This research aimed to determine the effect of Problem Based Learning (PBL) model on
students’ problem solving abilities and cognitive learning outcomes elaborating an experimental research
design. The research data was collected through a pre-test and post-test using a rubric to determine the
students’ problem solving abilities and cognitive learning outcomes. The results showed that PBL
model significantly improved problem solving abilities and cognitive learning outcomes of students by
17.73% and 23.65%, respectively. . Based on these results, the researchers suggested that teachers use
the model of Problem Based Learning (PBL) consistently because it has proven its success on the
ability to solve problems and cognitive achievement of students.

Key Words: problem based learning, problem solving abilities, students achievement of cognitive
