Searching for information on the net about a topic is not as easy as it may seem, especially if you're an elementary student of English. Don't just ask them to use the net to research a topic. There's so much information about any topic, that they will feel lost. As a result, they will copy and paste the first thing they set their eyes on. Besides, there's the language barrier. Not every piece of information is adequate to their langauge level, so they won't understand what they read and will soon lose interest.
So try to make their search easier and adapt the language to their language level giving them clear instructions. An example of this is a WEBQUEST. If you don´t know what that is, visit this site:
So, here is a WEBQUEST on "RAINFOREST ANIMALS" I created for my 7th grade students.
It's their first webquest. I hope they're enjoying it!
