Introduction. The relevance of the problem presented in the article is due to the need of modern society for an environmentally oriented person and the real situation with the study of natural disciplines in educational institutions.Of particular importance in solving this problem is the formation of creative natural science skills among students in the conditions of additional biological education within the framework of a bioeco-oriented educational environment. In this regard, a pedagogical analysis of domestic and foreign works on the study of the content of the main concepts on the research problem was carried out, which showed that such concepts as "creative natural science skills" and "bio-eco-oriented educational environment" were defined for the first time and introduced into pedagogical science; a typology of natural science skills has been developed. A study on the formation of creative natural science skills in students in the conditions of additional biological education has not been previously conducted. The purpose of the article is to identify the components, their content, the influence of this environment on the success of the formation of creative natural science skills of students in the system of additional education, to analyze the results of the pedagogical experiment.Materials and Methods. The leading methodological approach in solving the research problem is the environmental approach. In the process of work, theoretical (analysis of environmental, psychological and pedagogical literature, regulatory documents on the education and upbringing of an environmentally literate person; generalization, systematization, study of the pedagogical experience of teachers of additional education, modeling) and empirical (open observation, questioning, interviewing, conversation, testing , own observations of the authors, quantitative and qualitative analysis of the obtained data) research methods were used.Results. The result of the study was the author's interpretation of the key concepts of "creative natural science skills", considered in a two-vector perspective - creative and natural science; "bioeco-oriented educational environment" consisting of subject, information and creative components. The authors of the article analyzed the feasibility of creating a bioeco-oriented educational environment as a condition for the formation of these skills and empirically proved the effectiveness of its functioning. This environment includes a triad: subject, information and creative components, the functioning of which allows you to effectively influence the process of formation of an environmentally oriented personality and creative natural science skills. The results of the experimental work carried out at the Children's Ecological Center of Chelyabinsk testify to the effectiveness of the functioning of the created educational environment in terms of the formation of the studied skills.Discussion and Conclusions. Experimentally, the positive impact of the bioeco-oriented educational environment created at the Children's Ecological Center of Chelyabinsk on the process of forming students' creative natural-science skills was proved, which gives grounds to state the expediency of creating such an environment in organizations of additional biological education. In the course of the study, it was revealed that the information component of a bio-eco-oriented environment, which includes the author's program "A Fascinating World in the Eyepiece", is the most effective form of forming a harmoniously developed, creative personality. The next step of the research is the development of a professional development program for teachers of additional education and teachers of the natural science orientation of general education schools on the formation of creative natural science skills in students as the basis for the formation of an environmentally literate personality.
