Subject: [LON-CAPA-users] Math formulas are messy in MC choices
Message-ID: <YQBPR0101MB1587B72E309E38ED300C412E89DB0@YQBPR0101MB1587.CANPRD01.PROD.OUTLOOK.COM>

I have a question that has an image (of a graph) and multiple-choice options that contain Math equations to represent the graph. The equations are displaying really poorly in the Tex print out. Issues were:


- it would do a word wrap of each option so I entered {} around the equation to prevent it from breaking the equation into more than 1 line.


- It places the Math equation on a different line than the option A, B, C, .... So it looks strange.


- It looks like it is not taking advantage of the full space of the page (1 column mode)


I would like the Math equation to be on the same line as the option (A,B,C,...)  , not have an automatic word wrap and be able to have it look good in either horizontal mode or vertical mode.




Below you can see that I didn't place the curly brackets around the first option and how it automatically breaks the line, even though there is space on the line .


Any help is greatly appreciated.

Message-ID: <1520282045.2745426.1292436696.16497B9E@webmail.messagingengine.com>

Hi

I failed to find a solution to this seemingly simple and
universal issue.Conditional sequences might be the mechanism I am looking for, but I
could not find enough details and examples of implementation.
Assume I prepared and published a problem  'some.problem', and a
corresponding solution 'solution.pdf'.I imported the problem into a course and set the parameters duedate and
answerdate.
I am looking for a mechanism that will allow me
(1) to include a reference to the 'solution.pdf' inside
    'some.problem'; and(2) will display 'solution.pdf' to the students only when 'answerdate'
    is reached and the answer for 'some.problem' is displayed.And I would like to achieve this for every problem inside a folder
and/or a course.
I would appreciate any hints on how to achieve that.

Thanks in advance,
Itay

HI Itay,

There these very handy "Blocks" you can insert in your problem code and I think the "postanswerdate" block will do what you want, but I'm including all four that can be found from the Insert menu on the "colorful" editor.  I would describe these as predefined conditionals so the postanswerdate pair, for example, will only display what is within the opening and closing tags after the answer has become available.  If you put your link to a solution PDF inside a pair of postanswerdate tags, that should do what you're looking for. The others work analogously I believe.

            <postanswerdate></postanswerdate>
            <preduedate></preduedate>
            <solved></solved>
            <notsolved></notsolved>

Itay,

If you are coding these problems new or have control over the code,
the following might work:

Publish the pdf file solutions as resources.

Within the problem you can place a postanswerdate block with a relative
link to the pdf file.

I have a really simple example at:
/res/ohiou/physicslib/ZZZ_testing ground/lucas/examples/PDFSolutions/Sample1.problem

<numericalresponse answer="$c" id="11">
    <responseparam name="tol" type="tolerance" default="5%" description="Numerical Tolerance" />
    <textline />
</numericalresponse>

<postanswerdate>
    <p>Check out the following link: 
    <a href="sample1.pdf"> sample1.pdf</a> for a solution to the problem.</p>
</postanswerdate>
<allow src="/res/ohiou/physicslib/ZZZ_testing ground/lucas/examples/PDFSolutions/Sample1.pdf" />

Mark

PS - I just saw that Doug posted something as well.

Here is a sample problem that uses a block for after solved:

<problem><startouttext />Enter the correct answer 42 to see the hidden text
or image:<endouttext />
<numericalresponse answer="42">


    <textline readonly="no" spellcheck="none" />

</numericalresponse>
<solved>
    <img encrypturl="no" /><startouttext /><p>Hooray!</p><endouttext />
</solved>
</problem>

Note that the solution could be, for example, a text/HTML block or an image.

Doug, Lucas, and Justin,

Thank you very much for your reply.
This is exactly what I wanted, and will employ, for problems that I
code.
What can be done for problems that others have authored?

Thanks
Itay

Hi Gene,

You better sit down for it:  <m>$\hat k$</m>   For i-hat and j-hat, I
prefer to use <m>$\hat\imath$</m> and <m>$\hat\jmath$</m> which removes the
dots.

Hope that helps,

Hi Itay,

I may be wrong about this and there may be an easier way -- hopefully someone will point that out -- but back to your original question then, the way that occurs to me would be conditional sequences. I'll share an example here in case that will help you assess if this is the right approach for what you want to do and perhaps provide a bit of guidance on how this works.  If you end up with specific instrucitons on how to do this perhaps you can reply to me off-list for more detail.

