This research based on the student comprehension of mathematical concept still lower. This matter seen at result learn class student mathematics of IX SMPN 2 Bayang School Year 2014 / 2015. This type of this research is experiment. Research with random sampling techniques. Population in this research is all class student of IX SMPN 2 Bayang school year 2014 /2015. The selected class of sampel is IX2 as experiment class and of IX4 as control class. Instrument used in this research is the tes of understanding of mathematical concept. Form of tes the used is form of essay with reliabilitas test is r11 = 0,924. Technique analys data used in this test is t. According to result of data analysis known that both class of sampel have normal distribution and is homogeneous at real level = 0,05. Result of hypothesis test obtained by t =3,06 and ttable=1,67 hence hypothesis at this research is accepted. So that can be concluded that student understanding of mathematical concept by applying study is Cooperative Type Numbered Heads better than student understanding of mathematical concept with conventional study in class of IX SMPN 2 Bayang.
