<![CDATA[The background of this research was the low mathematic concept comprehension of the students; also students prefer to ask to their friends instead to ask to their teachers. The purpose of this research was to know the improvement of mathematic concept of the students with application of practice-rehearsal pairs type of active learning strategy in mathematics learning of grade VIII of MTsTI Batang Kabung Padang and to know whether students mathematic concept comprehension was better with the application of practice-rehearsal pairs type than students mathematic comprehension with application of conventional learning of grade VIII of MTsTI Batang Kabung Padang. The type of the research was experimental research, with random research planning toward the students. The population of the research was grade of MTsTI Batang Kabung students in academic year 2013/2014. The technique of sampling was random selection, and class VIIIc was chosen as experiment class and class VIIId as control class. The instrument of the research was final test of mathematic concept comprehension in form of essay with reliability was 0.92. The technique of data analysis was using test t one head with help of MINITAB. Based on the result of data analysis known that both sample distributed normally and homogeneity. The result of hypothesis resulting P-value was 0.044 which mean less than α = 0.05, so the research hypothesis is accepted. It can be concluded that studentsâ mathematic concept comprehension using practice-rehearsal type of active strategy was better than studentsâ mathematic concept comprehension than conventional learning with 95% level of trust. ]]>
