Elementary school teachers have a very small amount of science content to be taught during the pre-service teacher education compared to the secondary science teachers. In particular, knowledge of the wide range of conceptual hierarchies and wide breadth of biology is even more inadequate than that of secondary school teachers. Most of the elementary school teachers have taken the field of humanities and social sciences in high school selection curriculum and rarely learned about the evolutionary contents which is the core of modern biology. Recently, science education trends are strengthening the explanation system centered on evolution, so it is necessary to learn evolution related contents for elementary school teachers and elementary school teachers. In particular, evolutionary education and research are needed at the present time to strengthen research and presentations that deny evolutionary theory in research groups claiming intelligent design theory. In this study, an explanation system for evolution, which is essential for understanding the nature of life sciences was constructed. And the role of guidance on the evolutionary contents to be learned in secondary science was explored.
