curriculum was based on School Based  curriculum SBC, the writer learned the
theories  and  principles  about  SBC,  which  were  already  discussed  in  Chapter  II. Other  theories  that  were  used  in  this  study  are  books  about  some  theories  of
descriptive  speaking,  curriculum  development,  language  learning  assessment, approach, method and technique and instructional design.
2. Conducting need survey
The  need  survey  was  conducted  by  doing  observations,  distributing questionnaire, and conducting  interviews. The interview was conducted once for
an English teacher of SMA N 1 Ngaglik. The questionnaire was done by the 11
th
grade students of SMA N 1 Ngaglik.
3. Developing English speaking materials
The materials were developed based on the need analysis. PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI

gather the evaluations, criticism, and suggestions.
5. Revising material
Based  on  the  result  of  evaluations,  the  design  material  would  need  some revisions,  improvements,  and  reconstruction  to  make  the  design  better.

CHAPTER IV RESEARCH FINDINGS AND DISCUSSION
In  this  chapter,  the  writer  would  like  to  answer  two  research  problems stated in Chapter I. This chapter is divided into three main parts. The first part is
the elaboration of steps in designing the materials. This  reveals the steps of how a set  of  speaking  instructional  materials  using  mind  mapping  for  the  11
th
grade students  of  SMA  N  1  Ngaglik  is  designed.  The  second  part  is  the  discussion  on
materials evaluation. It presents responses to the evaluators‟ opinion, suggestions,
and  criticisms.  The  third  part  is  the  presentation  of  the  set  of  speaking instructional materials using mind mapping for the 11
th
grade students of SMA N 1 Ngaglik looks like.
A. Steps in Designing Speaking Instructional Materials
This  part  presents  the  discussion  to  answer  the  first  question  on  the problem  formulation  that  is  how  a  set  of  speaking  instructional  materials  using
mind  mapping  for  the  11
th
grade  students  of  SMA  N  1  Ngaglik  is  designed. Hence,  the  writer  proposed  nine  steps  of  the  research  theoretical  framework  by
considering  some  instructional  design  models  of  Yalden‟s  1987  and  Kemp‟s 1977. The steps were in line with the first five steps of RD.
