<![CDATA[This research aims to determine the effectiveness of the cooperative learning model type team assisted individualization (TAI) with realistic mathematic approach at Grade VII SMP Negeri in Sengkang. The population of this research were all students of Grade VII in one of SMP Negeri in Sengkang and one class selected randomly as the research sample. Data collection was performed by using the observation sheets of learning accomplishment, learning achievement test, observation sheet of students’ activity and questionnaire of students’ responses.
