The advent of the fourth industrial revolution has precipitated a significant transformation in engineering education, necessitating the development of novel professions. Given the circumstances, the active learning technique seems to be particularly crucial at this time. Active Learning is an educational method that places the student at the center of the learning process, actively including them in the learning experience. It involves empowering students to take on the central role in the learning process by engaging in meaningful activities and engaging in critical thinking about their actions. This strategy can be highly significant in enhancing students' comprehension of complex concepts incorporated in an engineering curriculum. This article showcases the implementation of the approach inside the framework of a machine design course. Under the guidance of their lecturers, the students utilized specialized laboratory equipment and self-made devices and specimen to observe the concentration of stresses in loaded machine components and assess their impact. The advantages of this learning strategy were significant, encompassing enhanced critical thinking abilities, heightened retention and application of new information, increased motivation, improved interpersonal skills, and ultimately led to improved performance in final tests.
