See this course’s project requirements

Deliver the repaired workshop notice and the review evidence assembled across all six lessons.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Provide clear event facts, action instructions and meaningful link labels.
  • Show a semantic heading outline and logical reading order.
  • Record image alternatives and a justified contrast decision.
  • Provide timed captions and a descriptive transcript for the sample clip.
  • Attach a keyboard trace, issue statuses and a scoped handoff.

Review and revise

Use these criteria to check your work and choose what to improve.

  • Clarity: essential facts and actions are understandable without visual guessing.
  • Structure: hierarchy and reading order match content relationships.
  • Equivalence: visuals and media have meaningful text support.
  • Evidence: tests and remaining limits are documented honestly.

Before you begin

The idea in everyday life

The workshop notice may include a short orientation clip. Captions help people follow audio at the appropriate moment, while a transcript makes the information readable independently. Automatic output can contain meaningful errors. Using the supplied fictional storyboard, you will create both forms and identify an important visual instruction that speech alone does not communicate.

The idea

Captions show speech and meaningful sounds at the time they occur. A descriptive transcript is a separate written version that also includes essential visual information.

Try it

One step at a time.

Use the sample or information you have permission to use. Keep your work as you go. You can pause between steps.

  1. 1

    Use this twelve-second fictional clip: 0–4 seconds, narrator says "Choose a session"; 4–8 seconds, narrator says "Review the time"; 8–12 seconds, a confirmation chime sounds while the screen says "Practice saved; no booking sent."

  2. 2

    Draft captions with start and end times aligned to these three segments. Include the chime if it communicates confirmation, and identify a speaker when needed for understanding.

  3. 3

    Create a separate transcript containing the spoken instructions plus the essential on-screen statement. Do not assume captions alone communicate silent visual information such as a confirmation message.

  4. 4

    Review wording against the storyboard. Correct "Review the time" if an automatic draft says "Renew the time." This is a meaning check, not merely spelling cleanup.

  5. 5

    Attach the caption draft and transcript to your notice packet. If no video tool is available, the timed script is the complete exercise; mark it as a prepared asset, not tested playback.

Example

See how it works.

Fictional prepared captions: 00:00–00:04 "Choose a session." 00:04–00:08 "Review the time." 00:08–00:12 "[confirmation chime]." The descriptive transcript adds: "The screen confirms: Practice saved; no booking sent." That final sentence matters because otherwise a viewer might think a real reservation was made. If the clip is produced later, integrate that information into narration or an appropriate description as well. Captions must be checked in playback for timing and readability; this paper activity prepares the content but cannot establish whether a particular media player exposes usable controls.

Check your work

Did you cover these?

  • All spoken phrases are captured accurately.
  • The meaningful chime appears in captions.
  • The transcript includes the no-booking visual confirmation.

What to finish

A timed caption script, descriptive transcript and correction note.

Common mistake

Watch for this

Treating unreviewed automatic captions as a verified final asset.

How can I tell I understand it?

Distinguish spoken audio, meaningful sound and essential silent visuals.
