Third,  the  researcher  interviewed  the  English  teacher.  The  interview  was aimed  to  strengthen  the  findings  about  the  reasons  for  code  switching  and  the
effects of code switching in teaching English to the first semester students of the third grade in SMP Karitas Ngaglik toward English learning.
E. Data Analysis Technique
Data  analysis  is  a  process  of  gathering,  modeling,  and  transforming  the data with the goal of highlighting useful information, suggesting conclusions, and
supporting decision. The researcher analyzed the data gathered in the research in order to gain the answer to the question formulated in the problem formulation.
First the data were analyzed by classifying the words or sentences of code switching into the types of code switching based on the data from the observation
sheet and the  notes taken  in the classroom.  The  data were classified  into the  six types  of  code  switching  according  to  McCormick.  They  were  classified  by
checking   the  column  of  the  types  of  code  switching  in  the  checklist  and
grouping  them  into  the  types  of  code  switching.  The  types  are  diglossic  code switching, situational code switching,  metaphoric code switching, conversational
code  switching,  single-word  code  switching  and  integrated  loanwords  code switching.  But,  in  order  to  make  the  readers  understand  the  findings  and
discussion easily, the researcher rearranged the arrangement of the types of code switching from the shortest type to the longest type. The types of code switching
would  be  presented  in  this  order:  integrated  loanwords  code  switching,  single word code switching, and conversational code switching which had three smaller

types  phrase  code  switching,  clause  code  switching,  whole  sentence  code switching.  Then,  the  researcher  counted  the  amount  of  cases  in  each  type  and
made it in percentage form. The data were analyzed by using this formula.
N = × 100
Where  N  is  the  percentage  of  the  classified  code  switching,  n  is  the amount of the cases of classified code switching,
n is the amount of the cases of code switching that exists in the classroom.
Second,  the  data  were  analyzed  by  collecting  twenty  five  questionnaires from  the  students.  From  the  questionnaire,  the  researcher  grouped  the  answer
based  on  the  similarity  of  the  answer.  The  data  were  analyzed  by  using  this formula.
N = × 100
Where  N  is  the  percentage  of  the  answer,  n  is  the  amount  of  the  same answer,
n is the amount of the questionnaires. Third,  the  researcher  collected  the  answer  from  the  teacher  about  the
reasons  for code switching  in teaching English and the  effects of code switching in teaching English to the first semester students of the third grade in SMP Karitas
Ngaglik towards  the  students’  understanding  about  the  materials  taught.  The
researcher made the summary of the answer of the teacher.
