Ubiquitous Presenter:Supporting Active Learning in the
Classroomand more!
Beth SimonUniversity of California, San DiegoComputer Science and Engineering
Ubiquitous Presenter (UP)
• What is it?– How is it related to UW CP?– How is it different?
• Usage reports– Who is using it and how?– What do students think?
• How do I use it?
UP: An extension of UW CP
• Intended to be a strict superset– Usually within six months of UW CP release
• Replaces networking technology with web-based networking
• Supports student interaction from any web-enabled device– Tablets, Laptops, Cell phones, PDAs, etc.
• Web-based storage of lecture materials– Instructor notes– Student activities
How does UP work?

Projector
Differences with UW CP
• Network uses standard web-based technology through a central server
• Automatic web-archiving and review of
• Support for student interaction from non-Tablet devices
Differences with UW CP: Networking
• TCP/IP through a central server– Time delay for student device update (3
second polling)– Instructor must have internet access to store
lectures• Though we are network interruption tolerant
– No un-tethered lecturing
I have to buy and install a server?
• We provide hosted classrooms on our server– http://up.ucsd.edu– Server in San Diego is supporting:
• British Columbia• Missouri• Georgia…
– But you are more “at the whim” of network status
• Planned summer code release if you want to run your own locally
Differences with UW CP
• Web storage of instructor inked notes– Provides student portal-like access to
instructor notes for stroke-by-stroke review (at instructor’s discretion)
• Web storage of student-produced work– Allows review of peer materials– Instructor can control which specific
submissions are viewable
Supporting all devices
• Students interact with any web-enabled device through a browser
• Ink solutions– Require Java to be installed
• Text solutions– Only require a browser– Enter text in a box, then click to place it on the screen
• Can be moved, updated later• More text boxes can be made
• Multiple Choice solutions– Choice of how many times students can vote– Results summarized and can be repeatedly “polled”
• Students select their mode of interaction
Who is using it and how?
• Fall 2005– More than 10 active classrooms at more than 6
institutions• UCSD, California State San Marcos, San Diego State,
Northwest Missouri State, UBC, Ft. Lewis College• Computer Science(N), Mathematics(1), Physics(3),
Economics(1), Biology(1)
• Recent Classrooms around the country– Medicine(2)– We are looking to target a broad range of disciplines
and explore K-12
Does it improve student learning?
Do the students like it?Heck, do they use it?

Do you think the instructor's use of the tablet presentation system in this course had an effect on your attention to lecture?
Lecture Presentation SystemCS1 (N=59)
• 81%:– Paid more attention to lecture
• 97%– Felt understanding lecture was easier
• 95%– Would encourage other faculty who use PPT
• 90%– Felt reviewing ink on line made understanding lecture
easier
Student Participation System
• 77%– Increased their confidence in their abilities
• 91% – Seeing other students’ solutions had positive effect on
learning experience
• 77% – Would have rarely or never volunteered an answer in
class
• 67%– Reviewed other student solutions after class
Summary
• Tablet PCs can enhance learning in the classroom• Classroom Presenter and Ubiquitous Presenter support
active learning in novel ways with novel affordances– Anonymity– Electronic capture– Quick display and review with class
• INVITATIONS TO USE THE SYSTEM– Classroom Presenter– Ubiquitous Presenter
