Tim VanSlyke, an ESL teacher, developed a great Hot Potatoes Tutorial on his blog. Hot Potatoes, for those who do not know, is a free software application teachers can use to develop online exercises and tests.
I’ve placed the link to this tutorial on my Teacher’s Page under the section called Create Tests and Exercises. I also have quite a few other free online test-making applications under Student Tests on my Examples of Student Work page.
I believe (though, honestly, I don’t quite remember) that I have these two separate sections because the links on the Student Work page a just a little easier to use, and don’t necessarily require downloading free software.
