Science literacy is an important competency that needs to be developed in elementary school students. However, based on the results of observations, it shows that students' ability in food chain materials at MI Nurul Hasan Singgahan Ponorogo is still relatively low. This research aims to develop and test the feasibility, practicality, and effectiveness of the Chain Education application, which is an Android-based learning application that applies the Contextual Teaching and Learning (CTL) approach. The research used the Research and Development (R&D) method with the ADDIE model involving 29 students in class V. Data were collected through observation, interviews, expert validation, questionnaires, and tests, then analyzed descriptively using paired sample t-test and N-Gain tests. The results of the study showed that the application obtained a validation score of 93.75% of material experts, 95.40% of media experts, and 95.44% of student responses in the category of very practical. In addition, the average score of students increased from 55.17 to 92.41 with an N-Gain of 0.8789 (high category). These findings show that the CTL-based Chain Education application is feasible, practical, and effective in improving the science literacy of elementary school students.
