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

Examples Minimum cut example

Example to engage students Topological search

Discovery UI Choices and criteria

Brainstorming Criteria identification

Handwriting recognition Challenge problem Involve students

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

Partition the vertices into disjoint sets A and B, with s in A and t in B to minimize the edge values from A to B

Find a minimum value cut

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

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

Student Submission

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

Audience Submission

Recognition results

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 Richard Anderson anderson@cs.washington.edu

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

Audience Submission

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 (?)
