How can you use alt text to make your e-learning courses more accessible?

由人工智能和领英社区提供技术支持

If you create e-learning courses, you probably use images, graphics, charts, and diagrams to enhance your content and engage your learners. But did you know that not everyone can see or interpret your visual elements the same way? Some of your learners may have visual impairments, cognitive disabilities, or low bandwidth that prevent them from accessing your images. That's why you need to use alt text, or alternative text, to make your e-learning courses more accessible and inclusive. Alt text is a short description of an image that is read by screen readers or displayed when an image cannot be loaded. In this article, you will learn how to use alt text effectively and follow some best practices for e-learning accessibility.

1 What is alt text?

Alt text is a text attribute that you can add to your HTML code or your e-learning authoring tool to provide a description of an image. Alt text serves two main purposes: it helps screen readers and other assistive technologies to convey the meaning and function of an image to learners who cannot see it, and it provides a fallback option for learners who have slow internet connections or blocked images. Alt text should be concise, clear, and relevant to the context and content of your e-learning course.

Make your e-learning courses inclusive by using alt text. Think of it like audio descriptions for images, so everyone, including those with visual impairments, can join in. Keep it short, sweet, and to the point, describing each image or interactive part. Consistency matters, so make it a habit. And, don't forget to test it out with accessibility tools and get feedback to make sure everyone's on the same page.

Alt Text is a text description added to an image in a digital document or webpage. It serves as a textual alternative for individuals who may not be able to see the image. Including alt text in your e-learning courses is crucial for making the content more accessible. Ensure that your alt text provides a concise and accurate description of the content and purpose of the image. You want to use clear language to convey the essential information. You want to describe the function and not just the appearance of the image. For example, if an image is a button or link, describe its purpose rather than detailing its visual characteristics. Another tip try to avoid redundancy.

2 Why is alt text important?

Alt text is important because it makes your e-learning courses more accessible and compliant with the Web Content Accessibility Guidelines (WCAG), which are the international standards for web accessibility. According to WCAG, all non-text content, such as images, should have a text alternative that serves the equivalent purpose. By using alt text, you can ensure that your e-learning courses are available and usable for all learners, regardless of their abilities, preferences, or devices. Alt text also benefits learners who are not visually impaired, as it can improve their comprehension, retention, and searchability of your content.

Apart from being a compliance issue, failure to include alt text can prevent some learners from participating in your courses or completing the exercises, particularly if relevant information is included in the images and not in the accompanying text. It is therefore important to include any information that is obvious to learners who are able to see the image, especially if the image includes learning content or knowledge that is relevant in order to complete assessment activities.

3 How to write alt text?

Writing effective alt text requires consideration of the type, purpose, and content of the image, the context and learning objectives of the course, and the needs and expectations of learners. To help you, here are some general guidelines: use plain and simple language; be descriptive and informative; avoid phrases like "image of" or "picture of"; include any important information or data; explain any actions or interactions; use alt="" for purely decorative images; and use aria-hidden="true" for complex graphics or interfaces that have their own text alternative or label.

4 How to test alt text?

To test if your alt text is appropriate and effective, you can utilize various methods and tools. For example, you can use a screen reader or a browser extension to listen to how your alt text is read aloud. Additionally, an accessibility checker or validator can scan your HTML code or e-learning course to detect any missing or incorrect alt text. You can also use a text-only browser or disable images to see how the e-learning course looks and functions without the images. Finally, you can request feedback from learners or experts who have different abilities, backgrounds, and perspectives and who can evaluate your alt text from their point of view.

5 How to improve alt text?

To make your alt text more engaging and effective, consider employing keywords and phrases that align with your learning objectives and content. Utilize active verbs and sensory details to create a vivid, memorable image in your learners' minds. Contrast and comparison can be used to emphasize differences or similarities between images or concepts. Analogies and metaphors can help explain complex or abstract ideas with familiar or concrete examples. Additionally, humor and emotion can captivate your learners' attention and interest, while questions and challenges can stimulate their curiosity and critical thinking.
