Engineering Design for Educational Interfaces

This document explores the essential criteria for designing effective educational interfaces, focusing on simplicity, consistency, coherence, usability, accessibility, and usefulness. It emphasizes the importance of considering user engagement and motivation in the design process, highlighting trade-offs between different criteria. The evaluation of the Swiki design team illustrates how educational interfaces can meet diverse needs while addressing potential user challenges. Recommendations for improving usability through standardization and enhanced navigation are also provided to ensure a rich educational experience for all users.

  1. Engineering Design for Educational Interfaces Nathan Balasubramanian Nick Joseph Jodi Kiefer Isaac Sanders

  2. Introduction • Educational Considerations • 6 Basic Criteria • Criteria Tradeoffs • Relationships Between Criteria • System Evaluation – The Swiki Design Team

  3. Educational Considerations • Motivation • Engagement • Intentionality • Feedback-driven Assessment

  4. Six Basic Criteria • Simplicity • Consistency • Coherence • Usability • Accessibility • Usefulness

  5. Simplicity & Consistency • Simplicity • limited type & color styles • short text lines • simple structure • Consistency • navigation • text formatting

  6. 3. Coherence • Eliminate extraneous material (i.e. pictures/sounds/words) • Remove unnecessary text (i.e. in-depth explanations) • Similar to Reseeding Phase in SER Model

  7. Usability & Accessibility • Usability • Good labeling • Spatial Contiguity (text close to relevant picture) • Reduce working memory load • Accessibility • Interface accessible to everyone • Minimal technology requirements

  8. 6. Usefulness • Limit the focus • Know the audience • Address student needs • Use emotional impact

  9. Criteria Tradeoffs • Simplicity • Less powerful features / Interfaces less useful • Consistency • User may feel “Controlled” or “Confined” • Usefulness vs. Usable • More complex = less usable • Accessibility • Advanced technology is less accessible but more useful • Coherence • User engagement issues

  10. Relationships Between Criteria Moderation is key to success • Hand-in-hand (“AND”) Relationships • Usability Consistency • Simplicity & Coherence • “Versus” Relationships • Usefulness vs. Usable • Usefulness vs. Accessibility

  11. System Evaluation: The Swiki • Educational Considerations: • Motivation • Engagement • Applying the 6 Basic Criteria: • Simplicity • Consistency • Coherence • Usability • Accessibility • Usefulness

  12. The Swiki: Pros • Supports Wiki Markup Language & HTML • Wider range of users • << Usability >> • Consistent Navigation • Navigational Side-Panel • << Consistency >> • Uploading Capability • Easy-to-use • << Usability >>

  13. The Swiki:Recommendations for Improvements • Standardizing User Contributions & Space • Color • Time Stamp & Name • Basic Generated Profile Pages • Subsection Navigation • Back Button within new page creation • Fixing “References to this Page” Link
