Abstract
The purpose of this study is to investigate the cognitive test instrument on Newtons laws of matter using the Rasch. This research was conducted in class X MIA MAN 2 Regency of Gorontalo, Gorontalo province. The number of samples in this study is 50 people. Instruments cognitive tests validated by three experts and declared eligible to use. While the results of the analysis using the Rasch on the map wright parts distribution ability learners showed that there was one that showed abilitas learners as high as 04P. Logit value of learners are +2.94 while for learners with low abilitas namely 36L and 43P, with a value of less than -1.09 logit.
