Abstract
This study was conducted to examine the effect of STEM-integrated Problem Based
Learning learning model in improving the biological literacy skills of class X students of SMA Negeri
1 Samarinda. This study was designed to test the effect of independent variables (X) on the dependent
variable (Y) with quantitative methods and quasi-experiment design with Pretest-Posttest Control
Group. Group random sampling method to select class X-7 as the experimental group and class X-9 as
the control group. Data were analyzed using the Independent Samples t test with a significance level
of 5%. The application of PBL STEM brings better learning outcomes, as evidenced by data analysis
significantly improves students' biological literacy skills. This is evidenced by the significance value
of the t test which is smaller than 0.05, namely 0.036. Through the N Gain Test, it was revealed that
the increase in learning outcomes was striking, reaching 0.74 and falling into the high category,
