Abstract

The  purposes  of  this  study  were  to  study  and  compare  mathematics  learning  achievement  and  mathematics  problem  solving  ability  of  Mathayomsuksa  2  students  who  were  taught by  student  teams  achievement  division  cooperative  learning  supplemented  with  Polya  problem  solving  process  before  and  after  learning. The research  sample  consisted  of  32  Mathayomsuksa  2  students  of  Sriboonruang  District, Nongbualamphu  Province. This  research  was  conducted  by  means  of  One  Group  Pretest-Posttest  design, using  cluster  sampling. The  research  instruments  were  lesson  plans, a  learning  achievement  test  and  a  problem  solving   ability  test. The  collected  data  were  statistically  analyzed  for  mean, percentage, standard  deviation  and  t-test  for  Dependent  samples.    


         The  research  findings  were  as s follows:


  1. The students  who  learned  through  student  teams  achievement  division  cooperative  learning  supplemented  with  Polya  problem  solving  process  had  the  pretest  mean  score  of  mathematics  learning  achievement  mean  score  was  9.97  or  33.23  percent  and  the  posttest  23.97  or  79.90  percent  which was  no  less  than  the  set  criterion  of  75  percent. The  posttest  mean  score  was  also  statistically  significant  higher  than  the  pretest. 

  2. The students  who  learned  through  student  teams  achievement  division  cooperative  learning  supplemented  with  Polya  problem  solving  process  had  the  pretest  mean  score  of  mathematics  solving  abilities  was  16.69 or  41.72  percent  and  the  posttest  mean  score  was  32.16  or  80.39  percent. The  posttest  mean  score  was  also  statistically  significant  higher  than  the  pretest.
