Formulation of Teaching Materials for Environmental Pollution Based on Hybrid Learning to Develop Student Environmental Literacy

<p>Environmental literacy is a learning approach that utilizes the environment as a learning resource. This approach connects the environment in teaching and learning activities where the environment acts as a learning resource. Based on the results of the analysis in previous research, the researcher knows that the condition of the ability or literacy level of the student's environment is still classified as medium and low. There is still a low and moderate level of student environmental literacy, so efforts are needed to develop environmental literacy. Researchers assume that the development of these abilities can be built with teaching materials based on environmental literacy. This teaching material is used in Hybrid environmental pollution courses using MOLS (Mulawarman Online Learning System). This research is a type of development research with the ADDIE procedure or model (Analysis, Design, Development, Implementation, and Evaluation). This research was conducted at FKIP Mulawarman University for approximately 7 months. Starting from conducting environmental literacy tests to developing teaching materials in the environmental literacy domain. Based on the results of the material expert validation it is known that teaching materials get a feasibility score of 92.10%, and from the validation results the media experts get a score93.75%. So it can be concluded that the teaching materials developed in the domain of environmental literacy are very worth it to be used as a learning media.</p><p><strong>Keywords: </strong>Hybrid Teaching Materials, Environmental Pollution, Environmental Literacy, the ADDIE model.</p>
