3.7 Procedure of Collecting Data
The experimentation was conducted as follows: 1
Choosing the eighth grade students of SMP Negeri 1 Pati as the population of the study.
2 Taking 2 classes randomly as the samples, one class is experimental class
and the other class is control class. I took class VIII-A as the experimental class and class VIII-B as the control class.
3 Conducting try out test to know the validity and reliability of the
instruments. I took class VIII-G as the Try-Out class. 4
Doing the real experimentation.
3.7.1 The Activities of The Experimental Class
a Pre-test
Pre-test was given firstly before doing the treatment. The pre-test is aimed at  finding  out  the  basic  knowledge  or  the  prior  knowledge  and  the
students‟  ability  in  reading  a  recount  text.  Firstly,  I  came  to  the  chosen class. Then  I explained to the students about what they were going to do.
Then I distributed the instruments and asked them to do the pre-test. b
Activities in the Treatment In  an  experimental  study,  treatment  is  usually  done  to  find  out  the
difference  between  the  two  classes  which  are  treated  by  using  different
techniques. The experimental class  was treated by  using the visualization in desuggestopedia teaching method to do reading a recount text. Then, the
students applid them in recount text. The materials of the treatment, which I  gave,  are  as  follows:  what  recount  text  is;  what  the  rhetorical  steps  of
recount  are;  what  visualization  in  desuggestopedia  teaching  method  is; how the the visualization in recount text is carrried out.
c Post-test
I administrated the post-test at the end of the experimental activities. It is aimed  at  finding  out  whether  there  is  significant  difference  between  the
result  of  pre-test  before  doing  the  treatment  and  after  conducting  the treatment. In other word, conducting the post-test is aimed at showing the
result of students‟ achievement after doing the treatment. Table 1.4 List of Experimental Class Activities
