Abstract

The development of technology in the industrial revolution 4.0 era demands an increase in the quality of science education, especially in developing students' scientific literacy. This study aims to develop student worksheets (LKPD) based on science, technology, engineering, and mathematics (STEM) to improve students' scientific literacy in physics learning. The research method uses research and development with the analysis, design, development, implementation, evaluation (ADDIE) model. The subjects of the study were students of class XI IPA SMAN 4 Kota Langsa in the 2024/2025 academic year. The research instruments included material and media expert validation sheets, student response questionnaires, and science literacy tests. The results showed that the STEM-based LKPD developed was valid with a material expert validation score of 4.2 (very valid) and a media expert of 4.3 (very valid). The implementation of STEM-based LKPD increased students' scientific literacy with an N-gain of 0.73 (high). Student responses to LKPD showed a very positive category with a percentage of 82.6%. Based on the research results, STEM-based LKPD has proven effective in integrating science concepts with technology, engineering, and mathematics applications that are relevant to the needs of the 21st century

Abstract

Students' critical thinking skills at school have not improved. This study aims to analyze the effectiveness of e-LKPD based on STEMEC (science, technology, engineering, mathematics, entrepreneurship, and character) in improving students' critical thinking, especially on Hooke's Law material, by utilizing the imagy tool. The research method used was an experiment with a one-group pretest-posttest design involving 34 grade XI students at SMAN 5 Banda Aceh. The results showed a significant increase in students' critical thinking after the learning intervention. The average pretest score of 38.82 increased to 80.44 on the posttest with an average N-Gain score of 0.677, indicating an increase of 67.7%. The majority of students 22 people are in the high improvement category, 9 people in the medium category, and 3 people in the low category. The STEMEC approach with imagy not only improves conceptual understanding, and critical thinking, but also helps students develop 21st century skills, including collaboration, communication, entrepreneurship and character skills. These findings prove that the implementation of STEMEC as a holistic and effective learning strategy can train students' mindset and character in improving their competence in the fields of science and technology.
