Abstract
This is experimental research. This research aims to examine the effect of cooperative learning based on ASSURE model on mathematic learning outcomes in class XI of MAN 2 Mataram. The population is entire students in class XI MAN 2 Mataram with XI Science-5 as experiment class and XI Science-4 as control class which is decided by cluster random sampling. The experiment class was divided into learning teams based on their learning style. The hypothesis test uses a separated variance t-test. Based on the hypothesis test we got that (1) There is a difference in the average of student’s learning outcomes that cooperative learning based on ASSURE model gets a higher score than direct method learning, and (2) cooperative learning model based on ASSURE takes significant effect on learning outcome that class with this model get higher gain-score category than direct method learning.
