This research aims to describe the application of Padlet learning media in improving students' mathematics activities and learning outcomes in mathematics induction material for the 2022/2023 academic year. This type of research is classroom action research. The classroom action research design used in this research is a model developed by Kemmis and Mc Taggart. The research was carried out in 2 cycles, the first cycle consisting of 2 meetings and the second cycle consisting of 2 meetings. Researchers collected data by observation and tests. The subjects in this research were 33 class XI-MIPA 2 students at SMAN Bandarkedungmulyo, consisting of 11 male students and 22 female students for the 2022/2023 academic year. Based on the results of research in Cycles I and II, it was seen that student activity increased from 62% with fairly good criteria in cycle I to 86% with very good criteria in cycle II and the average student learning achievement test was 48.75 with a classical percentage of 21 % in cycle I was 80.71 with a classical percentage of 78% in cycle II. In Cycle II, student activities have reached the success criteria and student results have reached ≥76% classically, so by implementing Padlet learning media you can increase student activity and student learning outcomes.
