<![CDATA[his research aimed at knowing the implementation of auditory intellectually repetition (AIR) learning model on student cognitive learning result on the Environmental Pollution learning material. The research approach used is quantitative descriptive. The research method used is experiment type Quasi-experiment with design research Nonequivalent Control Group Design. The population in this study is all students of class VII SMPN 7 Dedai. Samples are VIIA and VIIB classes. The sampling technique used was purposive sampling technique. The data collection instruments used were observation sheets, questions test, and questionnaires. Data analysis for obesrvation and questionnaire by percentage and for test with parametric statistic that is t-test of two samples. The result of analysis on teacher observation sheet at the first and second meeting obtained an average value of 97.70%, belonged to very strong criteria, while the analysis of student observation sheets at the first and second meeting obtained average value of 95.45% belonged to very strong criteria. Based on the posttest hypothesis test on the experimental and control class obtained tcount was 14,77 and ttable was 2,00665. Testing the hypothesis proves that tcount> ttable(14,77> 2,00665) which means Ha accepted and Ho rejected. Hence, it was proved that there was a significant difference on students' cognitive learning result on the Environmental Pollution learning material between the experimental class and the control class. Based on the students' response questionnaire processing is obtained by the average percentage value of 86.81% belonged to strong category]]>
