b Whilst-reading
Whilst-reading  becomes  the  main  activity  in  every  unit.  The  purpose  of this activity is to develop the students’ skills in reading. In this part, the students
are encouraged to be active and reflective. They have to be able to read aloud and understand  the  message  sent  by  the  writer  in  the  text.  This  part  will  provide  the
students with a reading passage related to the topic discussed and some questions to be discussed.
c Post-reading
This  part  provides  an  opportunity  for  the  students  to  develop  their  other skills since this part consists of communicative activities or reflection to find out
whether they are learning or not.
3. Developing Preliminary Form of Product
After  the  primary  planning  was  completed,  the  next  step  to  do  was  to structure  the  preliminary  form  of  instructional  materials  Borg  and  Gall,
1983:781.  Dealing  with  that,  the  writer  employed  Kemp’s  instructional  design step, namely developing instructional materials.
In  this  stage,  the  writer  determined  the  most  effective  and  efficient methods  and  then  selected  materials  to  provide  learning  experiences  that  could
support the attainment of the objectives. Thus, the writer decided the appropriate teaching-learning  activities  that  could  support  the  learners  to  achieve  the
objectives.
To encourage cooperation among the students so that they could help each other  to  learn,  cooperative  learning  is  also  employed  as  the  basis  in  designing
materials.  By  using  cooperative  learning,  it  is  believed  that  students  could  be encouraged  to  develop  communicative  competence,  to  appreciate  others,  to  help
each other, and to develop other social skills needed in the working place Richard and Rodgers, 2003:195. By helping each other to learn in pairs or small groups, it
is  believed  that  lower-achieving  students  could  feel  safe  and  confident  to  learn. Furthermore, using cooperative learning, the achievements of all students could be
raised. Considering this, informal cooperative learning group was then employed as  the  group  types  in  accomplishing  the  tasks  in  whilst-reading.  In  particular,
roundtable, jigsaw, and numbered heads were the types of the activities utilized. In designing the materials, instructional resources were selected to obtain
supporting  materials  that  could  motivate  the  students  to  learn.  Based  on  the consideration,  some  textbooks  and  websites  in  the  internet  were  selected  as  the
resources to obtain some texts or data, which further adopted to develop materials. The  instructional  resources  were  selected  to  obtain  some  reading  texts,  pictures,
and some theories on the language and text structure.
