RNA Seq Original.mp4

Challenge

Inconsistent audio delivery and clarity created barriers to comprehension, making it difficult for online learners to process key information.
The format did not fully support diverse learning needs, requiring a more reliable and learner‑centered resource.
Static PowerPoint slides paired with recorded narration limited accessibility, especially for learners who benefit from multimodal or text‑supported formats.
Lack of standardized pacing and audio quality reduced engagement, as learners could not easily revisit or control the flow of information.
A more accessible, consistent, and instructionally effective solution was needed to enhance understanding and support the overall learning experience.

Learning Theories and Models

✔️Updated Narration

RNA Seq Updated.mp4

Solution

Improved clarity and consistency by re‑creating the slide audio using Murf AI, ensuring a stable, high‑quality narration.
Enhanced comprehension and retention by removing distracting inconsistencies that previously interfered with processing the content.
Used the original transcript to generate an AI‑voiced narration, providing a more accessible and uniform delivery for all learners.
Strengthened learner engagement through clearer audio that supports focused attention and reduces cognitive strain.
Improved the overall learning experience by ensuring students could more easily understand, follow, and revisit key concepts.

PDF Tagging.mp4

Challenge

The research article existed only as an image‑based PDF, making it inaccessible to screen readers and violating accessibility best practices.
Learners using assistive technology were unable to access or navigate the text, creating an equity and compliance issue.
The file could not be properly tagged due to its format, preventing the creation of a structured reading experience.
Troubleshooting accessibility tagging revealed technical barriers and workflow challenges, delaying integration into the lesson.
A fully accessible, screen‑reader‑friendly version of the article was required to support Universal Design for Learning (UDL) principles.

Learning Theories

Solution

Converted the image‑based file into a true PDF format, enabling proper tagging and accessibility remediation.
Applied Adobe Acrobat tagging to structure headings, reading order, and alternative text for screen‑reader compatibility.
Resolved multiple technical glitches through tutorial research, iterative testing, and collaborative troubleshooting.
Worked with a mentor and team to walk through the tagging process, ensuring accuracy and compliance.
Delivered a fully accessible PDF that supports equitable access, improves usability, and aligns with UDL guidelines.
