Mathematical ability of students creative thinking is a component that must be mastered by the student. Mathematical creative thinking plays an important role, both in solving the problem and well, even in high school students. Therefore, efforts are needed to convey ideas in mathematics. But the reality is not yet developed the ability to implement a learning model that is expected to help improve Knowledge-Based Knowledge Management (KBKM) students in mathematics. This research applies the model Numbered Heads Together (NHT) as an alternative to learning that is expected to enhance these capabilities. The research method was quasi-experimental with pretest and Posttest Control Group Design. The sample in this research is 130 eighth grader students of two school in Ambon. Each school represents high school rank and medium school rank. Each represents a high school rank and rank schools being. The hypothesis was tested at the 5% significance level. Analysis of the data by finding the mean, standard simpagan and n-Gain. From the analysis of the data found that: (1) increase KBKM students in the experimental class and control class; and (2) Learning with NHT better than Conventional method.
