<![CDATA[This study aims to develop Student Worksheets (LKPD) based on Problem Based Learning (PBL) on Diversity material to improve cognitive learning outcomes and tolerance attitude profiles in Pancasila Education subjects in grade IV Elementary Schools. The research method used is Research and Development (R&D) with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). Data were collected through interviews, questionnaires, observations, and learning outcome tests. The research instruments included expert validation sheets, student response questionnaires, tolerance attitude questionnaires, and cognitive test questions. Data were analyzed qualitatively and quantitatively. The results showed that the PBL-based LKPD developed had characteristics that were in accordance with the PBL model syntax, met the eligibility criteria from material, language, and graphic experts, and received positive responses from teachers and students. The use of this LKPD was also proven to improve students' cognitive learning outcomes, with N-Gain values showing a medium to high category. Students' tolerance attitude profiles also experienced a decrease after using PBL-based LKPD. This study concludes that PBL-based student worksheets (LKPD) are effective in improving students' cognitive learning outcomes and tolerance profiles on the subject of diversity. These LKPDs can be an innovative and relevant alternative teaching material for Pancasila education in elementary schools.]]>
