                                  Submission
Use an example to make a
pedagogical point
   Have all students think about the
    example
   Use student responses in the discussion
Topological Numbering
   Given a set of tasks with precedence
    constraints, find a linear order of the tasks
   Number tasks from 1 to n, such that if there is
    an edge from a to b, a has a smaller number
    than b

Find a topological numbering for
the following graph

Discovery activity
   Activity was to make a specific point – if a
    graph has a cycle, then there is no
    topological order
   Deception was present
       Problem was stated asking students to find
        something that wasn’t there
   Ah-ha moment
       “I have never understood this before – but it is
        obvious”
   Important to have all students work on this
    example
Exploratory example, follow
up question
   Linked activities –
       Exploratory activity to get students to think about
        the range of pen based user interfaces
       Evaluation question
   Engage students in the problem area
   Generate different options
   Allow a question to answered with a specific
    context
Describe three different pen-
based interfaces for tic-tac-toe
What criteria would you use to
evaluate these user interface choices

Challenge problem
   Example to have student think about
    issues of handwriting recognition
       Main point is to show how it is hard
       Students work simultaneously
       Competition in getting the answers right
Handwriting Recognition:
Identify the following words

Recognition results
Invitation
   I am interested in finding additional
    deployments of Classroom Presenter
       Especially in disciplines other the Computer
        Science, and at range of institution types
   Contact me if interested

What concerns would you have about
using Tablet PCs in the Classroom?

Issues
   Wireless in the Classroom
       Still challenges associated with this
       Our solution has been to use ad hoc
        networking which works well (for us)
   Different style of teaching
       Requires an interactive instructor
       Shift in teaching paradigm
       More work (?)
