Subjects were students in first year of automotive department. Consisted of 25 male students who have the academic ability of the heterogeneous. The purpose of this research is to improve students' mathematics learning outcomes, especially in materials equation and inequality with with implementing cooperative learning approach to structural Think Pair Square. This research is a class action research. There are two cycles in this study. Each a cycle has four stages, the stages are planning, action, observation, and reflection. The results showed a rise in student learning outcomes. In the first cycle showed that the percentage of students who achieve the minimum mastery criteria is 56% and the second cycle was 72%, this indicates an increase in learning outcomes, before measures the percentage is only 28%. Conclusion the study shows that the application of cooperative learning approach to structural Think Pair Square, can improve student learning outcomes math first year of automotive department Dwi Sejahtera Pekanbaru vocational high school with the subject matter on the equation and inequality semester academic year 2012/2013en-USImprovingClass action researchCooperative learning Think Pair SquareMathematics learning outcomestudent Paper Post Degree
