The problem of this research is the low critical thinking ability in mathematics of
grade III students at SDN 5 Metro Pusat. The purpose of this research is to
describe and analyze the influence of the problem based learning model on critical
thinking skills in mathematics learning. This type of research is quantitative

research with an experimental approach. The research design used is non-
equivalent control group design. The research population consisted of 54 students.

The research sampling technique used non probability sampling. The sample in
this research consisted of 54 students. Data collection techniques using test and
non-test techniques. The data were tested for hypotheses using a simple regression
test. The results of this research prove that there is an influence of the problem
based learning model on critical thinking skills in mathematics learning of grade
III students.
Keywords: problem based learning, critical thinking skills, students}
