The purposes of this research are to test the effect of discussion learning method based lesson study on learning achievement and students activities. Learning method in control class use the conventional learning and in experiment class use discussion learning method based lesson study by using portfolio assessment. Cognitive learning achievement is analyzed with ANACOVA. Based on the analysis can be conclude that  discussion learning method based lesson study significantly affect on cognitive learning achievement (p=0.001).  Student activity is analyzed use Independent Sample T-test obtained p = 0.000. In other word,there are significantly differencesbetween students activities use discussion learning method based lesson study and conventional method.Student activity is also measured by Pa formula obtained: ask 76,25%; argued 83,12%; communicate with group 69,06%; and work together in group 78,28%.
