The experimentation of mathematics learning by using Cooperative Learning Model of Modification Jigsaw Type And Jigsaw is viewed from the Learning Creativity of Junior Students in Nganjuk Regency. The objectives of Research are (1) to find out the differences of Mathematics Learning Achievement for students who use cooperative learning model of modification Jigsaw type, Jigsaw Cooperative Learning and Conventional Learning. (2) to find out the differences of Mathematics Learning Achievement for the students have the different Learning Creativity Grade.(3) to find out the differences of Mathematics Learning Achievement for the students on application of cooperative learning model of modification Jigsaw Type, Jigsaw Cooperative Learning and Convensional Learning have a different learning creativity grade.The concluclusion of research are that: (1) The studentsâ mathemetics learning result that be taught with Modification Jigsaw Cooperative Learning Model is betterÂ than that be taught with Jigsaw Learning, the studentsâ mathematics learning result that be taught with modification jigsaw cooperative learning model is better than that be taught with conventional learning and the studentsâ mathematics learning result that be taught with jigsaw cooperative learning model is better than that be taught with conventional learning. (2) The studentsâ learning result who have a high learning creativity as good as with the students have a medium learning creativity, the studentsâ learning result who have a high learning creativity is better than the students have a low learning creativity and the studentsâ learning result who have a medium learning creativity as good as with the students have a low learning creativity. (3a) On every learning model, the students with a high learning creativity, the studentsâ mathematics learning result equal the students who have a medium learning creativity, the students with a high learning creativity, the studentsâ mathematics learning result is better than the students with a low learning creativity and the students with a medium learning creativity, the studentsâ learning result equal the students who have a low learning creativity. (3b) On every creativity grade, mathematics learning result with modification jigsaw cooperative learning model is better than jigsaw learning model, mathematics learning result with jigsaw cooperative learning model is better than conventional learning model and mathematics learning result with modification jigsaw cooperative learning model is better than conventional learning model.Keyword: Modification Jigsaw, Jigsaw, conventional, learning creativity, learning result.
