Review of: "Development of Education for Sustainable Development Integrated Coastal Conservation Education Kit in Junior High Schools" Brian A.L. Gumiran 1 1 University of the Philippines Diliman Potential competing interests: No potential competing interests to declare. The topic and the research problem of research-based learning system design are essential, and the authors have presented a specific case of this design in the context of integrated coastal conservation in a basic education setting. However, the authors need to address a number of issues and justify and rationalize important arguments in the study. Language editing First of all, language editing and tone setting are needed to make the case of the paper stronger. Aside from some structural and writing issues pointed out by other reviewers, the paper can be edited so that it would cater to international audiences by explaining/generalizing some Indonesian-specific contexts. For example, the authors can quickly describe INA-Risk analysis and explain the meaning of some acronyms. On introduction Abrasion in the ESD curriculum The concept of abrasion is a niche topic, and part of the paper can discuss how it fits in, or what its role is in a general education for sustainability (ESD) curriculum. This is important since the ESD curriculum is still developing, and advocates are still making the case for an ESD space in the whole education curriculum, in competition with other important subjects students must learn [1] . The authors can frame their discussion by answering some questions such as: Is it aligned with an overall ESD agenda in Indonesia? How is ESD (and the abrasion topic) currently structured and taught in the country? Would teaching the topic need significant teaching time, or can it be integrated with other topics? If teaching abrasion in coastal area protection is currently not taught well or not even taught at all, they may include a short literature review on why this is so. Abrasion as a priority risk In the context of disaster risk reduction and climate change adaptation, the researchers can indicate why abrasion is a Qeios, CC-BY 4.0 · Review, January 14, 2024 Qeios ID: 5Z0N4T · https://doi.org/10.32388/5Z0N4T 1/4
