Multimedia Integration Flashcards

Which audio file format offers the best balance of small file size and broad browser compatibility for online course audio clips?

MP3 uses lossy compression to achieve small file sizes and is supported by virtually all modern browsers and devices.

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?

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.

What is the primary purpose of using a 'talking head' video combined with a screen recording in online instruction?

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.

Under Section 508 of the Rehabilitation Act, which type of multimedia content in a federally funded online course MUST include audio descriptions?

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?

Answer: Google Slides

Google Slides supports real-time multi-user editing and allows embedding of YouTube videos, making it ideal for collaborative multimedia presentations.

What is 'cognitive load theory' and why does it matter when designing multimedia for online learners?

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.

Which of the following is an example of the 'redundancy effect' that can HURT learning in multimedia design?

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.
