The current Site Setup Tool of Sakai CLE provides a way to create course sites for faculty based on the course/section information from Student Information System (SIS). However, it requires several steps to complete and it does not provide a way to let faculty know how many students are willing to use their course site. Also we think that course sites should be created by faculty's willingness to use, and course sites nobody uses should not be created. To assist this strategy, we have developed a new course site setup tool named "Course Link" tool to provide a lightweight linkage tool between Student Information System and Sakai CLE. The Course Link tool is implemented by using Entity Broker and assists faculty to create their course site easily. In our presentation, we will describe our experiences of this tool in 2014 first semester.
