If I make the search:
http://www.google.com/dictionary/json?callback=dict_api.callbacks.id100&q=school&sl=en&tl=en&restrict=pr%2Cde&client=te
I end up with a response in JSON. I am not a programmer and I have no idea where to begin to take the results and then style them and turn them into something my students can read?
No offense, but if you're not a programmer, than perhaps returning the results in JSON is not a good plan? JSON requires something to interpret the results before display; generally javascript, but there are plenty of JSON parsers for other languages, and it's becoming a pretty common standard.
Regardless, you'll need to parse the results with something, and then display the results in something else. You'll need programming experience for this.
I agree with jvenema that JSON might not be the right format for you. However, you can try this JSON-visualizer and see if it fits your needs:

You will need to select "Eval" instead of strict "JSON" and trim the leading:
dict_api.callbacks.id100(
and the trailing:
,200,null)
before you click "Render" to get a good result.
