:  Limitations in komputer network practicum, causing only relying on theory and tests. During the pre-test, there were 8 students whose learning outcomes had not been completed. This study aims to improve student learning outcomes using project-based learning models. The object of this research is students in the 4th semester of komputer education, FKIP, Universitas Mulawarman. The software used in making the project is a Cisco packet tracer with a choice of komputer network projects. The type of research used is classroom action research in the form of projects and tests to get maximum learning outcomes. Learning outcomes are obtained from a combination of project scores and tests from cycle I and cycle II. Based on the research results in cycle I and cycle II, it can be concluded that there is an increase in student learning outcomes through the application of project-based learning. Suggestions for research need to examine other variables such as creativity and learning activities because project-based learning requires a lot of observation of group work in monitoring. in the classroom

This study examines the effectiveness of STEM (Science, Technology, Engineering, and Mathematics) education in enhancing problem-solving skills among high school students. With the increasing demand for critical thinking and problem-solving abilities in the workforce, STEM education has become a crucial approach to preparing students for future challenges. The study aims to evaluate how project-based STEM curricula impact students' creativity, analytical skills, and overall problem-solving capabilities. Using a quasi-experimental design with a control group, the research was conducted with high school students who participated in STEM-based lessons involving the 5E instructional model. Data collection involved pre- and post-tests, classroom observations, and semi-structured interviews to measure changes in student skills. The findings indicate that students exposed to STEM education demonstrated significant improvements in problem-solving, creativity, and analytical thinking compared to their peers in traditional lecture-based classes. The study highlights the advantages of project-based learning in promoting active student engagement and fostering skills necessary for addressing real-world problems. These results suggest that STEM education can be more effective than traditional methods in cultivating essential 21st-century skills. The study recommends the broader implementation of STEM strategies in secondary education and further exploration of the long-term impact of STEM learning on various skills required in the professional world.
