[LON-CAPA-users] online lab grading: read student data

I wonder how much data and of what type and for what kind of
If you are talking about definitive (predetermined) data which will always
be the same for a given lab group, then you would probably want to hard code
it into the resources.
On the other hand if you are talking about data which will be variable for
individuals, perhaps experimental data that they measure, then that is quite
a different matter.
You can use
to retrieve student submissions for a particular response in a problem in a
published sequence. What you do with it in other problems in that sequence
is up to you, and your cleverness with perl.
I myself have only used this in fairly simple ways, so far.
Such as, starting the sequence with a survey question, in which the students
select which starting material they used in a organic chem synthesis
experiment. Some of the subsequent questions in the sequence then use that
information to tailor their individual questions to match their response.
In the above case I put a condition on the link from that first survey
question, to prevent them from accessing the rest of the sequence until they
have responded to the survey.
If this is the kind of thing you are interested in let me know and I will go
look to see if it is open source.
I'm sure others have done other even more interesting stuff.
