DuoLingo, what is the status of fixing the hack?
I know many teachers have requested this. This is extremely important for the integrity of DuoLingo. Maybe DuoLingo could make a button that pops up for teachers when a student turns their wifi off and uses the program. Thank you!
We are currently testing and tweaking a number of different strategies to help us deal with users turning off/losing wifi in the middle of a lesson. As soon as we have determined the best strategy, we will release it to all users, which should close the wifi loophole for good. :)
Short answer: no worries, you are not doing anything wrong!
Longer answer: Duolingo has always made it a priority to make our apps and website usable even with shaky connectivity. Early on, we decided that if a user lost connectivity during a lesson, they should not be penalized. Our original approach was to give the user the benefit of the doubt and mark any answer as correct if, for some reason, the app/website could not reach the Duolingo servers to grade the answer. We have since found that this is being exploited by some users, and makes it difficult for teachers to determine if their students are actually practicing or just turning off their wifi and typing in bogus answers. (This is the loophole :))
To fix this, we have implemented an algorithm that can grade answers without having to go to the Duolingo servers. Users will still be able to continue practicing if they lose wifi, but it should no longer be possible to cheat because wrong answers will now be treated as such. We are currently tweaking the algorithm to make sure it does not negatively impact the learning experience, but we are hoping to release it soon.
