The purpose of this research is to find out the effectiveness of Problem Based Learning (PBL) model on sub material about abnormality and disease of human blood circulation system to the eleventh year IPA student (Class XI IPA) of SMA Negeri 6 Pontianak. The method used in this research is pre experimental design (quasy experimental) namely control group pre-test post-test design. The sampling strategy to be used in this research is cluster sampling, that is all of the population used as sample. The sample of this research consists of two classes, class XI IPA 1 experimental group and class XI IPA 2 as control group. Based on the result of data analysis, the students average score that learnt by using Problem-Based Learning (PBL) model (26,02) is higher than conventional model (19,23). From U Mann Whitney test showed Zvalue = -3,54 meanwhile Ztable = -1,96, this means there is a significant difference between the students average score of experimental group and control group on the level 5%. The score of effect size is 1,04 or can be categorized high, and if it is viewed from the normal graph standard, therefore the teaching learning process through Problem-Based learning (PBL) model gives contribution 35,08% on the students achievement.
