In today's digital-first educational landscape, creating accessible learning materials is imperative to ensure equitable education for all students. With 15% of the global population living with some form of disability (Word Health Org., 2021), accessible design directly impacts the millions of learners who rely on assistive technologies and alternative means to engage with educational content effectively.
When examining the sample learning object "Orchards and Vineyards," several accessibility strengths and weaknesses became apparent. The document demonstrated good structural organization with clear headings and logical content flow, making it easier for screen readers to navigate. The use of proper heading hierarchy (Heading 1 for the main title, Headig 2 for sections) provided a solid foundation for accessibility. However, significant barriers prevented many students from fully accessing the content. These issues highlighted common problems found across educational materials that can exclude learners with disabilities from meaningful participation in their education.
The original document contained three images with minimal or missing alt text. I replaced generic captions like "Orchard" with descriptive alternatives such as "Rows of grapevines with supporting posts extending across a green field under daylight, showing organized vineyard cultivation." This change ensures students using screen readers can understand the visual content's educational purpose.
Several text elements relied solely on color formatting to convey meaning. I increased contrast ratios to meet WCAG 2.1 AA standards (minimum 4.5:1 for normal text) and ensured no information was communicated through color alone, making content accessible to users with color vision deficiencies.
Original figure references were inconsistent and unclear. I implemented proper sequential numbering (Figure 1, Figure 2, Figure 3) with clear textual references in the body content, allowing all users to understand the relationship between images and text regardless of their ability to see visual layouts.
The document contained varied font sizes that could create reading difficulties. I established consistent typography with minimum 12-point fonts and clear visual hierarchy, ensuring readability for users with visual impairments or reading difficulties.
I fixed the heading hierarchy to follow proper sequential order without skipping levels, creating a logical document outline that screen readers can navigate efficiently. This structural improvement helps users understand content organization and jump between sections easily.
The reference link was converted from a raw URL to descriptive text that explains the link's destination and purpose, helping users understand where links lead before clicking and improving navigation for screen reader users.
The revision process began with conducting an accessibility audit using both automated tools and manual review techniques. I systematically examined each element against WCAG 2.1 guidelines, documenting barriers and their impact on different user groups. Changes were implemented progressively, with testing after each modification to ensure improvements didn't create new accessibility issues.
Recommended Accessibility Resources:
WAVE Web Accessibility Evaluation Tool. This free browser extension identifies accessibility errors and provides specific guidance for remediation, making it invaluable for content creators at any skill level.
Color Oracle. A free color blindness simulator that allows creators to see how their content appears to users with different types of color vision deficiencies, ensuring inclusive design from the start.
NVDA Screen Reader. This free, open-source screen reader enables content creators to experience their materials as blind or visually impaired users would, providing crucial insights into navigation and comprehension challenges.
Creating accessible educational materials requires intentional design and ongoing commitment, but the impact extends far beyond compliance. When we design for accessibility, we create better learning experiences for everyone—clearer navigation benefits all users, descriptive alt text helps in low-bandwidth situations, and logical structure improves comprehension across diverse learning styles.
