This method of research is pre-experiment with pretest-posttest design. The data collection technique used is test technique and the data processing used is statistics t test. From the hypothesis test processing can get count t value > ttable (2,219> 1,67). Thus, we can conclude that application of peer tutoring methods at the oxidation reaction and reduction reaction is be able to increase achievement chemistry learning by students of X grade SMAN 1 Ukui to increase student achievement by 8,4%.en-USpeer tutoring methodsthe learning achievement of studentstudent Paper Post Degree
