Abstract
This study aims to: 1) Find effective devices in mathematics learning developed based on the PBM model; 2) Finding improvement in students mathematical communication ability using learning tools based on PBM model; 3) Finding an increase in students mathematical dispositions using learning tools based on the PBM model; 4) Finding student responses to learning devices developed based on the PBM model; 5) Finding the process of answers made by students in solving students mathematical communication questions. This research is a development research using the development model of Thiagarajan, Semmel and Semmel (4D). The first trial was conducted in class XI TKJ-1 and the second trial was conducted in class XI TKJ-2 SMK Tritech Informatika Medan. The results of the first trial and trial II were obtained: 1) learning devices fulfilled effectiveness, effective in terms of a) classical learning completeness of students; b) achievement of learning objectives; and c) learning time; 2) improvement of students mathematical communication ability using learning tools based on the PBM model, in the first trial 73.83, and increased in the second trial 86.67; 3) achievement in the position of students in trial I 69.5 increased 74.17; 4) student responses to the components of the learning device and learning activities are positive; 5) the process of answering students in trial II is better than trial I.
