I used to visit the website onestopenglish.com to get free materials for my lessons, except recently it has become subscription only at a cost of 24GBP (about 34€). OK, so people like me were downloading the free worksheets without ever for one moment considering actually buying anything from Macmillan publications, but surely that's what the net is for isn't it? If I have to spend that kind of money on materials, I would rather go and buy a nice book from my local English bookshop. Publishing houses like Macmillan have probably lost a lot of money in missed sales by giving away half the content of their books -too bad for them - nobody refuses freebies like that.
If you are a teacher or a learner of English I strongly advise you NOT to pay for anything on the net. The net is all about sharing information - freely. Some of the worksheets on onestop were quite good, but some of them absolutely appalling. Why on Earth would I want to pay for a worksheet that asks students to write in the spaces the past simple of half a dozen irregular verbs. Is that teaching? Why not tell your students to invest in a half-decent dictionary or grammar book, so that you can concentrate on helping them to learn something. I did actually spend money on a site called handoutsonline.com and was hugely disappointed with the shabby worksheets produced by lovers of Microsoft clip art.
The best feature on onestop English was probably the Guardian Weekly reading lessons. Here again, the net is chock-full of articles that you can use in class. It doesn't take a genius to prepare a reading article like the ones found on onestopenglish.com. You simply choose a few words from your chosen text that you think your students might not be familiar with, write a definition for each one and instruct your learners to match them up. Then ask a few comprehension questions and finish off with a discussion about the rights and wrongs of this particular subjet.
The communication technology available nowadays means that virtually all artificial language teaching resources are obsolete. We now have the marvelous opportunity to use materials that come from the real world and might actually be of interest to our students, unlike the total crap found in bestsellers like "Headway".
