  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
