The research is motivated by the student accept what the teacher, students are not accustomed to thinking to find concepts learned, students easily forget the material being studied and the results of students mathematics learning low. The purpose of this research to know whether there is any effect of applying the model of Problem Based Learning (PBL) with College Ball to learning mathematics, to know how the attitudes and skills of VIII class students of SMP Negeri 3 Batang Kapas. The study was pre-experimental research design with pre-test and post-test. Sampling technique was done randomly, selected as the experimental class VIIIB class. Is a research instrument test with used is test t, observation sheets attitudes and skills. Based on the calculations obtained tcount= 18.42, more than t(α/2) = 2.05, with α = 0.05, then the hypothesis is accepted. It can be concluded that there is a model application of Problem Based Learning (PBL) is accompanied mathematics. Attitudes and skills after execution models poblem Based Learning (PBL) with the College Ball, the better.
