<![CDATA[The purpose of this study was to determine the effect of example non example model to critical thinking skills and students learning activities. This research was experiment study with pretest-posttest design non equivalent group. The samples were two classes from MTs N 3 Lampung Selatan that were selected by purposive sampling. The quantitative data were obtained from the average value of test that were analyzed by using t-test and U-test. The qualitative data were learning activities and students responses that were analyzed descriptively. The result showed that example non example model influenced in critical thinking skills. Indicators of giving argument (p 0,003 0,05), induction (p 0,000 0,05), and doing deduction (th (0,482) tt (1,676)) have increased. Activities in experiment class was higher than control. Most of the students gave positive responses to learning model.
