Callouts

Overview

Callouts are used to draw attention to important learning content that learners should notice, consider, or remember. They help emphasize key ideas, reflection prompts, important insights, or takeaways without interrupting the flow of the page.

Use callouts when information deserves additional emphasis because it supports understanding, application, or engagement with the course content.

Common Pitfalls to Avoid

  • Using callouts for content that could be presented effectively as standard text
  • Using too many callouts on a single page, reducing their impact
  • Including lengthy passages of content within callouts
  • Using callouts for required instructions or critical information that learners should not miss

Use Green Callouts to Highlight Reflections

These callouts are used when prompting learners to think critically about a topic, connect it to their own experiences, or evaluate their understanding. Reflection is important because it deepens learning, strengthens retention, and helps learners apply concepts more effectively in new contexts.

Use Purple Spotlight Callouts to Highlight Important Insights

These callouts are designed to draw attention to meaningful examples, expert perspectives, or industry insights. They help reinforce learning through concise, relevant content that connects concepts to real-world practice.

Do Not

ID

Use Over 400 Characters

Using more than 400 characters in a callout box reduces its effectiveness by undermining its role as a focused content design element. Callouts are intended to surface key ideas quickly, allowing learners to scan and engage without disrupting the flow of the main content. When they become too long, they compete with primary material, increase cognitive load, and are more likely to be skipped. Keeping callouts concise supports clarity, scannability, and ensures they function as intentional highlights rather than secondary content blocks.

Embed Media in Callouts

Embedding media should not be used within callout boxes because it weakens their purpose of directing attention to key learning cues and supporting understanding. Callouts are meant to be brief and easy to process, highlighting insights, reflections, or real-world connections. Adding media increases cognitive load and can distract from the main takeaway. Media works better in the main content, where it can be clearly introduced and explored. Keeping callouts concise and text-focused ensures they remain effective instructional signals.

Include Images

Including images in callout boxes reduces their effectiveness by shifting them away from their role as focused content design elements. Callouts are meant to highlight key ideas quickly and clearly, supporting scanability and reinforcing learning cues. Images add visual weight and complexity, which can distract from the intended message and interrupt content flow. Visual media is more effective in the main content, where it can be properly introduced and aligned with learning objectives. Keeping callouts text-focused preserves their clarity and purpose.
