OEC Multimedia Integration 3 — Questions and Answers
Question 1: Which audio file format offers the best balance of small file size and broad browser compatibility for online course audio clips?
- WAV
- AIFF
- MP3 (Correct answer)
- FLAC
Correct answer: MP3
MP3 uses lossy compression to achieve small file sizes and is supported by virtually all modern browsers and devices.
Question 2: An educator notices that an embedded H5P interactive activity does not display on a student's school-managed iPad. What is the most likely cause?
- The file is too large for mobile screens
- H5P requires Adobe Flash which is no longer supported
- The school's content filter is blocking the H5P domain (Correct answer)
- H5P only works in the Chrome browser
Correct answer: The school's content filter is blocking the H5P domain
School-managed devices often have content filters that can block third-party CDN domains like h5p.org, preventing H5P content from loading.
Question 3: What is the primary purpose of using a 'talking head' video combined with a screen recording in online instruction?
- To reduce video file size
- To build instructor presence while demonstrating content simultaneously (Correct answer)
- To satisfy FERPA requirements
- To avoid the need for captions
Correct answer: To build instructor presence while demonstrating content simultaneously
Combining a talking-head view with screen content maintains social presence and emotional connection while delivering procedural or conceptual instruction.
Question 4: Under Section 508 of the Rehabilitation Act, which type of multimedia content in a federally funded online course MUST include audio descriptions?
- Animated GIFs
- Podcasts with a transcript
- Videos containing visual information not conveyed in the audio track (Correct answer)
- Decorative background images
Correct answer: Videos containing visual information not conveyed in the audio track
Section 508 requires audio descriptions for prerecorded synchronized video when meaningful visual content (e.g., on-screen text, actions) is not already described in the audio.
Question 5: A teacher wants students to collaboratively create a multimedia presentation. Which tool is best suited for real-time co-editing of slides with embedded video?
- Adobe Premiere Pro
- Google Slides (Correct answer)
- Audacity
- Screencast-O-Matic
Correct answer: Google Slides
Google Slides supports real-time multi-user editing and allows embedding of YouTube videos, making it ideal for collaborative multimedia presentations.
Question 6: What is 'cognitive load theory' and why does it matter when designing multimedia for online learners?
- It explains why students prefer longer videos
- It describes how working memory has limited capacity, so media design should minimize extraneous load (Correct answer)
- It argues that text is always superior to visuals for learning
- It states that students learn best through audio alone
Correct answer: It describes how working memory has limited capacity, so media design should minimize extraneous load
Cognitive load theory (Sweller) holds that working memory is limited, so multimedia design should reduce unnecessary complexity to free capacity for meaningful learning.
Question 7: Which of the following is an example of the 'redundancy effect' that can HURT learning in multimedia design?
- Using narration without any on-screen graphics
- Displaying full on-screen text while a narrator reads that exact text aloud (Correct answer)
- Pausing a video to let students take notes
- Adding background music to a podcast
Correct answer: Displaying full on-screen text while a narrator reads that exact text aloud
The redundancy effect occurs when identical information is presented in two channels simultaneously (e.g., narration + full text), overloading working memory rather than aiding comprehension.
