This research is motivated by the lack of interest of the students to read the lessons that will be studied and the students comprehention of mathematical concepts are still low , causing the outcomes of mathematics are also low. This research aims to: 1 ) Knowing how to implement student learning activities with elaboration strategies methods includes Preview, Question,  Read, Reflect, Recite and Review ( PQ4R ) on mathematics class VIII SMP 2 Payakumbuh. 2) Determining whether the student with an comprehention of mathematical concepts with implementation strategies elaboration of the method include Preview, Question, Read, Reflect, Recite and Review ( PQ4R ) more understand than conventional learning students in class VIII SMP 2 Payakumbuh. The type of this research is experimental research, the entire study population class VIII SMP 2 Payakumbuh. The sampling is randomly, selected VIII-D class as the experimental class and the control class is VIII-E class. Hypothesis test that used was T test. Form of the test used essay test with a reliability test is  = 0.72 , the meaning that test has high reliability. Based on the analysis of both,  have average that studentâs understanding of mathematical concepts on the experimental class = 69.68, and average studentâs understanding of mathematical concepts on control = 59.06. The hypothesis , derived P â value = 0.018 < ( 0.05 ) so the hypothesis is accepted. It concluded that students  understanding of mathematical concepts by applying methods PQ4R better than students comprehention of mathematical concepts with conventional learning with 95% confidence level .
