The rapid pace of societal advancement necessitates a robust educational foundation to ensure individuals can effectively navigate and contribute to contemporary developments with their skill sets. Education plays a pivotal role in human development, influenced by a range of internal and external factors, all of which are crucial considerations for optimizing the human development process. Quality education is characterized by its ability to impart critical thinking skills and foster a motivation to learn among its students. STEM (Science, Technology, Engineering, and Mathematics) represents a pedagogical model that supports the cultivation of these skills and motivations. By integrating multiple disciplines into a cohesive framework, STEM aims to produce graduates who are competent and equipped for the challenges of the modern world. This literature review provides a systematic examination and discussion of the theoretical and conceptual underpinnings of STEM, critical thinking skills, and learner motivation. The evidence suggests that STEM is highly effective in enhancing students' critical thinking abilities and their eagerness to engage in learning, thus establishing it as a valuable educational approach.
