However, the application of problem-based learning integrated STEM approach with formative assessment (PBL-STEM-FA) to overcome the weakness in students^ PSS is still limited. This study aims to investigate the effect of PBL-STEM-FA on the increase in students^ PSS in the topic of fluid static. This type of quasi-experimental research with a pretest-posttest control group design involved the research subject of class XI high school students in Malang, Indonesia. Experiment class (M = 8, F = 18) was taught with PBL-STEM-FA and Comparison class (M = 12, F = 18) was taught with PBL. Experiment class^ students make engineering products in the form of miniature boats. This study used the PSS test instrument in the form of 7 essay items with 0.799 reliability. The research data were analyzed by t-test, N-gain, and effect size. The results showed that students of PBL-STEM-FA class had significantly higher PSS than students of PBL class. The N-gain in the medium category of the Experiment class (0.405) was higher than the Comparison class (0.306). The highest increase occurred in the Useful Description indicator and subtopic hydrostatic pressure for the Experiment class- and Useful Description indicators and subtopic surface tension for Comparison class. However, the two classes had the same lowest increase, namely in the Mathematical Procedures indicators and capillaries subtopics. The value of effect size at 0.651 (medium category) implies that the implementation of PBL-STEM-AF is recommended to be carried out in the field to increase students^ PSS. It is recommended that future studies add an ^Art^ aspect to the STEM approach.
