Abstract
STEM education is a useful tool in promoting 21st-century competencies, such as cultural awareness, critical-thinking and problem-solving skills. Having these skills prepares
students for a competitive, global marketplace. Teachers play a crucial role in providing quality STEM education, and teachers require high levels of self-efficacy and STEM pedagogical content knowledge to impart quality levels of instruction. We examined the relationship between self-efficacy and STEM pedagogical content knowledge. Results showed higher self-efficacy was related to higher STEM pedagogical content knowledge. Implications are discussed.
