The Aimed Of This Research To Applied Numbered Head Together (NHT) Cooperative Learning Model To Improve Social Studies Learning Outcomes For Fourth Grade Students Of SDN 051 Tarakan. This Research Used Class Action Research. The Subjects Of The Research Were 16 Students Consisting Of 8 Male Students And 8 Female Students. This Research Was Conducted In 2 Cycles, Each Cycle Consisting Of 2 Meetings. The Procedure Of Each Cycle Consists Of Planning, Action, Observation, And Reflection. Data Obtained In This Research Include Students’ Activity Observation Sheet, Teacher Activity Sheet, Cognitive Aspect Assessment, Affective Aspect, And Psychomotor Aspect. The Finding Of The Research Is Numbered Head Together (NHT) Cooperative Learning Model To Improve Social Studies Learning Outcomes For Fourth Grade Students Of SDN 051 Tarakan. The Cycle Learning I Outcomes Student’ In cognitive Aspects 62,50% In The Second Cycle Increased To 87,50%. In The First Cycle, Earning The Achievement In Affective Aspect 43,75% In Cycle II Increased To 93,75%. Then In The Cycle I Student Learning Outcomes In Psychomotor Aspect 62,50% In The Second Cycle Increased Significantly To 93,75%. So It Can Be Said The Research Has Been Successful And In Accordance With The Success Indicators. Keywords: Numbered Head Together (NHT) Cooperative Learning Model, Learning Outcomes Social Sciences
