This study aims to develop and evaluate the quality of a Student Worksheet (LKPD) based on the open-ended approach for the topic of statistics, intended for Grade VIII B students at SMP Masyithoh Kroya. The development of this learning media is designed to facilitate students’ critical thinking skills by meeting the criteria of validity, practicality, and effectiveness. The research method used is Research and Development (R&D) with the ADDIE development model, which consists of the stages: Analysis, Design, Development, Implementation, and Evaluation. The validation results indicate that the media is considered "Very Valid," with a score of 86.34% from the material expert and 84% from the media expert. The practicality of the media, based on student response questionnaires, scored 71.65%, categorized as "Practical." The effectiveness of the media was determined through test results, showing a mastery level of 96.77%, categorized as "Very Effective." Therefore, the developed open-ended LKPD is proven to be feasible for use in teaching statistics and effective in enhancing students’ critical thinking skills.
