An LMS is the most basic infrastructure used in e learning. Various types of LMSs are used, covering open source and commercial software. Moodle is one of the most widely used LMSs today. Moodle has many features that are educationally useful because of its long history and contributions of community. Moodle’s wide variety of functions is sometimes criticized as being too complicated to use. It is necessary to develop an LMS with various functions inside a simple and user-friendly GUI. In this paper, a Moodle GUI has been improved by mapping the main functions of a Moodle course to OKMindmap, which is an open service that runs on the Web, so that learners and teachers can use LMS services in a simple and convenient way. The developed results are demonstrated by applying actual class scenarios with which course activities, supplementary resources, and additional guide information were successfully integrated into a mind map.
