Here’s a little challenge from me and @SarahMW. How would you validate a student’s answer on this screen? Make a copy of the activity and share your strategies here!
While you work on the challenge, think about how you can honor student thinking even on a simple screen like this one.
Here is my initial take on this: CL Day Prompt - Validating Feedback on a Line • Activity Builder by Desmos Classroom
The idea is to validate their equation both in terms of the correct answer and in terms of the graphed line, assuming there is a mistake in the plotting of the points. I tried to use different colors and some animation to try and show these things, but I think it ended up feeling a little too visually busy.
If I am expecting slope-intercept form, I might use this code in the CL:
function(f): when equation.submitted simpleFunction(equation9.latex)
otherwise simpleFunction(``)
I would then list f(x) in the graph editor and name the math response box “equation”. It would display a new line based on their equation after they click the Submit button.
It’s so pretty! And sometimes adding the extra feedback changes the repetition!
Will that check for slope intercept form or just that it is in y equals form? If they responded in y=m(x-x1)+y1 form, would the code you listed still mark as correct?
