		abstract={This research is quasy experiment research with pre-test and post-test design. This research aims to investigate the influence of cooperative learning STAD model for student
learning outcomes on characteristic of living things topics. The research was conducted in class VII SMP Negeri 1 Medan academic years 2012/2013. The population of this research is 261 students of grade VII SMP Negeri 1 Medan and technique of interpretation for this research is cluster random sampling consist of 29 students as an experimental class (Archimedes) and 29 students of control class (Thomas A. Edison). 25 items of multiple choice test were used, and validated before they were applied. The result shows that pretest in experimental and control class are (72,41±8,96) and (76,83±8,64). t test reveals t calculated (-2,55) < t table (2,003); ά = 0,05. Prestest has no significant effect in the student’s preliminary knowledge. In the contrary, postest shows different result (experimental class 79,58 ±8,09; control class: 70,344±11,08). t test reveals that t calculated (2,35) > t table (2,00). This findings states that treatments has signnificant effects on the student’s
acheievement in Biology. It is advisible that STAD Model is incorporated in the learning process especially in teaching Biology.
