The term philosophy of science demonstrates a coherent system of ideas and theories that find its place in the natural sciences, philosophy, and humanities. This means that the main content of the philosophy of science includes a structured approach to the understanding of science, its techniques and strategies. The philosophy of science deals with the principles, subjects, methods, laws, and results of science, and examines them critically, analyzing their logical assets, their objectivity, their proximity to the truth and the degree of certainty. Some thinkers have argued that the philosophy of science is the same science, principles, theories, and theories derived from science and their relationship to each other.
The teachers' perceptions of scientific knowledge, its limits and its potential determine the logic and the image of their mental and cognitive activity during the teaching and learning of science and define the nature, form, and style of experiences and activities proposed for teaching and learning science. Moreover, the failure to establish clear relationships between the science teacher's understanding of science and the ability to use science processes and the implicit philosophy of science form the basis upon which scientific decisions are based. This results from uncertainty about what science is, what its content is, what processes it involves, and how it interacts with the ideas and perceptions of science teachers.
