The purpose of this study is to improve  learning outcome of science with style material through jigsaw cooperative learning model application of fifth grade student of state elementary school of O I   Kepatihan, Selogiri  subdistrict, wonogri regency, lesson year 2010/ 2011.
The form of this research is clase action research by using 2 cycles. Each cycles consist of 4 stages : planning,  implementation  of the action,  observation, and  reflection.  As  the  subject  of research  are  fifth  grade  students  of  state elementary  school f 01 Kepatihan,  Selogiri sub district,  Wonogiri regency.  The data is collected by doing observation and test. Data analysis Techiques which are used:  analysis  and  interactive  model,  wich  has  3   components,  namely  data reduction, data  presentation,and conclusion drawing or verification.
Based on the research can be concluded that thought the application  of jigsaw  cooperative learning model can improve learning outcome of science with style material of fifth grade student of state elementary school of O I   Kepatihan. Based of the result was obtained that students  learning outcome  has completed before  the action  are 20 students, cycle I  there are 14  students and cycle llthere are  19  student.  The percentage of the number of learning  outcome of cycle II is 95%,  that value has already fulfilled the research indicators. The average learning outcome  before action is 65, learning outcome of cycle I  is  n73, Cycle 11   is 82. Details of average cognitive, affectife, and psychomotor as follows :  cycle I as on average value of cognitive aspects is 67, cycle 11  is 71.  Affective aspects of cycle
11  is 89. This it can be put forward as a recommendation that ultimately the jigsaw
cooperative  learning  model application  ca improve learning  outcome of science with  style  material  of fifth  grade  students  of state  elementary  school  of O I Kepatihan, Selogiri sub district, Wonogiri regncy.
