Abstract
The purpose of this research is to know the difference of mathematical representation skill, the result of science
learning and its influence on problem-based learning and discovery learning model. The population of this study
was 16 students of PGSD FKIP University of Lampung. Among 534 students, there were two experimental classes consisting of 35 students and each was determined through cluster random sampling. The data on mathematical representation skills and learning outcomes of science were obtained through a description test, five questions
for assessing mathematical representation skills, and ten questions for assessing science learning outcomes. From
the instruments that had been tested to 30 respondents, it was obtained a valid and reliable instrument with a
score of 0.505 for mathematical representation skills, and 0.832 for learning outcomes. Furthermore, the data
were analyzed by using normality test, homogeneity test, independent sample t-test, correlation test, and simple
linear regression test. The results showed that there was no difference in the result of mathematical representation
skill and science learning outcomes, between the problem-based learning model and real discovery. But there is a
positive and significant linear influence between the mathematical representation skill and the learning outcomes
of science, through a problem-based learning model of discovery
