<![CDATA[the objective of this study is to know the effectiveness of using concept map media to improve the success of learning accounting with the sub-topic is Classification of Account for XI students 1st semester in SMA Negeri 3 Pekalongan year 2005/2006. Population of the research was all XI students semester 1 SMA Negeri 3 Pekalongan year 2005/2006 with the numbers were 232 students divided into 6 classes.

The result of t-test showed that the average of learning achievement of experimental group was better than controlled group. It can be concluded that the using of concept map as learning media sub-topic on classification account is more effective than the group without concept map media.
