Enhancement Of Mathematics Learning And Results Using Jigsaw Learning Models With Concept Niteni, Nirokke, Nambahi

This  study  aims  to  describe  the  process  of  learning  mathematics  using  the  JigsawLearning  Model  with  the  concept  of  TRI  N  (niteni,  nirokke,  nambahi)  to  improve  the  activity and  learning  outcomes  of  mathematics  class  VIII  D  SMP  N  2  Banguntapan.  This  research  is  a Classroom  Action  Research  (CAR)  conducted  in  two  cycles.  The  subjects  of  this  study  were students of class VIII at SMP N 2 Banguntapan, totaling 32 students. The object in this study is the  activeness  and  learning  outcomes  of  mathematics.  Data  collection  techniques  in  this  study were  carried  out  with  observation  techniques,  test  techniques,  and  documentation  techniques. The results ofthis study indicate the average percentage of student activeness from pre-cycle of 69.55% increased to 74.61% in the first cycle and 82.03% in the second cycle. Student learning outcomes test scores an average of 40.62% pre-cycle, the first cycle increased to 53.12% and the second cycle increased to 81.25%. Based on the  results of the study, the  implementation of the Jigsaw  learning  model  with  the  concept  of  TRI  N  (Niteni,  Nirokke,  Nambahi)  can  increase  the activeness and learning outcomes of students in mathematics.Keywords: Learning   Activity,   Learning   Outcomes,   Jigsaw,   TRI   N   (Niteni,   Nirokke,Nambahi).
