Every implementation can have a Moodle course. If you create Moodle course from Sisu you will have course information and students imported from the Sisu into the Moodle course.
The other option is to send request to have Moodle course area. You need to use course enrolment key in these courses. For the students perspective it is much simpler to participate on Sisu-Moodle-implementation than to use course enrolment key.
From previous course implementations in Moodle you can easily transfer materials to the new course template using the Import function. You can import individual sections or copy the previous implementation in its entirety as long as you have teacher privileges on both courses. If you want material from a colleague’s course you should ask him or her to add you to his or her own course as a teacher.
