Visual Models

Animated and stationary images are powerful communication tools. They allow us to create mental models and understand relationships. It is often said that a picture is worth a thousand words. With that in mind, we use graphics to provide clarity and make concepts memorable.

CD4 and CD8+ Cell Counts

This animated graphic enables learners to visualize an abstract relationship that is important in understanding blood test results.



HIV Replication Process 

New HIV case managers are often unfamiliar with how HIV replicates and spreads in the body. Images of the disease process allow learners to create a mental model that facilitates understanding. Animating the process allows learners to start with foundation information and sequentially build on what they know. We used narrated animation to help learners understand this complicated process.



Viral Load Changes in HIV

This graph is from a portion of a lesson about viral load changes in a person with HIV. The information is difficult to understand, so we explain it with narration and use visual cues to focus attention and clarify the message. Use the NEXT button in the lesson to view sequential screens.


This printable job aid was included in the training as a handy, post-training visual reference to remind librarians when to send in each required form as they enter the two-year funding period for a government reimbursement program.
