This research based on community service aims to evaluate the effectiveness of the science, technology, engineering, and mathematics (STEM) approach in strengthening the literacy and numeracy learning profile of students at Eakkapapsasanawich Islamic School Thailand. The research employs a quantitative research approach with a single-group pre-test and post-test control design. The research sample consists of two groups: an experimental group receiving STEM-based instruction and a control group receiving conventional instruction. The total number of students involved in this study is 60, with each group comprising 30 students. Data collection techniques include pre-test and post-test assessments involving literacy and numeracy-related questions relevant to the school curriculum. Data analysis is conducted using descriptive statistical methods and independent t-test to compare test results between the experimental and control groups. The results indicate that students who received instruction with the STEM approach experienced a significant improvement in numeracy literacy compared to those who received conventional instruction. The average scores of the final test in the experimental group were significantly higher than those in the control group. Statistical analysis also reveals a significant difference between the two groups in terms of improvement in numeracy literacy scores. This suggests that the STEM approach is effective in enhancing the literacy and numeracy learning profile of students.
