STEM education has become one of the most rapidly growing sectors in educational reform globally. Whilst the program was successfully implemented in most countries, unfortunately the introduction in Saudi Arabia was not as successful due to a lack of clarity in the description of its meaning, purpose and framework of application. Although STEM is commonly recognized as a way of strengthening mathematics and science curricula, its exact implications are still unclear for any intervention or modification in any of the subjects related to science, mathematics, engineering and Technology, (STEM) implementation. In 2009, the Ministry of Education (MOE) introduced a new mathematics and science curriculum in a joint effort with Obeikan Research Development Company, as an adapted series of science and mathematics textbooks. The new adapted curricula attempt to make meaningful connection between student's lives and their educational experiences through the implementation of new teaching practices which include student centred investigation strategies and problem-based learning.
