I've often seen sites making this boast, but this really does seem to be the case with Lesson Writer. The website takes you through the various stages of preparing text based lesson plans for EFL / ESL students.
You just copy and paste in a text, the site analyses the vocabulary and produces a glossary of the voacaulary which you can customise, example sentences using the vocabulary, as well as grammar and pronunciation tasks and activities. You then just add your own comprehension questions and print the whole thing up along with a suggested plan!
There a Lesson Writer Demo here that shows how it's done.
I'm not so sure about copying and pasting in copyright materials, but as long as you have permission then this is a great way to produce relevant lesson materials from authentic sources and it won't take you all day to prepare them.
If you register on the site you can save the lesson plans and materials, and it doesn't seem to cost anything! I keep wondering where the catch is, but I can't see one.
Happy EFL / ESL lesson planning!
