Credit: Matt Horne / Android AuthorityI’ve defended Duolingo more times than the app has probably deserved. After almost 1,200 consecutive days with the green owl, I still think its convenience and simplicity make it a useful learning tool, even if it’s still annoying in many ways and nowhere near capable of teaching you a language by itself. But that defense becomes harder when a Duolingo course update doesn’t merely annoy learners but leaves them unsure of what they have or haven’t actually learned. That seemed to be happening for some users recently, even though I didn’t particularly notice it myself. We wanted to know how many of you were negatively affected by the recent course upgrades, and we set out to find out.That was the theme behind our recent poll. We reported on the fact that the Duolingo course expansion appeared to have shuffled some users along their learning paths, with completed sections suddenly containing unfamiliar material and other learners being sent back to lessons far below their previous level. In that article, we asked whether these changes had negatively affected your progress in a poll, and you responded in your thousands. Let’s take a look at the results.
