Abstract

This study aims to determine the effect of implementing a STEM-based (Science, Technology, Engineering, and Mathematics) diesel engine practicum worksheet on the Higher-Order Thinking Skills (HOTS) of students at the State University of Surabaya. The study employed a quantitative approach with a one-group pre-test/post-test design. The sample consisted of 10 students from the PTM A class (Class of 2024, 4th semester), selected using purposive sampling. Data collection techniques included a HOTS essay test and a student response questionnaire. The pre-test score (58.90) increased to 84.90 in the post-test. The Wilcoxon test yielded a significance value of 0.005 (<0.05), indicating that the implementation of the STEM worksheet had a significant effect on HOTS. The N-Gain score was 0.60 (60.02%), falling into the medium category, and the student response rate was 86.50% (very positive). The findings indicate that the STEM-based worksheet assisted students in analyzing practicum data through observation tables, calculation formulas, and analytical questions.
