2016-10-15 Thread Stuart Raeburn

Bob,

When you submit a web form, the form data sent by the browser will  
include the names of any input items where type="text", regardless of  
whether anything has been typed in the textbox.


Conversely, if the web form includes a radio button group, the form  
data sent by the browser will only include the (common) name of the  
radio buttons in the group, if one of the buttons has been selected.   
If it so happened that value="" for the selected radio button, then  
the form data would also include a a value of "" for that named element.


If none of the buttons in a radio button group has been selected, then  
the name of that group will not be included in the form data sent by  
the browser.


So, yes, the browser treats radio buttons differently from textboxes,  
such that in any submission you'll always see these three items:


HWVAL_12
HWVAL_16
HWVAL_18

in the "POST" item in the activity log created by a submission,  
because all are textboxes (input type="text"), but you'll only see  
this item:


HWVAL_14

if one of the radio buttons had been selected. And consequently you'll  
never see: HWVAL_14 =  (with the right side blank), because all of the  
radio buttons have an associated value in this case where the radio  
buttons are present because it is a numericalresponse item with  
question type set to exam.

Stuart,

Thanks for the detailed response!

I'm still confused about the line containing HWVAL_14 only showing up in a
POST  when there was a radio button selected but not at other times.  The
lines containing the other HWVAL_'s appear in every POST even when they
didn't have a value entered, and after they had values submitted.  So, from
your response, this resulted  because part 13 (HWVAL_14) was set to type
exam.  In fact, it was set to type exam.  If this is the reason, why are
exam questions  treated differently than the other questions?

/res/sfu/batchelo/chem111/problems/lecture/set7/M.mass.vol.relations.problem
is a four part problem containing four numericalresponse items (one for

The "POST" entries record the value(s) entered by the student in the web

numericalresponse in standard mode, or the value for a radio button which
is selected, (i.e., for numericalresponse in exam mode).

However, in a multi-part problem, each part has its own "Submit Answer"
button, and the only value(s) which will be stored (in the "CSTORE") is/are
for the response item(s) belonging to the part for which the "Submit
Answer" button was pushed.

The activity log shows the following actions:

20:16:47 Submit Answer button pushed for part 11
Value for response item in part 11 (id=12) was: .0045 M

20:21:01 Submit Answer button pushed for part 15

20:23:46 Submit Answer button pushed for part 17
Value for response item in part 17 (id=18) was .282 L

The button was never pushed for part 13, so no submission is recorded for
response item 14.

However, the radio button for response item 14 (in part 13) was checked
when the button was pushed for part 15 at 20:21:01, so the POST includes a
value for "0.593069306930693" for HWVAL_14, but the submission is not
recorded in the student's submission history, because the "Submit Answer"
button was not pushed for part 13.

Bob,

I am assuming the question type was set to "exam" for part 13, because  
/res/sfu/batchelo/chem111/problems/lecture/set7/M.mass.vol.relations.problem  
is a four part problem containing four numericalresponse items (one  
for each part).


The "POST" entries record the value(s) entered by the student in the  
web form when a submit button was pushed -- either typed into a  
textbox in numericalresponse in standard mode, or the value for a  
radio button which is selected, (i.e., for numericalresponse in exam  
mode).


However, in a multi-part problem, each part has its own "Submit  
Answer" button, and the only value(s) which will be stored (in the  
"CSTORE") is/are for the response item(s) belonging to the part for  
which the "Submit Answer" button was pushed.


The activity log shows the following actions:

20:16:47 Submit Answer button pushed for part 11
Value for response item in part 11 (id=12) was: .0045 M

20:21:01 Submit Answer button pushed for part 15
Value for response item in part 15  (id=16) was: 26.56 g

20:23:46 Submit Answer button pushed for part 17
Value for response item in part 17 (id=18) was .282 L

The button was never pushed for part 13, so no submission is recorded  
for response item 14.


However, the radio button for response item 14 (in part 13) was  
checked when the button was pushed for part 15 at 20:21:01, so the  
POST includes a value for "0.593069306930693" for HWVAL_14, but the  
submission is not recorded in the student's submission history,  
because the "Submit Answer" button was not pushed for part 13.

Re: [LON-CAPA-users] question about entries in the activity log

2016-10-14 Thread Mills, Douglas G
My guess would be in line with yours, that he clicked the radio button but did 
not hit the submit button for that part.  When he submitted the third question, 
Lon-Capa knew about the radio button but did not evaluate it.  It didn’t show 
up with the question 4 submission because when the page reloaded after question 
3 was submitted, question 2 went back to its default of no selections, since it 
had not been submitted, evaluated, etc. That’s what I expect took place, but am 
eager to learn if that is not correct.

Subject: [LON-CAPA-users] question about entries in the activity log

Hi,

I had a student who claims he submitted an answer and didn't get credit for it. 
 This happened during a quiz so he didn't get the problem status, or a receipt, 
at the time of the submission.  In looking through the activity file I see 
something that I don't understand and was wondering if it was somehow related.
The problem has 4 parts.  The 2nd part is a radiobuttonresponse and it is the 
one that the student claims to have answered.  In the activity log excerpt 
below, the 2nd part is HWVAL_14.

The thing that I don't understand is that HWVAL_14 doesn't show up in the POST 
on line 469 for the 1st part like the other parts do.  Then it shows up on line 
468 with a value.  Line 468 is a POST for the 3rd part as indicated by the 
submission in the CSTORE on line 467.  Then on line 465, the POST for the 4th 
part, HWVAL_14 is missing again.
Looking at the issue of not getting credit for the submission, did he click on 
a radio button but not the submit button for that part (the 2nd part).  Then 
when he submitted his answer for the 3rd part, the 2nd part POST'ed too but 
lon-capa didn't grade it since the submit was not for the 3rd part.  That seems 
reasonable.

Is there an explanation for the line HWVAL_14 appearing and disappearing?  I 
thought maybe the activity log might be corrupt but grading indicates "Nothing 
submitted - no attempts."

Are these 2 things related?

[LON-CAPA-users] question about entries in the activity log

2016-10-14 Thread Bob Gonzales
Hi,

I had a student who claims he submitted an answer and didn't get credit for
it.  This happened during a quiz so he didn't get the problem status, or a
receipt, at the time of the submission.  In looking through the activity
file I see something that I don't understand and was wondering if it was
somehow related.

The problem has 4 parts.  The 2nd part is a radiobuttonresponse and it is
the one that the student claims to have answered.  In the activity log
excerpt below, the 2nd part is HWVAL_14.

The thing that I don't understand is that HWVAL_14 doesn't show up in the
POST on line 469 for the 1st part like the other parts do.  Then it shows
up on line 468 with a value.  Line 468 is a POST for the 3rd part as
indicated by the submission in the CSTORE on line 467.  Then on line 465,
the POST for the 4th part, HWVAL_14 is missing again.

Looking at the issue of not getting credit for the submission, did he click
on a radio button but not the submit button for that part (the 2nd part).
Then when he submitted his answer for the 3rd part, the 2nd part POST'ed
too but lon-capa didn't grade it since the submit was not for the 3rd
part.  That seems reasonable.

Is there an explanation for the line HWVAL_14 appearing and disappearing?
I thought maybe the activity log might be corrupt but grading
indicates "Nothing
submitted - no attempts."

Are these 2 things related?
