  • Conclusion
problems recommendations
Problems & Recommendations
  • Navigation System
    • Hard to locate ESMC
        • Role settings vs. Local navigation bar
        • URL is not easy for memorizing
        • Bread crumb links do not help much
    • Search results are sorted by categories 
        • add “Sort by relevance” function will help
    • Confusion of universal navigation bar 
        • Move “About” and “Help/FAQ” of UTOPIA up
problems recommendations cont d
Problems & Recommendations (cont’d)
  • Interface Design
    • Entrance page
        • “That’s the huge problem, it’s misleading!”
        • “Tell me what is this, don’t make me click on everything to find out what it is” Tool tips will help!
    • Consistency
    • Fonts
        • “It’s really small, and no body wants to read that!”
    • Color
        • Orange links?
        • Blue headers?
problems recommendations cont d18
Problems & Recommendations (cont’d)
  • Labeling/language
    • Not Teacher friendly language
      • Not TEKS language
          • ex. Platonic Solids Geometric Solid
          • “I’ve never seen platonic solid until I saw here.”
      • Too complicated
          • Not straightforward
          • Too much redundant information
    • Vague labeling terms
      • The Math Math(ematical) Concepts/ Math Formula
      • Number Paths, Guess the number-magic trick, The Human Counting Machine, A Math Mural
conclusion
Conclusion
  • Modify the search function to serve users’ searching behavior
  • Improve the navigation to locate ESMC from UTOPIA
  • Decrease the confusion of universal navigation bar
  • Match the Interface design with target user’s expectation
conclusion cont d
Conclusion (cont’d)
  • Improve consistency between entrance page and inside pages
  • Change vague terms
  • Add tool tips when users move the mouse over the graphics
