<![CDATA[This study aims to produce an e-science magazine as a valid, practical, and effective science learning medium for eighth-grade junior high school students. This study was conducted based on the analysis of the problems that have been carried out, namely teachers still use conventional media that is not electronic, teachers use media only on certain materials, and there are materials that are difficult for students to understand, namely the human digestive system. So it is necessary to innovate technology-based learning media that not only contain text, but also images, videos, audio and more colorful media displays that can improve understanding, motivation and improve student learning outcomes. This research is a type of development research or Research and Development (R&D), namely a research method that aims to produce a product and test its effectiveness. The development model applied is the 4D model consisting of four main stages, namely Define, Design, Develop and Disseminate. Data were collected through interview sheet instruments, validation questionnaires, practicality questionnaires and test instruments in the form of multiple-choice questions. The validation results obtained a score of 4,68, indicating very valid. Teacher practicality achieved a practicality percentage of 97,33%, indicating very practical, and student practicality achieved a practicality percentage of 97,47%. The effectiveness test, which was assessed based on the improvement in student learning outcomes analyzed using n-gain, obtained a gain score of 0,80, representing a high criterion. The classical learning completion analysis obtained a score of 100%. Based on these results, the e-science magazine media as a science learning medium is highly valid, very practical, and very effective for use in the learning process.]]>
