AbstractThis paper provides an introduction to a members�?? Relationship Calculation Tool (ReCa) of Sakai platform and a brief discussion of its design research process. Learning Management Systems (LMSs) usually gather a range of users�?? performance log, which can be used in educational data mining in different perspectives, including social relationship exploration. However, data mining approach usually consumes a lot of manual work and requires database search skills. There is still no effective tool for instructors to find out participants�?? social relationship in online learning community. The main objective of ReCa design is to fill the gap by easily carrying out participants�?? social relationship matrix in Sakai platform.
