Multimedia Integration Flashcards

What does the 'signaling principle' in multimedia learning suggest educators should do?

Answer: Use cues like arrows, bold text, or highlights to guide learner attention to key information

The signaling principle (Mayer) states that learning improves when cues are added to highlight the organization and key elements of the material.

An educator is building a module on lab safety and wants the highest level of learner interaction. Which multimedia approach best achieves this?

Answer: A branching scenario simulation where choices lead to different outcomes

Branching scenarios require active decision-making, place learners in realistic contexts, and provide immediate feedback, maximizing engagement and retention.

What is the main advantage of hosting course videos on a streaming platform (e.g., Kaltura, Panopto) rather than uploading MP4 files directly to an LMS?

Answer: Adaptive bitrate streaming adjusts quality to the learner's bandwidth, reducing buffering

Adaptive bitrate streaming (ABR) dynamically adjusts video quality based on the viewer's connection speed, ensuring smooth playback even on slower connections.

A student using a screen reader encounters an audio player with no visible controls and no keyboard focus. Which WCAG principle is violated?

Answer: Operable

The Operable principle requires that all interface components be navigable and usable via keyboard; controls that cannot receive keyboard focus violate this principle.

Which video compression codec is most widely supported across modern browsers for HTML5 video without a plugin?

Answer: H.264 (AVC)

H.264 (AVC) has near-universal browser support and is the standard codec for web-delivered video due to its excellent compression efficiency and compatibility.

Which instructional design model specifically addresses the systematic design of multimedia-rich online courses with phases including Analysis, Design, Development, Implementation, and Evaluation?

Answer: ADDIE Model

The ADDIE model is the foundational instructional design framework, with its five phases guiding the creation and evaluation of multimedia learning experiences.

An educator wants to assess whether students actually watched an embedded video in the LMS. Which feature, if available, best supports this?

Answer: Using a video platform with watch-time analytics and completion tracking integrated with the LMS gradebook

Platforms like Kaltura or Panopto can report individual watch-time data and video completion percentages directly to the LMS gradebook, providing verifiable engagement evidence.
