  1. An online educator wants to add captions to a video for students who are deaf or hard of hearing. Which file format is most commonly used for timed text captions?

    Answer: WebVTT

    WebVTT (Web Video Text Tracks) is the standard format for timed captions and subtitles used in HTML5 video elements.

  2. When embedding a YouTube video into an LMS, which attribute should be added to the iframe to improve accessibility for keyboard-only users?

    Answer: title

    The title attribute on an iframe provides a descriptive label that screen readers announce to users navigating by keyboard.

  3. A teacher records a 45-minute lecture. To improve online engagement, what is the generally recommended maximum length per video segment?

    Answer: 6–9 minutes

    Research on online learning (including Guo et al., 2014) consistently shows engagement drops sharply after about 6–9 minutes, so shorter segments retain attention better.

  4. Which principle of Universal Design for Learning (UDL) is primarily addressed by providing both video lectures and text-based transcripts?

    Answer: Multiple means of representation

    Offering information in more than one format (video + text) fulfills UDL's Multiple Means of Representation guideline.

  5. An educator is choosing between raster and vector graphics for an online diagram that students will zoom into on mobile devices. Which type should they choose and why?

    Answer: Vector, because it scales without quality loss

    Vector graphics (e.g., SVG) are mathematically defined and remain crisp at any zoom level, unlike raster images which pixelate when enlarged.

  6. What does the acronym SCORM stand for in the context of online education multimedia?

    Answer: Sharable Content Object Reference Model

    SCORM (Sharable Content Object Reference Model) is a set of technical standards enabling e-learning content to work across different LMS platforms.

  7. A student's screen reader cannot interpret an infographic embedded as a JPEG. What is the best accessibility fix?

    Answer: Write a detailed alt text or long description for the image

    Providing descriptive alt text or a linked long description conveys the infographic's informational content to users relying on screen readers.
