—In order to promote STEM (Science, Technology,
Engineering, and Mathematics) education through
developing a professional development model, this study
seeks to identify science teachers’ perceptions regarding
STEM education and its interdisciplinary nature, and to
identify the factors that facilitate and hinder such a form of
instruction in their schools. Being one of the first studies of
STEM education in Saudi Arabia, this study elicits science
teachers’ perceptions through the use of qualitative
methodologies. The instruments include focus groups,
teacher-reflection and an interview protocol. The study ends
with recommendations that could lead to develop a
professional development model of what science teachers
need in terms of pedagogical content knowledge to enact
STEM education in class.
