WIPTE is the Workshop on the Impact of Pen-Based Technology on Education. Their annual conference will be held on October 16-18 this year and if you are in the area of Purdue University, you can get more information here.
Here is some more information from the WIPTE website:
WIPTE is open to anyone with an interest in instructional technology. A wide variety of disciplines are embracing Tablet PC's and similar pen-based devices as tools for the radical enhancement of teaching and learning. This conference is intended to leverage this shared passion and to identify best practices in the educational use of pen-based computing so that all educators may benefit from this next generation of technology. Each WIPTE paper presentation includes an assessment component as an important part of the presentation. The WIPTE program also includes keynote talks, poster presentations, vendor booths, panels, and special sessions.
Searching through the website, I found a couple cool videos. They look like they are definitely "sponsored" productions but interesting nonetheless.
This video shows how teachers and students at Forest Ridge of the Sacred Heart are using the digital organizer, OneNote 2007, tablets, and digital textbooks to change and enhance learning.
