Abstract
Abstract Generally, mathematical communication skills are still facing the problems. This is based on the results of the PISA study and some previous research results. The problem that occurs is that students are still not quite right in using mathematical symbols, the use of graphs and tables as well as the ability to explain arguments mathematically is still low Mathematical communication skills are needed and can be used in solving problems. Research aims to describe the improvement of students’ mathematical communication skills through the application of problem solving integrated Think Pair share (TPS) in mathematics. This research is an experimental research with two design pretest-posttest group. The instrument consisted of test instruments. The data analysis of the results of the study used the t-test. The results of the study obtained a t count of 9,143 when it is compared to the table with a value of 1,708. The significant value is 0,000 <0.05 so that Ho is rejected or the Think Pair Share (TPS) integration problem solving learning model can improve students’ mathematical communication skills.
