text data entry
I want my students to be compelled to enter text data before they can click a button to reveal the correct response. I have working this into my courses for several years but each time I have to spend huge amounts of time fighting with the variables. I just don't understand the underlying logic. I've read through all the discussion chains I can find and it's still hit or miss when I'm working up a new project. This should be such an easy exercise in logical equivalence but there's something I'm missing. Is there a fundamental tutorial on this?
