Next Button Control

I have been working on an activity where I’d like to prevent students from advancing until they have completed a task. The approach I’ve taken is to send them back to an earlier screen if there is a problem but it would be easier if the ‘next’ button could be disabled until a condition is met. So far, however, I’ve not found anything that suggests this is possible?

You’re right, that’s not possible. Even some Desmos created activities use your strategy of sending students back to the previous screen.

Pity, but thanks for the reply. Hopefully someone from Desmos will add this a change request list as it would be VERY useful.
