The researh is a CAR with Four stages namely planing, acting, observing, reflecting. Result carried out with the application of Wolfram Mathematica computational learning innovation are as follows: (1) The results of the questionnaire recap which have been distributed and filled in directly by students have a 24% percentage increase to 88% in the cycle to, (2) There is an increase in activity student learning with a description in cycle 1 hasa percentage of 63% who have a level of activity at the level of moderately active, and in cycle II of 75% who have a level of activity at an active level, (3) There are also inccrease the ability to solve students, the level of activity, and interest in learning for students is seen by the indicator of the average value in cycle 1 is 65 and the level of student learning completeness with 55% achievement. Then the average value of students in cycle 2 is obtained with a level 77 and the completenesslearning process reaches 98%, be concluded that the increase from every cycle is very significant and effective.Keywords: Improved, Mathematical Communication, Think Pair Share aPeningkatan Kemampuan Komunikasi Matematis Mahasiswa DIII Teknik Mesin Dengan Metode Think Pair Share
