Based on the average value obtained by the students at the end of the first cycle can be seen that the W after the given action I got 50%, the S gets a value of 50%, T gets the value of 40%, a gain value of 40%, R gets the value of 50%, and Kalsogot50%. The results of the second cycle Showed an increasing ability of the child. Where W after being given a second act gets a score of 70%, the S gets the value of 80%, T gets the value of 60%, a gain value of 60%, the R gets a score of 70%, and K got 60%.
