### Abstract

*Abstract*

*The learning achievement of Mathematic in Senior High School 01 of Kotanopan was not as expected. Methods and models learning which were used in the teaching learning process yet increased the achievement of the student in mathematics. So that, its necessary rat to improve the achievement of the student in mathematics by using inquiry learning. This study has purpose to measure the effect inquiry learning toward the achievement of the students in mathematics specially in Senior High School 01 of Kotanopan. Population of study were all the students X level Senior High School 01 of Kotanopan which has 155 students in number. The sample were selected by using random sampling technique. The chosen sample is X ^{A} which use as an experiment class and have 30 students and X^{D} as a control class numbered 30 students also. This study is quasi experiment.
