Duolingo needs an explanation part in each lesson.
German is quite complicated because of its grammar. I have many questions about the German grammar. I think Duo should add an explanation part in each lesson so the languages learner on Duo can understand the languages that they learn clearly. I would be very happy if the moderators add the explanation parts. Thank you !
There is an explanation part(in most languages). If you go to the skill, before you start a lesson, scroll down and it has everything you need to know!
In Duolingo's web version of the course "German for English speakers", only the skills which introduce new grammer have "Tips and Notes" on the bottom of the lessons page.
Yes, grammar tips are great online. I can't stand that the app doesn't have a way to access it for when I'm out an about. Of course, Google is one's friend... :)
Before you start a skill, scroll down to near the bottom of the page, and you should find some notes explaining the grammar and stuff.
