Other deployments Presentation tool Widespread UCSD Ubiquitous Presenter UCSC, UMass, Virginia Tech, MIT

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

Minimum value cut u st v 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 Student Submission s t Cut value

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 DE A F I J G BC H K

Find a topological numbering for the following graph E F D A C B K J G H I L

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 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 Richard Anderson

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 (?)
