I am hoping someone can help me fix my code in order to have a student’s table value entries show up as correct (with a checkmark) on the teacher dashboard. I have managed to do this for all of my multiple choice questions, however I would also like to do it for the numerical values the students enter into a table.
Thank you for your response. This did fix my code, however it still does not show the checkmark in the dashboard if the table entries are correct. Is this possible? Currently it only shows a “dot” to mark that a response has been inputed, but not checkmark or “x” to denote an incorrect entry.
If you know of any work arounds for this please let me know. I apologize in advance, this is my first time using these measures.
I having trouble with my code on slide 6 of this activity I’ve created, I want students to write in factored form in the first column but when I use parentheses, the code will not register as the correct answer. I’m stuck with Row 3 of my table. Any suggestions on how to fix it?
I think it has something to do with the parentheses. I changed it to latex form and it worked:
cellContent(3,3): when table6.cellContent(3,1)="2\\left(3a-b\\right)"
You might want to put a warning in the note to make sure the students don’t put any extra spaces in the expressions. If they do, all these will get marked wrong. Checking latex can be a bit tricky. There are other methods, but you might not have time to change the code (depending on when you need to roll this out).
I usually use simpleFunction with evaluateAt and some countNumberUsage. Here’s what I came up with for the particular row you asked about earlier:
cellContent(3,3): when simpleFunction(table6.cellContent(3,1), "a", "b").evaluateAt(5,6)=18 and countNumberUsage(table6.cellContent(3,1), 2)=1 and countNumberUsage(table6.cellContent(3,1), 3)=1 and countNumberUsage(table6.cellContent(3,1))=2 "✅"
otherwise " "
For the evaluateAt(5,6), that means that if you take the expression that’s typed in the cell, 5 will be substituted for a and 6 will be substituted for b. I just randomly picked 5 and 6, so anything could go there (except don’t choose 1 or 0 because their properties could yield false positives). The countNumberUsages are looking for one 2, one 3, and only two numbers total in the expression. Also, we defined the variables in simpleFunction, so no other variables would be accepted.
The parseEquation reads the latex as an equation and the difference function subtracts the left side and the right side of the equation. Since there should be a “w” variable, if we substitute 52, the difference should be 0. This will allow for different iterations of the equation too i.e. w+w+76=180.
You could also toss in an errorMessage to make sure the correct variable is being used. This goes in the input too.
ev1 = simpleFunction(parseEquation(this.latex).lhs, "w").evaluateAt(52)
ev2 = simpleFunction(parseEquation(this.latex).rhs, "w").evaluateAt(52)
errorMessage: when isUndefined(ev1) or isUndefined(ev2) "Only use the w variable" otherwise ""
I learned from @Jay! I started by doing the CL scavenger hunt and then just kept learning by making activities. There are webinars that @jay has hosted that are archived somewhere in this forum.
For your question, don’t forget to mark the sketch as readOnly: true. For the input, try this:
correct = simpleFunction(this.latex, "a", "b").evaluateAt(5,5)=5 and countNumberUsage(this.latex,2)=1 and countNumberUsage(this.latex,3)=1 and countNumberUsage(this.latex)=2
For the evaluateAt, I just chose to sub 5 for a and b, which happens to evaluate to 5. You can pick other numbers too. I also look for one 3, one 2 (countNumberUsage only looks for positive values), and two numbers total.
I have quick follow up for you about this code for checking an equations most of my students wrote down the correct equations which was 2x+76=180, but I had a kid write w=52, which is technical correct but I was hoping to have it in a form “something” = 180 (or 180 = “something”) Do you have any suggestions on how to get it in that format?
