<p>This research is a Class Action Research (CAR) with the purpose to analyze the<br />application of Inside Outside Circle (IOC) method in increasing the learning outcome of<br />natural science about the object’s characteristics and usefulness on the students of Class III A<br />the Elementary School of Kasreman on the first Semester of the 2018/2019 year academic. The<br />subjects of this research are the students of Class III A the Elementary School of Kasreman on<br />the first Semester of the 2018/2019 year academic as much as twenty four children; consist of<br />fifteen boys and nine girls. The data resources of this research are relating with learning<br />activities and learning outcomes. Techniques of collecting data of this research are non test<br />technique and test technique. The instruments of collecting data of this research are the sheets<br />of observation and the camera application on the hand phone and also daily test. Technique of<br />analyzing data of this research is comparative description. The procedure of this research is the<br />Kemmis and Mc Taggart’s spiral model that consist of two cycles; First Cycle and Second<br />Cycle. Each cycle is consisting of two meetings. The results of this research are 1) the<br />application of Inside Outside Circle (IOC) method in the learning of science about the object’s<br />characteristics and usefulness is a different task for each group, 2) the application of Inside<br />Outside Circle (IOC) method in the learning of science about the object’s characteristics and<br />usefulness is in a small group, consist of three-four members, 3) the applications of Inside<br />Outside Circle (IOC) method in the learning of science about the object’s characteristics and<br />usefulness are increasing the learning activities; actively in discussing, very actively in<br />answering the questions from the teacher and other students and very actively in asking to the<br />teacher, 4) the applications of Inside Outside Circle (IOC) method in the learning outcomes of<br />science about the object’s characteristics and usefulness are increasing the learning outcomes.<br />The learning outcomes on the Early Condition are 60,41 for the average and 47,82% for the<br />completeness. The learning outcomes on the First Cycle are 73,75 for the average and 73,91%<br />for the completeness. The learning outcomes on the Second Cycle are 84,58 for the average<br />and 91,3% for the completeness.</p>
