STEM education, which consists of the initials of the words Science, Technology, Engineering and Mathematics, is an educational approach that blends theoretical knowledge with engineering skills. The STEM education approach is implemented in the USA from preschool to senior high school through engineering design and interdisciplinary studies within the framework of the Next Generation Science Standards. The aim of this research is to determine the effect of STEM applications in preschool education on students' career goals and engineering perceptions. The case study, one of the qualitative research models, was used as the research model. The research was carried out for 12 h in 8 weeks with the participation of a total of 20 students, nine boys and 11 girls, in the preschool age group of five. Career Goal Setting Form was used as a data collection tool. As a result, it has been concluded that STEM applications in preschool education are effective on students' career planning. STEM applications have increased students' interest in STEM fields. STEM applications have given students new knowledge about the engineering profession and skills. STEM applications have been effective on students' product design/invention goal process.

STEM教育由Science、Technology、Engineering和Mathematics三个词的首字母组成，是一种将理论知识与工程技能相结合的教育方法。通过在下一代科学标准框架内的工程设计和跨学科研究，美国从学前班到高中实施了 STEM 教育方法。本研究的目的是确定学前教育中 STEM 应用对学生职业目标和工程认知的影响。案例研究是定性研究模型之一，被用作研究模型。该研究在 8 周内进行了 12 小时，共有 20 名学生参与，其中 9 名男孩和 11 名女孩，在 5 岁学龄前组。职业目标设定表被用作数据收集工具。因此，得出的结论是，学前教育中的 STEM 应用对学生的职业规划是有效的。STEM 应用增加了学生对 STEM 领域的兴趣。STEM 应用为学生提供了有关工程专业和技能的新知识。STEM 应用程序对学生的产品设计/发明目标过程非常有效。
