The method used in this research is research and development (R&D) method. The model used in this study refers to Research and Development by Sugiyono. The data sources of this research are linguist validators and material experts. The research instruments used were interview guidelines, linguist validation questionnaires and material expert validation questionnaires. The process of developing student worksheets based on the surrounding environment as a learning resource through 4 stages, namely potential and problems, data collection, product design, and product validation. The level of validation is based on the experts. The linguist obtained an average score of 3,4 with very valid criteria and the percentage value obtained 85% with very feasible information, the material expert obtained an average score of 3,69 with very valid criteria and the percentage result obtained 92,3% with very feasible information.
