The other day I came across software that allows a handheld to remotely control a computer on a network. While the software takes a little getting used to, I am intrigued at how this application might be used in the classroom to promote student dialogue, discussions about learning, and reflective writing strategies for active learning.
Pebbles was created as a part of the Pittsburgh Pebbles PDA Project's at Carnegie Mellon University. While the current focus of the project include the use of handhelds for people with disabilities, including the new EdgeWrite input technique, and the use of handhelds as "personal universal controllers" for appliances, I always like to explore ways emerging technologies might be used in the classroom with students to foster what works in learning.
Basically, three applications that make up Pebbles, the Remote Commander, Scribble, and Shortcutter on the handheld provide all of the navigation capabilities of the computer mouse and keyboard. All you need to enter on the handheld is the IP Address of the remote computer. As I write this piece I am using
Remote Commander to input my text. I can pause in my writing and use the stylus on the handheld to click on Internet Explorer in my QuickLaunch bar and navigate to my favorites to go to the Pebbles Project web page.
To browse Pebbles Internet information I switch to
Shortcutter on my handheld and with previously created "panels" I can click on links, go back or forward, scroll and page up and down. All typical browsing functions that I perform with the computer mouse and keyboard are controlled with the handheld. Switching to
Scribble, with the stylus I can annotate anything on the computer screen. (This works like the Pen tool in Microsoft PowerPoint slide shows) The cool thing is, though, that any handheld connected to the network through Pebbles can "scribble" on the computer screen at the same time!! Each handheld is identified with a different color line and cursor style!
One other application I especially like in an earlier version of Pebbles is
PebblesChat where handhelds connected via the network to the computer could "instant message" with just the other handhelds. The developers did not bring this app into the newest version of
Pebbles 6.0 but the 5.0 version is still available for
download.
Now, what about those classroom uses?? With an LCD projector connected to the computer the possibilities are endless! Students can work together to co-write; teachers can get exit slips for student understanding of content instantaneously; students can explicitly mark a text source to reveal understanding; teachers can receive instantaneous feedback from students through quizzes that they created in Microsoft Word.
With more than one computer in the classroom, groups of handhelds could be connected to different computers so that students could co-author PowerPoint slides or work together in a graphic organizer from Inspiration. Each student handheld can control what happens on the screen!
While the interface feels a little clunky to start with (as with all freeware before it becomes a commercial product) with just a little investigation and training the possibilities are endless with this software in the creative teacher's classroom to get kids to talk and be more than passive learners!!
Let me hear what you are doing with
Pebbles in your classroom!