We make extensive use of conditional sequences in our lab courses to prevent students from accessing the postlab if they have not correctly entered their data into the Lon-Capa lab. Below is a graphic representation of what that looks like for one of our prelab -- lab -- postlab sequences. This screenshot comes from the "advanced editor" interface for creating the sequence.  The three "Res" blocks correspond to the prelab problem, the lab problem, and the postlab problem. The conditional references the lab problem (mapalias "inlab9") to see if all of the answers there have been answered correctly and if not, blocks access to the postlab problem. It looks like this:

(((&EXT('user.resource.resource.210.11.awarddetail','inlab9') eq 'APPROX_ANS') || (&EXT('user.resource.resource.210.11.awarddetail','inlab9') eq 'EXACT_ANS')) && ((&EXT('user.resource.resource.220.21.awarddetail','inlab9') eq 'APPROX_ANS') || (&EXT('user.resource.resource.220.21.awarddetail','inlab9') eq 'EXACT_ANS')) && ((&EXT('user.resource.resource.220.22.awarddetail','inlab9') eq 'APPROX_ANS') || (&EXT('user.resource.resource.220.22.awarddetail','inlab9') eq 'EXACT_ANS')) && ((&EXT('user.resource.resource.220.23.awarddetail','inlab9') eq 'APPROX_ANS') || (&EXT('user.resource.resource.220.23.awarddetail','inlab9') eq 'EXACT_ANS')) && ((&EXT('user.resource.resource.220.24.awarddetail','inlab9') eq 'APPROX_ANS') || (&EXT('user.resource.resource.220.24.awarddetail','inlab9') eq 'EXACT_ANS'))) || (&EXT('user.resource.resource.210.solved','inlab9') eq 'excused')

(The last line of the conditional provides a way for the instructor to allow access to the postlab for a student with an excused absence from the lab.)

Your conditional may be quite a bit simpler being focused solely on whether or not the problem has its answer available.  I have not done that in a sequence before, but I have referenced it within a problem  and it looks like this: $external::datestatus eq 'SHOW_ANSWER'  I am NOT sure how (or if it's possible) to use that type of reference with a mapalias and hope someone else can help with that?

The one other thing I'll  point out about my sequence below is the path from the lab directly to Finish. That provides a path so as to not conditionally hide everything else in the course (as I once did when I first started working with sequences).

In your case, if I understand correctly, your sequence would contain two resources: the problem and the solution and the conditional would come between them and would verify that the answer was available for the problem before giving access to the solution.  I imagine that you could have a string of problem and solution pairs if you provided also a direct path from problem to problem so that all the problems were unconditionally available while each solution had a conditional path from its respective problem.

My very long .02.  If that seems like a viable approach for what you want to do, I'll be happy to answer additional questions off-list.

Doug

Doug, Lucas, and Justin,

Thank you very much for your reply.
This is exactly what I wanted, and will employ, for problems that I code.

What can be done for problems that others have authored?

Thanks

HI Itay,



There these very handy "Blocks" you can insert in your problem code and I think the "postanswerdate" block will do what you want, but I'm including all four that can be found from the Insert menu on the "colorful" editor.  I would describe these as predefined conditionals so the postanswerdate pair, for example, will only display what is within the opening and closing tags after the answer has become available.  If you put your link to a solution PDF inside a pair of postanswerdate tags, that should do what you're looking for. The others work analogously I believe.



            <postanswerdate></postanswerdate>

            <preduedate></preduedate>

            <solved></solved>

Hi



I failed to find a solution to this seemingly simple and universal issue.

Conditional sequences might be the mechanism I am looking for, but I could not find enough details and examples of implementation.



Assume I prepared and published a problem  'some.problem', and a corresponding solution 'solution.pdf'.

I imported the problem into a course and set the parameters duedate and answerdate.



I am looking for a mechanism that will allow me

(1) to include a reference to the 'solution.pdf' inside 'some.problem'; and

(2) will display 'solution.pdf' to the students only when 'answerdate' is reached and the answer for 'some.problem' is displayed.

And I would like to achieve this for every problem inside a folder and/or a course.



I would appreciate any hints on how to achieve that.



Thanks in advance,

Itay

If any list subscribers encounter similar intermittent disordering of  
resources in a folder, as reported for a single course in the purdue  
domain on January 29th (see:  
mail.lon-capa.org/pipermail/lon-capa-users/2018-January/005273.html )  
I wanted to report back on the resolution of this issue.

The cause of the problem was traced to the %randomorder package hash  
in lonuserstate.pm.

To prevent this (rare) bug, domains running LON-CAPA 2.11.1 or 2.11.2  
can patch their LON-CAPA instances with lonuserstate.pm rev.1.149.2.1,  
as follows:

All on one line:

wget -O /home/httpd/lib/perl/Apache/lonuserstate.pm  
'http://source.loncapa.org/cgi-bin/cvsweb.cgi/~checkout~/rat/lonuserstate.pm?rev=1.149.2.1;content-type=text/plain'

then, depending on Linux distro/version:

service httpd reload

or

/etc/init.d/apache2 reload

or

/etc/init.d/httpd reload


This code change will also be incorporated in the next LON-CAPA release.
For details of the code change, see:
