The Closing Scene

Every lesson has an opening scene and at least one closing scene. The opening scene is where students start. The closing scene is where they finish — and reaching it is what finishes the lesson.

New lessons are created with both, so you never have to build an ending from scratch.

What happens when a student reaches it

The moment a student lands on a closing scene:

• The lesson is complete. The attempt is recorded as completed right then — nothing for the student to remember to do. (A Submit button set to Submits = Lesson also ends an attempt wherever it is pressed, and a lesson still needs one to publish. That gate is on its way out; reaching the ending is meant to become the only way a lesson finishes.)
• Their answers are locked. Whatever they answered is what counts. Nothing can be changed after arrival, so a student cannot wander back and edit a question after seeing their score.
• Their work is saved, and the student is told so.

While the save is in flight the student sees Saving your work…, then Your work is saved. alongside a Back to assignments button that returns them to their assignment list. If the save does not go through, they see We couldn't save your work. with a Try saving again button, which retries the save rather than replaying the lesson. If the connection dropped, the save also retries automatically when the device comes back online, while the student is still on the ending.

Playing again is a new attempt

Opening a completed lesson again from the assignment list starts a fresh attempt. The first attempt keeps everything it recorded; the new one records its own. You see both in the student's attempt history, so a retry never overwrites what happened the first time.

The ending Berdee builds for you

A new lesson's closing scene already has an ending on it:

• A headline — "You finished the lesson!"
• The student's score
• A celebration, held back until their work has saved, so the headline lands first and the confetti never fires over a failed save

Every piece is an ordinary widget. Select the headline and rewrite it, move the score, restyle either one, add an image or an audio clip, or delete the lot and build your own ending. It is your scene.

To make the ending respond to the score, with a cheer and the confetti only for a high score and a kind note for everyone else, give each piece a visibility rule or a condition on the lesson score. Step-by-step: Cheer a high score and encourage a low one on the ending.

The ending also picks up your lesson's theme automatically — change the palette and the ending restyles along with the rest of the lesson.

The score hides itself when there is nothing to score

If your lesson has no graded questions — a story, a read-along, a social-story walkthrough — the score simply does not appear. A lesson with nothing to grade should not end on a score of zero.

This is how the pre-made ending's score is set up. A Score widget you add yourself starts out showing zero instead — 0, 0%, or 0/0, depending on its format — on an ungraded lesson. Set its scope to Lesson so it reads the whole attempt, and set Nothing graded to Hide in its ⚙ Configure dialog to make it hide itself the same way. See Score Widget.

What a closing scene may not hold

Two rules, and they are the reason the closing scene can be trusted to mean "finished":

• No questions, no scored buttons and no answer-checking. The lesson is already graded and locked by the time the student arrives, so a question — or a press on a scored button — here could never count. Everything else is welcome — text, images, audio, video, a celebration.
• No way out. Nothing leads out of a closing scene. It has no outgoing paths, and the Lesson Graph will not let you draw one. Students leave with Back to assignments, not by navigating to another scene.

Berdee also checks all of this when you publish. Three things show up as warnings — they tell you what to fix, they do not stop you publishing:

• No student can reach an ending. Nothing in the lesson leads to a closing scene, so an attempt can never finish. Look for the Scene Has No Way Forward warnings alongside it — those name the scenes where the missing link belongs.
• Something leads out of an ending. A widget on the closing scene navigates somewhere, which would drop a student back into a lesson their attempt has already finished and locked.
• An ending tries to grade. A question, a scored button or an answer-checking button sits on the closing scene, where it could never count.

A lesson may have several endings

Most lessons need one ending. A branching lesson often needs more — one per outcome. Extra endings reach your lesson through an import today; an Add ending control in the scene panel is on the way, so what follows describes a lesson that already has several.

• Mastered
• Needs more practice
• Ask an adult for help

Each outcome is its own closing scene, so the paths to them are visible on the map instead of hidden behind conditions on a single scene.

• The first ending in your scene list is the default. The last scene of the lesson flows into it automatically, as long as that scene has something that advances it — a graded question, a Next button, a timer. A final scene of plain text with nothing to move it on is a dead end, and publish validation says so. See Scene Progression.
• Every other ending is reached by a path you draw. Wire it in the Lesson Graph like any other destination: a score path, a router, or a button that navigates.
• Each one shows as an End card on the graph, so you can see every way the lesson can finish at a glance.
• Berdee records which ending each attempt reached, so a branching lesson's outcome becomes part of the record — not just the score. It shows as Ending reached on the student's attempt page whenever the lesson has more than one ending (see Student Experience and Attempts).

_Example: A multiplication practice lesson ends two ways. A router after the last question sends students scoring 80% or better to Mastered and everyone else to Keep practicing, which offers a hint sheet to work through with a teacher._

Where endings live

• In the scene panel, endings sit in their own Ending section at the bottom, below your other scenes.
• In the Lesson Graph, each one draws as a scene card badged End, with no path leaving it.
