Manage Course Lessons
Add lessons, attach homework or exercises, open the editor, and keep the course structure readable.
Who this is for
Teachers building or reorganizing the lesson structure inside a course.
What this page answers
- Which lesson type should I create?
- How do child homework and exercise lessons fit under a class lesson?
- How do I reorder the course cleanly?
Prerequisites
- an existing course draft
1. Pick the lesson type intentionally
| Lesson type | Best for |
|---|---|
| Class lesson | the main teaching flow |
| Exercise | extra practice or reinforcement |
| Homework | work that students submit back to the teacher |
2. Use child lessons to keep related work together
Homework and exercises can sit under a parent class lesson so the course stays grouped by topic rather than becoming a flat list.
Child lessons auto-assign under every Learning Path strategy. If the course has a release strategy set (All at once, By date, After previous, Manual release), adding a child sub-lesson assigns it to every enrolled student the next time rules are applied — and the sub-lesson unlocks together with its parent. Only the Legacy strategy leaves sub-lesson assignment fully manual. See Learning Paths → Sub-Lessons for the full behavior.
3. Open each lesson in the editor to build content
Once the lesson exists, open it in the Lex Editor to:
- write the teaching content
- add widgets and media
- set lesson-specific controls
- add a cover image — upload your own or click Generate Cover to create one with AI (25 tokens). The AI uses the lesson title, description, content, and course context. Lesson covers appear as thumbnails on the course page.
4. Reorder the course when the outline changes
Use the course view to drag lessons into the right order and keep related content together.
5. Update Several Lessons at Once
Use Select on the course lesson list when you need to make the same change to multiple lessons.
Common batch actions:
- Edit shared settings such as status, lesson type, duration, answer reset, read-only mode, delayed answer reveal, time limit, assessment billing, or release rules.
- Copy selected lessons into another course.
- Archive active lessons you want to hide without deleting.
- Restore archived lessons from the archived view.
- Delete archived lessons permanently when you are certain they are no longer needed.
Select the lessons, choose the action from the batch bar, review the confirmation, and wait for the progress indicator to finish.
Permanent deletion is only for archived lessons and cannot be undone. Archive first when you only want to remove lessons from the active course outline.
