I came across this educational site a few days ago and again, it has much to offer for ipad lovers. Its aim is to enhance learning with internet and instructional technologies and is packed with excellent posts and links (evven by bloggers) to a whole array of different applications and resources, enough to equip a teacher with a few lesson plans to get them going. I particularly like the main feature “15 favourite Apps by teachers” as it has been tried and tested by fellow teachers and also graded. Some applications you will probably know but there are others equally just as good. (please scroll down and read some comments as you will discover some more relevant teaching apps)
Overall I give this site a 8/10……
Please have a look and tell me what you think

Thanks for the link. I feel that the iPad inspires creativity and hands-on learning with features you will not find in any other educational tool — on a device that students really want to use. Powerful apps from the App Store like iBooks will also let students engage with content in interactive ways, find information in an instant and access an entire library. In addition, it helps promote collaboration and communication for enhanced learning.
