2. Introduction o Educational Considerations  6 Basic Criteria  Criteria Tradeoffs  Relationships Between Criteria System Evaluation – The Swiki System Evaluation – The Swiki

3. Educational Considerations Motivation Engagement Intentionality Feedback-driven Assessment

4. Six Basic Criteria Simplicity Consistency Coherence Usability Accessibility Usefulness

5. Simplicity & Consistency 1. Simplicity limited type & color styles short text lines simple structure 2. 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 4. Usability Good labeling Spatial Contiguity (text close to relevant picture) Reduce working memory load 5. 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 – > Consistent Navigation – Navigational Side-Panel – > Uploading Capability – Easy-to-use – >

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
