This study aims to develop interactive digital Student Worksheets (LKPD) based on Contextual Teaching and Learning (CTL) assisted by the MindMeister application. This innovation is expected to improve students' mathematical collaboration and communication skills. The use of CTL in LKPD is designed to link learning to real-life situations so that the material becomes more relevant and easier to understand. Meanwhile, the MindMeister application allows students to visualize mathematical ideas and concepts collaboratively through digital concept maps. The research method used is design research with the Ploom and Gravemeijer development model. The instruments include expert validation, practicality testing through direct observation of students' mathematical collaboration and communication activities. The subjects of this study were grade VIII students of SMPN 26 Padang. The assessment stage is the trial stage of the interactive digital LKPD that has been validated and revised. Furthermore, to find out whether the product is in accordance with expectations, an analysis of practicality and effectiveness is carried out at the small group stage. The results of the study indicate that interactive digital LKPD based on CTL with the help of MindMeister is valid and practical for use in mathematics learning. In addition, the implementation of this digital LKPD is effective in improving students' mathematical collaboration and communication skills. Students are more active in group discussions, sharing ideas, and compiling problem solutions together. Thus, this innovation offers a more interactive learning approach in improving students' mathematical collaboration and communication. © 2026 Author(s).
