The results were obtained average value pretest metacognitive ability of experiment class is 44 with a deviation standard of 16.92 and the control class 43 with a deviation standard of 15.47. Based on tail two test (pretest) tcount = 0.84 and ttable = 1.997 so the beginning of the second class of sameability. While the average valuepostest of ability metacognitive experiment class was 82.74 with a deviation standard of 9.9 and the control class 76.74 with a deviationstandard of 11.76. Based on tail one test (posttest) obtained tcount = 2.999 and ttable = 1.669 so tcount> ttable so Ha is accepted.
