LEARN has just been upgraded to Moodle 3.0 (latest version). This is a planned upgrade and it should not affect your course accessibility.
The upgrade includes some enhancements to Moodle course design, accessibility and assessment. Starting from next week, the e-Learning team is running workshops to highlight new features and enhancements.
If you have questions or concerns about this upgrade, please contact the e-Learning team via Assyst (https://assist.canterbury.ac.nz, log a request > e-learning services > e-Learning enquiry)
