Classroom Presenter Tablet PC Based Classroom Interaction
System Students contribute to class using digital ink
on instructors slide Instructor views student submissions, and
selectively shows them to the class Activities embedded into slide based lecture Contrasts to ‘Classroom Networks’ pedagogy
Individual vs. Aggregated responses

What we are trying to achieve Reproduce interactive classroom
experience in a remote classroom Moderate level of spoken interaction in UW
course Promoting interaction in remote classroom
Design of UW lecture materials to encourage interaction
Supporting materials – directions on when to stop for questions
Classroom Technology

What we’ve learned so far
The course is in progress – feedback is positive, but we won’t really know what is going on until one of us visits
Students will take UW Midterm and Final, so there is going to be information on student performance
![Page 23: ConferenceXP for Tutored Video Instruction Richard Anderson, Fred Videon University of Washington ConferenceXP Workshop November 2, 2006.](https://reader030.fdocuments.net/reader030/viewer/2022032704/56649d485503460f94a2397f/html5/thumbnails/23.jpg)
Technology Generally working well Some minor glitches with new version of
Classroom Presenter Audience audio is a problem for replay
Student noise is distracting A “facilitation interface” for
Presenter/Webviewer would be great! Lecture review by UW instructor is time
consuming
