Selecting visual assets

Choosing the right visual assets for your online course isn't just about picking the prettiest pictures or the flashiest videos. There are several important factors to consider to ensure that the visuals you use enhance learning and engagement. Here are the key criteria to keep in mind:

• Relevance: The visuals should directly relate to the course content. An image or video must add value by reinforcing the learning objectives or clarifying complex concepts. For instance, a diagram of the human heart is vital in a biology course on human anatomy but would be out of place in a literature class.

• Clarity: Visuals must be clear and easily understandable. A cluttered or overly complicated graphic can confuse more than it clarifies. Ensure that each visual is simple enough to be understood at a glance yet detailed enough to convey the necessary information.

• Quality: High-resolution and professionally designed visuals not only look better but also convey professionalism and credibility. Poor-quality images or grainy videos can distract from the learning experience and may even undermine the perceived value of the course.

• Accessibility: Make sure that all visuals are accessible to all students, including those with visual impairments. Use alt text for images, provide captions and transcripts for videos, and ensure that colours and designs are visible to those with colour vision deficiencies.

• Copyright: Always use visuals that you have the right to use. This can mean creating your own, purchasing them, or using royalty-free images from reputable sources. It's important to respect copyright laws to avoid legal issues and to model ethical behaviour for students.

Include some information on sources

By keeping these criteria in mind, you can select visuals that are not just attractive but are effective educational tools. They should help students grasp the material better, remember it longer, and engage more deeply with the content.
