The Sustainable Development Goals (SDGs), also known as The Global Goals, are a collection of 17 global goals that aimed to achieve a better and more sustainable future for all. One of 17 goals in SDGs is “Quality Education (4th Goal)”. Achieving inclusive and quality education, especially in science education, is one of the most powerful and proven vehicles for creating sustainable development. The International Seminar on Science Education (ISSE) is the major opportunity each year to discuss the interaction among education sciences in developing areas for sustainable development within Chemistry, Physics, Biology and Natural Science areas. It provides a platform for international education practitioners, teaching staff, researchers, and other stakeholders learning the major science education trends for achieving quality science education. Therefore, the seminar intent to keep abreast of the current development and innovation in science education area as well as providing an engaging platform for participant to share knowledge and expertise in related disciplines.

This proceedings is the regular edition of the conference proceedings of the 6th International Seminar on Science Education (6th ISSE 2020) (held by the Graduate School of Chemistry, Physics, Biology, and Science Education Yogyakarta State University, Indonesia on November 28th - 29th 2020. The conference was conducted by online (virtual conference). The scope of our seminar that will be discussed is topic areas within Chemistry, Physics, Biology, and Natural Science education. There are 130 papers that have been carefully peer reviewed. All papers in this proceeding were obtained from a selection process by a team of reviewers and had already been presented in the conference. This seminar has four keynote speakers who are Prof. Dr. Ingo Eilks (University Of Bremen, Germany), Prof. Dr. Lilia Halim (Universitas Kebangsaan Malaysia, Malaysia), Prof. Russell Tytler (Deakin University, Australia) and Dr. Peta White (Deakin University, Australia).

The success of the ISSE 2020 conference series, because of the support of many people i.e. Steering Committee, Program Committee, Organizing Committee, authors, presenters, participants, keynote speakers, student committee, and people in other various roles. We would like to thank them all. Finally, we would also like to thank Atlantis Press for their support in publishing the 6th ISSE 2020 conference proceedings and this proceeding hopefully may contribute to all research education.
