This study aims to produce contextual e-magazine learning media for circulatory system material for class XI high school students that are valid and practical. The method in this study is to use the Plomp model development method. The development stage of this model begins with the initial investigation stage (preliminary research), the development or prototyping phase, and the assessment phase. The instruments used in this study were validity and practicality assessment sheets. Based on the results and discussions conducted, it was concluded that the contextual e-magazine based on circulatory system material for grade XI high school students developed in this study has achieved a validation value of 97.27% with very valid criteria and a practicality value of 96.64% with very practical criteria so that it is suitable for use as a biology teaching material for grade XI high school students.]]>
