Abstract:
The problem in the research was the low achievement of students in studying IPA in
IVB class of Elementary School 161 Pekanbaru, with an average score was 69,34 in
daily tests. Learning outcomes of students as low as stiil below the standards set by
the school KKM was 75. The low yield due to student learning used by teacher quite
right and was not in accordance with the characteristics of learning IPA; they are
the real experience and discovery. Based on the problems it was necessary to fint the
solution that was solving by applying Problem Based Learning model. The study
aims to improve student learning outcomes of IPA in IVB class of Elementary School
161 Pekanbaru. The research in the form of class research. The subjects were IVB
garders totaling 38 students, which consisted of 16 male students and 22 female
students. The results showed that by applying the Problem Based Learning model
could improve science learning outcomes of students, on the basis of the average
score of the students was 69,34 increase at UH I to 75,37, an increase from previous
test scores by 8,69%. UH II on the average value of student learning outcomes to be
