摘要：This research is aimed to get information about: (1) the effect of PBL on science process skills; (2) the effect of PBL on the result of cognitive-learning of science and (3) the effect of PBL on science process skill and the result of cognitive-learning of science. This is quasi experiment research employing a pretest-posttest control group design. The research population consisted of five-graders of all elementary schools located in Group 3 of Kotagede in the academic year of 2014/2015. The sample was collected using the cluster random sampling technique. The data were analyzed using the independent t-test, the MANOVA, and Bonferroni criterion. The result of this research informs that: (1) PBL improved positively and significantly the science process skills; (2) PBL improved positively and significantly science learning result; (3) PBL improved positively and significantly the science process skills and science learning result. The skills of science process and cognitive result of learning of science of the experiment class 1 and 2 are higher than that of the control class. The whole tests and gained results show that PBL positively and significantly improves the skills of science process and the cognitive result of science learning.
