HI Jacob,
I haven't worked with GeoGebra so may be missing something, but for other
things I've done, I've sometimes added a part that the students don't see, set
the weight to 0 and used responses with hiddenline boxes as in the tutorial to
store information. This has the unfortunate consequence though of potentially
confusing students if they look at an interface that shows them that there were
4 parts when in fact they see only three.
Alternatively, more recently I've used a custom response to store additional
information in a part that the students DO see but use the customresponse
processing to check their answer only against the relevant part of the
submission. Here's an example:
<customresponse answerdisplay="$key" id="11">
<answer type="loncapa/perl" id="1_8">if (substr($submission,0,5)==$key) {return
'EXACT_ANS'; }
return 'INCORRECT';</answer>
<hiddenline />
</customresponse>
In this case, I control the submission from my JavaScript widget and know that
it will be exactly 5 characters long, so I'm comparing only the first give
characters of the student submission against the correct answer (and showing
the correct answer in the answer display) but I have additional information
stored after the first five characters of the submission which I'm using to
reset the display to match the student's submission. If you'll have a variable
number of characters in the correct answer, I would think you could add a
special character of some kind following their submission (: or | for example?)
and then use that to delineate where their answer stops and your data starts.

Subject: [LON-CAPA-users] Having javascript variables persist through submission
I am working on using GeoGebra for having students do graphing (for example
using this app:
<https://urldefense.proofpoint.com/v2/url?u=http-3A__ggbtu.be_m2820289&d=BQMFAw&c=8hUWFZcy2Z-Za5rBPlktOQ&r=lm_7ZS7-EAc__llGmOcR7rpM4OG1Bat_vcdWNBw5ZVA&m=FYWeWpOjYT9pl0KX39HAaD0CJ-vEHamKvkMvZiAiIoc&s=3EfqONotnrQ2Q3KLDaOwsb31KuakqKe5IPrnH6a8Vys&e=>http://ggbtu.be/m2781237<https://urldefense.proofpoint.com/v2/url?u=http-3A__ggbtu.be_m2781237&d=BQMFAw&c=8hUWFZcy2Z-Za5rBPlktOQ&r=lm_7ZS7-EAc__llGmOcR7rpM4OG1Bat_vcdWNBw5ZVA&m=FYWeWpOjYT9pl0KX39HAaD0CJ-vEHamKvkMvZiAiIoc&s=uERjrgZGR6FpQttIyTZ45rgXaOWHsQleLizWWRoXmmQ&e=>
)
I would like to have the graph persist after submission as in the tutorial
videos (

<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.lon-2Dcapa.org_geogebraTutorial.html&d=BQMFAw&c=8hUWFZcy2Z-Za5rBPlktOQ&r=lm_7ZS7-EAc__llGmOcR7rpM4OG1Bat_vcdWNBw5ZVA&m=FYWeWpOjYT9pl0KX39HAaD0CJ-vEHamKvkMvZiAiIoc&s=qExMMDR36H5tiaIZT7X4y0FWOjHkyBBCT3RFS6FANpk&e=>see
especially video 3B)
However, I am checking the slope and x-intercept and so I don't have a
submission box to store the coordinates of the points when the graph is
submitted. Is there another way to keep the values, like setting them as a
variable for Perl or something?
Thank you,
Jacob
