I really wish there was a function that let me see how many points the students had earned over the past week. Then I could give a prize for the highest scorer of the week and boost their motivation.
Are your students using duolingo for schools? You can find it in the main menu it's blue and it has some smiling kids on it. Then put your kids in a class and you should be able to see their progress. Tell me if you have any problems! (｡◕‿◕｡) Have a nice day!
