Aseptic Technique: Interactive WBT & Performance Support

Overview

 

This web-based training module introduces foundational aseptic technique concepts for clinical and healthcare environments. The course was originally developed to support certification preparation and procedural understanding for healthcare professionals.

​

The Problem

 

The original training contained dense on-screen text and limited interaction. While technically accurate, it did not fully support:

​

• Conceptual clarity between medical asepsis and surgical asepsis

• Behavioral reinforcement of contamination prevention practices

• Learner engagement through active participation

• Visual hierarchy to support cognitive processing

​

The challenge was to preserve regulatory accuracy while enhancing instructional effectiveness.

​

​

Design Approach

 

The redesign emphasized clarity, interaction, and structured learning flow.

​

Key Design Strategies

 

1. Reduced On-Screen Text
Condensed dense content into layered interactions and progressive
disclosure to improve readability.

 

2. Interactive Exploration
Used click-to-reveal and scenario-based interactions to reinforce distinctions between clean and sterile technique.

 

3. Visual Hierarchy Improvements
Refined layout structure, image selection, and spacing to guide attention intentionally.

 

4. Accessibility Enhancements (508 Considerations)

• Improved color contrast

• Added meaningful alternative text

• Structured tab order and keyboard navigation

• Streamlined audio to reduce redundancy

 

5. Performance Support Integration
Developed a companion job aid to reinforce contamination prevention behaviors in real-world application.

​

Instructional Design Decisions

​

• Differentiated medical asepsis vs. surgical asepsis clearly through visual and textual contrast

• Structured knowledge checks to reinforce key distinctions

• Used consistent layout patterns to reduce cognitive load

• Balanced compliance requirements with learner-centered design

​

Accessibility & Compliance Considerations

 

The updated module incorporated Section 508 alignment:

​

• Keyboard navigation compatibility

• Clear focus indicators

• Alt text for all instructional visuals

• Reduced redundant narration

​

Outcome

 

The redesign resulted in a 20% increase in successful certification completion.
