advice
Add processing cues to the explanation
Add cues that mark what to select and how the explanation is organized when the visual is dense or includes nonessential material. For example, stress key words in speech, add arrows on the relevant graphic elements, and show headings or a simple part map for the lesson sections.
reason
Why signaling works here
Signals direct attention to relevant words, picture parts, and lesson sections. This reduces incidental processing on nonessential details and helps viewers select and organize the intended information.
Mechanism: Signaling guides viewers toward the important verbal and visual elements and clarifies the structure of the explanation, so less capacity is spent deciding where to look or how the lesson is organized.
Evidence: Learners showed better problem-solving transfer from a signaled multimedia explanation than from the same explanation without signals (Mayer & Moreno, 2003).
context
Use when the explanation is embellished or visually confusing
- User Goal: Understand an explanatory animation despite extra facts or confusing graphics.
- Task: Pick out the essential words, visual targets, and section structure.
- Data: A multimedia explanation with relevant content mixed with potentially distracting detail.
- Chart Setting: The design cannot fully remove the extra material, but it can add cues such as emphasis, arrows, headings, or a section map.
- Audience: Viewers who need help selecting and organizing the essential material.
- Success Criterion: Viewers focus on the intended parts and understand the explanation better.
exceptions
Do not use when the explanation is already concise and coherent
Break it when: The explanation is already concise and coherent without extraneous facts or confusing graphics. Why: The paper presents signaling as a load-reduction method for cases where extra material remains and needs guidance.
costs
Tradeoffs of adding signals
Sacrifice: The explanation gains extra visible or audible cues.
Risk: If the cues highlight nonessential details, they will not reduce incidental processing.
Mitigation: Cue only key words, relevant picture parts, and the major sections of the explanation.
mistakes
Common failure mode
Mistake: Adding arrows, emphasis, or headings that do not map to the essential explanation. Why it fails: The cues do not help viewers select or organize the material that matters.
check
Check whether the signals guide the intended reading path
Failure Sign: The display leaves viewers without clear cues about what is important, where to look, or which section they are in.
Quick Check: Ask whether the explanation explicitly marks key words, the relevant picture elements, and the current section.
Stronger Test: Compare the same explanation with and without the cues.
fix
Fix missing guidance cues
- Stress key words in the spoken explanation.
- Add arrows or similar marks to the relevant visual elements.
- Add headings, an outline, or a simple map that shows which section of the explanation is being presented.
