Abstract
This study aims to determine the effect of cooperative learning model type of group investigation on student’s conceptual knowledge and activities in the subject work and energy. This research is a quasi-experiment using two-group pretest-posttest design. The study sample consisted of two classes, namely the XI MIA-1 class as the experimental class and the XI MIA-3 class as the control of which amounted to 32 students, the sampling be done with random sampling technique. The instrument used was a test of learning outcomes in the form of students conceptual knowledge in the form of 8 essay test. In the experimental class the average activity of students in the three meetings, are 60%, 72% and 87%. From the data obtained, there is evidence of the effect of group investigation models in improving learning activity on work and energy topic in XI Senior High School 10 Medan. The hypothesis with t-test shows the result there was a significant influence of cooperative learning model type group investigation to conceptual knowledge student subject of work and energy in class XI SMA Negeri 10 Medan T.P 2018/2019. Keywords: cooperative learning type group investigation, activities, conceptual knowledge

Summary
Knowledge of principles and generalizations education is a conscious and planned effort to includes knowledge of certain abstractions create an atmosphere of learning and learning which summarize observations of phenomena. This abstraction has the greatest benefit in potential to have religious-spiritual power, describing, predicting, or determining the self-control, personality, intelligence, noble most appropriate and relevant action or character, and the necessary skills himself, direction to be taken. Models and structures who are still very alarming This achievement includes knowledge of principles and is certainly the result of learning conditions generalizations and the interrelations between that are still conventional and do not touch the the two that present a clear, complete and realm of the dimensions of the students systematic view of a complex phenomenon, themselves, namely how the actual learning
