I was expecting to get a correct checkmark in the summary if this code is in the graph:
correct: when (g4.number(`R`)=60 or g4.number(`R`)>60) true otherwise false
But no checkmark is added
Iam not sure whatâs happening
Thnak you
Itâs slide 2
Your math input, m4, needs a correct sink or readOnly: true. Also, for your correct sinks you donât need a when-otherwise. You just need to define all the conditions you want met. And, you can use âgreater or equal toâ like this:
correct: g4.number(`R`)>=60
Still not showing in the summary. I donât know why.
I think this is outside my knowledge. Maybe has something to do with the resetOnChange? I see an X in the preview when I have an answer in the input. Also, Iâm not certain, but I think if thereâs no interaction with the graph it wonât grade, so that should have readOnly: true. Could be wrong though.
Youâre getting the dot because students donât interact with the graph component, yet its marked with correctness.
The dashboard is. interpreting it as - everything that has been attempted so far is correct but there is stuff on the screen that hasnât been touched yet.
To avoid this make sure that you follow these rules:
- put correctness in the component that the student does the work in, even if the calculation is done behind the scenes elsewhere
- mark stuff that students donât interact with direactly as readOnly: true
Youâre also capturing values from the âstartâ button (btn1) and building a list used to calculate âbest attemptâ. Do you mean to move it over to act9?

It took me a while to understand it but I understand it now. It doesnât work for me and it actually does make much sense either.
Let me explain it.
Traditionally Math was repetitive and computation oriented. Nowadays we are focusing in understanding, which is fine, but sometimes we forget fluency, which in my opinion is also important.
The desmos I am building tries to solve this problem and make sure all my students (I have all kinds of students DL, ESL, low income⌠many different levels) are fluent in basic operations that later will need in class. It also allows me during remote learning having students from the same class solving so different things like: 2x+3x and (-3x+2)^2
The way you guys thought that âcorrectâ is that the student is doing one thing per slide. But I believe is much more powerful when we can achieve a higher level of interaction and we make the student work hard to solve that slide.
What happens to me is that, for every exercise, I reset the input of the student. Therefore, because Desmos do not detect interaction from the students does not add the check mark in the summary.
I donât understand why you are putting this requirement of âthe student must have interacted with the componentâ and you do not let the programmer decide. You are limiting possibilities here.
Instead source interacted would give the programmer the flexibility to check interaction, while people like me, could be free to decide when the student is correct.
It would have saved me so much time that correct check mark in the dashboard! It would have allowed me to monitor student progress really fast!
Thank you anyway for you answers!
The reason why I must move the âbest attemptâ to another button is because on the other button act9 I capture the timing. The grade is time based to assure fluency. Itâs computed using an exponential decay function. I can not capture the grade until the time is captured and the grade is computed. It took me a while to understand it myself.
readOnly: true is your way of deciding the student doesnât need to interact with the component. It doesnât mean you canât use aspects of that component in the correct sink of another component a student actually interacts with. Whatever correctness condition you wanted in the graph put into the correct sink for the input instead.
If put readOnly: true in both the graph and the Math input, a dash is showed in summary.
If I put readonly: true in the graph only then the problem I have is that because I erase the student input on the Math input, Desmos is waiting for the student to put in something to give the checkmark. But thatâs not what I want.
There is no way of achieving the checkmark the way I have programmed it.

I understand now. My bad.
Ok ⌠I have a screen that randomly selects a table for a student to complete.
If the randomly chosen table to completed correctly it marks ALL of the other tables correct.
The only other components on the screen are a note and a a media file [gif].
In my attempt to debug the issue I set up the note to give feed back on the correct status of each table.
When I do the table correctly all of the other tables are marked correct and the dashboard remains a dot ⌠not a checkmark. I am a bit of a loss. There is the Activity.
Thatâs a lot of tables on one screen!
Trouble is, youâd need to denote each table not being used as readonly: true to get that correct check.
Iâd recommend simply doing a different table for a different screen.
Thanks Mike!
I was hoping to have each student get a slightly different table and I couldnât figure out how to randomize the initial text for different cells. This was my plan B!
I am truly amazed how fast your response time is for these Desmos questions.
You all rock over at Desmos!
Again than you for the feedback!
Have a perfect evening!
