This research aims at investigating the effectiveness of Problem Based Learning with Fishbone Diagram on the students’ critical thinking skill in the Biology learning. This research adopted a quasi-experimental design notably pretest-posttest nonequivalent control group design. Population of this research included 73 students of grade X of the State Senior High School 1 of Pundong. The population was taken by using target population, and 49 students were determined as the sample by using random sampling technique. This research adopted critical thinking tests that were administered before and after the learning process took place. The instrument to measure critical thinking skill was a test consisting of 11 items. The instrument was initially validated the expert lecturer (expert judgment) to obtain its content validity and construct validity. Subsequently, empirical validity and instrument reliability were done by using Alpha Cronbach. The data of critical thinking skill were analyzed by using independent sample t-test at the significance level of (α) = 0.05. The result showed the significance value of 0.00<0.05. This study suggests that PBL with FD was effective in developing the students’ critical thinking skill.
