This study was conducted with students at Abulyatama Junior High School and aimed to investigate the improvement of students' scientific and numeracy literacy through the use of a STEM (Science, Technology, Engineering, and Mathematics)-based learning module. The study employed a quantitative research approach using a quasi-experimental design. The sample consisted of 24 students in the experimental class and 20 students in the control class, selected through purposive sampling. Data were collected using achievement tests and analyzed using the N-gain test and paired-samples t-test. The results revealed that the STEM-based learning module improved students' scientific and numeracy literacy, with an N-gain score of 0.67, which falls into the moderate category (moderately effective). Therefore, the STEM-based learning module can effectively enhance students' scientific literacy and numeracy literacy.
