In this develompent research aims to produce products in the form of student worksheet in the learning cycle model,and the test to know the effectiveness of using this product student worksheet in cycle learning. This development research uses the Akker research stage. The subject of this research is the students of class VII of SMP Negeri 1 Pringsewu in academic year of 2016/2017. This Research data obtained through the test of mathematical communication ability. The result of the research and development that obtained is the form of student worksheet in the learning cycle model which has been developed is valid according to the material expert, media expert and linguist, practically used according to the students and effective enough to improve the mathematical communication ability
