The creativity of high school students in Indonesia has not met the demands of 21st century because in general the students' thinking ability has not reached high-level thinking ability. The objectives of this study are: first, utilizing android technology to develop an Analogipedia module containing ecosystem teaching materials for high school students, and second, testing the effectiveness of using analogipedia module in improving students' creativity. This research is development research. To measure the effectiveness of the product (module) in improving students' creativity, nonrandomized subject research design, pretest-posttest control-group design was employed. The study involved 88 high school students as the experimental class and 87 students as the control class. The data were collected using questionnaires and open-ended questions. The results show that: first, the experts on materials and teaching; peer reviewers; and biology teachers assess that analogipedia module belong to a very good category. In addition, students assess that the module is classified in a good category. Second, the score of students' creativity that utilizes analogipedia module is different from the score of the students that uses student's worksheet. This is indicated by the t-test showing the significance level of 0.043, which means that the analogipedia module is effective to improve the creativity of high school students. Different results are also indicated by the increase of creativity test score in which the experimental class reaches 96.48% and the control class is 85.24%. The contribution of this research is to enrich android-based learning media. The analogipedia module can be used in all biology subjects for ecosystem materials, especially at the high school level through the application on the Playstore.
