In Bulgaria, teachers are trying out new STEM methods β science, technology, engineering and mathematics β to make lessons more interactive. Through semiβstructured interviews, educators shared their experiences: many value the students' excitement, but they also point out concrete obstacles. The time allocated in the curriculum is often insufficient; hours for interdisciplinary projects are cut to make room for traditional subjects. Moreover, a lack of technological resources β such as robotics kits or simulation software β limits handsβon activities. Another critical issue is training: teachers request specific professionalβdevelopment courses to better manage STEM tasks. Despite the challenges, results are encouraging: classes that integrated practical experiments recorded higher participation and curiosity. Interviewees also highlighted the importance of institutional support: school policies that promote equipment purchases and interβschool collaboration can speed up STEM adoption. In short, the study shows that, although Bulgaria still has work to do, teachers are motivated to transform education by focusing on shared resources, continuous training, and greater curricular flexibility.
International literature agrees that STEM integration requires three core pillars: interdisciplinary content, problemβbased practices, and development of transversal skills. In Bulgaria, the recent regulatory framework (National Education Strategy 2020β2030) calls for STEM modules, yet their implementation hinges on local factors. Interviewed teachers highlighted infrastructure gaps: poorly equipped labs, unstable internet connections, and lack of shared digital platforms. These limitations affect the ability to conduct coding activities, 3D printing, or advanced physics experiments. From a competency perspective, research shows teachers must possess not only subject knowledge but also pedagogical skills to facilitate active learning, collaboration, and critical reflection. Continuous training programs, often funded by EU grants, include workshops on projectβbased methodologies, use of augmentedβreality tools, and formative assessment. Another crucial aspect is assessment: traditional grading systems do not fully capture STEM competencies, prompting experiments with rubrics based on portfolios and project presentations. Finally, the study emphasizes the importance of a collaborative culture among schools, universities, and businesses: partnerships with research labs or tech startβups provide resources, mentorship, and realβworld contexts for students. When coordinated, these elements can bridge the gap between policy vision and daily practice, making STEM a stable component of the Bulgarian curriculum.
