7
This talk

• Demonstrate pedagogy based on student devices
• Examples from real classes
• Please participate!

Pedagogical goals

• Active learning
• Have students do something in class
• Achieve specific learning goals
• Classroom Assessment
• Determine level of understanding to adjust
  material
• Inclusion of student materials into discussion
• Diversity of ideas
• Examples to illustrate points
• Discussion of misconceptions

9
Examples

• Minimum cut example
• Example to engage students
• Topological search
• Discovery
• UI Choices and criteria
• Brainstorming
• Criteria identification
• Handwriting recognition
• Challenge problem
• Involve students

10
Introduce Problem with a concrete example

• Fully understand problem definition
• Discover aspects of the problem, gain intuition
• Appreciate the difficulty of the problem
• Become engage with the problem

Use an example to make a pedagogical point

• Have all students think about the example
• Use student responses in the discussion

14
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

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 wasnt there
• Ah-ha moment
• I have never understood this before but it is
  obvious
• Important to have all students work on this
  example

17
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

18
Describe three different pen-based interfaces for
tic-tac-toe
19
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

Invitation

• We are interested in finding additional
  deployments of Classroom Presenter
• Especially in disciplines other the Computer
  Science, and at range of institution types
• Contact us if interested

What concerns would you have about using Tablet
PCs in the Classroom?
Audience Submission
25
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 (?)
