Informed decision-making requires a certain level of scientific knowledge on health, environment or technology. Hence another goal for STEM education presents itself; it is to increase STEM literacy. It can be defined as the knowledge and understanding of scientific and mathematical concepts and processes that are needed for individual decision making, participating in civil and cultural affairs, and for economic productivity for all students (NRC,2011). STEM literacy refers to (1) obtain scientific, technological, engineering and mathematical knowledge and using it to identify issues, get new knowledge, and use it for issues about STEM, (2) comprehend the characteristics of STEM disciplines as forms of human efforts including inquiry, design, and analysis processes, (3) understand how STEM disciplines give shape to our material, intellectual and cultural world, and (4) engage in issues about STEM by using ideas related to science, technology, engineering, and mathematics as thoughtful, sentimental and contributed citizens (Bybee, 2010).
