This research is classroom action research with two cycles including planning, implementation, observation and reflection. The success of the action is marked by improved of the learning process and increase of achivement. Improvement of the learning process can be seen from the reflection of observations result and increased of achievement marked by value of student's individual progress and reaching of KKM score. The results of research showed activity of teacher and students improved after doing an action. Number of students who reach a score of KKM on UH in the end of each cycle increase compared to the number of students who reach a score of KKM on base score and the number of students who get value of individual progress 20 and 30 more than the number of students who get value of individual progress 5 and 10. The results of this research show that apply of cooperative learning model structural approach of NHT make a change in the learning process and increased students achivement of math at class X GB-1 SMKN2 Pekanbaru. Based on these results, apply of cooperative learning model structural approach of NHT can improve achivement of students math.en-USnumbered heads togethercooperative learningachivementstudent Paper Post Degree
