The term STEM combines four different disciplines namely Science,Technology, Engineering, and Mathematics. STEM education is a concern because it isrelevant to be implemented and forms 21st century skills. This makes pre-service teacherneed to understand STEM education in order to apply it to learning correctly. There arethree aspects that influence the conception, understanding, and self-efficacy of preservice science teachers. Therefore, research was conducted with the aim of analyzingthe relationship between conception, understanding, and self-efficacy of pre-servicescience teachers towards STEM education. This study uses Quantitative DescriptiveResearch Design because it aims to describe and illustrate the relationship modelbetween conception and understanding of self-efficacy in STEM education from thepre-service of Science Education study program students, Semarang State University.Based on the research that has been conducted, a structural relationship model betweenconception and understanding of STEM education self-efficacy among pre-servicescience teachers is obtained. In the model, simultaneously the conception variable andthe understanding variable affect the STEM education self-efficacy of pre-servicescience teachers, where a higher contribution is given by the conception variable. Inconclusion, conception and understanding affect the self-efficacy of science teachercandidates in STEM education.]]>
