                                         Projector
A. Ceiling attached
      •   Obviously for large classroom
      •   Less damange
      •   Not need to adjust the focus
      •   Not to be obstacles for students
      •   Easy to make location
      •   But need to equipments not to be rubbed
      •   Can’t use new model with data viewer


B. Portable
      •   Need Cabinet to preserve (check-out / check-in)
      •   Bring in and back it whenever using

Writing Board
           Black-board vs. White-board
   Demerits for White-board
        Harzard – Marker, eraser , etc
           •    “…. the whiteboard marker and the eraser-solvent(liquid) is hazardous,
                  they should be used in well-ventillated area …”
        Lack of visuality
           •   Can’t see the board well at the back seats in large classroom
           •   White board make our eyes be tired
           •   Not easy to erase it with delay


   Problems for automatic whiteboard
           •   Takes much time to open and close it (too slow)
   Recommend
     •   Use Black-board
     •   Use Thick chalk (Chalk triple size - Non Toxic)
     •   Multi pieces black-board – larger space
     •   Hand-operated better than automatic
     •   But chalk dust is not good for IT equipments (make distance)

CIO office, SNU – Classroom for IT Age
                White-board is hazardous

       •   No light to use IT equipments

    Consider
       •   Intercept the light           - General blind is not suitable
       •   Durability                    - General blind is easy to out of order
       •   Class is OK                   - Impossible to use projects if it is wrong
       •   Beauty
       •   Price

    Recommend (see the following pictures)
       •roll screen : easy to remove scribbles
      • wood louver
      (black plastic for suntan is not beautiful, and special glasses for
     suntan is too expensive)
