One of the key elements of science education and teaching is to accurately determine the nature and characteristics of science. Determinations about the nature of science affect science education methods in many ways. Those involved in science education and science teaching agree that the nature of science should be taught explicitly. Thomas Kuhn's theses (paradigm, normal science, scientific revolutions, incommensurability, puzzle solving, theory choice, discovery and justification distinction) on the structure and nature of science, which he put forward as a (...) result of his studies including the history of science, philosophy of science and sociology of science, have been frequently referenced sources in the field of science education and teaching. Accordingly, in the article, the claim of the logical positivist understanding of science is discussed within the framework of Kuhn's views, with the thought that it does not reflect the nature of science. The main argument of the article is that Kuhn's determinations on science and the nature of science emphasize the developing, transforming and changing structure of science and thus he transforms the understanding of the nature of science that is often used in science education.

French scientist Henri Poincaré is one of the leading thinkers in the field of philosophy of science with his determinations on science and scientific activity. Poincare's understanding of science is expressed as conventionalist because he asserts that all sciences, including mathematics, consist of conventions and definitions. In this article, Poincare's views on how scientists should evaluate the data obtained from observation and experiment in their studies and the hypotheses that describe the relationships between these data are discussed. In the article, (...) it is also thought that especially Poincare's claims about the structure of science and the nature of scientific activity are important in terms of understanding some scientific views that emerged in the second half of the twentieth century.
