Whitespaces in output

[Tom Hill]

When checking student output, do you separate the output stream into
tokens, then compare expected result/student token pairs?

So if expected result is:
The answer is 12.

And student produces:
The answer is12.

The answer is marked incorrect, not a presentation error?

[Zhigang Sun]

Yes, I do use tokens to judge. But the separators I use are white space, \n, \r and \t. You can see the detail in diff() from assignment.class.php.

The student you mentioned can't get a PE but a WA since the token in his output is "is12" and "is" and "12" are expected.

For my $.05, I really like students being responsible for white space. White space is significant in every computer language they are likely to use. (Ancient Fortran ignored it)

The drawback is an assignment getting a 0 grade for a single typo in a
description label.
And it is tedious finding such errors.

Today is my first day installing it, so I have no experience trying to
tailor this automatic evaluation tool to my needs.

But I agree, I too will need the ability to assign an appropriate almost
right grade to an almost right answer.

I also will be slanting my use towards student resubmittal, since that is an
often encountered learning opportunity.

I have used it most of this semester and found it to be great tool.
It gives students immediate feedback and lightens my load.

But the only feedback they get is correct/incorrect, so they can have
trouble knowing what to correct.

I have been putting a sample run in the description and making my
first test case the sample run.

This is along the lines of what I plan. I usually have two public test
cases, and then I want a battery of special test cases, which students
cannot discover and thus tailor their code for.

Have you ever tried the feedback field of each test case? When the students get WA on that case, the corresponding feedback will be shown to them. So it can be used as an auto hint tool.

For example.

Sun-
I cannot find the feedback field to which your refer.

In the testcase setting page, the feedback fields are under every case's output field
