The present study was designed to examine the effects of differences in the evaluation-subject and the evaluation-object on calculation skill and self-efficacy in drill practice. Two conditions of the evaluation-subuject (evaluation by the class teacher and self-evaluation) were crossed with two coditions of the evaluation-object (results and solution process). Seventy three schoolchildren of the low scholarship participated in the experiment. One of the main results showed that self-evaluation of the solution process increased the score in the posttest. Another result showed that score of the self-efficacy were increased in the condition that evaluation by the experimenter. These results were discussed in terms of one's view of learning.
