This research aims at describing the effect of cooperative learning model of Teams Games Tournament (TGT) and motivation toward physics learning outcome. This research was a quasi-experimental research with a factorial design conducted at SMAN 2 Makassar. Independent variables were learning models. They were cooperative learning model of TGT and conventional learning model. Motivation as moderator variable was divided into two factors, namely high and low learning motivation. The dependent variable was physics learning outcome. The instrument was a questionnaire of motivation to learn physics used to measure the motivation of students. Whereas physics achievement test was used to measure the physics learning outcome of the students. There were 36 students of class X in SMAN 2 Makassar taken using random sampling techniques as the research samples. The data were analyzed using two ways of ANOVA. There were some findings of this research. First, the physics learning outcome of the students taught using cooperative learning model TGT was higher than students taught using conventional learning models. Second, the physics learning outcome of students who had high motivation to learn physic and were taught using cooperative learning with TGT was higher than students taught using conventional learning model. Third, the physics learning outcome of students who had low motivation to learn physic and were taught using cooperative learning with TGT was not significantly lower than students taught by conventional learning model. However, the learning outcome between those two learning models were significantly different with α = 0, 05. Fourth, there was a significant interaction effect between learning model and motivation toward physics learning outcome of the students.
