Verified Competencies Demonstrated by Ibrahim Özkan

By completing this curriculum to the standards of the IxDF Educational Codex, Ibrahim Özkan has demonstrated mastery of how to:

  • Identify accessibility failures specific to dynamic web pages, and apply WCAG 2.0 and ARIA to resolve them.

  • Use ARIA landmarks and live regions so screen readers can navigate and follow real-time content changes.

  • Make the legal, ethical, and business case for accessible interface design, including relevant disability legislation across the US, UK, and Europe.

  • Preserve expected navigation behavior in dynamic pages, including the back button, browser history, and bookmarkable URLs, so users aren't left disoriented.

  • Design for server failure and slow responses in Ajax applications, so users experience a graceful fallback rather than a broken interface.

  • Evaluate dynamic interfaces against the five goals of effective Ajax use: screen space optimization, maximizing efficiency, reducing page loads, real-time updates, and attracting user attention.

  • Apply progressive enhancement and graceful degradation to ensure dynamic pages work across all devices, browsers, and connection speeds.

  • Select appropriate JavaScript frameworks and libraries for a project, including the trade-offs between full frameworks like GWT and lightweight libraries like jQuery.

  • Design dynamic feedback that's timely, physically close to its cause, and meaningful to users, in line with established usability principles.

  • Manage the SEO implications of dynamically loaded content, and design Ajax pages that remain indexable by search engines.

  • Separate content, presentation, and behavior in Ajax implementations, as demonstrated through a complete real-world case study.

  • Explain how Ajax works technically, including XMLHTTPRequest, the DOM, and the difference between synchronous and asynchronous page requests.

  • Apply flow theory to dynamic interface design, understanding how feedback, interruption, and transparency affect user engagement and task completion.

  • Recognize and design around change blindness and attentional gambling to ensure users notice critical updates on screen.
