adding conditional blocks

Good Morning,

I am trying to create the following sequence:

    What is your level of supercomputing experience?
        if none then
            unit should be an html text component with information on which modules to study
        else
           can you identify your use case?
              if yes then
                 unit should be an html text box directing you (via link) to the use case module matching your use case
              else
                 unit should be an html text box directing you to an intermediate path

I have tried to accomplish this using the conditional - so first a poll,
     Have you ever used a supercomputer?
         Yes, No, A long time ago

Option 1: I tried building the conditional using the UI in the advanced problem in a Euclyptus instance - nothing all I get is a block that says "you must attempt supercomputing experience to see this material. I have attempted and even answered the poll question, but no go.

So I tried option 2: the old way - create a poll unit, create a unit with a component answer for the No result, a component answer for the yes and long time ago results. Export the course and edit the code in the vertical associated with the unit. However, I am still missing something because if I answer the poll question with 'no' I should get the simple html component but I get what you see below.

In addition, on the studio side I see:

and when I go into each of those blocks there is nothing in the individual conditional. I think I am picking up the correct sources for the Supercomputing experience poll, but the answers aren't being properly translated to display the components. The code that I modified in the vertical is below. Any and all suggestions are welcome.

Also - the How To Use Conditional Documentation is pretty sparse, I did use the Stanford course https://lagunita.stanford.edu/courses/StanfordOnline/OpenEdX/Demo/courseware/Conditionals/Conditional_content/ to get a better sense of how to do this, but we need clearer documentation if we are going to expand the community of course builders. The Stanford units are great but perhaps a bit out of date. I'm happy to be the documentarian once I get this resolved.

Thanks,
    Julie

Did you got the solution to this issue? I'm stacked in the same case... there is no way to get the poll answer value.

Hello Julia and Miguel,

for anyone working on this, just one suggestion:

instead of using polls + conditionals, why don't you use multiple choice questions + feedback to ask the questions and then inside the feedback you could add the proper link to the contents the user should be directed to in each case.

You could even hide the correctness in the MC question and also hide the destination units, in order to have the same behavior as the poll + conditional, but with less trouble.

I know it's been a while since Julia postes the question, but I hope it helps anyway.

:)

all best,

Juan Camilo

Hi Juan Camilo,

In the end I did roughly what you are suggesting. I was just wondering whether or not there was a cleaner way because you have to make sure that there are no "wrong" answers when you ask the question - and since each answer is "correct" but it is a single multiple choice question, it doesn't fit into the edX model as cleanly as I would like.

For now, I have use a work-around as you suggest.

Thanks for following up - I appreciate your comments because I can always learn a new technique and update the course, so these suggestions are always valuable.

Julie
