OEC Multimedia Integration 4 — Questions and Answers
Question 1: What is the recommended minimum color contrast ratio between text and its background for normal-sized text to meet WCAG 2.1 AA standards in online course materials?
- 2:1
- 3:1
- 4.5:1 (Correct answer)
- 7:1
Correct answer: 4.5:1
WCAG 2.1 Level AA requires a minimum contrast ratio of 4.5:1 for normal text to ensure readability for users with low vision.
Question 2: An educator wants to use a Creative Commons image in a course video. Which CC license allows use WITHOUT requiring attribution?
- CC BY
- CC BY-SA
- CC0 (Public Domain Dedication) (Correct answer)
- CC BY-NC
Correct answer: CC0 (Public Domain Dedication)
CC0 releases the work into the public domain, waiving all copyright, so no attribution is legally required.
Question 3: A student reports that an embedded podcast episode auto-plays loudly when they open a course page. Which WCAG guideline does this violate?
- Guideline 1.1 – Text Alternatives
- Guideline 1.4 – Distinguishable (Correct answer)
- Guideline 2.2 – Enough Time
- Guideline 3.3 – Input Assistance
Correct answer: Guideline 1.4 – Distinguishable
WCAG Guideline 1.4.2 (Audio Control) requires that auto-playing audio lasting more than 3 seconds can be paused or stopped, or have volume controlled independently.
Question 4: What is the key difference between synchronous and asynchronous multimedia in online instruction?
- Synchronous media uses video; asynchronous uses audio only
- Synchronous requires real-time participation; asynchronous can be accessed on-demand (Correct answer)
- Synchronous content is always recorded; asynchronous is always live
- Synchronous content requires Flash; asynchronous uses HTML5
Correct answer: Synchronous requires real-time participation; asynchronous can be accessed on-demand
Synchronous multimedia (e.g., live webinars) requires simultaneous participation, while asynchronous multimedia (e.g., recorded lectures) can be accessed at any time.
Question 5: Which screen-recording and video-editing tool is widely used by K-12 and higher education instructors specifically for creating flipped classroom content?
- Camtasia (Correct answer)
- Final Cut Pro
- DaVinci Resolve
- Adobe After Effects
Correct answer: Camtasia
Camtasia by TechSmith is a popular educator-focused tool that combines screen recording with easy video editing, quizzing overlays, and LMS export features.
Question 6: When an educator converts a PowerPoint presentation to a video for an LMS, which setting preserves slide transitions and narration timing correctly?
- Export as PDF
- Record Slide Show, then Export > Create a Video (Correct answer)
- Print to XPS format
- Save as PNG image sequence
Correct answer: Record Slide Show, then Export > Create a Video
PowerPoint's 'Record Slide Show' feature captures narration and timings, and 'Export > Create a Video' renders those into a playable video file with all animations intact.
Question 7: A teacher embeds a simulation that uses Java applets. Why will this likely fail for most students in 2024?
- Java applets require a paid browser plugin subscription
- Major browsers removed support for Java applets over a decade ago (Correct answer)
- Java simulations only run on Windows operating systems
- Simulations cannot be embedded in iframe elements
Correct answer: Major browsers removed support for Java applets over a decade ago
Browser support for Java applets was deprecated and fully removed by major browsers by 2017–2019, making Java-based simulations non-functional for modern learners.
