This study aims to: 1) develop learning device through problem-based learning model with adobe flash are valid, practice, and effective; 2) analyze the combinatoric ability students in class XI of MAN 2 Deli Serdang through learning device developed by problem-based learning model with adobe flash. The type of This research is development research using the development model of the Thiagarajan 4-D model. Based on the results of trial I and trial II that have met valid criteria according to experts, were tested in class XI-MIA of MAN 2 Deli Serdang. The results of the analysis of the data obtained indicate that learning device based on PBL-AAF met the criteria of practice from the implementation of the learning device can be said good, effectiveness and can improve combinatoric ability. Based on the results of the study, it was suggested that device developed trial is better than trial I and can make an effort mathematics learning using learning device based PBL-AAF. © 2020 IJSTR.
