See my Flickr: Note this! blog entry for details about how we used Flickr with our students.
This room has 25 computers running Windows XP. All are networked with very good broadband connection. Good range of applications including: Microsoft Office, AppleWorks, Visual Studio (programming), Stagecast, Revolution Dreamcard, MSW Logo and various educational programs. There is also a computer projection system, a video player (attached to the projector) and an OHP.
Could be better
The "spur" that divides the rear of the class makes it impossible for the teacher to see all the screens at the same time.
No place for students to work in small groups off the computers. (The small writing desks attached to the orange seats are inadequate.)
Good big room with lots of space. Can take bigger classes without feeling crowded and has space for teacher to move easily to work with the students on the computers.
Good projection facilities. Although the wires under the desk look messy, there is no tripping hazzard as they are concealed in the floor where they emerge from under the desk.
