In this article, I intend to approach STEM Education (Science, Technology, Engineering, and Mathematics), which can make a significant contribution to the formation and development of conscious attitudes from the preschool period. Understanding that each person is unique and has an individual rhythm of psycho-physical development is essential in creating a diversified and adaptive educational environment tailored to the individual needs of children. Through STEM Education, children can develop attitudes such as curiosity, perseverance, critical thinking, and confidence in their own abilities. They learn to approach challenges as learning opportunities and to find innovative solutions. Additionally, collaboration and communication skills are developed as they learn to work in teams and express their ideas and opinions. One of the important aspects of STEM Education in the preschool period is the individualized approach to the learning process. Each child has their own pace of development and distinct interests. Therefore, it is important for educators to be aware of these differences and provide activities and challenges that are appropriate to the child's level of development.
