Accessibility barriers in higher education put visually impaired learners at a disadvantage compared to their sighted peers. When it comes to higher education, STEM disciplines are significantly more challenging for learners with vision or cognitive issues due to the vast number of images and graphs that include important concepts and concepts.
What is Alt Text?
Why Provide Alternate Text for Graphical Images?
Graphical images, charts, and graphs are essential for understanding complex concepts, particularly in STEM subjects. Visually impaired learners face barriers if these visuals lack descriptive alternate text (alt text). Providing alt text ensures all students can access, understand, and engage with educational content.
- Enhances Accessibility: Alt text enables screen readers to convey the content of graphs and charts to visually impaired learners.
- Ensures Inclusive Learning: Every student, regardless of vision ability, can engage with course materials.
- Communicates Key Data: Trends, comparisons, and important insights in visuals are clearly described.
- Supports Academic Performance: Prevents learning gaps by making essential information accessible to all learners.
- Legal Compliance: Helps meet accessibility regulations such as WCAG 2.1, ADA (Americans with Disabilities Act), and Section 504 of the Rehabilitation Act.
Common Challenges in Creating Alt Text Manually
Creating alt text for graphs and charts manually can be complex and resource-intensive. Key challenges include:
- Time-Consuming Process: Writing accurate descriptions for hundreds of graphs in textbooks or course materials takes significant time.
- Requires Subject Matter Expertise: Descriptions must convey the correct data, trends, and insights, which needs deep understanding of the subject.
- Inconsistency in Descriptions: Different authors may describe the same type of graph differently, leading to confusion for learners.
- High Costs: Hiring experts to manually create alt text for large volumes of content can be expensive.
- Scalability Issues: Manually adding alt text to vast collections of digital content is impractical for institutions with extensive course materials.
