I copied this code to check if table contents was correct, and I was wondering what the purpose of the code from the word “correct” and below is ? It seems to work fine with out it. cellContent(1,3): when tbl9.cellNumericValue(1,2)=0 “✅” otherwise “❌” cellContent(2,3): when tbl9.cellNumericValue(2,2)=-8 “✅” otherwise “❌” cellContent(3,3): when tbl9.cellNumericValue(3,2)=12 “✅” otherwise “❌” cellContent(4,3): when tbl9.cellNumericValue(4,2)=-20 “✅” otherwise “❌” cellContent(5,3): when tbl9.cellNumericValue(5,2)=-40 “✅” otherwise “❌” correct: tbl9.cellNumericValue(1,2)=-3 AND tbl9.cellNumericValue(2,2)=13 AND tbl9.cellNumericValue(3,2)=-3 AND tbl9.cellNumericValue(4,2)=13 AND tbl9.cellNumericValue(5,2)=27 ---

You’d need to change the values, I think, but the `correct:` sink controls the teacher dashboard. If all correctable components are `true` for their correct sinks (or marked as `readOnly: true`), then the teacher dashboard will show a checkmark. If there are any ungradeable components (i.e. explain prompts or text inputs) which require a teacher to look at them, you’ll never get a checkmark, at best a dot. ---

Awesome…learned something new…I am just playing around with this for the first time. I was wondering if there was a way to control the teacher dashboard. Now I know! ---

content: “{message} {feedback}” message = “For the function shown on the left, what is the output when the input is 5?” feedback = when mthInput1.submitted and mthInput1.numericValue=9 “\n\n\n✅Good work ! !” when mthInput1.submitted “\n\n\n\n❌Wrong answer. Please try again.\n\n Remember PUT 5 in for x!” otherwise “” So the correct answer in text box “mthInput1” here will “9” …If I understand correctly, there is no way i can get a check mark on my dashboard if a student enters a 9 ? ---

disableEvaluation: true correct: exp1.numericValue=11.75 Will this do it? Again, this is my first shot at this…I appreciate the help. Not sure of the disableEvaluation means ---

Always easier for people helping you to publish and share your activity. You look like your mixing things a little (`mthInput1` vs. `exp1`). `disableEvaluation: true` means if a student types in a numeric expression, the input won’t evaluate the expression. Default it’s false, so if a student types “3\*5+16”, to the right in the input it will show “=31”. For your question about the message/feedback part. The teacher dashboard requires you to use the `correct` sink. So, if you wanted a checkmark when `mthInput1` is 9: ```auto correct: mthInput1.numericValue=9 ``` If there are any other components that _could_ be corrected (i.e. sketches, graphs, tables, multiple choice, etc.), they also have to have their `correct` sink used **or** `readOnly: true`, meaning it won’t be checked for correctness. If either is not done, you’ll get a dot instead of a checkmark because something has to be checked by the teacher. ---

i thought I would use the naming convention mthinput for math input box, but i definitely need to fine tune that as I figure out what is best. Thank you for you help!.. It worked perfectly ---

I’m trying to learn all of this and I’ve been copying and pasting with some adjustments from other activities similar to what I am trying to create. In this activity, the student has a table in which they need to write their responses as exponential expressions (2^2, etc.). I thought that I had all the code written correctly but I still can’t get a check mark on the teacher dashboard. I think the line that is affecting this is: correct: this.cellContent(3,3) = “`\\2^2`” and this.cellContent(4,3) = “`\\2^3`” and this.cellContent(5,3) = “`\\2^4`” and this.cellContent(6,3) = “`\\2^5`” and this.cellContent(7,3) = “`\\2^6`” Ideas on what my error is? Thank you! ---

You don’t need the double slashes, and it’ll be more accurate if you use backticks to check latex instead of quotes. ---

Note that this content check is for the 3rd column. The backticks Daniel\_Grubbs suggested will check this for the LaTeX expression instead of numerical equivalence, so 2\*2 or 4 will not be correct answers for 2^2 ```auto correct: this.cellContent(3,3) = `2^2` and this.cellContent(4,3) = `2^3` and this.cellContent(5,3) = `2^4` and this.cellContent(6,3) = `2^5` and this.cellContent(7,3) = `2^6` ```
