%L UNY24993 %A Mustadi Ali %X Learning community in primary schools becomes the basis of developing the quality of education since in the early ages of the students. Learning community is the community of learning among students, among teachers, both students and teachers which learn collaboratively in the process of learning. It leads to the strengthening of the character values of the students because it creates community of learning. Basically in learning community, there is no rivalry in learning and no competition among the students but they are collaboratively learning and caring to each other instead. There are 3 basic principals of learning community: 1) the right to learn, where every student has special uniqueness and potential and the teachers should give opportunities for each student to learn; 2) teachers do not teach but they make the students learn; 3) education is for public, the class should be opened for public to observe. Those three basic principles become the basis in conducting school reform. School reform here means how schools build learning community where students and teachers learn to each other to create quality education, equality, and social harmony through open class based on collaborative learning. Japan has progressively implemented LSLC for several decades, especially in some areas like in Fujikawa, Yoshiwara, Shimone Ushiku, and currently in Agarie, Yagachi, Sate Kunigami, Nago. While in Indonesia, it is currently occupied in schools such as in Pasuruan, Halmahera, and Bantul.
