Canvas LMS (Learning Management System) is an educational tool that connects student with teachers. Tools include assignment/grading dashboards, multi-media instructional recorders, notifications, and more.

Canvas is an open LMS (Learning Management System) created by Instructure that allows for the management of users and roles (faculty, students, etc), courses and sections, course content, assignments, and grades in a standardised format set by IMS Global.

Extending Canvas

While the current offering includes many features, the open framework allows heavy customisation in a safe way.

  1. The Canvas API allows you to access, update or delete a wide variety of content and settings. The format mainly complies with LTI 1.X specifications at present.
  2. Developing LTI Tools (External Apps) allows you to augment the standard offering and expand on available features. You can also release you're enhancements through many online forums including the EduAppCenter. IMS Global has provided some example code found here to jump start your project.
