- Problem Based Learning Model, mathematical communication skills, development of learning devices, and 4-D models.
- This study aims to: 1) Find effective tools in mathematics learning that are developed based on the PBM model; 2) Finding an increase in students' mathematical communication skills by using learning tools based on the PBM model; 3) Finding students' responses to learning tools developed based on the PBM model. This research is a development study using the Thiagarajan, Semmel and Semmel (4D) development models. Trials of learning tools based on the PBM model were carried out twice to obtain quality equipment. The first trial (trial I) was conducted in class XI TKJ-1 and the second trial (trial II) was conducted in class XI TKJ-2 SMK Tritech Informatika Medan. The results of the research trials I and trial II obtained: 1) learning devices meet the effectiveness, effective in terms of a) classical student learning completeness; b) achievement of learning objectives; and c) learning time; 2) improvement of students' mathematical communication skills by using learning tools based on PBM models, in the first trial I got an average posttest 73.83, and increased in the second trial with an average posttest value of 86.67; 3) students' responses to the components of the learning tools and learning activities are positive.
