Sound recording is more straightforward if your film only needs voiceover (eg. voices for animated characters), sound fx and/or music. This is for a number of reasons:
Use your camcorder, especially if its digital - you are unlikely to get better results using a mini disc, ipod or tape deck. And its already in the format your editor will be working with.
You're recording has to fit with the picture - your sound of running water might be good close up, but it might fit better if you record it from further away. If in doubt, record several options to choose from

It will be very useful to an editor if you identify each item you record by announcing it on tape before you record; and make a careful note on your log sheets about each sound clip and its timecode - remember there will be no scenery to help work out what the sound is intended for.
When recording a whole class reciting something: try a smaller group, and a solo voice version too. Because sometimes the big group makes it sound muddy & difficult to understand
