Why can't I see my students' answers?

Why can't I see my students' answers?

I use a lot of embeded questions when I write my quizzez. In a typical quiz students have to provide at least 20 short answers, often more (even 40) and such a long one embeded question constitutes one quiz.

When I review the reports for students' attempts, I can't see all of their answers. It happens very often that the last 5 or 6 boxes remain empty even though I know from the score that they have been answered. As a result, I can't give them proper feedback or correct their mistakes because I simply don't know what they've written.

PLEASE HELP! (Is it because there are too many boxes within one task?)

Tomasz,

I'll look into this if you can give me the data. It could be the code itself, or it could be memory constraints on your server if you have a lot of responses.

Hi Tom,

I think I know what the problem is (see my other post in this thread). Can you just let me know if I can safely change the field type from varchar to text?

Hi Tomasz,

I've had a closer look at Dorota's question in which this happened and I know why this is happening. The answer field in quiz_responses table is of varchar (255) type, which is simply not enough to hold the answers to a cloze question with so many blanks (Dorota had 23 blanks).

OK, one thing is knowing what the problem is, quite another is fixing it. I don't know much about how MySQL works, but I guess simply changing the field type from varchar to text (should be enough) or longtext (might be an overkill) would fix it.

PS
I think this one could be a good candidate for an issue. I'll file this as soon as we've arrived at final conclusions here.

Tomek, tell Dorota she owes me a beer (or a good coffee) wink
