STEM Education

STEM education is an innovative educational approach that integrates science, technology, engineering, and mathematics. Its goal is to prepare students for careers related to these fields and to successfully face the social and economic challenges of the 21st century.

STEM Students

STEM students may face various difficulties depending on their level and experience, but some are common: limited understanding of basic concepts, difficulty applying abstract ideas to the real world, lack of critical thinking, low motivation, and little practice.

STEM Teachers

Being a STEM teacher is a significant challenge, as it requires not only highly specialized technical knowledge but also strong pedagogical and communication skills to convey these complex concepts clearly, engagingly, and effectively.
